On the Odroid-C2 connected to a Samsung LNT4661FX/XAC TV, the HDMI blink issue appears to be resolved after I changed the refresh rate in Kodi display settings from 60 fps to 59.94 fps. Perhaps the same change will resolve it for others experiencing the same issue.

Hello all,

I am new to the forum and it looks like I have the same issue.

With an odroid C2 running libreelec 8.2.5 and Kodi 17 (bought to play 4K videos), I encounter the same issue : from time to time, the image disappears for a few seconds. Most of the time, the sound remains even if I can lose 1 or 2 seconds. I cannot watch a full movie without issue and it happens as well when playing in libreelec menus.

My TV is a Samung UE50KU6000.

I am attaching a debug log just in case someone can help.

Pretty much the same exact setup here with the same symptoms. Any luck in resolving the blink issue? When it happens frequently, rebooting the odroid-c2 seems to help reduce the blinks significantly for a while, but they always return. Issue exists with both 8.2.5 and 9.0.1

I'm really surprised this didn't work"APPEND boot=LABEL=System morequiet disk=LABEL=Storage quiet setfbres=1080"
It worked here on the first try and has booted in fullscreen ever since.

I think the issue is that even when the splash screen is shown in my case, it is actually being shown at 1920x1080 (the TV confirms that while the splash screen is shown the display resolution is 1920x1080 60Hz) ... I have no idea why the splash image itself is being shown at 1024x768 in the top-left corner of the screen.

Thanks everyone for the suggestions. In the end none of the suggestions involving edits to autostart.sh, extlinux.conf, or syslinux.cfg worked in my case. I ended up creating an oemsplash.png file (attached) and placing it in /flash/ ... it's a hack workaround to my specific problem, but works quite well. It was a quick and dirty way to have the LibreELEC logo displayed in the exact centre of the screen with the correct image ratio.

I gave up trying to resolve the main issue of having the default boot splash image displayed at 1024x768 in the top-left corner of a 1920x1080 screen.

This should have done it.

Code

echo "xrandr --output DP3 --off && sleep 1 && xrandr --output HDMI2 --mode 1920x1080 --rate 60.00" >> /storage/.config/autostart.sh

Can you verify in your "autostart.sh" file if the line you see there correspond to that one?
You could have more than one line now or the one with"HDMI-2-0" would make it not work.

This should work also.

Code

echo "xrandr --output DP3 --off && xrandr --output HDMI2 --mode 1920x1080 --rate 60.00" >> /storage/.config/autostart.sh

The autostart.sh file is correct. I had even gone in there with nano to make sure there were no duplicated lines and that it was all correct. I know that the command is being run, since I experimented with different modes (e.g. 1280x720) to make sure it was having an effect and it was indeed having an effect on the GUI, but I have no idea if autostart is being executed before the splash screen is displayed, or if it is executed after.

try adding setfbres=1080 to the kernel append line in syslinux.cfg

I tried that and it didn't have an effect. Thanks for the suggestion.

You are right about the "HDMI2" i overlooked that, but from the picture you have in your first post it looks exactly like "1024x768" displayed on a "1920x1080" screen without stretching. And "1024x768" is the max resolution displayed on your "DP3" output which says is connected also(could be passthrough)but we don't have this information.
Can you confirm your tried this exactly in the same order?

Code

echo "#!/bin/sh" > /storage/.config/autostart.sh

Code

echo "xrandr --output DP3 --off && sleep 1 && xrandr --output HDMI2 --mode 1920x1080 --rate 60.00" >> /storage/.config/autostart.sh

Yes. I ran those commands in order and it does not have an effect. The autostart.sh file is correct. I can confirm that the issue is in fact related to DP3 and the resolution is 1024x768 when the splash screen is displayed.

I also found that if I set the Kodi display output to "Default" from settings, it defaults to having 1024x768 as the resolution, same as if DP3 is selected. So it looks like the "Default" setting for display output uses DP3 for some reason. If there is really a way to disable DP3 or to at least change the "Default" display output to be HDMI2, that would probably fix the issue.

You should have used (HDMI-2-0), also is there anything else connected to the PC(Display port)?

Try this:
xrandr --output DP3 --off && sleep 1 && xrandr --output HDMI-2-0 --mode 1920x1080 --rate 60.00

That also didn't fix it. There is nothing else connected to the PC and the only available output port is the single HDMI port.

I had to change --output back to HDMI2 as I received the following error:

# xrandr --output DP3 --off && sleep 1 && xrandr --output HDMI-2-0 --mode 1920x1080 --rate 60.00
warning: output HDMI-2-0 not found; ignoring

I have a similar issue. Mine depends on the fact that the splash screen is in a different resolution than the gui is after and my TV switches not fast enough. So there is simply no solution for me and, tbh, if the gui is fine, I don't care about a splash screen that is visible for 2 secs.

I believe that's the main issue too. The splash screen is being displayed at a different resolution than the GUI (my guess is 640x480 given the stretch factor and the relative size of the splash image). I thought perhaps there was a different setting somewhere for the display resolution when the splash image is displayed vs. when the GUI is displayed. Of course I can live with it, but it's just a bit annoying.

Try this, using your correct HDMI and refresh rate output(60.00); thread-4094-post-29712.html#pid29712
SSH your pc and type the following command "xrandr" this will give you the correct HDMI output name.

Tried and it didn't have any effect. The LibreELEC logo is still shrunken when the splash/boot screen is shown. It should be noted that the text that is displayed during bootup and shutdown appears to be normally sized on top of the splash image.

Here is the created "/storage/.config/autostart.sh":
[code=php]
#!/bin/sh
xrandr --output HDMI2 --mode 1920x1080 --rate 60.00
[/php]

And this is the output of "xrandr" command:

Which GPU is in your 'x86'? (We always love minimalistic details, you know...NOT).

Intel i3 Ivy Bridge desktop PC. Output via HDMI.

When booting up my x86 box running the latest LibreElec 7.95.1 (same thing happened with all 7.90.x versions), the boot or splash screen LibreElec logo is not shown in fullscreen, and is instead shown at about 1/3 the proper size aligned to the top-left of the screen as shown in the attached image. The LibreElec screen resolution is set to 1920x1080 @ 60Hz and this works fine. It's only the boot/splash screen that is shrunken. Any ideas how to resolve this?
