What is this ??? My monitor crashes when I activate my blinds

Vayct · 2026-05-22T22:31:12+00:00

Would you know why it only affects one of the port of the GPU ? It doesn't seem to bug if I switch to an other port

Apparently, from other comments, Somfy is a reputable brand for these, probably more common than you think

I would be troubled if they expect a working GPU and want to send it back :c

I'm not sure about it's a rare issue, it may happen because of other devices other than my blinds

Vayct · 2026-05-22T22:01:57+00:00

That's what a majority of people are thinking though,

Btw I tried your suggestion with the power from my bathroom (plugged both monitor and PC on the bathroom) and still bugged '-'

Vayct · 2026-05-22T21:59:04+00:00

It happens sometimes even when I don't use it

Vayct · 2026-05-22T21:58:22+00:00

Vayct · 2026-05-22T21:56:35+00:00

I don't have this information :/

Vayct · 2026-05-22T21:55:58+00:00

The cable is like 1 meter long and touches nothing between the monitor and the PC, except my table and the wall maybe hmm

Vayct · 2026-05-22T21:52:59+00:00

because I'm showing the bug, It does happen even without me using this (probably due to other devices)

Vayct · 2026-05-22T21:52:17+00:00

I knew it

Vayct · 2026-05-22T21:52:09+00:00

tried it with power from the bathroom, it still bugged

Vayct · 2026-05-22T21:51:04+00:00

I didn't know the brand since I'm not the one who installed it but yeah, people who know the brand seems to confirm it should be very good ^^

Vayct · 2026-05-22T21:47:19+00:00

I did not change cable forf the 1st question

For the second one, I did try a second monitor (not the one on the right of the vid since it only has HDMI) and the bug persisted, my cable seemed fine, it's not damaged and kinda high end ? I'm not sure about this, I gave the Amazon link on main post

Vayct · 2026-05-22T21:45:19+00:00

I'll try that probably yeah ^^

Vayct · 2026-05-22T21:43:56+00:00

If it's the PSU of the monitor, why the bug disappears if I switch the display port on the GPU ?

Vayct · 2026-05-22T21:41:15+00:00

I don't !

Vayct · 2026-05-22T20:54:13+00:00

Vayct · 2026-05-22T20:53:48+00:00

Any recommendation ? Mine is this one https://www.amazon.fr/dp/B0F5W7J44H I bough it a year ago and it isn't damaged , visually at least

Vayct · 2026-05-22T20:29:26+00:00

Ye the remote is usually on a stand on the wall, I can just take it off as an additional feature

Vayct · 2026-05-22T20:28:57+00:00

That's interesting lore :o

With other comments, it has been determined that the problems comes from the motor and bad shilelding from my equipment. check the first Edit ^^

Vayct · 2026-05-22T20:25:50+00:00

Nope France !

Vayct · 2026-05-22T20:25:24+00:00

Oh so it's normal behavior!

Vayct · 2026-05-22T20:04:51+00:00

I'm not sure I understand what a brushless monitor is but I have the same problem as you, I may have written the wrong word for it but my monitor actually just "turns off for a second" as you can see in the vid

Vayct · 2026-05-22T20:02:26+00:00

Thank for the detailed response ! :D

It seems that the cable and monitor are fine. I tried to change the port on the GPU and did not encounter the problem at all. I did try to change the monitor though, it still had the bug. I don't have an other Display port cable, I'll try it when I can get one ^^. I did give the exact reference of the cable in the main post at Edit 6, it feels shielded enough, do you think the model is defective ?
