Is 2560x1440 resolution (WQHD) supported over HDMI in OS X Mavericks?
Hi, just bought a Dell UltraSharp U2713HM monitor and connected it to my Mac Book Pro (Retina) by a high-quality HDMI cable.
Unfortunately, Mac OS X sets the monitor at 1920x1080 resolution instead of its native res 2560x1440.
The specs for the MacBook says it supports up to 2560x1600 resolution.
My questions are:
Is there anything different about HDMI cables that alloiws some to support HDMI 1.3a or 1.4, but not others? It's a high quality Cambridge Audi cable, but was bought a few years back. It has no numbers on it.
Does the MacBook Pro hardware support HDMI 1.4?
Does Mac OS X Mavericks 10.9.1 support HDMI 1.4?
If so, I should be able to achieve 2560x1440 at 60 Hz. If not, is it possible to set a lower refresh rate in order to achieve the panel's native resolution?
The HDMI video output support for 1080p resolution at up to 60Hz. To free your thunderbolt port you would need a USB 3.0 4-Port Hub and a USB-to-Ethernet Adapter to connect your MacBook Pro to the Ethernet network. The DisplayPort is capable of driving your display with 2560×1400 resolution.

I purchased a 2013 MBPr 15" (the first Mac I've ever owned btw) and so far have enjoyed the experience. I purchased a large 27" high resolution 2560x1440 non-Apple display which I planned on using HDMI output for, since HDMI has no problem supporting this resolution. After receiving this display yesterday I came to the sad realization that OSX does not support 2560x1440 over HDMI. However, under further investigation I found that Windows7 in Bootcamp on the same machine will beautifully display the full 2560x1440 over HDMI.
This means that OSX is the problem, and not the MBPr since Windows7 displayed the full resolution with no issue. If the hardware can support it, why would Apple disable it in the software? Is this just their way of forcing people to use DisplayPort? Or is there hope for them fixing this in future versions?OK. No reason to be playing games here. Just surprised that this issue hasn't been brought up here on the community boards as well. Here's the simple solution

Re: Why can't my Belkin Thunderbolt Express Dock operate my desktop speakers?

After reaching a Level III technician in Belkin customer support today and having spent approximately 4-5 person hours on this issue, we figured out that the Sound/Output preferences in the Apple System Preferences should not be set to "Internal Speakers" but rather set to "USB PnP Sound Device".
Worked like a charm. Simple, elegant solution to a real problem, one likely to be encountered by 90% of the people who buy a Belkin Thunderbid Express Dock off the shelves of any Apple Store to use with a current generation Apple laptop or desktop computer.
But the Level III Belkin technician admmtted that this critical little piece of simple, straightforward information should have been readily available to their Level 1 techies who began helping me 5 person hours ago. Would even have saved Balkin loads of customer service support time.
And so the saga ends
Belkin owes me for helping them learn this precious lesson.

Connecting 2560x1440 screen to a U410 over HDMI
Hi, Im a new owner of U410 IdeaPad.
I bought this machine with the intention to hook it up to a WQHD (2560x1440) screen.
The screen I intend to get has no limitation on being fed over HDMI with this resolution (supports 1.4 HDMI).
What I have found out is that I might have a problem with the machine not supporting this resolution over HDMI.
My question is whether U410 with its dedicated Nvidia 610M (in addition to HD4000) sitting on Intels HM77 chipset will allow me to output WQHD resolution over the HDMI, or at least wether this HDMI connection is of 1.4 version.
Thank you very much.Thanks for the reply
can you reference me to the source/s which confirm the 1.4 support (I'm a bit uptight about it since I am going to order the screen online without the option to return so I don't want to find myself owning a 27" HD-TV instead of a WQHD screen).
There is apparently an issue with HDMI and above 1080 resolutions, a few manufacturers (of both chipsets and monitors) made a bad assumption that HDMI = 1080p for the home user even though the interface can support more then that but they capped it at 1080.
For example

