Nvidia ION overscan issues

post #1 of 6
Thread Starter 
Hi guys - Just wondered if anyone had encountered a similar problem with the Nvidia ION based boards. I'm running a Zotac ION-A Mini-ITX board, however there's a fair amount of overscan at my LCD TV's native resolution of 1920x1080. The trick seems to be setting a custom resolution in the Nvidia Control Panel (ala resizing the screen)

I'm fairly surprised by this issue, as my other HTPC, with a ATI 4200 IGP does not suffer overscan (based on ATI's past driver support, it's funny that Nvidia drivers seem to be the cause this time round)

Unfortunately my Hitachi LCD doesn't have any options to manually compensate for overscan/underscan. Although the image appears to OK after resizing, it does seem to be a little oversight on Nvidia's part.

I'm assuming you're using the latest drivers etc?

Are you connecting via HDMI? I had this issue and tried a DVI to HDMI connection which sorted out the issue. This was with a ATI card though.

Hi tedman - Yeah, I'm using the latest drivers. The connection is over HDMI. I suspect this may simply be an isolated issue with Nvidia drivers, as I've found a few sites which mention similar issues.

Check your TV to see if you have it set to 16:9. I know with my 2x LCD TVs I have as computer monitors (one on an actual Ion HTPC in the living room) you need to set it. It isn't necessary an overscan issue but a TV setting. I'll bet if you plugged it into an HDMI input computer monitor it would be perfect. Just saying. See if you can find the setting on your remote to switch it from like 4:3/16:9/stretch/etc and see what happens. I know for a fact that it isn't an Nvidia issue.

Hi Nitro, I've checked through every setting for two LCD TV's I have, and neither appear to offer options for stretching or compensation for overscan.

The following thread on the official nvidia forums outlines users having exactly the same issue. http://forums.nvidia.com/index.php?showtopic=107103

At this point I'm happy just to stick with resizing, as the picture quality doesnt appear to be degraded as a result. An added bonus is that after setting a custom resolution in the Nvidia Control Panel, all applications have it as a default resolution option.

That's awesome you found a solution! I am amazed that your TV doesn't have a size option. They usually always have that for all HDMI inputs, then again, I'm running 2 Samsung TVs. I'm not sure what you are running tho.
