DELL W2300 LCD TV / Monitor - Wrong resolution in XFree86

Edweirdo

I just bought the DELL W2300 LCT TV and I really like it as a TV and as a monitor. However, I can't get my X11 to use the correct resolution of 1280x768. I know I need to add my own "Modeline" but I have no idea what it is supposed to be. I've used this modeline calculator but I have no idea what I'm doing.

I have the manual, of course, and can see the specs, but I'm not sure what relates. At leat I haven't gotten it to work yet. Here are the specs:

Not too many people saw this message. I was hoping some really smart people might see it now (me not being one of them).

nepenthe, thanks for the information. However, I do understand the Modes lines for the graphics card screen resolution. However, my problem is that I can't get X to do the right Monitor resolution because I can't figure out what the "modeline" line should be for the monitor (in the Monitor section). There are ways to figure what the line is supposed to be with the details I have, but I'm not sure how to do it.

I was just thinking (after looking through my xfree.log) that maybe my graphics card can't do 1280x768. I have an older nVidia GeForce card. That would suck greatly.

freedonkey, I'm not sure what is wrong with your keyboard, but it looks like you missed a bunch of letters from your words.

It is not my monitor that is the problem. I know what the resolution is for the monitor, it's just that I can't get my graphics card to do it. I finally realized that maybe my old video card (nVidia GeForce 256 SD) can't actually do 1280x768 resolution.

I got a new computer and it has a new video card which can actually do the resolution I want. I still had to calculate the modeline using the calculator I specified, but it works now.
