AMD Catalyst Driver Version, and Driver History
- 13.6 Beta 2 => problem
- 13.4 => problem
- Windows default driver => works fine
- Windows 7 Professional x64
First choose in Windows energy saving settings to shutdown the monitor after a minute for testing the standby.
My old monitor was directly connected via DVI cable, because both monitor and graphics card (HD6870) had this port and HDMI port of the card is needed for TV connection. With this setup standby mode worked without problems.
I changed monitor and graphics card and the new monitor has no DVI port. I first connected it directly via HDMI cable to the card and there are also no problems with standby. But as I already said: I need the HDMI port of the card for the TV connection. The new graphics card came with a DVI-to-HDMI-adapter, so I connected the DVI cable I used with the old monitor to the card and at the other end to the adapter cable which is plugged into the monitor.
The monitor also enters standby mode like with the other setups, but as soon as I move the mouse to leave, the PC freezes. (I can see it on the clock of the Logitech G510 display and the not changing numpad-LED) Only way is to do a reset.
This problem only occurs if I have the Catalyst driver installed. With default Windows graphics driver it works fine. I also tried only installing Catalyst graphics driver, without the other software included in the setup => same problem. So this must be a problem of the driver itself.
Please help me fix this, so I can use DVI. I've also read, that ZeroCorePower won't work, when using a HDMI cable. This means for me: more energy consumption (without standby & ZCP).
