A friend of mine and I are trying to get a Linux HTPC working with a Mitsubishi ws-55809 HDTV. Ideally we would like a 16:9 widescreen resolution, but thus far have only managed to get it to work in 640x480 and oddly enough 920x480, neither of which are 16:9 aspect ratios. The TV displays these resolutions in 1080i mode.


Wondered if anyone might have the same model of TV and already figured out good modeline settings for it, or if anyone else had any suggestions to help us find them.


I've noticed lots of other people here asking similar questions and I wonder if it wouldn't be beneficial if someone with the knowhow would write a "Finding TV Modelines for Dummies FAQ."


Thanks,

I'm not sure how much that link will help you. The example given was for a 720p resolution which I know the mitsu rptv will not playback. Using the tool "Colas XFree Modeline Generator" is really intended for multi sync monitors. I wouldn't trust using this with an expensive rptv unless you want to test your service warranty. I actually sat down and translated powerstrip settings to modeline format.


The following works for my 46" 16:9 mitsu hdtv. 960x540 is perfect for DVD playback (with not too much overscan) and for mythtv. This is through a Geforce 2 MX. Ymmv.

I use 848x480. If you can't do 720p with your hdtv then this is the best you can expect to get. 1080i looks like hell with computer graphics. It isn't worth it. Besides DVDs are no better than 848x480p anyway so there is no penalty. This is true for windows too. OS doesn't decide what resolutions look better than others. The HDTV or projector does.
