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. A screen going dark isn’t likely to be a computer problem it’s probably a monitor problem.
