Forums -> UltraMon™ -> 3rd monitor won't go to sleep when disabling secondary and stays blank
Cycronexium   2009-06-04 15:49
Hello here is my rig

Intel i7 920 6GB RAM, running Vista 64x
GeForce 9800GT Pcie: 1) Main Monitor 2) Unused
GeForce 9800GT Pcie: 3) Sec Mon 4) Third Mon

Here is my issue. I'm using trial of beta 3.0.5 and in some occations (like when I'm gaming) I like to disable the secondary monitors. I have noticed that when I do this the 3rd monitor (which is the second one on the second card) only goes blank and doesn't go to sleep.

If I leave my desk and come back later I see that all the monitors are in sleep mode except the third monitor who's still open and blank.

I have tried to disable the monitors from Display Settings, actions with same results.

If I let all monitors enabled they will ALL go to sleep correctly at the same time.

I have even tried to create a display profile with only 1 monitor and I get the same result.

1 small precision: I am using the x64 version of the software.

and I have played around with the DisableEnableMonitor script and if I disable monitor 3 it does go to sleep... if after that I disable monitor 2 it GOES BLANK...

so in other terms I don't think its hardware.

i'm at a lost here...

Here's more info:

I have tried rebooting, no changes

If I disble the monitor with window's display settings the monitor does go to sleep..

Sounds like a display driver issue, what happens if you disable both secondary monitors via Windows Display Properties?

You are right, if I disable both I have the same problem... great cool thank you it gives me a trail to follow and it removes UltraMon from the equation..

Were you able to find any solution to this Cycronexium? I just ran into the exact same problem. I am using NVIDIA 8800 GTS. I have a GTX 260 I might try it on but since they use the same driver I suspect the same problem will occur.
