Limited resolution in 1080p25 instead of 1080p60 on my new tv

Zigou45

Hello, I have a problem since my change of TV (4K LCD to 4K OLED) my BATOCERA system which is based on a NUC Ghost canyon with a GTX 1060 worked perfectly in 1080p60 on my previous TV but now impossible to do better than 1080p25 and it is frankly unplayable and I’m not talking about the fluidity of the interface … The nvidia driver is obviously activated. I tried to force the frequency to 60 Hz by editing the file / usr / bin / emulationstation-standalone but I had a black screen while my tv showed 1080p60 … Do you have any idea? Thank you

Batocera should be using the highest refresh rate for that resolution, so maybe your TV is (falsely) telling your machine that it can’t support higher refresh rates? It could also be a driver issue, have you tried with the regular ones instead of Nvidia’s drivers?

You can manually test different modes with batocera-resolution setMode <MODE> btw, no reset required.

Thx for your reply. I tried the regular driver instead of nvidia and batocera run ok at 1080p60 (with terrible performance in ps2…normal).

I also tried the command batocera-resolution setMode 1080p 60 in xterm and it also work with nvidia driver.

So now i tried to definitively set this resolution and refresh rate. I manually set my output resolution by utilizing a custom boot script :

#!/bin/bash

if test -z “${DISPLAY}”

then export DISPLAY=:0.0

## Manually set resolution

xrandr –output HDMI-0 –mode 1920×1080 –rate 60

and placed in /userdata/system but There are no effects. Always stuck at 1080p25 after a reboot. I don’t understand…

Well… my best guess is buggy Nvidia drivers. Not much to do except to complain to Nvidia about it? They’ve never really prioritised their Linux drivers that well…
Outside of trying what you already have tried, the further things to do would be setting up a custom modeline or editing the display profile, which are both way too advanced for the average user to have to deal with just because of buggy drivers. You can see these methods mentioned in the CRT guide on the wiki and the respectively troubleshooting page: https://wiki.batocera.org/display_issues
