Is this the latest driver available for NUC7i7BNH ?:
No DCH driver available even though this is very recent Iris 650 graphics device ?
Generic Intel VGA DCH driver:
nor DCH driver dedicated to NUC devices (but this NUC device not listed as compatible with it):
do not want to install claiming they weren't tested on this hardware.
I once managed to forcibly install one of the previous releases of generic DCH drivers but results were weird. Initially it seemed to work but when I tried to play accelerated video (think Youtube but not limited to this), image was randomly dissapearing as if someone was unplugging and replugging HDMI cable for short time. I then returned to non-DCH driver dedicated to this NUC model and things returned to normal.
Seems like this device needs dedicated driver but DCH one wasn't released so far ?
Just because the latest dch driver was not tested on your hardware does not mean it will not work.
What is your focus on "VGA" driver?
Also, with HDMI, get a quality HDMI cable.
With VGA I meant Intel integrated graphics card in general (all are VGA-compatible anyway), not analog VGA output (which this NUC model doesn't have - it has HDMI 2.0 and Thunderbolt 3). I use HDMI 2.0 connection.
The generic DCH Intel driver not dedicated to this NUC model (NUC7i7BNH belongs to BN-series NUC aka Baby Canyon) just don't want to install. The installer says it wasn't tested with this device, contact hardware manufacturer for dedicated driver etc. You can click on OK only and then it exits.
Same happens with Intel NUC-dedicated DCH drivers for later NUC models.
As said, I managed to install generic Intel DCH driver (from the link you provided, I mentioned it in my initial post too) by uninstalling Intel-dedicated graphics driver for BN-series NUC first. When graphics card is claimed by Microsoft's generic graphics driver, then Intel's generic DCH driver installs just fine (no incompatibility messages).
But then you encounter the issue that I had mentioned before - during video playback, the screen randomly disappears/goes black which is very annoying.
That's not a hardware issue - if I return to Intel-dedicated non-DCH driver for this BN-series NUC (which is quite outdated now), then everything works fine.
I wonder if anyone has encountered the same problem and found a solution or are you still using Intel-dedicated old non-DCH driver with BN-series NUC devices.
I tried older generic DCH drivers with 1903 and at that time (half a year ago) I had this weird blinking screen behavior.
I have latest 0080 BIOS applied and latest LSPCON firmware 1.77.93 too.
Your positive results with generic DCH drivers tell me that I just have to give another try. I now have Win10 1909 and will try latrest DCH generic drivers.
So I tried various DCH drivers (generic 7463, generic 7584 and NUC-dedicated 7529 for newer NUC models) with this NUC7i7BNH and again same old issue - blinking screen while playing video.
They would only install if graphic card is claimed by Microsoft's generic driver (otherwise incompatibility error).
Desktop is OK with DCH drivers but when video is played, after a couple of minutes screen goes black randomly.
Once I returned to latest NUC BN-dedicated driver (6286), everything back to normal.
Intel must have good reason(s) while the still haven't released DCH driver dedicated/tested with Baby Canyon NUCs for so long and 'old' 6286 is still the 'official' one.
NUC7i7BNH is my current 'multimedia' PC.
I recently bought Bean Canyon NUC8i3BEH (not arrived yet) which is a newer product, to run a couple of VMs on VMWare ESXi. What I think I'll do is to switch initially planned roles. BEH will become my new multimedia PC and BNH will become the ESXi virtualization box.
