Hi,<br>
<br>
I have an older wide screen (16:9) plasma with a native resolution of<br>
1024x768. It will accept a resolution of 1280x720, but it overscans. In<br>
the past I just used a setting in the nvidia driver to compensate for the<br>
overscan. At some point that feature of the driver went away. My system<br>
defaulted to the native resolution of 1024x768 and myth has been treating<br>
the display as a 4x3 screen. I set out to fix this this weekend and found<br>
a page on the MythTV wiki that explained how to set the aspect ratio using<br>
displaysize in the coefficient.conf file. Trouble is adding that line has<br>
no effect. It seem that the setting is controlled somewhere else. I'm<br>
running mythbuntu 12.04.<br>
Anyone know what could be overriding that setting?<br>
<br>

coefficient.conf?<br>

Xorg.conf<br>
I should really proofread better when using my phone for typing email.<br>

You need to either set the DisplaySize in X or set the resolution and DPI<br>
and let X calculate the display size, so it can calculate the physical<br>
aspect ratio.<br>

Yep. That's the page I followed.<div class="im"><br>
<br>
The displaysize line in X had no effect. I think something else is<br>
overriding it, but I can't figure out what.<br>

Yes, most distros--in their quest to "help" you by making X config-file-less so you don't have to write a config file--do fun things like hard-code a -dpi setting on the command line used to start X, which tells the server to completely ignore any configuration-file specified DisplaySize values and even driver-specific configuration-file values such as DPI (and also makes the DPI meaningless). And, to make matters even more fun, different distros have different ways of starting X, so finding that -dpi can be a challenge (some may put it into the startx script, others call startx -- -dpi 100 or similar from some other script and others use other mechanisms).<br>
<br>
It's possible something like this is overriding your configuration.<div class="HOEnZb"><div class="h5"><br>