[Solved] A75A-G35 gives no video signal over HDMI, resolution over DVI limited
Hello community,
following problem: I have been using my A75A-G35 board with an A4-3400 Llano APU, the APU has been connected to a 19" BenQ FP91GP monitor via a DVI cable. I got its maximum resolution of 1280x1024 with no issues.
Now I have purchased a 24" Dell U2415 monitor with a maximum resolution of 1920x1200 and wanted to connect it to my computer. However, I got stuck:
1. I get no signal whatsoever using the HDMI output and a HDMI>HDMI cable. I have tested a different computer and connected it to the Dell with the same cable successfully, so the cable and the monitor should be fine.
edit: Disregard the following as the problem with the DVI cable appears also with the other computer. The problem is therefore just the fact that the HDMI output of the board doesn't work!
2. I get a signal with a DVI>DVI cable + DVI>HDMI adapter. I can access the BIOS, the boot manager and see the boot screen, however once the desktop should be displayed the screens turns black and the monitor keeps switching to standby and back on again, the screen staying black all the time, however. But before installing the driver package (for chipset and video, downloaded from the MSI website), I could see the desktop with a resolution of 800x600. Also, if I boot into safe mode, I can see the desktop and increase the resolution up to 1280x1024. Higher resolutions up to 1600x1200 are available, however selecting any of them results in severe screen flickering.
3. If I boot my Linux install, I have almost the same behaviour. I see the boot messages but then the screen turns black when the desktop should appear. However, if I connect the old BenQ monitor to the VGA port, I get a signal on both screens, however both screens have the resolution 1280x1024 and I cannot increase the resolution of the Dell, because if I try to, the screen turns black again. Lower resolutions than 1280x1024 are possible, though. Note that the "second monitor trick" does only work with Linux, with Windows I get only a black screen on both monitors.
As a side note, the DVI cable I'm using is a DVI-D single link, so the maximum resolution it supports is actually exactly the resolution of the Dell, 1920x1200.
Thanks for any hint,
Photonyour welcome!
when you said your problem and the symptoms I thought that board sounded familiar as alot of people when it first came out that we had to explain that to them so I had a look and yes it had the jumpers to switch ports for its digital display display signal to be routed to another port so i thought that was the cause!
have fun with your board now you have it in HDMI mode! -
Does Nvidia GT 120 support 2560x1440 Resolution
Hi from Germany,
I have an MacPro 4,1 Intel Xeon QuadCore, running two wonderful NEC Multisync P221W 22" monitors with 1680x1050 px resolution.
For I am working in the motion graphics business it is always no fun to work on video-spots with for example 1280x720 pix (HDTV) on an 22" monitor.
So I would like to upgrade one of the NEC monitors to a 27" monitor with 2560x1440 resolution and I would like to be sure, if the graphic card will support the two monitors.
Thanks in advance, AndyNVIDIA GeForce GT 120 includes two video ports: one Mini DisplayPort and one dual-link DVI port. This allows you to connect both the 24-inch Apple LED Cinema Display or another Mini DisplayPort-based display, and a DVI-based display such as the 30-inch Apple Cinema HD Display. Display adapters are available to connect VGA displays.

I am trying to connect my MacBook Pro (early 2011 w/ Intel HD 3000/ 384Mb) to an external display with a 2560x1440 resolution. Specifically, what cable/connections do I need to display at this resolution? I cannot get the display to work using a "Thunderbolt to HDMI" or a "Thunderbolt to DVI" connector. Note: I used both older and newer (uni-directional) HDMI cables on the first config, and a Dual-link DVI cable on the second config. Apple specs state this is possible ( support.apple.com/kb/SP619 ), but I am at a loss as to how this can be done. Thanks in advance for the help!
You use a Mini DisplayPort to either HDMI or dual-link DVI adapter. If that component doesn't work, something's wrong with either the cable or something else in the connection.

