tvservice doesn't find the connected monitor

Wickie1 · May 22, 2021 at 12:22 PM

Hardware

Raspberry Pi 4 Model B Rev 1.2, BCM2711, c03112
Monitor: ProLite T2453MTS-B1, 1920x1080
Hifiberry

Libreelec

LE 9.95.3
upgraded via Libreelec-Addon from 9.26 to 9.95.2 and one day later to 9.95.3 (yes, I know, it's not recommended)

Issue

Code

tvservice -l
0 attached device(s), display ID's are :

Nevertheless the picture is shown. Kodi works without any problem.

When the system boots and the splashscreen appears, the picture is pale. The black is only a gray.

For that reason i configured in /flash/config.txt

Code

hdmi_pixel_encoding:0=4
hdmi_pixel_encoding:1=4

With this settings I corrected the monitor mode:

Code

tvservice -s
state 0x120009 [HDMI CEA (16) YCbCr444 full 4:3], 1920x1080 @ 60.00Hz, progressive

It worked with LE 9.26 but due to the missing monitor detection it has no effect at LE 9.95.

The issue with LE 9.95.3

Code

tvservice -p
Powering on HDMI with preferred settings
[E] Failed to power on HDMI with preferred settings


tvservice -m CEA
Group CEA has 0 modes:

The same with LE 9.26

Code

tvservice -m CEA
Group CEA has 15 modes: 
mode 1: 640x480 @ 60Hz 4:3, clock:25MHz progressive
...
          mode 31: 1920x1080 @ 50Hz 16:9, clock:148MHz progressive

Unfortunately I didn't write down the output of tvservice -l.

Forgot the debug log:

Updated to Libreelec 9.95.5

The bug is still present.

Am I the only one who needs to switch the monitor mode?

Found this thread.

This is normal - tvservice uses the legacy functions which aren't relevant for master builds anymore (we still kept the legacy programs for testing ATM).
Use eg modetest to find out what displays are connected and what resolutions are supported.

It's at least a base for a further search.

Same problem:
Videos playback darker in LE than in Roku Emby app on same TV

Quote from "Da Flex

On LE 9.x add hdmi_pixel_encoding=2 to config.txt. On LE 10+, this setting belongs to cmdline.txt (I still have to figure out the syntax for this).

Found modetest:

Code

…
trying to open device 'vc4'...done
Encoders:
id	crtc	type	possible crtcs	possible clones
31	76	TMDS	0x00000008	0x00000001
39	0	TMDS	0x00000010	0x00000002
47	0	Virtual	0x00000001	0x00000004

Below there are a lot of settings and flags.

I'll guess I have to figure out, which parameter I have to choose and put to the cmdline.txt.

tvservice doesn't find the connected monitor

Is there an autostart script that will run if LE doesn't detect a monitor?
