Quick summary:<br>
<br>
TV and VGA monitor both connected to a Liva X, myth not quite behaving<br>
as expected, really cumbersome set up (every time).<br>
<br>
Remote control (of the tv) not working with HDMI-CEC.<br>
<br>
Details:<br>
<br>
I recently got a Samsung 6200 tv, that is connected to a Liva X via a<br>
quite thick and long (35 ft) HDMI cable. It was quite expensive and<br>
rated for high speed/bandwidth/resolution. Only later did I learn that<br>
some hdmi cables can't handle CEC which is apparently how the remote<br>
control signals get from the tv to the myth box.<br>
<br>
Can the Liva X handle CEC and thus receive the TV's remote control<br>
signals?<br>
<br>
The TV remote has no effect on myth, but I haven't configured anything<br>
manually yet.<br>
<br>
The liva X is running Debian Jessie and when I plug in the HDMI cable,<br>
the desktop adjusts automatically and I have a double-width dssktop<br>
with the TV to the right of the monitor with the VGA connection.<br>
<br>
Both the VGA display and the TV have 1920x1080 resolution. Xdpyinfo<br>
shows screen #0 (the only screen) with 3840x1080 pixels.<br>
<br>
The only way I've found to display the frontend on the TV is to start<br>
another instance of the frontend on the extension of the desktop that<br>
displays on the tv:<br>
<br>
mythfrontend -geometry +1921+0<br>
<br>
There has to be a better way. While the frontend that runs on the VGA<br>
screen displays properly, the one that displays on the TV exceeds the<br>
screen on all 4 sides. The bottom half of the date and time (at the<br>
bottom of the screen) are cut off. 1/2 of the mythtv logo at the top<br>
is also cut off, and the same happens on the left and right sides. In<br>
the days of CRT TVs this would be overscan, but what is happening when<br>
all displays are digital? How can this be adjusted? Why is it happening<br>
in the first place?<br>
<br>
In order to get the sound to be played through the TV I have to change<br>
the audio settings to "Digital Stereo (HDMI)" output and I have to give<br>
myth focus with a mouse click in order for the keyboard commands to even<br>
be seen. And after all this, when I start playing a recorded video, it<br>
starts on the TV but immedeately (after 1 second) it gets displayed on<br>
the VGA screen. After some more experimentation, I did manage to get<br>
the video to display on the TV. I had to add the -w option:<br>
<br>
mythfrontend -w -geometry +1921+0<br>
<br>
Is this the expected behavior? The window borders are not displayed and<br>
myth is still "overscanned" There is a very thin band of the window<br>
border at the bottom of the screen when displaying video. The screen<br>
size doesn't appear to be handled correctly when dealing with the TV.<br>
<br>
It would also be nice if the audio output could be set automatically.<br>
When using the VGA monitor, the audio goes to computer speakers from the<br>
audio jack, when using the TV, it should go through the HDMI cable.<br>
<br>
At least now myth is useable on the tv, but having to get up and<br>
go to the computer keyboard to control it is not really acceptable.<br>
Thus the second issue.<br>
<br>
I have found this:<br>
<br>
<a href="https://www.mythtv.org/wiki/HDMI-CEC" rel="noreferrer" target="_blank">https://www.mythtv.org/wiki/HDMI-CEC</a><br>
<br>
but it seems to require additional devices, which brings me back to<br>
the question above: can the Liva X handle CEC? Does anyone know if<br>
there is something special about certain HDMI ports in Samsung TVs<br>
as opposed to others, like seems to be implied in some web pages I've<br>
read? The second HDMI port on the TV is labeled HDMI/DVI. What is<br>
the difference? Should I plug the myth box into this one?<br>
A lot of the content in the above page seems to be geared towards<br>
lirc, which I'd rather avoid if it's possible to just use the CEC<br>
signals through the HDMI cable.<br>
<br>
Is anyone using the remote of a samsung TV via HDMI-CEC to control<br>
myth on a liva without additional hardware? If this is not possible,<br>
with what other devices can this be achieved? I have found:<br>
<br>
<a href="https://www.pulse-eight.com/p/104/usb-hdmi-cec-adapter" rel="noreferrer" target="_blank">https://www.pulse-eight.com/p/104/usb-hdmi-cec-adapter</a><br>
<br>
and see that there are IR to USB adapters, but I'd rather not use<br>
additional hardware if I can do this with the HDMI cable alone.<br>
<br>
Any hints or help will be gratefully received. Thanks!<br>
