I have a NUC7i5BNH with Intel Iris Graphics 640. Very happy with it except for video playback: Mediacenters like JRiver and Kodi have 'automatic display mode changing' as an option in order to have the best video playback. Display mode changing works, I can check in Intel Iris Graphic Control Panel and see that the refresh rate of the display has changed. Issue: the display 'Scaling' also changes. From 'Maintain Display Scaling' to 'Scale Full Screen'. The result is that my LG Oled (b6) looses Trumotion and Real Cinema options.
I asked JRiver about Display Scaling.
Display Scaling should not change. Display mode changing is about refresh rates.
It seems the scaling issue is graphics-specific.
I wonder if the change to 'Scale Full Screen' can be prevented or changed to 'Maintain Display Scaling'?
Hello Wanner, sad news... You guys could not replicate the issue probably because you don't have a LG Oled B6 connected to your Intel Nuc 🙂
I have installed Windows 10 three times over the past 20 month and everytime the display mode issue was there. It is not a simple driver issue.
I was about to give up but today I found a way to make my NUC function the way it should!
Basically it means that I found a LG Oled-setting (Picture Mode settings -> Aspect Ratio: 'All direction Zoom' + 'Just Scan') in combination with a Intel Graphics Control Panel setting (desktop resolution: 1920x1080, 50p, SCALING: 'Maintain Aspect Ratio') that makes everything work the way it should. It involved connecting the NUC with HDMI to a Denon AVR and the USB-C-output (through a adapter to hdmi) directly to LG Oled and going through many configuration steps.
Result: I can play any video with Kodi or JRiver with settings to automatic change the display frame rate AND preserve the Trumotion-option on LG Oled...
It should not be this hard. My 10 year old Shuttle with AMD Radeon 4550 was so easy to set up. Just connect to AVR or directly to LG Oled and everything worked fine, with Trumotion active on LG Oled.
Finally I am happy with my Intel Nuc!
I like to thank everyone involved in solving my 'display-issue'. This posting was the last step for me before giving up on Intel NUC. Thanks to your response Wanner, and the efforts made to replicate the display-issue, I kept researching and testing. My testing finally paid off.
Right now I have disconnected the Thunderbolt-hdmi cable and the primary HDMI still functions correctly (connected to Denon AVR), giving me the necessary display modes to use trumotion on LG Oled! The Picture Mode Settings on LG Oled are normal ( 16:9 and 'Just Scan'), the Intel Graphics CP settings are normal (3840x2160, 50p, scaling defaults to 'Maintain display scaling' after video playback so I leave it like that).
I cannot explain what happened. At this moment Windows shows different display-information (e.g. 'resolution of active signal' 3840x2160; this used to be: 4096x2160) and the 'recommended resolution' now is 3840x2160 (used to be 4096x2160). Colorspace has also changed from RGB to YCbCr420. In Intel Graphics CP there is no option anymore for YCbCr. Quantization range is set to 'Full' (as always).
I am okay with this. LG Oled can be used with all its options available, both in 1920x1080 and 3840x2160 resolution!
