So like many others I'm having a number of problems with my NUC7I5BNH that doesn't resume from sleep properly and keeps freezing even when it's set to not sleep. First, here's my hardware:
Windows 10 x64 Pro running Creator's Update
PNY CS2030 240GB M.2 2280 PCIe NVMe Internal Solid State Drive (SSD) - (M280CS2030-240-RB)
1 x G.SKILL Ripjaws Series 8GB DDR4 2400 Model F4-2400C16S-8GRS
I've connected to two different displays that have both exhibited similar behavior
Vizio m55-C2 4k TV
CROSSOVER 324K UHD 32" 3840x2160 60Hz HDMI2.0 DP 4K LED Monitor
All drivers are up to date and I have updated the HDMI 2.0 firmware.
If I try to run at 3140x2160 @ 60Hz, the display flickers frequently, with it sometimes being so bad that the computer is completely unusable. Running KODI, NETFLIX, or even just some websites in Chrome seem to make the problem worse. The only thing that makes the flickering go away is if I go to 4k@30Hz or go down to 1080p at 60Hz. I am using amazon basics hdmi 2.0 cables that worked fine driving 4k@60Hz with my 5th generation NUC so I'm fairly certain it's not the cable.
In addition to the flickering issues, the computer would not wake either monitor when it resumed from sleep >50% of the time and had to be reset using the power button. As a temporary solution, I disabled sleep entirely and that seemed to fix the problem. HOWEVER, after upgrading the HDMI 2.0 firmware, I'm now seeing another similar problem but I have no idea what is going on. After the display is turned off after 10 minutes, it eventually powers off but the computer is set to never sleep. When I power on the TV again, >50% of the time, the computer has frozen. This is different than the previous behavior because before I could remotely login to the computer and restart it. Now it is completely unresponsive and can't even be pinged. It requires a hard reboot to get the computer to respond again. I have looked in the event viewer and can't figure out why the computer is crashing. There is an error message that says something like: "The previous system shutdown was unexpected." but gives no more information about the error. Again, this problem seems to have started happening after updating the HDMI firmware. Is there any way to check the current firmware version and is it possible the update went wrong somehow?
The only BIOS setting I have changed is disabling HDMI CEC (I can't remember if I enabled it in the first place or if it was on by default).
Please help! I am at a complete loss as to what else to do to fix this problem and, as it stands, the NUC is hardly usable.
