I'm transferring this over from the UHD50 thread because it is specific to the UHD51a. 3DBob was kind enough to help me think through the possibility of using my HTPC to output Blu-ray 1080P frame-packed 3D to the UHD51a.

Edit: This card only has mini-display ports and DVI support, which is probably not going to work for you with no hdmi. You would have to deal with that as well.
I have not used this card personally, though. Considering the expense for such a card and the fact you can get a 4K bluray player for $90--http://www.bestbuy.com/site/lg-up875-4k-ultra-hd-3d-blu-ray-player-black/5979504.p?skuId=5979504 that does 4K HDR and Atmos, it seems like overkill to mess with a computer and also having to buy 3D player software and then getting it to work, which can be a mystical experience, trust me
. I can't vouch for the LG, but it gets good ratings and it sure is cheap.
The UHD51A offers the advantage of full frame-packed HD that a bluray player can produce. The UHD50 does not and requires a PC to drive it. That said, you can only pass SBS or Top/Bottom to the UHD50, so your PC player software would have to read the bluray and down-scale it to SBS or T/B. You would be better off going with the Benq HT2550, which supports full 3D HD and is the same price as the UHD50. That said, HT2550 users have found a problem with using 3D as it can't sync properly with DLPlink glasses. Benq has said they are going to fix that in firmware release soon, though. Lots to consider here. I personally am going to wait for the UHD51A.
After reading his comments I initially decided that I was going to bite the bullet and just get an external 3D Blu-ray player. But then I realized I was already going to get a new 4k HDR graphics card, I already have the latest PowerDVD, and I would need to get new 4k HDR cables either way, so it would actually be more expensive to go the external 3D Blu-ray player route.
Unfortunately, I discovered the card 3DBob referenced above does not support HDR. After a great deal of research, I found the PNY NVIDIA Quadro P1000 (VCQP1000-PB) http://www.newegg.com/Product/Produ...-645-_-Product
a quad-buffered 4k card with 4 simultaneously displayed mini DisplayPorts 1.4 (HDR) that costs about the same as the non-quad-buffered EVGA GeForce GTX 1050 Ti, which was the other 4K HDR card I was considering. Then I found the Club3D CAC-1180 Active mini Display Port 1.4 to HDMI 2.0a HDR Adapter (Support Displays up to 4k/UHD/ 4096x2160, 60Hz HDR) http://www.amazon.com/CAC-1180-Disp...DMI+4K+UHD+hdr
. This dongle meets all the necessary specs to enable the Quadro P1000 to deliver 4K HDR to the UHD51a.
I went several rounds with PNY Quadro tech support to ensure that the Quadro P1000 would indeed deliver Blu-ray frame-packed 3D to the UHD51a.
Yesterday, they confirmed it would (should) work.
Regarding your questions about our (VCQP1000-PB) NVIDIA Quadro P1000, it supports quad-buffered stereo, it supports Blu-ray, and, after reviewing the information linked below, I am confident that it supports frame-packed 3D.
Next step: Wait for few reviews/early adopter comments for the UHD50/UHD51a to determine if I want the UHD51a. If so, I'm going to give the Quadro P1000/Club3D Display Port 1.4 to HDMI 2.0a HDR Adapter a try.
Please feel free to let me know if you see any flaws in my plan!
