Vertical Refresh Rate on 19" Eizo TFT

Postby Storm82 » Sun Apr 15, 2018 2:32 pm

I've got a 19" Eizo S1921 TFT for use with MiSTer and it works most of the time perfect via DVI to HDMI-cable.

But on some cores the TFT doesn't like the vertical refresh rate. One example is the C64 Core. It shows 50.2 Hz or something.

Is there anything you can do about this issue?

The native resolution of the TFT is 1280x1024.

What settings you use in MiSTer.ini?
It seems you've enabled vsync_adjust option. You need to understand this option produces non-standard refresh rates. And as you already see, your monitor doesn't like either non-standard pixel clocks or non-standard refresh rates.

You're right!

vsync-adjust was enabled. I will try it with the option disabled as soon as I get home.

Thanks!
