Poor image from PC using Plasma monitor

acdecal asked
Last Modified: 2013-11-08
We have a 42" Hatachi P42T501 1080p plasma screen that we would like to use as a monitor.  The PC we are connecting from is a Windows XP with a Nvidia Ge Force 7600 GS card (512MB DDR2).  We are using the computer for Autocad applications.  We have connected the screen using a DVI to HDMI cable.  Image flickers and is not clear.  We have played with different resolutions and settings but we can't get a clear image.  Any suggestions?  Do we need a different graphics card?

Do you have your computer resolution and refresh rate set to the native reslotion and refresh rate of the monitor?
How long is the cable? Is it a high quality cable?


We have set the card resolution to 1080i and the refresh rate can only be set to 60 hz.  We tried 740p and it looks somewhat better, not the best, but everything is twice as large.   We are using a 6 ft. high quality cable.  
Try setting the resolution to the displays max 1024x1080. You may need a program like Powerstrip(http://www.entechtaiwan.com/util/ps.shtm) for a custom resolution. In my experience a low resolution like 1024x1080 on a 42" display just doesn't look good. I would return it and get a display that supports at least 1920x1080. Also if you want Autocad to run better you may want to look at replacing the 7600gs with a Quadro card.


Thanks jamietoner,  can you suggest a certain Quadro model? Do you think between the new card and tweaking the resolution with Powerstrip we can get an acceptable image on the Hitachi?
The new card's not really going to help with the display just make autocad perform better. Running the display at its max res should make it look better. For a good mid-range Quadro card i would suggest an FX1500 or FX1700.


Does a card that provides 1080p versus 1080i make a difference?
Most cards will support higher resolutions than 1080p(true 1080p has a resolution of 1920x1080) the fx1500 and 1700 both support a max resolution of 3840x2400. The 7600 gs has a max of 2560 x 1600.


Thanks, one more thing: Where do I find the timing information for the Hitachi monitor?
