Ryzen 5 Pro 4650G 2k resolution

Hello. I have a Ryzen 5 Pro 4650G processor and a 2560x1440 monitor. No discrette videocard.
As soon as I install the AMD video driver, the image disappears, and the monitor goes into sleep mode.
After removing the driver, using the DDU, and before installing the driver, everything works correctly again.
Obviously the problem is with the driver. I ask for help, I want to fix the situation.

Re: Ryzen 5 Pro 4650G 2k resolution

Is the system stopping working? Or is the system not showing display output?

Could you first test the system with a HDMI-TV? If the system works with a HDMI-TV, the problem may be due to the display output and it may be necessary to try a different display port or a different cable.
Edit: What is your motherboard? Is the BIOS up to date?

v1.4 BIOS update is available for you. You may want to try this out. Frankly, I would like to point out that if the BIOS update is not done properly, your system may be damaged. It is necessary to try the system with a different TV or monitor. You need to find the cause of the problem.

Re: Ryzen 5 Pro 4650G 2k resolution

v1.4 was available for me when I went to the BIOS support page of your motherboard. Since you have a4/ac version motherboard, I think the update is not ready yet for you. BIOS update is already risky. For this reason, you should first try the system with a different monitor and TV, I think. If the BIOS update is left incomplete, the system may not boot at all.
