Just got my eVGA 9800 GTX+ and I am using it on an ASUS A8N SLI-DELUXE with a 550 watt power supply, which I have a feeling isn't enough power to fully utilize it. However, after I plugged that beast in I did notice that the overall smoothness of the windows XP desktop is totally gone. It looks as if I was running Windows XP with 60hz on a CRT, if you know what I'm talking about. The picture looks awful on my desktop. By the way I have a Westinghouse 24 inch LCD and my old 7600 GT was flawless. I have this video card connected via DVI->HDMI to my LCD. So if anyone has an idea as to why this would be happening or how I can fix this, I would appreciate it. I tried changing tons of settings in nvidia control panel and that didn't work out.

PLEASE ASSIST!

thanks.
 
hmmmm....well ViperGrendal states his problem was with a GTX280....does this matter? am I looking at the right post on that forum? I'm not aware of this issue at all. i really appreciate the response though, points me to the right direction.
 
Did you install the latest video driver?
(couldnt see any mention of what driver is installed)
 
I do not have the latest drivers installed. I am using 182.50 drivers right now since I was recommended those by a few people as being the most reliable drivers to use. Should I give the latest drivers a shot? I am leaning towards this being a DVI -> HDMI issue with the monitor and video card. I think that forum has the answer but I'm not sure what to look for under those forum posts. I'm sorta noob at this, gonna need some extra guidance...
 
That driver is fine, if you are happy with it, stick with it.

Check your refresh rate isnt set to 30Hz or something daft.
My HDTV lets me use 50Hz and 24Hz, making the mouse jerky for windows use.
 
Does the monitor only allow for a HDMI input and do you need to have HDMI as the input? If not I would just try using a DVI input instead and see if that helps. I'm having no issues with the latest drivers either on my other desktop.
 
This is the monitor that I have: http://www.westinghousedigital.com/details.aspx?itemnum=105

It's primarily my PC monitor but I also use it for my XBOX 360 via VGA (looks like crap with Component and its a GEN 2 360, so I don't have HDMI for it.) When I try playing TF2 via VGA with my new video card, the settings are all screwed up. I try using the 1600 resolution and my colors get all messed up and the screen cropping is out of place. Also, when I installed the latest drivers, that configuration setting under nv_disp.info doesn't have the [nv_SoftwareSettings] or whatever in that file anymore.
 
It looks like the driver is borked.
Uninstall it and re-install.
You might want to give 186.18 a go, it has been rock stable for me (GTX260).
The previous stable driver for me is the 182.50 that you have been using.
 
The problem is that the L2410 gives bad EDID info over HDMI to the video card, and nVidia's official stance is that they will not fix the problem, so the user must do it.

Here's a more specific writeup to deal with the EDID problem:

I've discovered a workaround for this problem. Basically you can use a registry key to override the monitor advertising itself as an HDTV (by setting the number of EDID extensions to 0). Using the following steps, I am now getting proper 1920x1200 resolution on my LG monitor:

1. Start the installation of the latest Nvidia drivers and cancel out once the files are extracted
2. Open nv_disp.inf. By default for the current drivers this is in C:\NVIDIA\WinVista\169.25
3. In the [nv_SoftwareDeviceSettings] section add the following:
CODE
HKR,, OverrideEdidFlags0, %REG_BINARY%, 1E,6D,3F,56,00,00,FF,FF,04,00,00,00,7E,01,00

NOTE
The first 4 bytes (1E,6D,3E,56) in my OverrideEdidFlags0 are specific to the LG monitor I'm using. For other monitors, you will need to replace them. Using Phoenix EDID Designer (Google it), extract the current EDID and open up the byte viewer. The bytes are in byte 8 through 11.

4. Uninstall your current drivers and reboot
5. Install the modified drivers by running the previously extracted setup.exe. By default for the current drivers this is in C:\NVIDIA\WinVista\169.25. You'll get a warning about the driver not being signed because of the modified inf. Just press OK.

key for (another HardOCP user's) westinghouse L2410nm monitor was
HKR,, OverrideEdidFlags0, %REG_BINARY%, 5C,85,80,51,00,00,FF,FF,04,00,00,00,7E,01,00

In your case, of course, the directory for the nVidia driver will be something like C:\NVIDIA\WinXP\186.16 and the EDID number will be different (you must find out your monitor's EDID numbers using the Phoenix EDID Designer).
