Problem with HDMI output to TV

shuston1981 · February 15, 2017 at 7:55 PM

I recently installed LE onto an older HP laptop. When I plug the HDMI cord into the TV it only displays in the top left corner of the TV screen. I found an earlier post suggesting that I check the box to "blank other screens" and then switch the output to HDMI1. However, when I do this both screens go blank and I have to restart the computer. I have used this computer before with Kodi installed on windows and it worked fine on the same TV. Any suggestions?

an older HP laptop... Can you please be a little less vague on the tech details of your hardware?

Try using SSH to log into your laptop when running LibreELEC and your TV connected.
Give us the returned URLs from the following commands:

Code

dmesg | pastebinit
xrandr | pastebinit

I have exactly the same issue. I'm running an Acer laptop which has a celeron CPU. It's working really well and very quick however when connected to the TV through hdmi the Acer logo is across the full TV screen, but then kodi is only in the left hand corner.
I cannot login through ssh but can access through file explorer on my windows laptop.

and you have also the same problem, if you select "blank other displays" that everything is black after?

Please provide the same things Klojum already asked for in the posting above.

Thank you for your responses. The laptop is a HP Pavilion with the following specs:
GPU: Mesa DRI Mobile Intel GM45 Express Chipset
CPU: Pentium Dual-Core CPU T4300 @ 2.10GHz

I also logged in through SSH and received the following URLs:

OK so mine got solved. If I blank other displays , then then go to video calibration and escape back out, it resides to full screen on the tv.

If your goal is to have the video output to the TV with the laptop screen disabled then SSH and try this below.

Code

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

Code

echo "xrandr --output LVDS1 --off && xrandr --output HDMI1 --mode 1920x1080 --rate 60.00" >> /storage/.config/autostart.sh

If you need to go back just delete the "autostart.sh" file created.

Worked Perfectly! Thanks!
