CRT tv has vertical scroll only at288 resolution at 51hz.

(1/1)

Dorthensensens:
One of my crts cannot play games like Pac-Man when switchres tries to use anythingx288 for resolution without having a scrolling sync problem. It’s only on my 20” tv. Is there a way I can force the resolution to use something else?  Or is there some other solution that would be better?  Thank you

pakoman:
Maybe you can use 280 lines and crop 4 lines up and down ?

Would increase the hz too.

Or as it seems you have several screens, why not rotating the TV and use the native resolution for vertical games?

Dorthensensens:
Thank you for the reply. When you say to crop some of the lines, are you referring to changing crt emu driver settings?  I was playing around with the monitor defaults but I’m afraid of breaking things. Any advice on how to properly do so will be appreciated.


And yes if I turn it side ways it works perfectly except this tv is in a fixed arcade cabinet running multiple duties to play various landscape and portrait games. Donkey kong for example works fine. It’s only resolutions like Pac-Man that cause me an issue on that specific tv.
