Helloooooooo..

Anyone had two displays attached to their IBM Power 5 with a GXT135P Graphics adapter? (working.. not just attached)

It does have two outputs,, but would like some knowledge that it will work before I move the beast into position.

AIX 7 BTW.

TA!!

Should work, but don't know for certain (the POWER6 has a GXT145 and it's 6.1).

First post! (I will introduce myself tomorrow)

285, GXT135P, AIX 7.1 myself. Reviving the old dead post.

I don't think it will work, according to the specifications:
http://ps-2.kev009.com/rs6000/rs6000_ps ... XT135P.pdf

One or two monitors (identical image) supported at resolutions:
640x480at60Hz
1024x768at60-85Hz
1280x1024at60-85Hz
One monitor supported at resolutions:
1600x1200at75-85Hz
2048x1536at60-75Hz

There is no reason for the supported resolutions to be different if only mirroring is taking place.

I know it's weird but it's true, and confirmed by many IBM documents.
To use 1920x1200, like I'm using now, I need to go for VGA. On DVI it tops at 1280x1024@60Hz or 1600x1200@30Hz. I have no idea why.

Edit: The DVI limitation is there even if you have a single monitor connected.
