lr-px68k 60hz output problem

mcabx0

I notice my Samsung TV all the 16 bit games graphics would clip and didn't look right. I did some research and found out that the PI only pushes 30hz. So I changed to 60 in the boot code and everything runs great except lr-px68k. I tried every video setting with no luck.

@mcabx0 I also noticed the screen tearing on the lr-px68k core the most. It was the reason for me to finally switch over to the KMS driver. The switch is easy, but there was some reconfiguring of some retropie settings necessary.
I'm just wondering: why was your RPi set to 30Hz output? That's not the standard setting. And the TV should be able to process 30Hz?

It is when your resolution is 4k :).

@ecto I should have been more specific with the TV specs. @mitu is correct it is a 4k big screen TV.

@mcabx0 I suggest you lower your resolution, 4k is too large for the Pi4 to handle when running a demanding emulator like the x68000 core. See the docs or just use the runcommand launch menu to set a lower resolution for the Sharp system.

@mitu thank you so much will give it a try
