Hello,
I have a problem with my computer; almost every time I start it, I get colored bands appearing. To remove them, I have to either disconnect and reconnect my DisplayPort cable 5-6 times or press CTRL + SHIFT + WINDOWS + B 3-4 times (which I believe reloads the graphics drivers).
It's quite frustrating since it's a new computer, the graphics card is an RTX 3070TI, and all my drivers are up to date.
I don't know if it's a defect in the graphics card, or maybe it's a fault with my DisplayPort cable or possibly my monitor (I can't test it on another monitor since I only have one).
If anyone who has had this problem could help me or even if someone thinks they know the reason for the issue, that would be really nice of you.
Thank you in advance
I am attaching photos of the "colored bands, pixels."

Hello!
When you unplug your cable, do you unplug it from the GPU side or the screen side?
On the GPU, have you tested another DisplayPort? If so and the same issue persists, try with another cable.
Does your GPU have an HDMI port?
What other ports are available on your screen?
Best regards-
Thank you for your response.
I unplug my DP cable either from the monitor or the GPU, I alternate but I don't feel like there is a significant impact in this regard.
Yes, I have already tried the other ports on my GPU, the same thing. I will try to buy a DisplayPort cable this week to see if that could be the problem.
It does indeed have an HDMI port, but I haven't tried it in HDMI, is HDMI less performant compared to DisplayPort or is it the same?
On my monitor, I only have one DisplayPort and three HDMI ports, my monitor is an Acer EI491CRP 49"
Best regards.
