screen blinks

[Valentin]

I am tired of constant problems with my computer.

Once every 2-3 minutes the screen blinks for 1 second.

Drivers are all updated. It was from the beginning. Just before it was once in 30-60 minutes, now very often.

I have windows 10.

Connection via displayport. Blinks when connected via mini displayport / usb type c.

Hi @Valentin​ 

Your NUC works with DP 1.2 video standard. Please ensure that in your monitors in the DP video input settings DisplayPort 1.2 option is enabled.

1. For LG 32UD59 see page 23 of Owner's Manual: https://www.lg.com/us/support-product/lg-32UD59-B
2. For LG 27UK650W see page 26 of Owner's Manual: https://www.lg.com/us/support-product/lg-27UK650-W

Hope this will help

Note:

You should used DP 1.2 certified video cable.

You may also try HDMI connection with High Speed HDMI cable.

Did you check that DP 1.2 is enabled in your monitor?

DP 1.2 on

[Valentin]

I tried 3 different cables. Flicker at all. through hdmi everything is fine. But I always have 2 monitors connected. and through hdmi 4840 * 2160 24HZ, you need 60HZ, which allows only DP

[Valentin]

I connected the NUC through 2 original display port LG, connected via the displayport / minidisplayport cable, connected through the minidisplayport and thunderbolt adapters. With this connection, there were flickers on both displays. Flicker was not only when connect HDMI.

[Valentin]

I managed to solve the problem. While flicker is not observed.

If one monitor is connected via displayport, and the second via hdmi, then on the second one it is necessary to turn off displayport 1.2. I suffered 4 months.

[Valentin]

today turned on the computer, it all started on a new one. It has become as before flicker and even more.

Hi @Valentin​ 

I can't answer to this question since I'm not from Intel. I'm user like you are. First, this question you should address to the place where you bought your NUC. The next choose is to ask Intel Service Support for replace your NUC, since it is covered by 3 years of International warranty. You should issue support ticket: https://supporttickets.intel.com/servicecenter?lang=ru-RU, but I think that better is phone nearest service support: https://www.intel.com/content/www/ru/ru/support/contact-support/emea-contact.html?_ga=2.222412187.1693300338.1547408208-141640707.1541197774&erpm_id=2998540 .
