You have to select Expert mode
I selected only 4k resolutions these turned blue everything else is White
Tried playing the same test file as before I still get the message "upscaling not required" when trying to activate upscaling
Ok, it sounds like you've set the whitelist correctly. This was definitely what fixed for me and ontap as per above. This may be a silly question, but are you sure your Shield is set to a 4k output in the Shield display settings and not 1080p?
Yes I double checked this The Shield is set to 4k output
Playing a 1080p file TV Info button says it's receiving 1080p signal so I'm assuming the TV is upscaling.
I'm not going to debate if LG is better than Shield at AI Upscaling
I suspect unless you can run the same set up side by side a mortal like myself would not be able tell the difference
I couldn't tell the difference between playing the same 1080p file in Kodi and in plex with AI Upscaling on
I could see a difference in plex with switching AI Upscaling on and off and in demo mode
I forgot to check the TV info whilst doing this
The TV also recognises a 4K HDR and Dolby Vision
As Whitelisting fixed this for you are you saying you can activate AI Upscaling on the Shield when playing a 1080p file in kodi?
Hi Gidyfish,
I have re-tested my system to ensure what I’ve written down below is correct:
My TV = LG 4k OLED
My receiver = 4k Denon
2019 Nvidia Shield connected directly to receiver.
Shield set to 4k/50 in the display settings (I’m based in the UK hence 25/50 frame for UK based streaming apps)
Kodi set to match framerate on start/stop in the Player section.
Test file = 1080p (1920x1080), 23.976fps
Scenario 1: In Whitelist, all resolutions de-selected apart from 3840x2160, 23.98fps (Kodi rounds up to 2 decimal places)
Result – using the video info setting on my receiver, it reports a 4k, 24fps input. Shield AI upscaling works and switches between AI and Basic using the top right button with the 3 horizontal bars on the remote (I think I set this up in the Shield settings somewhere)
Scenario 2: In Whitelist, all resolutions de-selected apart from 1920x1080, 23.98fps.
Result – using the video info setting on my receiver, it reports a 1080p, 24fps input. Shield AI upscaling does not work.
Scenario 3: In Whitelist, all resolutions de-selected. Whitelist section now greyed out.
Result – using the video info setting on my receiver, it reports a 4k, 24fps input. Shield AI upscaling does work as per scenario 1.
Conclusion:
In my case, the initial problem getting the AI upscaling to work for Kodi was because I originally set it up to whitelist every single resolution and framerate available which had the effect of Kodi/Shield outputting video as per the source file and therefore the TV was doing the upscaling on anything below native 4K rather than the Shield. Consequence = no AI.
My initial recommendation of just whitelisting just the 4k resolutions, whilst fixing the issue for me, doesn’t actually seem 100% necessary as not using any whitelist at all still enables a 4k output and AI upscaling active.
In your scenario, it seems that whatever you set in the Kodi system / display it still outputs a 1080p signal as per your source file which would explain why the AI upscaling is not working.
As per your original post, you say AI works on Plex. If your TV is correctly reporting the input signal it receives then this logically should be shown as 4k when using Plex – please check.
