After 10.5.7 HDMI connected 24" Monitors only allow 1080p
After 10.5.7 update my 24" LG L246WH monitors which are connected with HDMI / DVI-D cables to the NVIDIA 8800 GT only allow 1080p and the monitor list doesn't show the 1920x1200 resolution anymore.
Now I have to use the DSub connection with VGA cables and DVI adapters to get back to my normal desktop settings.
Why this ?
Having the same issue, but with a MacBook 2,1 and a HP w2408h, connected to HDMI with a HDMI-DVI cable on a Mini-DVI to DVI adapter (this display has no DVI port, the HDMI port is the only digital input it supports).
Prior to 10.5.7 I could run the native resolution of 1920x1200 just fine. Now the system insists that 1080p is the highest resolution possible.
This is definitely a global regression in the way OS X handles monitors connected using HDMI. Not driver specific.

MBP via HDMI to 24" monitor only runs the monitor not MBP display??
I own a 2008 Macbook Pro 15" from 08.
Have used monitors in the past but none via HDMI.
Recently got an Asus VE247H 24" monitor.
Connectd via DVI or VGA it works with a terrible screen resolution but i can still use my MBP pro display as a second monitor.
When using HDMI the resolution is great at 1080P but i cannot use my MBP display as a second monitor.
When using HDMI to mini display port am i limited to just 1 monitor?

HMDI Connected External Monitor only works mirrored
I've got a 27-inch iMac with the 2.93 Ghz Intel i7 (running Mac OS X 10.6.5) connected to a Hannspree HF289H 27.5in external monitor (1920x1200 resolution, connect via Mini Display to HDMI adapter and an HDMI cable). It has worked fine for a few months, but all of sudden the 2nd monitor will just go black. When I restart the computer, the 2nd monitor will flash on and off and resize, but will not show anything once the computer fully comes up. If I go to the monitor settings and choose to "mirror" the display, it comes on and works. Then, if I take it off mirrored, it will work for a matter of minutes to hours, but eventually go black again.
Any thoughts? I've already tried resetting the SMC and restarting with a PRAM reset as mentioned in other posts.Are you using the method in this Apple article? If you do, it should work.

My MacBook Pro (newest model in 2013 so far) does not sense external monitor (Panasonic HDTV in my case) via thunderbolt-HDMI connection...Is update 10.8.3 helping anyone else who has this issue? I returned my multiple HDMI adapters after figuring out it had to be an Apple issue n not the adapters so I can't check it myself now.
Thanks!I have late 2012 MBP 13" and connect to my Panasonic Plasma correctly.
But using the same cable, can't connect to an LG 47LM6200, the MBP detects the TV, the screen blinks blue, but the TV shows "no sinal detected" message. -

You can have one HDMI (or DVI monitor via HDMI to DVI adopter) on the HDMI port
Another monitor via one Thunderbolt port and suitable adopter if not a displayport/mini displayport monitor
And use the other Thunderbolt port for Ethernet via a Thunderbolt to Ethernet adopter.

can i connect two monitors to my mac book pro with HDMI?
I retract my previous "No." If you can live with limited performance (slow refresh/choppy action video/no gaming) on the second external monitor, you could use a USB video adapter and a DVI-HDMI adapter to connect it to a USB port on your computer.

Just a note about the system information that appears below your post: iOS 4.3.3 does not run on Macs, only on iPods, iPads and iPhones. When you're posting about your MBP, it would be more useful to those responding to know which version of Mac OS X you're running. Doesn't matter for purposes of this post, but something to remember for future posts. -
i need to connect my Imac 27'' (newest version) up to 3/4 monitors (all 40'' LCD tv's with VGA and HDMI connections) with extended display to all external screens, not duplicate images. Is this possible?
I would suggest you visit an Apple dealer, preferably an Apple Store if there's one in your city, and ask for assistance in determining what you need. The questions and issues you bring up are rather complex to address in a technical support forum and would be better addressed in person where you and the salesperson can ask questions back and forth to arrive at the optimal setup.

