What would (or could) be the difference in 3D "quality" between displaying two interlaced pictures in a 2160 resolution and the "Hardware Based" option in a 1080 resolution? Can someone explain?

3D mvc is two full resolution 1080p frames that when rendered on passive OLED 4K are essentially interlaced where the passive glasses are polarized such that each eye sees essentially the odd or even scan lines and your brain interprets the 3D

1080p passive TVs render each 1080p frame in half resolution since you need both presented at the same time to see the 3D

1080p active TVs show both fullframe images in sequence at a high refresh rate where your glasses shutter in sync with the tv to show you both at approx the same time and your brain sees 3D. active shutter requires carefully calibrated sets and extreme ambient light control to reduce eye strain and artifacts.


for SBS or OU 3D i believe you have two half resolution images displayed at the same time for passive and in sequence for active where your glasses present both at same time to your eyes and you see 3D


as far as i know anything other than MVC encoded 3D is half resolution. now it is possible that standard Kodi will take an MVC encoded movie and decode a single 2D frame and then output SBS or OU and give you the 3D effect. this is "fake" 3D in the sense that the movie was not encoded this way. it's like taking any 2D source and having your tv "upscale" to 3D.

i could also be way off here. google is your friend. but the reason we want MVC decoding is because that is full resolution for each eye. for active shutter TVs at 1080p and passive 3D TVs that are 4K

passive 1080p TVs are half res regardless of source encoding
Thank you for replying, above knowledge is something I was aware of.

With the 4K 3D passive generation, specific the Oled's, there is a whole new player to the ballgame. And what was before maybe isn't really up to date info anymore regarding this.

I compared in my situation 3D with this specific Kodi build in W10 using BR ISO's on;
(with auto refresh-rate active)

- an 1080P active 3D Plasma (with the "hardware" setting > 1080p/60Hz) Haswell hardware
- an 1080P passive 3D LCD (with the "hardware" setting > 1080p/60Hz) Haswell hardware
- an 2160P passive 3D Oled (with "hardware" setting thru HDMI 1.4 > 1080p/60Hz) Haswell hardware
- an 2160P passive 3D Oled (with "interlaced" setting thru DP 1.2 > HDMI 2.0a > 2160p/30Hz ) Haswell hardware (no picture when "hardware" selected, and screen stays black)
- an 2160P passive 3D Oled (with "interlaced" setting thru DP 1.2 > HDMI 2.0a > 2160p/60Hz ) Kaby Lake hardware (no picture when "hardware" selected, and screen stays black)

The last 3 give the best 3D picture and experience overall, but the last one is top notch (as far as that goes for 3D at home), maybe this is Kaby Lake related?

So maybe, in some cases, there should not be a focus on the "hardware" part in the 3D settings, that is what I mean?
Kodi 18.2 RC [MVC build] Shuttle DH270 [Kaby Lake i3-7300/HD630 graphics] Windows 10 - 1903 [3840x2160/60Hz]
4k video trough HDMI 2.0a port direct to LG Oled 55EF950V (with 2018 panel) HDR [success] HD audio through HDMI 1.4 port direct to NR1606 receiver
Kodi [4k/60Hz success] [i3D 4k success] HDR done by Kodi [no support]
