I recently purchased a 16:9 aspect ratio High Definition 32" LCD TV (Vizio L32HD10A). I have it connected to my PC via an RGB analog input. According to the documentation, recommended resolutions for connecting to a PC are 1024x768 @ 60Hz and 1366x768 @ 60Hz. With some tweaking to my xorg.conf file, I have it working under X at a resolution of 1024x768@60, but no luck so far getting it to work at 1366x768@60.

I am currently running Ubuntu 6.06 LTS (Dapper Drake) with kernel 2.6.15-26-386. After searching the web, I learned about of a couple of programs to help me out. The first was 'read-edid', which created an XFree86.conf monitor section entry based on my TV's Extended Display Identification Data. I am going under the assumption that this entry will work with X.org as well as XFree86. Somebody please correct me if I am wrong about that. Below is the entry created by read-edit:

The second program I enlisted was 915resolution. Using this program to read my on-board video's VBIOS, I got the following:

As you can see, 1366x768 is not one of the 865G's supported resolutions. Using 915resolution again, I substituted 1366x768 for 1600x1200 to give me the following:

The result after restarting X was a 'Signal Not Supported' message from my monitor. Based on some research, I decided to try resolutions of 1360x768 and 1368x768. Changing my xorg.conf to these resolutions does not work at all. Using 915resolution to get my graphics chip to use either of these resolutions, oddly enough, allows me to change my monitor to 1280x1024 @ 60Hz, but not to 136?x768. Without adding one of these resolutions, I could not go higher than 1024x768 @ 60Hz. I really would like to get this TV working with a resolution that is better suited to the 16:9 aspect ratio. Does anybody have any ideas on what else I might try? I would really appreciate any ideas you could provide. Below is my current xorg.conf:

I'm not familiar with this method of specifying modes, but I do notice that the mode defined in the Monitor section is called "1366x768" while the mode you're trying to specify in the "Screen" section is "1366x768@60".

Try removing the @60 bits and see if that makes a difference.

I also have a 16:9 HDTV with a reolution of 1366x768, I am using dapper, and it doesn't work either. I am using Xubuntu, and I have noticed that when changing to mode 1280x768 it sometimes syncs up to 1366x768, it isn't perfect, but it is better than nothing. Let me know what happens.....looking into read-edid.

I've also got a Vizio L32HDTV10A and I'm having trouble getting it to work with the i810 driver (Intel G965 chipset in this case). I stumbled upon a video bios tool called 915resolution and I was able to get it into 1368x768 resolution (note 1368 != 1366) once but then I couldn't get the horizontal alignment correct. 915resolution doesn't recognize my bios but it seems to (sort of) work if I added "-c 945G" to the options.
