Re: framebuffer refresh

One of the big challenges can be whether a given monitor supports sync-on-green.  I Googled and once found a list of LCDs that had been tested and found to support SOG.  Both my Sun and SGI systems require this, which is why I did the digging -- Ian

Sun output on a LCD display can be problematic. Its important to check the resolutions that
the LCD display will support carefully - this usually means digging through the data sheets.

Some of the older LCD panels do support 1152x900x66, I found a LCD display some years ago
that supported this resolution and use it with my Sun 3/80.

In general modern LCD monitors dont seem to sync in the same was as the older multi-sync
monitors which would 'have a go' at most input, and with some adjustment would give a
stable image.

Another advantage of old style monitors, was that they would up scale lower resolutions to
full screen and still give a resonable image in most cases.

I still keep a couple of nice multi-sync colour monitors around just in case :)
