NUC8i7BEH + UHD dual monitor >> HDMI port noise issues

Hi

I use NUC8i7BEH and UHD dual monitor(same model).

first monitor is connect ctype to hdmi, second monitor is hdmi to hdmi. problem is occurs in second monitor(hdmi). I tested monitor change case. too.

I use 1~2 movie and webpage, filemanger.

hdmi monitor show below ​symptoms.

  1. screen pixel noise (likely dad some pixel)
  2. screen line noise (green line)
  3. lcd off/on
  4. full screen noise (red.white.yellow's likely old tv)
  5. block blink

​first I know it is monitor problem, I change by same other monitor.

but It show same issue, and It only occurs connected by hdmi.

 

It seems that noise is generated when you use a lot of memory.

Current bios version is 66. It only can setup graphic memory max. 1G.

but current website's latest version is 51. last version 2 is removed. and I can't downgrade to 51. it failed.

Please check to support UHD dual monitor.

 

Thanks.​

  1. Usually problem caused by poor quality HDMI cable. Try to use Hi Speed HDMI cable like this one: https://www.amazon.com/Cable-Ultra-Compatible-FullHD-KabelDirekt/dp/B07CMFHJVQ/ref=sr_1_3?keywords=h...
  2. Verify that your Windows is updated to version 1809.
  3. Update drivers and bios: https://downloadcenter.intel.com/product/126140/Intel-NUC-Kit-NUC8i7BEH
