Hi guys,
I'm trying to get Ubuntu to recognize my projector at it's native resolution. I'm using Jaunty at an IBM T60 laptop (ATI video), in combination with a Mitsubishi HC1500 projector which is 720p. I use a regular VGA cable for the connection.
When I go to System-->Preferences-->Display, it actually recognizes the extra monitor as Monitor: Mitsubishi. The regular one for my laptop is also there and is called Monitor: Laptop 15". The weird thing is that I can set the laptop monitor to 720p resolution, but NOT the projector. Also, if I set 'Mirror screens', the option disappears completely. Now my question is how do I get Ubuntu to do 720p over my projector?
I found a modeline with the MythTV guys:
## Doesn't claim to support native (1280x720) over VGA, but it does just fine
# ModeLine "720p" 74.25 1280 1392 1448 1650 720 722 728 750
However, I dont know where to put this so it works. I tried some places in xorg.conf that made sense to me, but so far no show. Any advice?
