I have a 1024x768 LCD screen which I have connected to a KVM and then to a mac via a 10 switch vga-dongly-adapter..
Out of curiosity I tried using 512x384 mode and it came out crystal clear on the LCD screen. The other great thing is it's a simple multiple in both directions so doesn't look stretched.
The good thing is it means I don't have to find more VRAM to have more colours, just kick down to 512x384!

What kind of LCD monitor is this?
It's a "CyberHome TV/Monitor", so it will do PAL TV frequencies as well.What kind of LCD monitor is this?
Normal VGA CRT's collapse in a heap when given 512x384, but I was most surprised and impressed.
What Mac is driving it? What refresh rates (vertical and horizontal) is it pushing?
A Q700, I will get round to testing my LC-II and LC-IIIs.What Mac is driving it? What refresh rates (vertical and horizontal) is it pushing?
That refresh rate info would be handy too, if you can track it down.

The screen may be able to tell you in the OSD, that may be the quickest way to figure it out.

The Monitors control panel should tell you. You might have to tick the box to show all possible settings and not just the recommended ones. OTOH, ISTR that LCDs are all fixed frequency ...
But the computer doesn't know that, it thinks it's an old Apple 512x384 colour screen.
I do know that if you try and drive the screen 1024x768 with anything other than 70hz the picture refuses to lock properly.

I'll put my money on 60Hz.
