Default Geforce FX 5200 to Sony 51'' HDTV dvi connection problems

When I connect my Geforce FX 5200 (dvi - i output) to my Sony 51'' rear projection HDTV (dvi - d input) the screen remains blank when turned to video 7, which is the input on the back of the TV. I thought maybe I needed a DVI-I to DVI-D input, but i'm told a dual DVI-D cable
will do the trick. I have that, and the screen remains blank. Any suggestions? PLEASE HELP.

Are you using the proper driver that has HDTV resolution modes? Not all nVidia drivers do support HDTV modes only 61.76 and after fully supports this along with the older WOHL 56.72 version.

Does windows recognize the Sony display or not? Is your GF FX 5200 card have a dual DVI out or single and VGA out?

Here is a repeat of another post:

Nvidia's new Forceware drivers cured it all. These drivers add Consumer electronic display support for DVI-based digital displays, such as widescreen plasma screens (CEA/EIA-861B) according to Nvidia's website. There's a nifty little program called NVKeystone I think in the download that allows you to adjust the screen size from corner to corner. I have my entire computer screen visible now. http://www.nvidia.com/object/winxp_2k_61.77.html

I have one DVI out and a VGA. Windows DOES recognize the TV. I'm trying that download now, but the screen still remains blank as of now.

One thing I am not sure of is if your video card can handle 'dualview' which is what is needed to drive two displays either seperately or as spanned across two displays but is a signle desktop. I know that the high end video cards supports this. Have you tried unplugging the VGA and DVI only and see? You might need to lower your resolution and refresh rate as to NOT damage your HDTV eventhough it is DVI, there is a chance that the tmings and such will not be compatible.

First post here, I have a Sony 42" Wega (offhand, I don't have the exact model name) -- this is what I have gathered so far :

GeForce3 and GeForceFX 5200 (tried both cards) :
- using HDMI -> DVI cable
- PC boots with analog display (VGA), then flips over to DVI
- 1280x720 resolution (720i, I believe)

Now, here's what I did to fix my blank screen issue :

you'll need the analog display plugged in, or a copy of VNC installed, since after you flip the display to HDTV, you'll need a way to change a setting -- and you can't do it blind

I had to lower my display from 1080i to 720i -- which is under nView properties, then going to Device Adjustments, and Advanced, and you'll also have the option to underscan the desktop so it fits nicely here too. -- This is stupid on nVidia's part, since you can only access this setting AFTER you've enabled that display. The GeForce3 doesn't have DualView so I had to use VNC to change to 720i.

But, my problem is, that the color red is gone. Display is sharp and crisp, but it's as if the red pin went bad -- which is impossible since it's a digital signal, not a VGA cable (as I understand it)

*First Post Alert*

I just picked up a 50" Sony Grand Wega RPLCD from Costco (KF50WE620) for around $2500. The only reason I got this model was because it had a DVI port and I just assumed it could be hooked up easily to my PC. Boy was I ever wrong...

Anyway, I too have an Nvidia GeForce 5200 graphics card and I went through all the steps in the Sticky thread and am now able to get "some" display on my TV but it only shows about 10% of my desktop blown way up!

Anyone ever have this problem and know what the best settings are? Also, should I be using the "Clone" mode or the "DualView" mode or something else? Can I have my TV monitor set at a certain resolution and my PC Monitor set at something else or do they both have to be the same? Has anyone figured out what the best resolution really is for these Sony's (I tried one of the suggestions in another thread but it didn't work)?

Oh and lastly, can someone explain what "1080i" and "720i" really means? *confused*

Btw, this forum is great and I spent about 6 hours on here yesterday just reading through all the great info! Thanks a million!

Been using ATI 9600xt for a couple of years with no problem hooked up to a Sony 46 inch. Important thing to remember is to back your refresh down to 60hz (thanks RSawdey for that hint). Initially I had trouble with the Sony recognizing the DVI port on my TV. I had to use the hot keys (with ATI) and toggle between displays until everything worked. ATI also had the option to force 720p display vs 1080i so I kept it at 720 for a wonderful picture. I realize this doesn't help those of you with nVidia cards but I have one question - do you also have an S-video out on your nvidia card? If so, try running an s-video cable to your tv and see if you get a picture on a different input (Vid1 or Vid3 on Sony).

SVideo is a 480i signal, horrible for PC use.

You need to output 1280 x 720 PROGRESSIVE at 60 Hz, it's the native res for your Sony LCD RPTV.

DVI is similar to a digital version of VGA... it's still got three seperate channels for RGB, even though they're digital. You could have a bad cable or connector (look for bent pins).

Thanks for the tips. I will try those setting tonight. I don't think there is a problem with the cables because they are all brand new (never know though).

Is there anyone that can help me figure this out? I finally got a picture to come up using the 480i mode but it is huge and it only shows like the center of the desktop. Also, it's weird because what shows up on my regular monitor doesn't come up on the TV. I used the NVidia driver (the new forceware) and went through the "TV Wizard" thing to tell it I have a TV connected. I have it currently set to Dual View (MONITOR - TV and not TV - MONITOR). Does anyone have any advice?

Please help me...

Change your resolution to 1280 x 720

OP doesn't say, but I think his 51" is a CRT based RPTV... meaning his native res is 1080i and best desktop res would be 848 x 480p.

I have tried everything and 720x480 seems to be the only resolution that will work. I've tried a custom resolution and it just shows fuzzy lines.

I just thought of something, maybe the 1280x720 resolution I tried was "interlaced" or "progressive" and it should be the other. Anyone know if the Forceware drivers will let you choose which type of display you want (interlaced or progressive)?

Thanks.
