GWIII, 6800GT & Powerstrip - please help

Hello,


To start, I've spent days and days searching and reading the relevant FAQ's, threads and how-To’s here and on htpcnews.com before asking for help. The ultimate goal here is to convert the PC I just built into an HTPC. But first I'm just trying to get the PC connected to the GWIII (KF-60WE610) and try some DVD's (using the new Nvidia codec, Zoom Player and ffdShow), games, etc. to evaluate the PQ. Having carefully followed the recommended processes and settings for connecting the PC to my GWIII via DVI, I get massive over scan on the desktop. Here are the PC specs:


P4 3.4Ghz 800Mhz Hyper threading Northwood

Asus P4C800-E Deluxe Motherboard (latest BIOS)

480W Entec True Power PSU

2Gb Corsair Twinx 3200XL

BFG Tech 6800GT OC 256Mb AGP video

WD Raptor 75Gb SATA drive

Creative EMU 1212 Audio card

Plextor PX-712A DVD RW


Windows XP SP1 (Ihave SP2 if necessary)

Nvidia 61.7 drivers

Current resolution 1280x1024 @75Hz 32bit


I've attempted to follow several of the custom timings listed here

http://www.avsforum.com/avs-vb/showthread.php?threadid=362324&highlight=GWIII+timings


under both 720P and 1080i by pasting them into Powerstrip’s user defined custom resolutions. Unfortunately, it seems no matter what rez and timings are used the over scan makes the desktop unusable.


Any ideas as to what I'm missing or doing wrong:confused: Sorry if I’ve missed something obvious!


Thank you,


FG

Powerstrip will not function with current NVidia drivers. Use the built in custom resolutions feature. I have not worked with the 6800GT and remain unsure if NVidia was able to get custom resolution support onto the card.


Currently, you need a NVidia card with an external DVI TMDS chip, usually made by Silicon Image, to get it to work right. Im running with a 5900XT with no problems.

Hi vidkidd,


Thanks for the clarification! Not the answer I was hoping for, but at least now I know. Kind of sucks to have a $400 video card that can’t use Pstrip...:mad:


My Nvidia properties do have the advanced timings option, which I just tried on the CRT and it seems to function as expected. Guess I'll try it on the GWIII next.


Best,


FG

Hi Vidkidd. What mfgr. and model of 5900XT card do you have? Does it have single or dual DVI and what specs define the existence of external DVI TMDS chips in these cards? Thanks!

How is the PC connected to the display?


You will need at least the 66.81 drivers.

Hi Vern,


The PC is connected via the DVI out on the 6800GT to the DVI in on the GWIII. DVI cable is a 12' Monster. 66.81 drivers? I thought the 61.77 were the latest on the Nvidia site? Where does one find the dirvers you mention?


Footnote: after again connecting the PC to the GWIII, Windows recognized the display as digital, and removed the advanced timing optoin found in the Nvidia panel.

Hi Family Guy. Were you able to correct the over/under scan issues once Windows recognized the GWIII as a digital display? I've got the 50" GWIII and am trying to identify a suitable video card to drive the display. My understanding is that you need access to the advanced timing options which are available from a video card that has an externally driven TMDS DVI connector. Thanks!

Hi Tiarella,


No, I was not able to resolve the overscan. Vidkidd has stated that Powerstrip will not work with the Nvidia 6800GT and 61.77 drivers, which is my setup. That only leaves the custom resoulution options in the Nvidia panel, which were disabled once I changed from the CRT to the GWIII display :-(


This is confusing, however, as the Nvidia 6800 series cards are highly regarded as HTPC cards on this forum. Yet if they cannot conntct via Powerstrip, which seems to be the go-to custom resolution software, and don't work well with the GWIII, then why are the cards so highly regarded?


Confused...

Here's the official Nvidia FAQ on this subject, along with a link to the 66.81 drivers Vern mentioned

Im using the 5900XT from BFG. NVidia locked Powerstrip out of the DVI ports a while back. I think around revision 55.xx, perhaps earlier.


Im using an older driver revision of 66.12. SOme of the interim drivers drivers changed something that has prevented me to get a clean 1:1 on all my custom resolutions. Ive been too buzy at work to chase up NVidia or try out the new drivers. I have a "clean edge to edge image" that I dont was to mess up at this point.

I am using an older model of the nVidia card, gf4 Ti 4400, and with the new 66.81 I am able to easily get 1177x662 with no overscan and the card recognized the display as a Sony TV....

I guess the difference is that I 'm running 1328x752 with a 1:1 image. The more resolution I can get out of my set, the better.