5.1 Surround over HDMI: Solve one problem, another rises up.
UPDATE 1: After a good night's sleep, and after doing a bit more reading on alsa-project.org (big props to this page), I managed to get a much better ~/.asoundrc together. It solves all my problems, and I can do everything I need. I've preserved the post below in case anyone else runs into these issues, and I'll post my solution as a response to this post.
UPDATE 2: Looks like I celebrated too early. Got more strange problems. Screw it, I'm going back to PulseAudio. I just wrote a wrapper script to kill and restart Pulse for applications that really, really need ALSA.
Okay. I've almost completely worn out my fingers trying to get this working. I feel like I'm playing Whack-a-Mole. This is a bit of a lengthy post, but I'll try my best to describe every problem I've encountered in as much detail as I can, followed by the solutions I found, followed by the problems each solution brought with it. By going through everything this way, mole by mole, hopefully it'll be easy to follow along and help me come to a universally working solution.
Summarized Version of Problems:
5.1 surround works only on specific applications which are robust enough to allow me to manually specify audio output options, and only if ALSA isn't configured at all
once I've configured ALSA, sound works on every application, but it's all downmixed to 2.0 stereo from this point on
installing PulseAudio lets me choose 5.1 surround as a default, but brings with it its own problems and drawbacks, namely the lack of passthrough support for encoded streams
Long-Winded Version:
I have my computer connected over HDMI to an AVR with a 5.1 surround speaker system. At first, I didn't have anything configured in ~/.asoundrc (or its global equivalent, /etc/asound.conf). Neither file existed, so everything was running off defaults. I got the name and device number of my card from aplay, ran speaker-test and played a six-channel test file in mplayer.

Everything seemed well, all six channels played from the correct location on both tests, but I did realize that the device number of the card was 3, not 0. A lot of applications that aren't as configurable expect the default card/device to be set properly, and audio won't work in those applications without specifying that in ALSA's configuration. Knowing this, I set the following in my ~/.asoundrc:
pcm.!default {
type hw
card HDMI
device 3
ctl.!default {
type hw
card HDMI
device 3
This, however, ended up causing more problems. Oh, it made sound work on everything by default after that, but only for one application at a time! That surpised me, as I thought ALSA's big advantage over OSS is that it can multitask. Running the speaker-test the way I did earlier turned out fine, but when I tried playing that test file in mplayer, things got weird again. Here's the output from mplayer:

Why the hell is it looking for pcmC0D0p? It should be looking at pcmC0D3p. Did it not get the memo from ~/.asoundrc? Urgh.
I've also tried '-af channels=6' in place of '-channels 6' but the same result happened. It does the same thing without the '-ao alsa' option, I just specified it to trim down the output, so that I wouldn't be copying and pasting all kinds of other errors about not finding OSS or JACK or other things I don't have installed.
If I symlink /dev/snd/pcmC0D0p to /dev/snd/pcmC0D3p, it'll fix the problem, but that feels like one ugly kludge. I'd have to do it again over and over every time I reboot, too.
Not sure if this would help matters or not, but if anyone knows how to change my card's device number from 3 to 0, I'd like to try that as well, but I'm not sure how to do that sort of thing. I'm just guessing it might be worth trying, since everything looks for card0/device0 by default, and that kludge I tried earlier did have an effect, so maybe if we can just switch those device numbers with each other, everything would work smoothly without having to force anything through ALSA's configuration at all. I believe card0/device0 belongs to the Host Bridge... is there a way to have them trade their device numbers for one another's in a safe manner?
I can also get it to play if I specify the device like I did in my first test, using '-ao alsa:device=hdmi', but that defeats the purpose of getting good defaults set if I still have to set everything by hand before I play something. If I try playing the test file without any options, like so:
$ mplayer Nums_5dot1_24_48000.wav
... it will play, but only in two-channel stereo, and the parts that should happen in the center, rear and LFE channels get downmixed into the left and right channels.
I can get it to work in aplay, though! All six channels! Not that I plan on using this as my primary multimedia software.
$ aplay -c6 Nums_5dot1_24_48000.wav
The only solution I found so far that allows me to have 5.1 audio by default is to install the PulseAudio server, which is able to find a sink/source named 'alsa_output.pci-0000_00_03.0.hdmi-surround' and lets me choose that as my default. Only problem with this is that PulseAudio has its own problems.
Aside from the crackling sound issues in some Wine games, Pulse also has a much bigger drawback -- a complete lack of passthrough support, meaning I can't use encoded streams such as Dolby DTS and TrueHD with PulseAudio. I have a Harman/Kardon AVR and I'd like to get my money's worth out of it, so I'd really like to figure out a solution in ALSA without using Pulse at all.
Does anyone know how I can have my cake and eat it, too? I just need 5.1 surround, by default, in ALSA without PulseAudio.
HUGE thanks to anyone who tries to help here. This is really making me sad and frustrated, I've been using Arch for quite a while now and this is the first real big stumper I've come across that forced me to post a thread. Otherwise I've been having a wonderful time.
Edited because I tried something different that removed *some* issues, but the above problems still remain.
Last edited by Rybelda (2014-10-27 22:10:24)Well, I thought I fixed it doing this...
pcm.!default {

