How do I find out the specs of an LCD TV (for the modeline)

kamagurka · 2007-10-17 11:30:31

I bought a Toshiba 37x3030D LCD-TV, and I'm planning to hook it up to the DVI-out. However, I have no idea how to find out the different specs that X needs (vsync, hsync, that sort of thing) and I can't find a readymade modeline anywhere. Is there a decent tool for this, or something?

dvi is digital, so afaik, you don't need the modeline. Just plug and go.

For the record, I needed the modeline.
Also for the record, if you want a setup-friendly TV, go Toshiba. They have all the information needed to generate a modeline in the handbook, which is rather unusual, to my knowledge.

There's this really nice utility if you need to figure out a modeline, called gtf. Lets try 1600x1200@85;

[pelle@pelle-desktop ~]$ gtf 1600 1200 85

  # 1600x1200 @ 85.00 Hz (GTF) hsync: 107.10 kHz; pclk: 234.76 MHz
  Modeline "1600x1200_85.00"  234.76  1600 1720 1896 2192  1200 1201 1204 1260  -HSync +Vsync

[edit] if you use any kind of modern monitor, you can leave the vertical and horizontal refresh rates out. These should be automatically detected.[/edit]
btw, i can even start X *without* an xorg.conf, so i was rather surprised you actually needed a modeline for your monitor...
