So, I’ve got a completely fresh build here—everything was put together just today. I installed Windows 10 on it, using a Dell UltraSharp 24 monitor paired with a GTX1050Ti OC 4GB DDR5 LP graphics card. Everything is connected via a DisplayPort to DisplayPort cable. The issue is that every 15 to 20 minutes or so, the screen glitches out briefly. It’s almost like someone physically hit the monitor; the image just shatters into artifacts for a split second before snapping back to normal. On top of that, every once in a while, the screen will just go pitch black for a second, as if it's doing a sudden refresh, and then it comes right back to life. This seems to happen at pretty regular intervals. I'm wondering, what could be causing this? 🤔 Interestingly, before I even installed Windows 10, I left the computer running in the BIOS for about half a day, and I didn't run into any of these issues. That makes me suspect it might be a software thing related to Windows, though the OS isn't activated yet (I just used the official ISO image straight from Microsoft's website).

EDIT: If it's relevant, I've also been getting this error during Windows updates: (0x80070643)

It looks like someone literally smacked the monitor; the image just breaks or flickers wildly for a tiny fraction of a second and then snaps back to normal. On top of that, sometimes the whole screen just goes black for a moment, like it's doing an accidental refresh, before coming back to life perfectly fine. It happens at these weirdly consistent intervals. What could be causing this? 🤔 Before I installed Windows 10, I left the PC running in the BIOS for half a day and didn't see any of these issues.

The best way to figure this out is simple elimination. Try plugging your monitor into a different PC to see if the artifacts follow it, or try a different monitor on your current rig.
Could be a hardware failure.

Since the resolution in the BIOS is super low, you can't really use that as a benchmark.

Looking at what you described, it sounds like a hardware issue with the graphics processor itself, and honestly, the fact that the computer is shiny and new doesn't change that reality at all.

I'd suggest getting ready to snap some photos of those glitches whenever they pop up so you can take them back to the service center for a warranty claim; otherwise, if you were the one who put the build together, you should probably look into swapping out that graphics card.

DP cables can be pretty finicky with loose connections, maybe try using DVI/HDMI if you have the option

@John Cook72/">@@John Cook72 - thanks, I think I'll give that a shot.
@swiftowl7/">@@swiftowl7 - I went ahead and installed a fresh version of Windows 10, specifically the Home edition this time. All the updates went through without any issues, but I noticed those artifacts are still popping up, just much less frequently now. I'm currently trying to grab the latest NVIDIA drivers to see if that helps. Worst-case scenario, I'll just record what's happening and send it over to the repair shop.
@fadedorca66/">@@fadedorca66 - I might actually try using a DVI/VGA adapter since my monitor doesn't have an HDMI port. Just wondering, though—what's the actual difference between using DisplayPort versus a DVI/VGA connection? Will I lose any image quality if I go that route?

EDIT: So, even after updating the graphics drivers, the problem is still there... Is there some kind of GPU stress test I could run to push it a bit and see how it handles the load?

Follow-up: Try this—download the latest version of PerformanceTest 10 and run nothing but the 3D test. Use RealTemp to log the maximum GPU temperature during the process. Honestly, it might just be some weird issue with the monitor's internal electronics, who knows? You could also try plugging the PC into a TV to rule out a faulty monitor entirely.

Both DVI and DisplayPort act similarly, except DVI doesn't carry audio; both allow for two-way communication with the monitor. HDMI handles both video and audio, but lacks that return path.

You could also try running the GPU stress test in AIDA64 to see what happens.

VGA is an analog connection, so the GPU generates a numerical value that gets converted to analog before the cable, then back to digital after the cable and right before the panel hits the screen. It’s not that it won't produce a decent image, but digital values are inherently more precise when it comes to the actual pixels on the screen. With DVI, HDMI, or DisplayPort, you're getting a direct, precise numerical value for every pixel.

Alright, here’s what I managed to capture: https://ufile.io/vu8npg59

The issue seems way more noticeable during gaming or while watching videos—basically, whenever the GPU is under a heavy load. It happens constantly then. On the other hand, if I'm just doing something simple like typing in Microsoft Word, it only pops up maybe once every 20 minutes or so.

From what I can see in the video, it looks like your monitor isn't picking up the signal from the GPU. The screen just blacks out every now and then.
Maybe try dropping the refresh rate or switching to a lower resolution, just as a test.

I tried switching things up with a different DP to DP cable, but that actually made the signal drops even more frequent. My monitor just keeps cycling through "searching for DP signal" before eventually giving up and displaying "no DP signal from your device." For now, I've managed to get the laptop and monitor working okay by using a VGA to VGA cable, and it seems stable without cutting out. I've already sent the configuration over to the service center; since it started acting up right after I bought it, it’s still under warranty, so hopefully they can sort it out quickly.

My PC finally came back from the repair shop after testing, but the issue is still there: https://www.udrop.com/5jyK/WhatsApp_...t_07.39.17.mp4 What should my next move be? I'm wondering if there might be a connection issue between the monitor and the tower itself. Is there any real chance the monitor isn't actually the culprit here?

There's a version where it could be either one, but honestly, my money is on the monitor being the issue.

The best way to handle this is probably just grabbing another monitor to test things out, because if that works, then you know for sure the trouble lies with the connector or the PCB inside the monitor itself.