buffer_size 38400
... but then realized it strangely makes applications that run at 640x480 have no sound at all. No idea why the video resolution is screwing up the sound, but that's what's happening, because if I set the resolution any higher, the sound comes back.
I'm going back to PulseAudio, I feel like ALSA is mocking me. I wrote a wrapper script for the few times where pure, Pulse-less ALSA will be necessary for me. Here it is, in case it helps anyone else. I've tested it with XBMC, it turns off Pulse and allows ALSA to pass through encoded streams unhindered. It also works with some Wine applications that have scratchy audio glitches in Pulse.
#!/bin/bash
echo "autospawn = no" > $HOME/.config/pulse/client.conf
pulseaudio --kill &> /dev/null
"$*"
rm -f $HOME/.config/pulse/client.conf
pulseaudio --start &> /dev/null
I'm removing the SOLVED tag because technically I didn't resolve any of my original issues, I more or less gave up on what I wanted to do and found another way to satisfy my needs, but it still isn't as elegant as I had hoped for. In any case, I'm done with this issue for now and the forseeable near-future, but if anyone has anything further to add, feel free.

Mac mini 09 Display Resolutions odd via DVI -- HDMI
Hi I've got a LG 1366x768 commercial display and it works great with an Apple TV, MacBook 2007 or MacBook Pro 2008.
However when I unplug the MacBook and plug in the New Mac mini, it gives a completely different set of resolutions - none of which work properly on the display.
When overscan is chosen on the Mac mini, it chops off the top of the menu bar. Overscan is on the MacBook and MacBook Pro and it looks perfect.
Everything is blurry no matter which resolution I choose on the Mac mini. Everything is crisp with the MacBook and MacBook Pro. This is a serious problem....
Tried switchresX and it's no help.
Anyone else using one for their home theatre with a HDMI setup?Which LG model is it? Which HDMI jack (HDMI1, HDMI2) on the TV are you plugged into?
Some LG commercial TVs have a different internal mode for the inputs that has to be changed in the TV menu. If it thinks it is a true HDMI signal, it will automatically overscan it for you resulting in things being cut off and looking fuzzy. You have to convince it that you really want to be a PC type input that just happens to be over HDMI in order for it to display on all visible pixels. Depending on the model, you may have to plug into a specific HDMI port to even make that possible. -
Cannot display the screen of my macbook on TV. OS is Lion 10.7.2. The Macbook is connected to the TV is over HDMI cable. TV shows only the backgroud picture of the Lion OS and reacts even to mission control. Do you have any suggestions for help ?
You have the display set in Extended Desktop mode. In System Preferences>Display on the MacBook screen there should be an Arrangement tab when you have the MacBook hooked up to the TV and both screens working. When you click the Arrangement tab do you see two monitors side by side? One of them will have a Menu Bar at the top. Just click on the Menu Bar and drag it to the second monitor. That will make the second monitor your main screen. You can now use your MacBook in Clamshell Mode with a wired or Bluetooth keyboard and mouse. http://support.apple.com/kb/HT3131 When you disconnect from the TV your Menu Bar will automatically change back to the MacBook.
Or if you want to work on the MacBook screen while showing it on a TV you can check the Mirror Display box on the lower left hand side of the Arrangement tab under the two monitors box. -
