Notable quality difference for same screen connected via HDMI or VGA

I have created the following topic:
https://bbs.archlinux.org/viewtopic.php?pid=1386998
in which I was trying to get help for a strange color anomaly on my screen.
Finally I found out that when I connect with VGA, this color anomaly doesn't occur.
I wonder why the VGA cable is working better than the HDMI?
I'd like to use HDMI because of sound.
But I'll stick to VGA for now as long as I can avoid issues...
Any idea why the HDMI cable is failing me?
The cable is new
(I think I also tried another cable, and I think I had the same issues, but not sure anymore).

Hi thanks for the response! Unfortunately the unit had to be RTB (Which took ages) and they said they had to swap out the board!
The support wasn't too bad initially but failed to advise it was heading from the UK to Germany for repairs - after a number of weeks it just turned up with no prior information. In fairness it has resolved the issue. I have Windows 8.1 and it works a charm for my uses - Media centre and some mid level video editing and have been fine just boosting the RAM to 8GB. While the SSD would be a nice option as I have 1TB internal and ext HDs on USB 3 it hasn't been a neccesity as performance for the majority is great! The only thing I'd have liked would be a juicier graphics card! I had a few issues with LAN and WLAN but managed to get this working (Its something to do with the compatability of the drivers with the graphics card and windows 8 - simply uninstalled the new driver and hunted down the original! Now for the most part the system is great! Good luck as you shouldn't have to use an older OS just to have it working!

My connection via hdmi to my TV is no longer working. Even if I use a thunderbolt to hdmi converter

Hi, the day before yesterday I turned on my tv which was connected via HDMI out on the mac mini to HDMI in on my TV. Everything was working fine, however I have been trying to set up dual monitoring on another monitor using an HDMI to VGA adapter to my second monitor but nothing was working. I was about to watch a film from the mac to the TV wen I thought it might be the resolution on the hdmi out why it wasn't working on the monitor but was on the TV so I changed the settings and the hdmi to the TV cut out. My main monitor is connected by thunderbolt to VGA adapter and works fine. I can change all the settings for screen resolution on the main monitor and have tried every setting on it then unplugging and plugging in the hdmi cable from the mac to the TV. I get the blue flash on the screen so I know it is being detected but here is where it gets weird.
I figured I would try the thunderbolt to HDMI converter I originally bought for my iMac and again the blue screen flashes up but there is no blue flash or any sort of detection on the TV.
The whole time there is nothing showing up on the screen, even when I unplug my main display from thunderbolt to VGA (the main monitor) and connect the thunderbolt to hdmi adapter and plug in the hdmi to the TV.
I know it's not the hdmi cable as I have tested it on my youview box to my tv and it worked fine.
I also know its not the tv as iv connected my friends windows laptop to the TV using the same cable so it must be the settings on the mac.
I have tried doing a time machine restore to the day I bought it and have had no problems so far until I changed the settings. Why oh why did I mess about with it!!
If anyone can help please let me know ASAP.
It doesn't show up the HDMI output in audio anymore either, however like I say it flashes blue wen I connect the hdmi but seems to have no idea that the HDMI is connected in the display settings! It's so frustrating. I'm going to call the mac support today but if anyone on here hash as any similar problems n fixed them please let me know.
Btw I'm running Mac OS X 10.8.4. I know I can connect via a long VGA cable but that's not really the point. I, at least would like to get my mirrored desktop on my tv back from HDMI!

Ok so I happened to figure it out while on the phone to apple support. Even though the guy was very nice, I think I knew more than him! He was explaining very basic resolution principles I played about. I had the second option in displays resolution. All I did was unplug the HDMI cable, click on 'best for display' then plugged the HDMI in and my resolution on the normal monitor changed to the normal blue, then went black momentarily and then changed to a strange resolution but another window appeared that said SONY BRAVIA HDMI at the top! Hey presto! Don't know why it didn't do it yesterday - I probably left the HDMI cable in or something! Oh well. Problem solved!

How do you switch output sounds set to my external monitor that is connected via HDMI.

How do you switch output sounds set to my external monitor that is connected via HDMI.

