I have used the AMD Radeon HD 7950 for 5 years now to support my 4 monitors in my music studio.
All of a sudden it can only run 3 monitors now. All monitors work and I have switched connections on the back on the Mac, so it doesn't matter which monitors are plugged in. It will still only choose 3 monitors.
How can I fix this?
Thank you for any advice and help!
