View Full Version : Stuck with 720p or 1080i

27-04-2010, 11:25 PM
I have just bought a 46" Panasonic Plasma Full HDTV. Connecting it to my up-scaling DVD player the TV displays the movie at 1080p. My PS3 plays movies at 1080p on this TV without any problems. The problem I am having is when I connect my PC to the HDTV. The best resolution I can get is either 720p or 1080i. If I set the nvidia control panel at 1080p (1920x1080 native) the TV screen goes blank. the computer is connected to the TV with an HDMI cable. The graphics card is a GT220 (512mb).

Any help to resolve this problem will be appreciated. :thanks

You need to adjust the refresh rate appropriately. I'm unsure if it's 50 or 60hz, but I think it's one of those two ...

Check your TV manual and it should till you what res. it will display through the PC input.
My Sony Bravia manual dose.

I've checked the manual and it says that the TV should be able to run 1080p through HDMI. I have also checked the refresh rate in the Nvidia control panel and it reads 60Hz. I changed it to 50Hz still didn't work so I tried 24Hz. Now I have a 1080p picture on my Panasonic HDTV.:clap

Thanks for your ideas and help.:banana

I have 1080p on my HDTV but because the refresh rate is only 24Hz the TV flickers when watching video from the computer. There must be a way to have flicker free video. My main problem is that any higher refresh rate just gives me a blank screen on my Panasonic Full HD TV. The manual for the TV says that it supports 1080p 60Hz but I can see no settings that I can change that will make this a reality. I believe that the setting to achieve this must be on my computer because as I have already said I get excellent results from an up-scaling DVD player and from my Play Station 3. :confused:

I hooked up two different PC's to my TV, Both through HDMI, Set the resolution to 1920x1080 and the quality of one was awesome, and the other just went to crap, It was just asking too much of the video chipset, It was drawing half frames and crap, looked absolutely terrible, refresh rate dropped to 30hz.

I forced the settings I wanted and it just fell over.

Hi Metla
I'd be interested in the spec of those computers? Perhaps other posters could do the same together with results.

Get better / a later version of the drivers?

Get better / a later version of the drivers?+1 is the driver you presently have installed, from nvidia or is
it the generic windows7 one? Try installing the latest from nvidia website
and see if that helps.http://www.nvidia.com/object/win7_winvista_64bit_197.45_whql.html

That is the latest driver from nvidia.
197.45_desktop_win7_winvista_64bit_english_whql =
this driver is dated 3/4/10.
So not having the latest driver doesn't seem to be the problem.