Hello gail from Ajijic,
If you'd like to change the audio output of your Mac, you can do so by accessing the Sound preferences in your System Preferences.
Before you start, open the Output pane of Sound preferences (choose Apple menu > System Preferences, click Sound, then click Output).
Choose a sound output device
From the list of sound output devices, select the one you want to use. All sound output devices available to your Mac are listed, including the computer’s internal speakers, devices plugged into your computer’s sound port (), USB speakers, and AirPlay devices.
For any device plugged into the computer’s sound port, choose Headphones.
OS X Yosemite: Adjust your computer’s sound output settings
Thanks for using the Apple Support Communities!
Cheers,
Alex H.

TV & monitor connected via DVI to VGA & DVI cable. Wont display

I have my TV & monitor connected to my mini via DVI(input) to> VGA(output) & DVI(output) splitter cable. I cant get both tv and monitor to work at the same time only one or the other. How can I get this to work?
Note: I dont want a continuous display, I just want one to show the same as the other. If there both plugged in why dont they both work?

The answer to your question would require having a block diagram of the mini's graphics sub-system. If the DAC (digital-to-analog converter) behind the VGA port is just driven from the same output as the TMDS transmitter behind the DVI port, then I agree it would be possible that both could output the same screen simultaneously. But if the VGA and DVI ports are treated as seperate channels all the way back to video memory, then likely one would be prioritized over the other, only one could be active, and they would not be able to output simultaneously.
Another potential problem is that TVs and computer monitors generally want to run at very different formats and they require different signal types to be happy. A TV will want an interlaced output whereas a computer monitor will not. And a TV will want a very low resolution, like 640 x 480, whereas a computer monitor will be happiest at a much higer resolution.
I hope for you that someone else has this working and chimes in with some practical advice. I try to avoid making posts where I have no practical advice to offer and only bad news, but in this case I thought you might want to know about some potential barriers to success. Good luck.

MacMini (2011) problem with Thunderbolt display if 2nd monitor is connected via HDMI/DVI adapter

Hi,
iam running a MacMini (2011) 2.3GHz i5 with Mac OS X 10.7.4 16 GB 1333 MHz DDR3 256 GB Samsung SSD.
If i connect a Thunderbolt display only - all is fine.
But if i connect a 2nd monitor ( Samsung S23A700) via HDMI / DVI adapter (original Apple) the major screen (Thunderbolt Display) sometimes
is going black and immidiately back to normal. It looks like that it happens very often if i scroll down with the Apple Magic Mouse.
Any ideas?
Thanks in advance
Thomas

I have exactly the same problem. MacMini Server i7 (mid 2011) Macmini5.3.16Gb ram.
Mini and Thunderbolt no blink-outs.
Mini and Thunderbolt and Dell 23" connected to HDMI-DVI connector, the Thunderbolt display blinks out when system is under stress as in the Develop module of Lightroom 4.
I thought it was a problem with my Thunderbolt display, and since its on a VESA mount, I didn't really want to haul in in to the Apple Store. I decided to be sure it was the dosplay...
I borrowed a MacbookPro i7 and ran it from a clone of my Mini. No problems aster hours of use. (But with only ONE monitor.) That suggested that there was no problem with the Thunderbolt Display.
I decided to run the Mini with only one display. Again no problems. I plugged in the Second monitor to the HDMI port and within 2 minutes I had my first "Blink-Out".
I ran the rest of the day without the second monitor with no problems.
I conclude the mini will not work reliably with two monitors if one is a Thunderbolt.
I was using two Dell Monitors before I got the Thunderbolt Diskplay (for 3 months) without incident.

Thinkpad Edge S430 - Windows does not detect external display connected via HDMI

On a Thinkpad S430 with HD4000 integrated graphics, an external display connected via a HDMI cable is not detected at all when using Windows. The system is fully updated as of the time of posting this message, both via the Lenovo Update tool as well as Windows update.
The Intel driver version is 8.15.10.2696. It appears that this is the latest version, since it does not offer an update when I try to auto-update it via Device Manager.
NB: I am running Ubuntu 12.04 with kernel 3.4.0 on the same machine, and the external display works perfectly fine with this software configuration.
Hence I think that it's very likely that this is a Windows-specific driver issue.
Would Lenovo happen to have a driver update in the works? Alternatively, I will be thankful for any suggestions about possible resolution of this problem.

MBP 13 Retina unsharp picture/fonts by connection via HDMI?

