I've run XBMCLive off of a USB thumbdrive using my work laptop and a VGA connection to an HDTV before without issue. That was using my 5.5 year old Samsung 46" DLP set. I've tried with two laptops now on a new Sony LCD (KDL-32BX300) using the VGA connection and had identical odd results.
From my TV's manual the following resolutions and sync rates are supported:
Whenever I try the 1360x768 (native res. for TV) resolution in XBMC a little less than half the screen is cutoff. If I use the same resolution on the laptop's LCD screen everything is fine, although scaled. It's not that the picture is scaled incorrectly, the whole picture is there, I just can't see the right half.
If I use 1024x768, the entire picture is there, but it's a 4:3 aspect ratio, so I then have to scale it to 16:9 via the TV's internal scaler and objects are wider than they should be.
I tried checking the xorg.conf file, but none is being generated by X, so that's no help. The xorg.log file doesn't seem to be having any issues, in fact a lot of EDID info is recorded:
I'd try setting up the 1360x768 modeline, but since I don't have an xorg.conf file, I can't do that.
Eventually, I'm going to get a Displayport to HDMI cable, which should solve this issue. But, until then, is there anything I can do to get XBMC and my TV to cooperate and display correctly at the TV's native resolution?
