I'm not sure where to put this, but it does have elements of Photon as phlib is the (apparent) problem.  I am using 6.4.
1.  I bought a new monitor that is 1920x1200 native and thought the Radeon 7000 card would support it.  Maybe.

The card supports up to 1600x1200 @ 60 hz, but the monitor does not.  I know because I tried.  First, I added a custom 
resolution of 1920x1200 (an option in phlip for the radeon driver) but the monitor was not happy.  Then I tried 
1600x1200, but no joy.  Then I tried 1920x1200 again.  Again blank.  But when phlip went back to 1600x1200 (which I 
expected to again look funky), I was in a clean 1920x1200 mode.  Joy.  Until later when I rebooted and the monitor was 
again blank.  So, the board will handle the resolution in a way that makes the monitor happy, but how to get there.  I 
tried adding a 1920x1200 line to the crtc-settings file and it almost works.  Some jitter and missing pixel lines in the
 middle of the screen, but generally good.  I don't know all of the settings, which is leading up to my question.

phlip, with the same board, under 6.3.2 shows support for 1920x1200.  But not under 6.4.1, so does anybody know the 
correct crtc-settings entry for 1920x1200 @ 60hz for the Radeon 7000 (is 1920x1200 @ 60hz a standard with common timing 
across most boards/monitors?)?

I tried:

pclock=15400          (from the monitor user manual)
hpol=1
vpol=1
htotal=2565
hblank_start=1900
hblank_len-665
hsync_start=2000  ?
hsync_len=224  ?
vtotal=1250
vblank_start=1200
vblank_len=50
vsync_start=1201
vsync_len=3

I am most suspicious of the '?' items which I just made up (as fairly reasonable), but any of the settings might be ...

Thanks for any help,

PS: I would switch cards if there are known solutions for supported cards on QNX 6.4.1 that work native with 1920x1200. 
 Better hardware is always a possibility.
