Dual monitor support enabled by default


Recommended Posts

Posted

Hello,

Ik have an unattended installation with all the drivers for my system.

But after Windows is installed and booted, the secondary monitor is enabled by default.

I want it to be disabled by default.

Can anybody help me with this problem?

My graphic card is a Radeon 9800XT and I use the latest Catalyst drivers.

Thnx!

I'm pretty sure the setting is in the registry. :)

Indeed.

Use RegSnap/RegShot...

1. Enablee your 2nd monitor.

2. Run RegSnap/RegShot for the first time.

3. Disable your 2nd monitor.

4. Run RegSnap/RegShot for the second time.

5. Let RegSnap/RegShot compare the two registries and voila, there is the key you need.

Yep, Regshot shows 20 modifications on turning the 2nd display off and 11 on turning it back on (I use 9600XT), all in HKLM\SYSTEM\.

Some are duplicates in the registry.