*Qosmio G50 No sound over HDMI*
Hi all,
Hopefully anyone recognises the following and would be so kind to help me. I have searched the forum and tried severall of the offered solutions mainly applicable to Vista, but still.
I hooked up my Qosmio G50 to my Philips LCD by HDMI cable. Picture is ok but there is no sound. I tested the cable with a Toshiba Satelite Pro L550 and it works allright. Picture and Sound are working. But that laptop has Intel HDMI audio.
I'm running Windows 7 Home Premium 64 bit. I upgraded by Toshiba update DVD from Vista 64 bit. Sadly I do not know for sure if HDMI audio did work before that. I think so because I did use the laptop for watching a movie on a Panasonic plasma. But I can not remember if that was before or after the upgrade.
Realtek HD Audio device is installed driver version 6.0.1.5923
Realtek HDMI Output is selected als default playback device.
Testing gives me graphical response ( the indicator flashes ) but no audible sound from my tv.
Choosing the other audio device Realtek Digital output changes nothing and I do not believe that this would work anyway.
I have tried removing the device and reinstalling the original drivers. I have tried REaltek drivers from their website.
I have tried changing the view to HDMI only but that does nog change anything either.
One thing that worries me is that under Sound / Realtek HDMI Output / properties / Supported Formats there are no formats present. The Satelite gives me DTS audio and some other. So I am wondering if there should be formats present and if so how can I change this / add any.
Please forgive me if there are errors in the text. I am translating this from a dutch language version of Windows 7.
Please help me. Any suggestions are welcome!Jeka-?? & PinkPanther thanks for your replies!
The solution for the G30 you mention is not the one for me I am sorry to say. I have tried that one allready. Windows automatically switches on the HDMI audio out when I connect an HDMI cable. Connecting the cable before switching on the TV and laptop is a good thing to try because it eliminates possible problems with the connection. The connection in my case is ok.
At some point I concluded that there must be a softwareproblem of some sort.
I have found the solution over night. Could not sleep anyway. I did not know that the videodrivers are also handling HDMI audio out but in a way it makes sense. I have completely deinstalled the NVIDIA video drivers. After downloading the latest drivers and installing them everything works absolutely fine! -
Force RGB over HDMI connection??!! (Dell U2414H)
Since Apple's support refuses to help me, nor do they seem to grasp incredibly basic technical information regarding monitors, I'm turning to you, dear forum.
I just bought two brand brand and professional calibrated Dell U2414H monitors to use with my Mac mini workstation in an extended desktop environment. ...even though Apple themselves erroneously told me I'd be able to daisy chain these monitors over the Thunderbolt connection using MiniDisplay Port 1.2 MST... (they were wrong, their GPU doesn't support DP 1.2)... So, I resorted to plugging the second monitor into the available HDMI port.
Problem: The Mac OS will not send the right color space (RGB) over HDMI. It sees the monitor as a TV for some reason, and will only send YPbPr... Therefore, my monitors that I paid extra to have calibrated perfectly, do not match.
I ran this script: http://embdev.net/topic/284710#3027030
but it didn't change anything. I'm searching for new solutions now...
Can anyone help?Here... I solved it:

