Dual Monitor Setup Suddenly Stopped Working


New Member
I have two Samsung CFG2470's, and an H50. Two days ago, without any specific cause, My machine suddenly stopped allowing dual display. Each monitor and cable have been tested rigorously. 1 is on DP the other HDMI. I can use one, or the other, but not both. Neither Windows 10 nor 11 detect the second monitor.

Any ideas?

Please try the following
1. If you use dual-screen display, it is recommended that you use two different types of monitors to connect
2. Press the DEL key repeatedly when starting up, modify and increase the display memory.
3. Update the display driver.
