Sorry again, this was a knee-jerk reaction to the "Linux is beautiful, Android is crap" attitude around with the new Kodi technical management (http://forum.kodi.tv/showthread.php?tid=...pid2331206 + http://forum.kodi.tv/showthread.php?tid=...pid2331545).

It will soon not matter at all Wink

I have a question. How do i adjust the scaling mode with the use of xrandr?

**fritsch** · 2016-05-09, 18:33

Quote:Resolution 1366 x 768
Display Format 720p

And supported input formats:

Quote:1080i, 480i, 480p, 720p

This ^^ resolution you want to have, cause that really is your native resolution. So from the specs the 720p mode (1280x720) is correct. Everything else the TV is scaling for you which you don't want.

Try this custom modeline:
Modeline "1366x768" 85.500 1360 1440 1552 1792 768 771 777 795 +hsync +vsync

please and additionally see if one of those here: https://www.mythtv.org/wiki/Modeline_Database#Phillips (search the 1366 modes) does work for you.

Never mind. i tried scaling and it gave me a blank screen.

I went back to catalyst temporarily to see what it does differenty and it uses for 1600x900 a 30htz refresh rate but also it uses monitor scaling and not gpu scaling. Is that helpful to know?

lizzi · 2016-05-09, 19:27

Also when i used graphics scaling with the catalyst i had to set underscan to 7% at 1600x900 30hz under maintain aspect ratio.

**fritsch** · 2016-05-09, 19:39

Nope - you don't want 30 hz for sure. You want the native resolution which is 1366x768 for you,

We must have cross posted. I just now saw this. Will try that in a little while. Thank you.

You know what's funny is that i have seen the specs for the tv and see that 1366x768 is the default resolution for the tv. Also for this laptop that was the default resoultion for the lcd built into it but open source driver doesn't recognize it as a viable resolution. Even catalyst doesn't see it as a viable resolution

lizzi · 2016-05-09, 20:59

Even catalyst doesn't off 1366x768 as a possible resolution.

**fritsch** · 2016-05-09, 21:15

So - then add it ... as now described and showed 10 times ...

you are doing it wrong :-( Man I told you before ... all three steps that are needed ...

**fritsch** · 2016-05-09, 22:10

What's so hard to do:

xrandr --addmode HDMI-0 "1368x768_60.00"

xrandr --output HDMI-0 --mode "1368x768_60.00"

to just follow what I ask you to do ... ?

i did copy and paste those lines into the terminal just as you asked and when i entered the last line of text and pressed enter i was rewarded with a blank screen

Good - then keep 720p which is the only supported input according to your vendor manual.

Edit: And no - before you ask - that fglrx mode with 30 hz is also internally transformed to the native output.
