Just to clarify, you mean phgrafx, not phlip, correct?

Subject: 1920x1200 on ATI Radeon 7000

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,

Terry Laughlin

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.

pclock=15400 pixel clock is to low for 1920x1200 video mode, try 186620.
hblank_start=1900 also is not correct, it must be 1920.

Try these settings:

xres=1920
yres=1200
refresh=60
pclock=186620
hpol=1
vpol=1
htotal=2498
hblank_start=1920
hblank_len=577
hsync_start=2007
hsync_len=200
vtotal=1242
vblank_start=1200
vblank_len=41
vsync_start=1216
vsync_len=3