My Thunderbolt to HDMI connection isn't working anymore.
I've had my MacBook Pro for about a year now (2.4 GHz i5), and I've been using a Thunderbolt to HDMI adaptor to connect to my Sharp 32" LCD with no problems since I bought it...until this week when I updated all my software/OS. Now, I can connect, the displays prefs see the monitor, but all I get is black. No sound either...even though the sound prefs recognize the HDMI connection.
I know the problem isn't the cable. It used to work, and it still actually connects this same laptop to my projector...but it won't display on my TV anymore. I even get sound on my projector. It works like my TV used to. The problem started with the update, so I want to know what changed...and when Apple plans on fixing it. These are not cheap computers...I am kind of embarassed that I have to use my gf's $350 Acer to play Netflix on our TV when I have this multimedia monster gathering dust.
This problem is extremely frustrating, and I've been doing some research on it. It seems like quite the problem for a lot of people! There are multiple unresolved discussions on here about it (some of them over 40 pages long!) and I can't really believe Apple isn't dealing with this. It's been years now since this started happening, I guess.
We're mac users...we need multiple displays, and we need this stuff to keep working when we update! That's why we've made Apple into the richest corporation in the world. Step up superstars...fix this!
Again (just to be clear) I know the problem isn't the cable, so don't tell me to go get a different one, or that it's the issue. Me and my gf basically wore out Netflix with this very laptop and cable up until this week, and I've never had an issue with it..ever, until this update (to OS 10.7.5). Everything is in good shape, and if the laptop/computer is still feeding to my projector just fine...there's something else going on here, and I think a lot of people would love to know what it is. I am not the only person this is happening to, and it's been years since people have been begging Apple to fix this!
I hope that Apple looks into this and puts these discussions to rest. There are a lot of them! Do a search! The "More Like This" box on the right here is FULL of very similar UNRESOLVED discussions. This should be a priority. You've all made enough money off us...now make your stuff work like it's supposed to and close these threads!No, I am a media professional who uses his MacBook Pro to connect to external monitors, and needs to continue to do so. I don't want Apple TV. I want my laptop to work again, like it's supposed to. Like it used to.
I have a demonstration this week at work that requires me to plug into an LCD screen and I am hoping to have this resolved by then. I am trying to convince my department to buy a Retina Mac and thousands of dollars worth of video software for live shows, and if I can't make it work, then I can't exactly convince them (or myself) to buy what I have been researching.
Again, I don't want wireless video or Apple TV. I don't want to buy any more stuff. I want to know why my Thunderbolt to HDMI cable stopped working after my update, and how to fix it...preferably before this meeting. -
Thunderbolt to hdmi connection
Hello I'm trying to connect my macbook pro 2012 to my samsung tv as a monitor. I have a TB cable that has an HDMI connection on the other end. I'm thinking i need an actual adaptor that converts signal, not just a cable that connect one to the other? As of right now when I connect the 2 nothing at all happens. Thanks and sorry if this has been covered a million times.

Qosmio G30 - external screen via HDMI connection - bad resolution
Hi! This problem is driving me crazy, please help if you can...
I have just bought a G30-102 and I'm trying to use it with an external screen via the HDMI connection. The problem I'm having is that the native resolution of 1920x1200 cuts off the edges of the desktop and the quality looks terrible - its almost like the whole screen is zoomed in. I tried this with a BenQ FP241wz at first (which is 1080i 1920x1200) and the Toshiba helpline couldn't find a solution either - even after painfully reinstalling all of the drivers etc.
Its been going on for so long, I thought that I would try it out with my HDTV instead, just to be sure it wasn't a monitor issue. So I tried it with my Toshiba 32WLT66 - and have just found that it has exactly the same problem.
All of the display settings appear to be correct and the G30 is convinced that the output is correct, so the question I have now is - do you think that its a problem with my HDMI port?
Please help, I'm a designer and it is essential that I use the machine on a large screen. If this is a problem with the G30 hardware I need to talk to Toshiba immediately about replacing or fixing it.Hi - thanks for the reply!
My BIOS doesn't allow me to choose much for the display - just between PAL and NTSC really.`As for the document, thanks for the link - unfortunately though there wasn't anything in it that I haven't already tried.
What would be the most obvious thing that could be wrong? Faulty port? Faulty card? Or could it even be as simple as a faulty HDMI lead? -
How to connect two monitors using macbook pro?
Hi,
I have a Macbook Pro through which I want to extend the displays to two individual monitors.
The two monitors should show two different windows which is opened through my macbook.
I have observed that macbook has only one mini display port through which I connect to HDMI or to DVI ports in monitor.
So how do I connect another monitor source to my macbook, which ports can help in this situation?
The monitors I have which can supports HDMI,DVI,VGA and DP ports.
Could anyone help me on this issue.
Thanks.You can use a USB 2.0/3.0 to HDMI/DVI interface. You might also consder Thundebolt to HDMI/DVI.
The MBP 13" will support three screens (two external) and the MBP 15" will support four screen (three external).
