[solved] Screen width problem on widescreen TV
I'm trying to get X.org (with Fluxbox) to display correctly on a widescreen TV. However, the width seems to be wrongly configured. ("Screenshot", 26k JPEG) Or perhaps the sync or refresh rate - I don't know anything about that. I'm pretty noob, so don't hesitate asking me to check log files or whatever :)
The manual for the TV has this table. I only included the mode I'm interested in (there are corresponding rows for lower resolutions). Code:
Resolution | Horizontal refresh rate | Vertical sync rate | Pixel clock | sync polarity ModeLine "1360x768@60" 84.50 1360 1392 1712 1744 768 783 791 807 +hsync +vsync (The ModeLines are calculated with xtiming.) Oh, and I'm using Gentoo with kernel 2.6.18. Graphics board: Radeon X600 |
Check out the question below:

Do you think that the hor/vert rates can be causing the "distortion"?
I took a look at that thread before, but it didn't really help me. But I guess I'll try hwinfo. And, do you think that the TV manual shows the wrong values? Seems odd to me. Thanks, however. |
Try to remove all other sizes from the "Modes" lines in the Screen section to force "1360x768@60". The X server generates standard mode lines on its own and you may not actually get the desired size. In the current state, you can find out with xdpyinfo (you may have to emerge it if it's not there). If you don't get what you had asked for, the log file will tell you what has been rejected and why. BTW, where did the
HorizSync 30 - 61 VertRefresh 60 - 75 lines come from? Did the server query the screen? Or did you enter that? Hope it helps, mlp |
mlp68,
I'm pretty sure I've seen in the Xorg.0.log something that showed that X was using my desired mode, but I'll try removing the other modes as you suggested. The HorizSync and VertRefresh lines I entered myself. I got those values from the manual for the TV - the same as the other values. |
still having problems

The problem applies for the 1024x768 mode too, and also for when I Ctrl+Alt+- from the 1360x768 mode (which I don't think are the same... or are they?). The tv should work as a computer screen some way, because I've run Windows (with the same system and graphics card) on it without a problem. |
Sorry that you are still fighting this. I have since the last posting replaced 2 monitors with widescreen LCD's and gotten them to work after some tweaks, which may or may not help you.
In my xserver's log file, I see Quote:
