I have an intel nuc5i5ryk connected to a 2560x1440 monitor. The connection is made via HDMI cable (ver 1.4) and the nuc has installed the latest 0249 bios version.
The problem is that the screen at POST process and BIOS menu blinks and the has randomly color underscores _ all over the screen.
The screen turns black and back again all the time and I can't work to the BIOS menu. This happens only at full resolution 2560x1440.
There is no blink problem with a 1920x1200 monitor via mini hdmi. I have allready tested it.
Please reproduce the problem with a higher than HD resolution monitor. And consider fixing it at near future.
