Hello. Of all the people visiting this forum, can someone post the

XF86Config file in RH8 that they are using, to enable 540p/1080i at

60hz V/33.75kHz H?


In addition, I could use a modeline for a setting that minimizes overscan

as much as poissible. Thanks in advance. -Gary

You haven't provided enough information for us to help you...

We'd need to know your ramdac speed and the horizontal &

vertical refresh speeds that you monitor supports. Even then

front/back porch information might be necessary too.


You could try generating your own using the tools at freshmeat.net

(search for modeline - there are a bunch of tools) I've been using

videogen today..


You can get some of the information you need from your xserver

log /var/log/XFree86XXXXX (I can remember it's in /var/log )


Good Luck,


Andrew

First, the distribution you are using has no impact on Modelines. If you want to provide version information your XFree86 version might be a bit more helpful, although Modeline interpretation is a fairly static part of the codebase. Other helpful information would be what HDTV/monitor/projector/etc you are using, and your video card.


Here's some settings I've been using that are related to home theater. NOTE: None of these have been tested on anything other than a computer monitor. Only about 2/3 of them work on a computer monitor. It's my work in progress. Not all of them are meant for HDTV output (some of them may cause your screen to explode and risk injury to anyone in the room. Or not, as I said they haven't been fully tested). You can tell fairly easily which ones are 540p though, I haven't created any 1080i timings yet. Also I have no idea what HDTVs use negative or positive polarity, you might want to check out your specs and adjust accordingly. These are mostly set to negative polarity.

When you get bored of those and want to make your own:


Convert powerstrip modelines to XF86Config: http://www.hut.fi/Misc/Electronics/f...2rgb/calc.html


Lots of good examples (use the above link to convert): http://www.digitalconnection.com/Sup...ffnotes_17.htm

Your best bet is to use one of the example modelines and start X. Once in X, open a terminal window and run xvidtune. It will allow you to change the sync values and width/height. After you have it set where you want, remember those values and modify /etc/X11/XF86Config.

Here are some modelines I have been testing.

I have used the 1024x768P, 720P, and 480P settings with some success on my Sampo HDTV. For the 720P setting, I had to tweak the Sampo display sizing a bit.


Most of the settings I got from Powerstrip's ability to export XFree86 modelines.


If anyone tries these on an HDTV display, please post your results here.
