Display refresh rate?

[da na]

An old TV I had, a Toshiba LCD from ~2003, plugged it into my computer and it says it supports 50, 59.949, 60, and 120 hz in Windows. (Mind this is connected thru VGA which can't support 120 hz.) But whenever I set it to anything other than 60, the display goes black. Just wondering why these modes are listed if they're not actually supported. Is it because VGA doesn't carry EDID or something? Thanks!

VGA does carry EDID. It also supports 120 Hz. It's an analog format, with no resolution/refresh limit, aside from the monitor & GPU capabilities.

 

Your cable likely isn't up to snuff for the resolution/refresh rate.

Ah thought the max was 1080 120, my bad. I'm using a HDMI to vga cable with the hdmi end in my laptop so don't know if that's the issue. Thanks!

This definitely is the issue. These adapters usually report an EDID of their own, regardless of what the monitor accepts.

Ah good to know. I've had issues with EDID on that cable before and thought it was VGA in general.
