<div>I think the problem is that I misread the
specification on the projector. While it says
that it does 1080p, the maximum data rate is
1280x720 so the 1080p must be with an analog
input. Same with the monitor. It has a native
resolution of 1280 x 1024. Per the
recommendation of everyone here, I set the TV up
from my initial setup of 1280x720 to 1920x1280
when I upgraded to Mythbuntu-16.</div>

<div>Option "metamodes" "VGA-0:
nvidia-auto-select +0+0, HDMI-0: 1920x1080
+1280+0"</div>
<div><br>
</div>
<div>When I was running Mythbuntu-8 which drove
the projector and the TV just fine, I had
everything set to 1280x720 as that is all the
TV signal is anyway.</div>
<div><br>
</div>
<div>So now I have to decide if I want to use
the TV at 1920x1080 or downres so I can use
the projector a few times a year or find some
way to have the computer auto detect without
turning the TV black. I believe there was also
an issue with the Sony sending bad EDID data.
I just read something about auto detecting
1360x768 instead of something useful. Might
be a different model but I recall there was an
issue. Maybe there is a way to have X pick
between 1280x720 and 1920x1024???</div>

<div>Well, I think I am at least understanding
why it doesn't work.</div>

<p>I don't think I ever set up a frontend where I hadn't had to
tweak the xorg.conf for the specific screen ( monitor, tv,
projector, etc ) at least a little ( ok, the Android frontend on
my Shield went surprisingly easy ).</p>
<p>Whether it be dealing with overscan, underscan, adjusting mode
lines for some specific resolutions/frame rates, or dealing with
an older xorg that couldn't handle the device not being there when
it came out of suspension, bad EDIDs, etc.</p>
<p>The issue is that these adjustments are generally specific to
that device and don't just work for all of them.</p>
<p>For one of my frontends, which has a primary output device (TV),
and a secondary I only use a few times a year (Projector), I ended
up creating an xorg.conf which has two SERVERLAYOUT sections, each
of those two sections specify their own DEVICE, SCREEN and MONITOR
sections.</p>
<p>Most of the time, my frontend auto logs in the myth user, and
automatically starts "startx --layout TV". For the couple times a
year I use the projector, I logout then, log in manually, and
"startx --layout PROJECTOR".</p>
<p>FWIW: I tweaked the xorg.conf for the separate devices
individually, till I had everything the way I wanted it for that
output device, and then combined them, makes testing a lot easier
as well.</p>
<p>Of course none of this solves your immediate issue, just a
suggestion on how you can run both configs going forward when you
do get it working. Stephan Worthington already gave some pretty
good advice in that category.</p>
