Title: Sharp Image 639DS-R Dual Sync CRT use with GroovyMame/EmuDriver
Post by: AstroSonic65 on July 15, 2023, 12:15:30 am

Hello

I have 39” Sharp Image CRT that is capable of running at 15khz or 25khz.  I’m in the process of configuring CRT EmuDriver and was curious if it would work better using one setting over the other.  The jumper is currently set to 15khz.  The vast majority of the games I’ll be playing are from the eighties.

Thank you,

crt_emudriver can be set up to deliver either 15kHz or 25kHz pretty much equally well. However, it's best to display games at native res. Most 80's arcade games were 15kHz.

25kHz is medium res, which apart from Sega Model 2 and Model 3 games is pretty obscure.

Thank you for your response, I appreciate it very much.