Dell 2408WFP at mac mini over hdmi
I have an new mac mini server, where I try to connect an Dell 2408WFP to over hdmi.
Besides the problems with shadows around the letters in written text and menus, which I solved by setting the resolution to 1600x1000, I have a big color problem, which I can't solve by any calabrating procedure. Green and blue colors are dominating, and all brown to red colors are reduced or missing. For example the Icon of the addressbook appears not in this standard beige color but in green. As you can imagine, this is the absolute kill for any work on images. Since the Dell monitor is a good standard one, which I never had any problems with before, there must be a problem with hdmi ore even worse with the graphics of the mac mini.
Has anybody similar experiences and found a solution. I bought the hdmi cable expecting to have the best connection possible then, and to have only one cable between the mac mini and the monitor. Are there any limitations in the hdmi-standard concerning resolution and color management? I didn't test any dvi cable yet, since I am still hoping to find a solution for this problem.I have exactly the same issues as you, ie the lack of clear / sharp text and the colour management problem. Did you get anywhere with this?
I was using this Dell display with Windows 7 and had none of these problems. I calibrated the display using a semi-professional calibration utility (i1Profiler / Eye-one Match) and the results under Windows were great. But with the Mac Mini I find that many colours lack saturation. Yellows are very faint, and reds look more like a brown-orange. I tried replacing the HDMI cable with a DVI cable and the Mac HDMI -> DVI converter but I don't see any improvement.
Interestingly I find that the text looks best at the monitor's native resolution, ie 1920 x 1200 but it's still nowhere as crisp as text is under Windows.
For me the colour management issue is the biggest problem. I do lots of underwater photography and I just wouldn't dare work on any of my photos with the display as it is.
The profile I find works the best is sRGB IEC61966-2.1 but it's way off being natural / correct.
I specifically bought the Dell display as it has variable height and fits neatly in the corner off my office where the height is limited, I don't have room for a 27" thunderbolt display even if I could find the funds (~$1600 in the UK!)
I'm running 10.7.2 (Lion) in case it makes a difference. -
720p over HDMI - black bar issues
Hi all.
I've got a 1st gen V-box, which worked great until about 9 months ago. I had been happily using 720p over HDMI for about a year. However, I suspect a software "update" around this time caused problems, as the 720p and 1080i settings are now incredibly unreliable.
Specifically, when I set the box to show HD resolutions, there are usually black bars down the left and right of the screen, cutting off those sides of the picture. Sometimes the picture displays properly, but this is usually only temporary - after a day or two of thinking everything's sorted, the dreaded black bars reappear when starting the box up for the first time that day. Rebooting doesn't seem to help. The bars even overlay the menus, so it seems to be affecting everything not just live tv. The full picture is shown when I use standard def over HDMI however.
Has anyone else experienced this and if so any ideas how to fix?Hello
On most platforms, I've experienced black bars at the sides, noteably lower bandwidth channels such as kids or shopping often display what you describe when using any HDMI setting in my experience.
Thre is the ability to hit the shortcuts button on the bottom right of the remote which allows you to scroll through to then stretch the image if you wish- but It doesn't always work, I'll stress again this also happens on my FREESAT box, so I don't think it's an issue generic to Vision.
Couple of questions though,
1: Is it a Toshiba tv? (some firmware upgrades to these sets have caused numerous issues and lip synching problems.
2: have you tried a different HDMI cable? (apologies if that's blatantly obvious!)
I've not tested V.1.5 black box yet to see how this issue is there (note I don't call it a V2 box- as it's **bleep**).
Hopefully, if the rumours are true the development team will scrutinise the forums, realise these issues do indeed exist and can work towards a solution in the Freeview HD offering of whatever comes out next:

Don't have 2560x1440 resolution on Dell U2711
Hi,
I've recived the mac today and I have a monitor DELL U2711. The monitor is connected with an HDMI cable.
This is what I can set now.
Someone know what I can do to get 2560x1440 resolution?
Thanks
Ivanyou could try to option+click on "scale" to find out more options.
but i fear that won't solve the problem, at least this is my experience as I am in the same situation
It seems to be a problem of Mavericks. (Lion worked perfectly with the maximum resolution
Both my MBP and MacMini can't get 2560x1440 on the U2711. And yes @turbostar - with mini DP to DP.
All those work-arounds (reset PRAM, overwrite the overrides ...) don't help. So very, very VERY frustrating.
So if any ouf you finds the solution. please post here.
