User Experience and Caveats

A 42 inch widescreen LCD TV. Native Resolution is 1366x768. To avoid the hassle of modelines, if using the VGA input, you can simply set your xorg to to the closest possible built-in modeline in X that the TV finds acceptable, then the TV will take the image and scale it and center it to fit the screen. For me, 1280x768 works well, and fills the entire 1366x768 screen area with no overscan. The picture quality is exceptional, and indiscernible from 1366x768.

DVI input on this TV is limited according to the manual. It states that computer input over DVI is limited to 640x480, however, if a proper 1366x768 modeline is used, the TV shouldn't know you have a computer connected anyway. The component connectors support up to 1080i also, so these may be used with graphics cards with HD component output.


The TV aspect ratio problem below appears to no longer be a problem with the latest versions of myth (.21+)

This TV incorrectly reports that it has a 4:3 aspect ratio under certain circumstances, including in the latest SVN of mythtv (as of Dec 12 2007). Therefore myth will Pillarbox all 16:9 content incorrectly displaying it as 4:3 with the sides cut off, and black bars on your 16:9 vizio VW42L TV. To get around this problem, use the custom resolutions feature in the appearance options under setup from within mythfrontend. Select separate resolution for GUI and video playback, leave both the GUI and playback resolutions the same, which should be your X resolution (the same resolution that mythfrontend is displayed at in fullscreen, and then use the aspect ratio option on the same line to set to 16:9 instead of default. 16:9 HD programs will now display properly and fill the entire screen with no pillarboxes.
