HDMI to TV on Windows 7 blurry and edges cut off

post #1 of 13
Thread Starter 
While running Windows 7 or Windows 8 Developer Preview connected via HDMI to my TV, the display looks blurry with less readable text and does not fill the screen to its fullest. My TV supports 1080i but I chose to use 720p (1280x720) for better video playback.

I have tried the latest ATI drivers to no avail, I do not have this issue while running Ubuntu 11.10, or while connected to my PC monitor (1920x1200).

Specs:
ATI HD 5730M, Core i7-720QM
Sharp Aquos 32" LCD 1080i (1366x768)

you should download the catalyst version that is available on ur laptop manufacturers site. I had the latest drivers and wasnt able to adjust my screen size. then i went on the acer site and i got the VGA driver ( old version of catalyst) and now i can adjust the screen size so nothing gets cut off when plugging it to my TV. im guessing that ur problem will be solved by doing this for your laptop.
you shouldnt but it to 720p because its definitely gonna be blurry. there should be a TV resolution setting in CCC and choose 1080i. at 1080i it should look perfect.

My TV supports 720p, but thanks, I'll give CCC a try and let you know how it goes.

Find out what the native resolution of the TV is. My 720p plasma actually has a native resoltuion of 1024 x 768, but that might help. Depending on the model of the TV, changing the input mode(name) of an HDMI connection to PC might help too.

Try 1366x768.

Also some TV's have one of the HDMI ports specifically optimized for PC use, look in to trying the different ports at 1366x768.

You should be able to do 1920x1080 as well and might have to look in to the overscan/underscan setting.

Hard setting to get to through CCC...

My TV's native resolution is 1366x768 and supports up to 1080i, but I cannot choose that resolution for my TV in Windows or Ubuntu and it assumes 1920x1080 is recommended but is much too blurry.

After doing some research it seems to be an Over(Under)scanning issue and can be fixed either through CCC or through a registry hack; but I think I'll use CCC regardless of how I feel towards this software... mad.gif

There currently is no CCC support for Windows 8 Develop Preview so I will either be reformatting today back to Windows 7 or using an external to test your theories.

I just re-installed Windows 7 with CCC and I fixed the black bars using the overscanning tool, but I can only change the real resolution through Windows. Under Desktop Management in CCC the TV is recognized as 1080i, but assumes the resolution is 1920x1080, and there is no option for 1366x768 (my TV's actual resolution), and the "Add" option only goes as low as 1440 pixels... I guess the EDID must be screwed up.

However, luckily my laptop display also uses 1366x768, therefore, can I use the "Duplicate Displays" option under Windows to achieve the correct resolution?

Also, when switching from Basic to HDTV, why does everything look dark-greenish?

Does your TV have a dvi port? I had the same problem but when i used a hdmi to dvi adapter it worked flawlessly.

Unfortunately no, ohno-smiley.gif I do have the HDMI-DVI adapter, and have tried it on my other TV, but even that didn't work.
