Occasional Monitor Glitches or Distortions Reported
You're dealing with a recurring flickering problem on your second monitor, particularly under demanding tasks. Here are some possible points to consider: The issue might be linked to the monitor's power delivery or cable quality, especially with varying brightness settings. The artifacts you mention could indicate a display calibration problem or a hardware fault. Trying to resolve it by changing cables or resetting drivers is a good start, but if the problem persists across monitor positions, it may require checking the display's internal components or consulting HP support for model-specific guidance.
You confirmed the changes to both monitors and the graphics card connections.
I changed the monitors myself, but the problem remained with the "second monitor." I also purchased brand new cables. I'm using a NUCX i7 from Minisforum (RTX3070). It only has one HDMI out, and the rest is Thunderbolt. I'm forced to use a Thunderbolt to HDMI cable. I also replaced that one for a shorter cable, but it didn't solve anything. Perhaps a USB-A graphics adapter would work better for the second monitor.
No problem, I'm glad you're okay with any input. It seems the port is functioning well, since I also use it for my external SSD to transfer large amounts of data. Now that you mentioned this, I might try a USB-A to HDMI graphics adapter to check if the issue gets fixed. I don't rely on my second monitor for gaming anyway.
Essentially everything is handled by the CPU, and the amount of processing can rise a lot depending on your setup. Regarding the Thunderbolt connection, you might find it easier to use a basic USB hub and connect a cable instead of dealing with direct Thunderbolt-to-X cables, which have caused problems before.
I reviewed your monitors and noticed they also support DisplayPort. There could be another reason to avoid it. Thunderbolt includes DisplayPort directly, which may offer a more reliable link with a TB3 to DP adapter. USB A to HDMI will function as well. A Thunderbolt-to-HDMI connection over USB C should also be possible.
This is actually a very good point. That way I also don't have to unplug the 2nd monitor when using the SSD. Thank you for that tip!
