![]() ![]() The only way I could get out of the black screen was to press the power button to shut down. I ran the System File Checker, chkdsk /r, and DISM scan – all was fine. I adjusted the Windows power options so that the monitor never turns off and the PC never sleeps. I double-checked the cable connections, replaced the monitor-to-PC cable, and used another monitor. The PC developed an unusual and intermittent problem where the monitor goes black/blank and stays black when I sign/log off from any of my user accounts. I was running Windows 10 version 1909 on a fairly new desktop PC that is used infrequently and has only a few extra software installed on it. I had a recent experience with my 4-year old PC monitor suffering the black screen of death. If you can live with a not-as-bright display, it may even lengthen the life of this monitor.īut if that’s not an acceptable option to you or you continue to experience problems, this may be an excuse to get yourself a brand new monitor. This may reduce how often your screen goes dark. One simple fix may be to reduce the brightness of your monitor. That said, my research seems to indicate that some of the components in your monitor could be stressed, resulting in this symptom. Monitor quality is also probably pretty important to you. To me, that says you’re doing some visually intensive tasks. In your question, you mentioned that you’re doing graphics and video work. If that’s the case, then the problem is with the original monitor. I suspect that you won’t see this on the new monitor. Once plugged in, do what you normally do and see if the screen ever goes dark. It doesn’t have to be the best monitor you just need it long enough to connect to your HP computer for a while. If you don’t have an extra one from another machine, borrow one from a friend. It’s not likely that this is an issue related to the computer itself, but you can rule that out easily by simply plugging in another monitor. Make sure the cables are properly and securely connected. ![]() Just jiggling the cable a bit might cause an intermittent connection, which causes the screen to go dark. Sometimes, a monitor blackout can be as simple as a loose cable between your computer and its monitor. Let’s start by getting some of the obvious things out of the way. After doing some research, I have a couple of ideas. I have a similar problem with my machine. Your HP is a desktop model, which means you have a separate monitor. ![]() Please let me know if you have any further questions or if you would like me to clarify anything.A screen going dark isn’t likely to be a computer problem it’s probably a monitor problem. You have ruled everything else out and it looks like the LCD is your issue. I never like to recommend spending money but I think it's your only option in this case. Sorry friend, my suggestion is to purchase another as repair would cost you more than the hardware is worth. I personally think it has hardware failure. If you have plugged in a different monitor than the one giving you problems and everything is fine, then that tells you that there is something wrong with the monitor. Sadly if your LCD is four years old it is probably out of warranty coverage. The LCD seems fine for a minute and then goes black or displays very faint, dark text and images. I have encountered a few which did the same thing as you explain. It sounds like the backlight within the LCD is about to die. However, if that cable worked when you plugged in the other monitor then it is extremely unlikely that this is the cause. ![]()
