Add this to that list:
Optical drive for PC that can play UHD Blu-ray - NONE

I don't even know if one has even been announced. If I recall correctly, with Blu-ray, it was actually PC optical drive that came out first.

You are incorrect.

UHD BD is a higher capacity Blu-ray disc. https://en.wikipedia.org/wiki/Blu-ray#Ultra_HD_Blu-ray

Many optical drives can read these discs. However, hardly anyone has them in hand to do any current testing.

To "play" a UHD BD or even a regular BD on an optical drive you need to appropriate software and I'm sure PowerDVD is working to get their software to do that, if they haven't already.

I have tried it my LG BD-XL drive, it doesn't even recognize it. So, my information is first hand unlike you making speculations.

You have 1 first hand report. I've read many more who've achieved positive results. So unlike you I've done actual research rather than just jumped on my soap box to say I know everything because I did 1 test and my results are negative.

Never mind your original statement is still false because you failed to understand the difference between the drive reading a disc and the method then used for playback.

You really should have stopped when you were already behind rather than try to catch up and instead trip over your own feet and fall flat on your face. If you'd like to turn that scraped knee into a broken nose though, well, keep going as you were.
