When I connect any device through minidisplayport-to-VGA adapter that screen flickers when content is refreshing - if there is static picture (i.e. desktop) everything is fine.
I thought OK, chinese noname adapter causes this, so I went and bought genuine Apple miniDP-to-VGA adapter and problem is here.
What I have tried to determine/solve this problem:
- I have now 3 adapters - chinese noname, Apple and Blitz (marked as supported for NUC here on Intel web) one
- I have 7 different VGA cables (shielded/unshielded, different lenghts, gold plated contacts,..)
- I have two same NUCs (same model, same amount of RAM, same SSD, same BIOS config) - both units are using latest BIOS and drivers
- I have 3 different monitors and one projector
I tried all possible combinations with both NUC devices and everytime screen was flickering BUT I when I use one of these adapters to connect my rMBP (Early 2013) to monitor/projector everything runs as expected - no flickering.
I found here on Intel forums that some NUCs had problems with screen flickering on HDMI output - this was solved by new BIOS.
From what I tried, I found that has to be NUC issue, maybe HW, maybe SW. What the heck, so I took one NUC and went to store, send it to service and they gave new one (however no issue was found) - same problem, screen flickers!
So this has to be BIOS issue, right?
Has anyone same issues?
Please Intel, investigate and fix this. It`s pretty annoying.
