Matrox G450 refresh ranges

guys,
I’m trying to get my Matrox g450 configured under the newest (Jan18 )
qnxRTP. Whenever it I use phgraphx to set the up my card using the matroxg
driver instead of the vesa driver my monitor quickly displays an out of
range message. My monitor supports vertical refresh of 85Hz at 1600x1200
and I’m only trying for 60Hz at 1024x768. It may be that the program is
setting the horizontal refresh too high but I see no option to change that.
Any help would be greatlky appreciated.
Thanks

I have a similar problem, in that my display will work with the correct
drivers at the appropriate vertical refresh (1152x864x32 R75) but the
horizontal refresh rate could do with some tweaking… as it seems to be
scanning over to the left. (No matter what bit depth i run it in, but only
at that resolution)
I run the same settings under windoze, and had previously run the same under
linux, but that gave me options to alter the position to overcome the
problem. So far, this is the only thing that is annoying me about QNX :slight_smile:
Cheers.

Hi Kaiton,
