This will play all 1080 FHD in native resolution and refresh rate allowing the TV to handle upscaling. It will also play 4k UHD at native resolution and proper refresh rate. Vizio and Sony TV's will handle the proper colorspace for 709 (otherwise you may want to manually change the shield to the colorspace 709/2020 ) most common for the material you watch. Setting the base resolution and colorspace let the app do or do not with the rest works for Kodi/SPMC/MRMC.
I concur with this. I did a lot of testing to compare Kodi on the shield tv to madVR on PC and Dune HD Solo 4K player and during these tests I tried to understand what in the shield is called "blurry" by lots of people.
I found out that it seems like it's when it needs to scale, either upscale or downscale, but it's way worst when Kodi on the shield UPscale than when it DOWNscale.
By the way, Kodi v18 Leia that I use permits you to have the Kodi GUI in 4K 60hz (or 59.94Hz like I prefer to use it) AND it will switch to 1080p on 1080p source because they added a whitelist where you select a list of [email protected]
detected by Kodi that your TV support. It also plays 25 fps files @25Hz and not 50Hz and 29.97 fps files @29.97Hz and not at @59.94Hz which I find pretty nice even if the difference is probably nothing in quality since one is just doubling the time each frames appear probably. Also, that last part might already be there on Kodi v17, I didn't notice.
On my OLED I just select all the 1080p and all the 4k options in the whitelist of Kodi and the TV will do the scaling for 1080p sources.
I know the LG OLEDs are not known for their upscaling quality but to my eyes the quality is close to madVR even and WAY better than what Kodi itself does. In fact the upscaling of Kodi on the shield is by far the worst of all the tests I did (madVR, Dune HD Solo 4K and Kodi on Shield).
So yeah, if your tv is half decent at upscaling let it do the job or use something else in the chain for upscaling.
I have two questions though:
1) Does the colorspace issue happens on an LG OLED C7? I set it to limited, auto colorspace and auto hdr. I didn't do tests to try and see color differences in details yet but was wondering if it's the case? If so what's the best setting to put the shield at if I don't want to switch it everytime on that TV?
2) Is the bad PQ on upscaling with Kodi on the shield due to the Shield or Kodi? My guess would be Kodi?
I'll probably try to upscale with Kodi on the PC to try and respond to question #2
