Getting HDMI output on Windows 7

Hi there,

I'm having trouble getting my PC to output to HDMI using 32 Bit Windows 7.

When connected via HDMI the screen shows the POST/BIOS however the sides are cut off. Then it shows the 'starting windows' screen but after this it cuts off and shows 'no signal'.

I have a Gigabyte GA-EG45M-DS2H motherboard with an Intel G45/G43 Express Chipset and all of the drivers are up to date.

I spoke to someone from Intel who looked into the issue further and thought that the problem was that the driver wasn't picking up the digital part of the TV as it wasn't reading the EDID properly. He couldn't however offer a solution.

Here is what the Intel Graphics Properties Diagnostic gives:

I really hope that someone can help, it's so frustrating!

Let me know if you need any more information.

Thanks

Just tried that but unfortunately no luck

There seems to be a lot of stuff on other message boards to do with EDID issues but they seem to be limited to issues with Nvidia.

OK, it will boot into safe mode using HDMI at 1024x768 fine but as soon as I put it up to 1280x1024 it displays 'no signal' again. Seems to be definitely a problem with the resolutions.

Any help would be much appreciated!!

You might try going into the settings for the monitor itself and look for something related to HDMI functionality.

If you are successful with it at 1024x768 you might want to use that setting then go to the monitor properties and see what other resolutions it shows available. I would try whatever resolution you think you could live with for the moment if one comes up that stays stable.

I would then go and do a Microsoft Update and be sure you include drivers other than Microsoft so that if your TV/Monitor has drivers out there it will pick them up as well as your video card.

I have a Vizio 37" 1080 HDTV that makes you use the VGA input for PC video so I use a VGA to DVI adapter to do this but it does a full 1920x1200 screen w/o issue, the HDMi does feed the audio portion or I can opt to use the Toslink fiber connection from my sound card which I run trough my digital amp.

There are no settings on the television itself regarding HDMI.

It won't boot into any resolution in normal mode, only in safe mode so I'm assuming it has to be to do with something it's loading up in normal mode. As it only offers me three resolutions in safe mode there's not much else I can try there.

The guy at Intel seemed pretty certain it was to do with the digital portion of the EDID not being read and this seems possible looking at the information above as the HD resolutions are shown as timings supported.

Everything is fine up until windows kicks in and then the signal cuts out which suggests it's something on the computer rather than the screen as far as I can tell.

When you boot into Safe Mode what is the signal it reports from your TV, is it 59 or 60 Hz? I'm not familiar with your TV but if anything like my Vizio there are resolution setting in the menu which has nothing to do with HDMI just with the setting when used other than a TV.
You may have to force your video to keep the signal as DEFAULT then it should boot into Normal Mode.

My TV is an LG 22LS4R which unfortunately has a very limited settings menu.

Windows XP used to recognise the monitor and its model number but Windows 7 seems to just recognise it as a Generic PnP Monitor.

How do I know what signal it is reporting when in safe mode?

And how do I get it to keep the signal as default?

Right mouse button click on your desktop brings up a screen which Screen Resolution is one of the choices, pick that. Once that opens choose Advanced Settings and when that opens you will see a screen with tabs and choose the Monitor tab. You will then see the screen refresh rate, if it has only one choice you can't do anything about it except tick of the hide modes the monitor can't display. If it has 59 Hertz and 60 Hertz chose the correct one for your monitor (check you manual) then hit Apply and OK and reboot your PC.
