I use an hdtv for my primary display and to get rid of overscan I use a custom res of 1240x700. On my ati 1900 this works perfectly with the aid of powerstrip with the 8800 powerstrip does not work.

I added 1240x700 to custom resolutions in the nvidia control panal and when it switches to it that res the display is really screwed up. My tv says its in 800x600 mode and I have no clue on how to fix this. I messed with the advanced timings for 6 hours last night and could not get a 1:1 pixle mapping and 1240x700 to work over vga(tv has vga in) or dvi. I used the overscan compensation tool and it caused the image to scale (major loss in clarity) and the reg hack for the older control panel all with the same results. I really want to keep this card because its just so fast however I can not spend $550.00 for these results. I know powerstrip might support the 8800 series later but it seems for now I am SOL. Anyone have any suggestions ? I am desparate here !

Tv is a Samsung 720p kirk model.

You are SOL.

Custom timings are/have been broken in Nvidia's drivers...over 7 months now.

This topic's been covered a lot already.

Sit back and get comfortable...you're in for a long wait.

Some users have reported success with this issue by using the latest drivers from guru3d.com

good luck

Tried the driver and still no luck. Good thing I have 30 days to return it ! Sad though, they lose another customer over such a simple issue. Guess its a 2900xt or wait to see if it gets fixed. I have always had issues with Nvidia cards.

I am using the 96.94 driver for my 8800GTS, I downloaded it from a gamer web site. It does have overscan adjustment, and seems to work as well as the current 97.94 from what I can see. My future plans include a 1080p display with 1:1 mapping, but meanwhile this works well with my 720p plasma.

I am using the 160.03 for vista 32bit and the "Desktop Resize" now works in the control panel on my 8800gtx, whats weird to me is that the computer still calls it 1920x1080 instead of a new resolution but it still works.

This is on a mits 65-732 1080p dlp through DVI

Do you use your machine for gaming?

Overscan adjustments do work with the 96.xx drivers, but I found them to be completely unstable when gaming.

I was under the impression that that's the way overscan compensation should work.

I use mine for gaming as well and not only do the 160.03 drivers work well for overscan compensation and HTPC purposes, but they seem very solid for both OGL and DX games.

Best 8800 Vista driver so far, imho.

does pure video hd work with the 8800 now or is it only for the 8500 and 8600 cards?

I like my 8800gts but am getting kinda tired of the jerky mpeg2 playback.

Overscan is lame isnt it ? I have a 1280x720 set and 1240x700 is viewable. Well I found a comprimise. Using overscan adjustment via the drivers causes my set to scale and thats a no no and from what I have read and tried I have to say that the implementation of overscan compensation just sux. I think I speak for everyone when I say we want a 1:1 pixel mapping on hdtv. Just display the res we tell you to display and shut up !

I was able to find out what was going on. When making a custom res of 1240x700 the nv card was sending the wrong timings to the TV and kicking it in to 800x600 mode and windows was trying to display 1240x700 in an 800x600 window. Needless to say it was screwed up looking. I raised the 700 in increments of 2 until I hit 716 and got a stable picture with only 16 lines of vertical overscan which is acceptable. If you look at all the windows resolutions the lowest vertical res before you hit 800x600 is 720, the next higher is 768 as in 1024x768. It appears when the vertical res drops below 716 the card sends timing for 800x600 because that is the next lowest vertical res.. Basically what you can't do with the nvidia custom res app is make a resolution in a resolution like you can with the powerstrip app that I used on the 1900 since it does not work with the 8800 series yet. With powerstrip you can send 1280x720 timings and have it only draw 1240x700 inside of that. If powerstrip support happens this will no longer be an issue. I did at least find an acceptable compromise.

IF anyone is having trouble with custom resolutions you might want to try what I did to get acceptable results. You may be able to find a fair middle ground.

This is strictly an HTPC, I haven't tried any games on it. I'm sure there are reasons for the updates made after this version, but I'm hopng this will work out until nvidia comes up with a new version with functional overscan adjustment.

If this computer is strictly a HTPC and not going to be used for games you should return your card and get a 8500/8600 series.

Cheaper, less power consumption, hardware accleration works and plays nice with NVIDIAs latest drivers. (From what I've seen the 8800 series don't.)

Its an htpc hidden behind a wall with wireless keyboard and mouse and a usb IR device to power on. Its used for gaming on my home theater.

Home theater (Playing movies - particularly HD and Blu-Ray) places different demands on a system than gaming (Playing Video games). Gaming uses more memory and CPU typically, to be able handle motion and 3-D, so a higher end video board (8800 GTX 640)with more onboard memory, plus typically a faster CPU and more RAM are found in a mostly gaming machine.

Playing a Blu-ray movie may be more suited to an 8600 GT 256, due to better handling of H.264 in the 8600 series http://www.anandtech.com/video/showdoc.aspx?i=2977 1gig of average speed RAM with an overclocked E4300 may work well for home theater.

However, if you are going for both functions, you may want to go for the more resource heavy gaming rig, which will also functiom well when playing blu-ray movies, albeit for more money.
