Well, if that's the case, then you have X misconfigured and you're abusing<br>
the "Video aspect override" setting to make it appear correctly--the 2<br>
wrongs to make a right approach. See<br>
<a href="http://www.mythtv.org/wiki/Display_Size" target="_blank">http://www.mythtv.org/wiki/<u></u>Display_Size</a> (Or you have Xinerama enabled<br>

It's entirely possible that X is misconfigured, but I fought with it for<br>
quite a while and even to get it to stay in 720p I have to issue a xrandr<br>
command in my .xsession script because I couldn't force the preferred mode<br>
in my xorg.conf (it used to stick, but an update to X broke it). Hmm... I<br>
just looked up man page for xrandr and I see there's a --fbmm option that<br>
can set the display size, so I'll look into that. Maybe if I set that I can<br>
get rid of the override and have everything work right.<br>

The "Video aspect override" setting shouldn't exist and only provides a<br>
way for people with broken configurations to make it seem like things<br>
aren't broken without actually fixing the brokenness. It only adds to<br>
confusion when users are configuring their systems, especially when it<br>

Yep. The "brokenness" in this case is primarily due to my HDMI->Composite<br>
converter, but I'm able to get it to work well enough for now. There comes<br>
a point where you've fought enough with arcane config files and arbitrary<br>
package changes and you just want it to fricking work.<br>

Sounds like you're using 1280x720 output on your HDMI that's going to an HDMI->Composite converter, which outputs NTSC Composite (which is assumed by your TV to be 4:3). If that's the case, you simply need to tell your X the proper DisplaySize to use. (While nvidia drivers allow you to specify a DPI value, doing so would require doing more math, so I'm giving examples using DisplaySize--which presumes that you did *not* specify DPI to the nvidia drivers--if you are using nvidia drivers.)<br>
<br>
If you have a 16:9 (physical aspect ratio--as in comparing the physical width/height of the) TV, you simply need to specify a 16:9 aspect ratio on the DisplaySize, such as:<br>
<br>
DisplaySize 325 182<br>
<br>
in the Monitor section of the X config file.<br>
<br>
If you have a 4:3 TV, you need to specify a 4:3 aspect:<br>
<br>
DisplaySize 325 243<br>
<br>
I'm guessing you need the former. Just make sure in your Xorg.log, you see something on the order of:<br>
<br>
(**) Dec 10 18:16:47 NVIDIA(0): DPI set to (100, 100); computed from "DisplaySize" Monitor<br>
<br>
(though you may well have different DPI--the important part is that it was computed from the DisplaySize, rather than from some (broken) --dpi setting on the X command line that your distro decided to create havoc by including or similar). Also, FWIW, your needing to use xrandr to force the 720p does make it sound like your distro is doing something terrible like specifying a --dpi argument to X.<div>

Something changed in a version of X maybe ~8 months ago that broke it. PreferredMode is completely ignored. I'm using the built-in Intel graphics (i3 Sandy Bridge), not nVidia. But I will investigate the DisplaySize first in xorg.conf and if that doesn't work, then as an argument to my xrandr command.<span class="HOEnZb"><font color="#888888"><br>

DisplaySize is accepted, but Myth apparently doesn't use it. I used the actual measured display size. Maybe it can't use non-square pixels (1280x720 pixels is 16:9 but 559x419 mm is 4:3)? I couldn't find the "Monitor Aspect Ratio" setting per se, but I did see something like that if I enable separate modes for GUI and video playback. I don't use that feature, so maybe that's why it's not working for me. Anyway, I went back to using the Aspect Override to fake that I have a 16:9 screen so that recordings will fill the screen and not be horizontally squashed. So, from my perspective there is still a need for that setting.<br>
