[Fix] Windows 11 is slow and freezing after adding a second monitor

Issue: Hello. My Windows 11 acts up. It slows down and starts freezing after I hook up my monitor to the computer. I use the laptop, and when I work, I want to have an additional display. But this issue keeps me from using the computer normally. Is it possible that the monitor additional slows down the PC so much? I guess it should not be an issue. Can you help me?

Solved Answer

Windows 11 is slow, and freezing after adding a second monitor or ransom performance issues can be a common problem with the newest version of the Windows operating system. This OS was only available for the insider program for a while, so issues can be common if the system is not properly installed and upgraded.[1]

Users can encounter these issues due to the unsustainable resolutions when the low-end GPU is not capable enough to handle the resolution that is required to enforce. You can resolve these issues if you bring the screen resolution down. The issue with the ransom freezing can be related to incompatible drivers or insufficient VRAM too.

This issue is commonly reported by users[2] that have been annoyed by this system performance problem that keeps the machine from smooth running. Windows 11 is slow and freezing after adding a second monitor unexpectedly and can indicate some power adapter bugs, conflicts with other programs, or outdated BIOs or vBIOS versions.

Don’t pay ransomware authors – use alternative data recovery options

Malware attacks, particularly ransomware, are by far the biggest danger to your pictures, videos, work, or school files. Since cybercriminals use a robust encryption algorithm to lock data, it can no longer be used until a ransom in bitcoin is paid. Instead of paying hackers, you should first try to use alternative recovery methods that could help you to retrieve at least some portion of the lost data. Otherwise, you could also lose your money, along with the files. One of the best tools that could restore at least some of the encrypted files –  Data Recovery Pro.
