I've just set up a two monitor setup with a laptop, with the second monitor being a 31.5" LCD HDTV, connected via DVI. Since I'm sitting very close to the television (2-3 feet away, probably) I can see a few irritating pixel issues.
First of all, there are these vertical bands on the screen where there is a ton of aliasing. Since I'm not an expert on graphics, I'll be a bit more specific, because I might be saying something other than what I mean. At certain vertical lines on the screen, points that should be one pixel wide would be two or three. It's a really irritating effect that makes it hard to read on the TV.
Secondly, along these lines and at various other locations on the screen, there is a bit of jitter. Pixels will be jumping back and forth between black and white at irregular intervals and at boundaries between black and white.
Finally, there is a frustrating shadow that appears in some images on occasion. What I mean by this is that about 5 to 7 pixels to the right of text, the blinking text cursor, and other dark-on-light situations, there will be a faint shadow of whatever is there. It is extremely faint, so it is not as viewable straight on, but just a slight angle up or down will make it very visible.
Here's what I've tried so far. I've found a menu in the TV's settings regarding this sort of stuff (I think). The options are: H-Position (moves the image horizontally), V-Position (moves the image vertically), Clock (seems to stretch the image horizontally), and Phase (might make a difference with the jittering?). I've adjusted the first three so as to make the image fill the screen entirely, and I tried to use the fourth to decrease jitter, but the problems persist.
There's probably one last thing that I should tell you: In Screen Resolution in Control Panel, the resolution of the monitor is set to 1280 x 768, the maximum that appears to work on the television. However, when I press the Info button on the TV remote, it reports a resolution of 1360 x 768, a full 80 pixels off. I do know that if I set the resolution of the output to the TV to 800 x 600, the TV does report the proper resolution, and I don't seem to have any of the problems that I'm reporting here.
Can anyone confirm or deny my theory on why I have this problem, and help me to fix it either way?
I've included a couple of pictures of what I hope can help you guys understand the problem. The first is of the text of this question, where the letter 'i' has the aliasing that I'm talking about, and the second is of the shadowing next to the blinking text input cursor. (The second picture is very hard to see, but look closely at about 12% zoom and you'll notice a darker area 3-4 TV pixels to the right of the cursor).
Thanks for the help in advance!
