openSUSE13.1 HDMI Resolution Problem

keellambert · July 24, 2014, 12:54pm

Hi,

display connection with the vga cable works ok

with the HDMI cable the full desktop can only be viewed at 1680x1050 resolution

on boot up kdm correctly detects the monitor, part way through kwin/kde
initialisation the resolution changes from 1920x1080 to 1680x1050
but only with the HDMI cable, ported from either the DVI or HDMI card output

anyone else having similar problems?
is a bug report needed?

xrandr and os info below

conclusion:
this is kde or radeon driver problem and nothing to do with the kernel or monitor

cheers

As you say this is on 13.1, which is a normal supported version of openSUSE, I wonder why you post this in the Pre-release/Beta subforums. Or am I missing something?

keellambert · July 24, 2014, 4:30pm

Kernel: 3.15.6-1.gfdb2dde-desktop x86_64 (64 bit)
Desktop: KDE 4.13.3

Are these now non-beta?

hcvv · July 24, 2014, 5:01pm

Better publish that prominently instead of simply saying 13.1 in your title.

Any chance you can try another HDMI cable?

Does the problem exist if you login into TWM or IceWM instead of KDE? If it
does not, try this to see if behavior changes in KDE:

1-log out of KDE
2-login on a tty
3-include the following in ~/.kde4/share/config/kdedrc
[Module-kscreen]
autoload=false
4-log into KDE

If the same problem exists in all, you may be able to use xrandr in an xinit
script, or /etc/X11/xorg.conf.d/50-monitor.conf to declare 1920x1080 be used
on the HDMI connector. It shouldn’t be necessary, but could be your only
solution.

http://fm.no-ip.com/Share/ has several xorg.conf* files you can use for
guidance. Also find there setup for guidance if you want to try using xrandr
via /etc/X11/xinit/xinitrc.d/.

The wise are known for their understanding, and pleasant
words are persuasive.

Q1. Two different cables were used.
One HDMI-HDMI the other DVI-HDMI
So its not cable related

Q2. Yes, all desktops show similar attributes

I’ll try an xinit script tomorrow, dawn is not far away now.

cheers, and thanks for the quick feedback

keellambert · July 26, 2014, 10:21pm

Apologies for time wasting

Tried the ASUS 24T1E Monitor TV driven from,

laptop HP Pavilion G7 with openSUSE13.1, and
laptop Toshiba-Satellite-L670 with win7

both with exactly the same results

conclusion, its the monitor firmware, all other modes work except
1920x1080/i using the HDMI interface

this thread is considered closed

cheers

fwiw

this anomally is covered in two articles,
http://evilshit.wordpress.com/2012/08/09/how-to-remove-overscan-on-hdmi-1080p-output/
and
http://www.rarst.net/hardware/asus-27t1e/

to enable the 1920*1080 mode, without overscan, the HDMI sound has to be disabled

cmd on this pc,

xrandr --output DVI-0 --mode 1920x1080 --set audio off

NB.

DVI-0 is taken from the status output of the xrandr cmd,
so may/will be different on other hardware
the above command can be placed in file:///home/<username>/.bashrc
for automatic execution on booting

sound can be obtain via the ‘build in Audio Analog Stereo’ driver via the 3,5mm
output from the sound card/ motherboard output socket to external speaker

not ideal but it works

hth someone

cheers

Correction

to prevent overscan on the HDMI output the HDMI sound has to be disabled
the sound output from the pc/laptop sound card can be connected to the HDMI sound input
on the monitor, cable required 3.5mm (sound card output) to RCA R+L (HDMI audio-in)
(so external speakers are not required)

from the user manual, para 1.3.3 page 6, quote,
4. Audio-in for HDMI (if no sound from HDMI) for audio signal input from the
HDMI device without transmitting audio signal over the HDMI cable

note made to read the user manual more carefully in future