Hi everybody!
I've connected my Samsung S24B350H display via HDMI to my MacBook Pro 13 Retina.
I'm not happy about what I can see after the connection. All fonts, shadings actually seems to be unsharp.
Before I bought the MacBook, the display quality looks great with a Windows PC (same cable).
Meanwhile I tested 3 different cables and a further display (my tv).
What can I do? Should I try to connect the display via a 'Thunderbolt to HDMI' cable?
(I know that I'll never reach the retina quality on my external display, but there is a better quality possible (e.g. the same display by using a Windows machine).)
Regards
Daniel
Ps. I'm using OS X 10.8.2

Regarding your 'surround sound' issue, look at this discussion:
https://discussions.apple.com/thread/4450049?start=0&tstart=0
I do not have a retina MBP, so start a new discussion regarding your graphics issue. It is simplest to have one issue at a time on these forums. Your interests will then be best served.
Ciao.

No sound on LCD TV when Satellite A200 is connected via HDMI

The problen is: I connect notebook (A200) to LCD TV (Philips) by HDMI. The video is OK, but sound stay on notebook not in LCD TV.
May be the problem is HDMI 1.2 does not support sound and video together? Only 1.3?
Sorry for my English

Sound should work with every HDMI cable as far as I know. Have two of them, one with HDMI 1.3 and another one, which I don't even know, but I guess not the 1.3 standard, as it was pretty cheap.
To enable sound via HDMI you will have to go to control panel - sound. There select the digial output device as standard. Make sure you have closed the media player or any program which has sound output before. Then start player again and sound should now be heard through TV.

How to connett via hdmi and VGA adapter for my Toshibe 3LCD data projector

My HP Pavilion running windos 8.1 can not converse via HDMI A to VGA adapter to Toshibe TLP470Z data projector

Checking the manual for the Toshiba projector, found HERE, it states:
The projector cannot be connected to a computer that does not have
an analog RGB output terminal. For details, refer to the computer
manual.
• You may not be able to connect some computers to the projector.
The model number of your Pavilion PC would be most helpful.

ATV2 - Can I connect via HDMI to TV and connect to outdoor speakers also?

Currently have an airport express on my mac and i just bought Apple TV (2nd Generation). Essentially I would like to connect ATV2 via HDMI to my TV to play movies, see photos, and play music but I would also like to connect ATV2 (perhaps via optical output?) to a receiver or other speaker system to play music outside on my deck.
Is this possible? I was told at the Apple store prior to purchasing that it is possible. Has anyone here accomplished this? Both connect to TV and also to another audio component??

The answer to your question is yes.
I currently have the HDMI running through my receiver to my TV for movies and music in the Home Theater, and the optical output (going thruogh an optical to analog converter) to the Multi-Room input on the receiver. This provides music to three other sets of speakers in the house.
The Multi room input on my Marantz receiver only supports an analog input but with the converter everything works great.

Can not select TV speakers when connected via HDMI

I have a MBP fully updated connected to a Sony TV vis HDMI/miniport. Up until today this configuration was working fine. Suddenly, I can no longer select the HDMI speakers in my audio preferences. They are recognized and appear on the list but when I select them it has no effect. Before today, when the TV was connected the HDMI output would be automatically selected and I could not access the volume control from the menu bar, which is the way I prefer it.
I have restarted with no success in changing this behaviour. If I open/close the lid, the sound goes to the proper settings for about 2s but then the HDMI speakers are de-selected and the built-in speakers are highlighted. I can manually select the TV speakers but the setting has no effect.
However, I *am* getting audio output through the TV but can not control volume from the mac or any app. I slide the volume slider on the menu bar and the audio output does not change. The sound is also playing from the laptop speakers which is highly annoying.

and now there is no audio through the TV at all. TV works fine with other inputs such as PS3. Any help?

AppleTV 2g connected to HDMI to VGA adapter

I connected my AppleTV to my TV via a HDMI to VGA adapter. On power gives no signal and display a message "Out of Range", to connect another device with the same adapter works properly.

OK, thanks. Just one question.
I could get the Kanex ATV pro in Mexico, because the adapter I have now cost me much to get it, and almost not many options.

How can I use my iPod Touch as a remote for iTunes, while connected via USB?

I was wondering if I could use my iPod touch as a remote/iTunes extension while it is connected to my computer via usb.
It would be highly practical to control my music from there, since it is charging right by my side while I'm at my computer.
Remote is not really an option, my computer doesn't have bluetooth or any connectivity. Something over wifi would work, but there's a usb connection right there that's begging to be used.
Thanks

You can't do it via USB. Go to the App store and download/install the Apple Remote app. It can control iTunes on your computer via wifi.
