Geforce 6800 - Forceware 66.00  

Do either of these take care of the EDID bug nvidia has that dosent enable their cards to do 1368x768 res on an hs20 projector?

I had a little bit different problem with the EDID bug, but these drivers fixed my issues. They have some new options that let you set the output signal to 480p, 720p, or 1080i. I just set mine to 720p and selected that I wanted to underscan through the DVI. I know have a 1:1 pixel map with no overscan.

I tried these drivers. I set the output to 720p and selected the underscan option. This causes the resolution to be changed to 1088X612 which does NOT give me 1:1 pixel mapping.

At least there isnt a need for keystone to see the whole screen. Its a good start.

where is the underscan option located in the drivers? what tab? Also are you coming out DVI to the HDTV? or using an adapter?

I'm going straight from the DVI out of my video card into the DVI input on the TV.

Under the display properties you need to go to the nView Display Settings screen. Click on Device Settings and click on Treat Digital Display as HDTV.

Then select the kind of output you want through the Select TV format. When you click on Apply you will get this window.

If everything works out okay you should have a 1:1 pixel map of an underscanned resolution like this.

brogers,

Thanks for the post. This worked on my Samsung DLP with 65.xx drivers, but I still like overscan better for the movies. Just don't trust the "wrapped resolutions". Did you notice any issues with no overscan mode while watching moves?

By the way, my wife would kill me if I had all this gear in our TV room. You must have trained your wife well. I had to hide all of it in the closet and run all audio/video/power wires through walls.

I'm currently use my DVD player for watching movies. I think I may eventually start ripping all my movies to a large HD as ISO images. Then I could just mount them as needed. I just haven't made it that far yet.

My wife is sort of a nerd like myself. We mainly surf the web and play games on the computer more then anything else. The only thing really sticking out is the computer and UPS(backup battery). I will eventually add to the furniture in the living room to conceal more components. The keyboard on top is just temporary. I'm completely wireless using Microsoft's Bluetooth keyboard and mouse. :)

When you say 1:1 pixel mapping you mean the windows resolution is set to 1280x720 and it displays the full resolution on the screen? Bc that isnt what is happening. The resolution is lowered to compensate for the overscan. If you go to the resolution settings it will be like 1177x662. Thats what mine is at.

I dont think its a wrapped resolution like keystone. Its just a resolution lower than the native display setting to compensate for the overscan

So how does the new Forceware drivers treat a 4:3 HDTV set? I'm primarily focused on how video will look on my 32" Sanyo HDTV using Meedio/ZP. I don't want the video to be stretched or squished. I'm currently using Keystone with the NVIDIA 61.77 drivers @ 1280x720 & everything appears to be OK with the exception of the following:

- Text is not as clear as I expected it to be. Large fonts are fine, but smaller fonts are probably just as clear as they were on my 27" SD Philips/Magnavox TV.
- Mouse lagging due to Keystone (not really a problem since this is supposed to be a basic media playing HDTV)
- DVDs are stretched vertically using the default Meedio player. Think this is a Meedio problem.
- DivX/Xvid videos tend to lurch along ever so noticeably. It might be a natural side-effect of these codecs, but I'm thinking Keystone my be the culprit.

I definitely have to do more testing on my end, but was wondering if anyone has tried these Forceware drivers on a 4:3 HDTV.

Thanks,
jawgee

Brogers - Thanks :) :) :) for the detailed info... exactly what I was looking for... well off to do this to my PC this weekend ... tried Keystone and it worked OK but wasn't optimal mouse was jumpy and screen sometime had artifacts.

Looking forward. hope my old Ti200 will allow this option with the new drivers. the only thing I find is that messing with the flat panel settings. one wrong click and boom your get nothing on the TV screen and are flying blind. I then have to haul downstairs a CRT to hook up so I can see the screen to reset back the settings :(

As far as training wife ... hmmm better to find a wife who is just as techy as you are then you may have to keep her from putting too much stuff in the tv room ;) I think in a few years, the PC will be standard item right next to the TV. Check my Galery pics for a look at how much stuff I have next to the HDTV.

Try them anyway its a quick try, keystone is the cuplrit with the choppy video, bc when i used keystone all my videos were too annoying to actually watch with keystone. Keystone is just a really bad solution, but if thats all I had a choice of then I could deal with it, just annoying getting a 3000 dollar tv or so and having to "deal with it".

Thanks for the reply, dinkme. I can't wait to try these drivers out, but regular life seems to always get in the way. :( Anyway, does this contain the entire NVIDIA driver set, or do I just install them on top of my NVIDIA 61.77 drivers?

Thanks,
jawgee

There is no installer for the 66.00 drivers. You have to extract the package you download and then go to the device manager, right click your card click update drivers and point it to the directory to where the drivers are, it will install them and have you restart. If you have problems with it or it doesnt fix our problem just go to the device manager and roll back the drivers to the 61.77 These are beta, so they will have bugs, but I havent had them crash on me yet. Been using for about two days straight. They seem stable for me, but I can't say how good they will work for you, but its worth a shot to make things better. I'm using a 6800 GT on an athlon 64 k8t800 chipset mobo Aopen AK86-L to be exact.

