Hdmi Trouble

[raro]

I bought me this expensive (1200 Baht!!) GeForce 9500 GT card and want to connect my comp to a Samsung Full HD 1080p TV set via HDMI cable. I used the very same TV before with a standard VGA cable and no problems whatsoever. Now I thought about a general computer upgrade (processors and all...) and busted....the picture is not clear whatsoever, I adjusted already the overscan but the picture is still a mess. Played then around with different resolutions until I found one that the TV cannot display and safe mode cannot remove. Right now re-installing windows. Arrgghhhh....

//edit: no beer at home either....

Many times a "full HD" or "HD ready" LCD TV will not display anything higher than 1024x768 (or perhaps 1280x768) resolution over HDMI to the PC.

I have the same problem with my LCD TV. It is a 1366x768 LCD, but only does 1280x768 over HDMI, making the image unclear and frankly very bad.

Using a normal PC15 cable of good quality allows me full resolution and good picture.

Maybe the manual has information of supported PC resolutions?

ok....back to the VGA cable, I cannot display anything better than 1280 x 768. With that old computer I had full blown 1920 x 1080 on VGA. Now win7 has this function with screen sharpening or something like that and then it moves to 1920 x 1080 but as soon as I reboot the comp, it says "mode not supported". Even worse, even if you reboot and do the old F8 routine and reboot in standard VGA, my TV refuses to display anything.

The old VGA card does not fit into my new motherboard either, must be some older standard. grrrrrrrrrrrrrrr:annoyed:

1080P is not something less than full HD, how long is your cable? there may be signal loss and the cable may be the culprit or the card could be faulty. I have a pc connected to my tv but with a very short cable, it works perfectly from the moment it was turned on windows recognized the screen resolution and that was it. GPU is a 4350 not that there should be anything wrong with the model card you have.

1200 baht is hardly expensive for a GPU, some are over 30,000

strange. nice card and win 7 has nothing to do with this problem.

try to get a friend to look at it or a remote friend to look at it with a remote control program.

edit: if you havent tried: get the latest driver from NVIDIA website and install that.

[raro]

Latest Driver: Done

Friends: remote would be ok, otherwise they would just empty my fridge.

Short cable: Yes, same cable as before that created no problems under winXP and his 7 year old Pentium III and an even cheaper graphic card

1200 Baht for a graphic card: guess my late-night irony didn't work that well......but I'm not willing to pay more than that, certainly not 30,000 - doubt those cards can display this webpage any better than the cheap ones...other than that I don't o much with computers...

I tried again with the HDMI cable, for some strange reason the picture has become better but still not good.

I have direct HDMI output from Intel chipset on my laptop and display on Samsung 1080 is reading 1440x900 but suspect that is due to my widescreen dual display 1366x768 and trying to fit it all on the TV. The picture looks good.

I had problems when I first connected my Samsung via hdmi.

The first cable I tried did not work at all,

the second does, but is sensitive, and I need to make sure the plug is securely in place.

You need to set/rename the HDMI source input as "PC" then it will enable you to use the native 1920x1080 resolution properly and you will have a pixel perfect image (assuming you've set the resolution to 1920x1080 on your computer).

tried it but didn't work.

Is it possible to try the computer with a different TV?

In the early days of HDMI there were stories of incompatibilites,

where the two boxes, TV and computer in your case, could not negotiate the "handshake"

successfully to display the picture.
