***I don't know if this is the right section i should be in - it deals with HTPC but also tv's being used as monitors.***

I have a 52' samsung LN52B750 and hooked it up to my rig/HTPC (using a HDMI to DVI cable) which is connected to a GTX 275 O/C. (both TV and video card are HDCP capable)

Here is my problem, I don't know if it's from the cable, my setting or what but i'm getting alot of white pixels in the black areas. I understand tv's cant produce full black but i've never came across a problem with this. I'm attaching a screenshot of a .dream on my background so you can see what i mean by white pixelations. I'm kind-of baffled from playing with all the settings to figure if i could correct the problem, I actually have a huey PRO comming to get my tv calibrated but i'm still kind-of going back to the cable.

(just fyi, my 52' is wall mounted - so the last thing i want to do is pull it off the wall to change out HDMI-to-DVI back to VGA-to-DVI to test it). If anyone has an suggestions or been through this problem before - let me know, i'm kind-of out of ideas here.

If you need anymore information, please just ask.

Thanks in advance

(you can see in the dark areas around the corners the white pixels standing out)

What's your refresh rate set to? I have a Samsung LN46A550 that has a refresh rate of 60Hz. I get horrible shading if I try to set my refresh rate to anything other than 60Hz.

Do you have colorspace set to 16-235 or 0-255? Do you see the problem in video or just desktop?

it looks like just desktop and applications - movies and full screen applications don't seem to have any white pixels in them. I have it at Full 0-255 with color enhancement checked. I do see it in flash games and the desktop