I'm very curious as to why some have the "choppy mouse" or "choppy video" problems using the NVKeystone. I'm using a 6800GT to an HS20 via HDMI and it works flawlessly and looks great (so far anyway). Could it be due to hardware (I'm running a 3.0GHz P4 with 1GB dual channel RAM)?

So far the NVKeystone is the only solution to my "EDID bug" problems which keeps me from using DVI ---> DVI. If I start having problems with the NVKeystone I'll be right back to square one...

Yes mnn1265, it must be the hardware.
I have a machine about 4 gen back (P4 2.4B, 512 PC2100, GF4 Ti4200) and I get choppy also. With your kind of machine, you probably don't even notice when FFDshow is open ;-).

No, your right. Well, unless I futz with the resize, sharpen and denoise settings where I can easily grind it to a halt... :)

unless keystone has problems with athlon 64s, I think i got enough horsepower. Running an athlon 64 2800+ 6800GT and 1 gig of corsair low latency. Using a monster dvi-hdmi cable.

Using Keystone correction and using Underscan are two completely different things.... Underscan is just the same thing ATI/Powerstrip users have been using for a long time - a resolution within a resolution. The actual raster sent to the display is at the full HD resolution, be it 1080i or 720p, but the Active Video is set to a lower number, such as 1600x900 for 1080i, or 1177x672 for 720p. Keystone, however, uses the cards scaler to actually scale the video to either a non-rectangular (for keystone correction) or rectabgular "window" which can be used to achieve underscan. The problems you notice, choppy video and mouse stutters, are from the increased computational time it takes to do this scaling.
In my case, using the YPbPr outputs of my 5950U with the 6600 driver, this driver is VERY close to Nirvana... the advanced settings tab has allsorts of tweaks which allow you to do the micro-settings that powerstrip gives you... nVidia users will NOT be using powerstrip very much longer !! And the custom resolution tab (almost) allows one to set up any resolution for the underscan.... I say "almost" because there seems to be some bugs here... or a lack of adequate documentation :) I got the driver to accept 1776x1000 (a popular ATI custom 1080i sub-rez) but no other rez I tried would take.... anyone have luck with any other custom rez's????

:cool:

havent tried custom res but just picking HDTV and fix underscan to see entiredesktop like shown above worked great. loose about 1/2 of the scroll bar on the right but its basically plug and play DVI out thru a cable to HDMI into a JVD D-ILA Lcos screen. working great !!! thanks for the heads up on the 66.00 leak.

no powerstrip messing around. just using FFSHOW to clean up my DIVX videos and all is cool. (cool bits works great on the leaked drivers as well) OC my old ti200 back to ti500 speed. the card has alway run since almost day one at ti500 speeds...

guys, :)

i'm interested in this card for my video editing.

but most of the preview/review sites used earlier driver to test 6800's built in programmable video chip. which turn out poor result.

i'm wondering, has new driver improved in this area? in term of speed and cpu usage, especially video encoding.

Hey All,

The drivers are "functional" but are far too "buggy" to create extended 720P resolutions with true 1:1 image output on fixed pixel devices. Im still using the 61.xx drivers until a better revision hits as I'm unable to get a clean image on my GWIII XBR with these drivers.

Hopefully the next leaked revision will provide better support. Steps in the right direction but still too early....

Thx,

I cant get interlaced 1080i via DVI to my xbr910 to work properly on any drivers past 61.77. All the new drivers seem to break my interlaced resolutions and i get massive picture jitter. I guess I'll keep waiting. I would love to be able to correct the over scan I get with 61.77 without keystone.:(

why buggy? seem to work perfect for me.

Iam quite happy with the 66.00 drivers as ALL I want is 720P to my JVC L-IDA TV. so with the DVI to HDMI cable and these drivers I can watch and surf the net. True 1080i doesnt work but my native resolution on the TV is 720p anyway. Works fine for Internet Explorer and also playing DIVX movies via Media Player and FFShow filtering.

Thanks for that confirmation of the cause of the "jitters." I guess using the NVKeystone is less than ideal (much less) because i'm chewing-up a good amount of CPU just scaling my display to fit on the screen... CPU time that could be used for more post-processing via ffdshow. I've actually noticed that I can't do as much with ffdshow using the NVKeystone but I'm fairly pleased with the picture nonetheless.

If there's a possibility that would work for me (using DVI ----> HDMI) I could lose the NVKeystone... well, until NVidia fixes the EDID bug so I can use DVI ----> DVI. I don't think that fix is in the current beta 66.00 drivers.

For an average "out of the box" experience.... And for users who only want a clean 1280x720.... They are great. For anyone who wants to push the envelope of what they can do... They just don't stand up to what the other Beta's or released drivers can handle. When entering custom resolutions, it doesn't remember the settings entered and display the currently active numbers.

The Forcweware team is making great strides.... Just the custom resolution support is a bit whacked this release...
