HDMI resolution problem

Steev · 26 May 2012

Hi everyone!
So I bought a new computer yesterday and went HDMI into my HDTV, and the toolbar and the icons (lined up on the left side) weren't fully visible, as in the resolution was a little too big.....does that make sense? lol
I bumped the resolution down a little and my TV went black with a 'Not Supported' bubble floating around and its now stuck there. I can't get out of it with Esc, or Ctrl Alt Del, nothing knocks it loose.
I'm going VGA for now, and it does say that I'm maxed out resolution 1080....hmmm

Any ideas?

Thanks a ton!

Hi and welcome to severn forums

Have seen this many times. LG told me this was due to overscan, and were unable to offer a solution with their own TVs.

I have found a workaround though - many cards come with a screen "resize" function that that allows you to fit the top/bottom and sides to the screen. I use mostly nVidia, but I had one customer that had an ATI and it had a similar feature.

Different TVs handle the resolutions differently. You can try different refresh rates. Your TV will complain if you go out of range, in which case waiting 20 seconds the setting usually reverts if you don't accept the settings.

Most TV manuals also have a glossary that tells you what resolutions and modes they support. If you have not already done so, it might be worthwhile consulting the manual.

Hi Tanya! Thx for the response :)

So, I'm a little further now.....I got under the hood and fooled with things and tweaked things and I'm now have it going HDMI (which was the goal)....BUT it doesn't look HD at all, ya know? I assumed it would look super crisp and clear and awesome and it doesn't, but it should, right? lol
I went through all the calibration and adjusting stuff, but the colors look a little weird, and the text looks rough, etc......it just doesn't HD at all

Thanks!

Have you checked your windows performance settings?

Also, are you using clear type text?

Can you tell me what brand and model your HDTV is?

You probably know all this...

Remember, for video files, the quality depends on the quality of the input source, not so much the quality of your TV and HDMI cable.

For Terrestrial TV (Satellite or Antenna), it depends on the quality of your signal, and of course, older TV shows were not in HD.

Is your HDMI cable a good cable, HDMI v1.4, or at least 1.3b? Some of the older cables could only handle a bandwidth of 2.4mbps, which is not HD. A cable of 10.2 mbps bandwidth is recommended.

There are 5 types of HDMI cables: standard, high-speed, standard with ethernet, high-speed with ethernet, and standard automotive. Standard supports up to 1080i, whereas high-speed supports 1080p and beyond, in addition to (but not limited to) deep color and 3D. HDMI cables don't have a spec associated with them - that's reserved for hardware components only, like TVs and receivers.

On your TV, look for 1:1 pixel mapping. That's the best way to configure your TV for computer use. Your TV manual should also explain what resolutions are supported, so you can prevent this from happening again in the future. If you can't see everything, there's an overscan issue - which sometimes can be fixed by the video driver software. If you receive a black screen, you can sometimes boot into safe mode and reset the resolution and then reboot.

Also, please fill out your system specs. Click on the link in my signature to do that.

Right after your mother board post press F8. This will bring up the windows boot options. You will see a 600x800 resolution boot option (not sure if that is what exactly what it says). Boot using that then select your resolution.
