Hello

After a successful remote desktop login, on the host I can now no longer detect the 2nd monitor. Screen resolution on remaining monitor is off, it's gone over to use Microsoft Basic Display Adapter even though it was using the correct adapter previously. Both previously working display adapters now show Code 12 error: "this device cannot find enough free resources that it can use". The system has also become very slow, when I right-click the desktop, it takes up to 30 sec for the menu to appear. Anyone had a problem like this? I have restarted the computer several times, reverted system to a working state last week, done another successful remote desktop login/logout from my laptop to this computer.

Windows 8.1 Pro

Displays: Dell U2412M

Intel R HD Graphics 4600

Thank you in advance for any help/tips to help solve this problem!

This error message can also appear if the BIOS did not allocate enough resources to the device, I want to know how much RAM do you have on your computer, because the Display Adapter calls for extra RAM to run the monitor.

If you dont have enough RAM to allocate, the monitor wont start, thats why the computer becomes very slow.

Here I suggest a possible solution:

Adjust the amount of memory dedicated to video/graphics.  You can change that in BIOS. there might be an option in your PC's BIOS that lets you change the amount of system memory used for video/graphics.  

You'll just need to find it in the BIOS, the BIOS options in the Advanced settings, the option varies depends on the BIOS version you can set the maximum memory that it can take to a lowest value.

Regards
