Haven't yet tried, but there are 4K screens which also do 3D, although you'll probably be hard pressed to find 4K 3D material as studios don't seem too keen on these - you'd be re-using your Blu-Ray 1080p 3D content upscaled in that case.
The thing with upscaling Blu-Ray is that depending on the source material and up-scaling algorithms things can look a little 'patchy' in places, at least to me sitting up close it looks that way on a 4K TV which isn't HDR equipped. It could be another story with HDR, assuming the upscaling process use HDR (hey and possibly WCG) to make a better up-scaled image.
Yes I know that Yash: 4K is only 2D, and 3D is only 2K. * Can you really upscale 3D/2K to 4K? I did not read about it; perhaps I missed it somewhere.
And I'm not buying and 4K OLED or LED TVs that don't have 3D capability; I'm just too much 3D love invested financially.
So no cheap TVs for me. No curve either. I want flat 3D geometry. I'll take my time...no rush, no Oppo 3D/4K BR player yet.
And those 4K Blu-rays I'll give them time to come down to Earth's reality for the common mortals...till greed fade away. :b
1. You want Rio summer olympic games in UHD, and in 3D...so you need that special 4K TV...be it LED or OLED.
2. You want Atmos and DTS:X immersive audio...so you need that new pre/pro 11.2-channel (or receiver). ...With HDMI 2.0c and HDCP 2.2
3. You need that UHD/4K/3D Blu-ray player. And right now Samsung and Panasonic are not the ones for me.
4. You need hi-speed HDMI 2.0 cables for 4K and 3D.
Brief you need to replace everything you have with the new stuff, and all that new stuff cost much more than yesterday's older stuff like when you could buy a 65" class 3D plasma TV for only $999. Sure you can buy a 65" 4K TV for $999, but no 3D capability, and no top quality picture.
And that new 4K pre/pro...it goes from roughly $3,000 to $30,000 (Trinnov 4K Altitude64). Or JBL Synthesis 4K.
HDMI 4K cables? Transparent, Shunyata, AudioQuest, Belkin, MonoPrice, Monster Cable, ...lots of choices, lots of prices.
4K Blu-ray players? Way too early still in that game. HDR and Dolby Vision and all that jazz.
* Plasma TVs near the end were the good times; not like @ the beginning when a 50" plasma was $20,000
The Kuros were also the good times.
We're still waiting for 4K front projectors that can do the real thing and accessible for most common mortals. We'll miss it for the Rio summer olympic games, starting Friday.
