I don't plan to upgrade my current 1080p projector anytime soon, but wouldn't mind picking up one of these instead of a regular BR player to replace my current 6 year old BR player. Second, my current setup uses a 40' run of HDMI cable to the PJ - would that be a problem with this player for 1080p content?

I have a 50" LG plasma and a LG PF1500 1080p projector on a 106" screen. I've got a 3 foot cable from the UP870 to my receiver and a 50 foot Redmere HDMI from the receiver to the projector. Zero issue with handshake or anything in this setup. If you want I could switch the redmere to the player to test directly if you'd like, but I have zero doubts it will work fine (and I assume if you have a pj, you must have speakers and therefore a receiver anyway). I am not fully confident in the redmere cable for UHD though, it may not work, or maybe it will, don't know, but it works fine right now for 1080p (at 1080p RGB its not using any more bandwidth than my pc or previous bluray player, which was set to rgb 12bit/deepcolor)
I've been VERY happy with this player when connected to my 1080p pj. I did some comparisons of regular Bluray and UHD bluray on the pj. The UHD colors are noticeably better, more vivid and pop-y. There is also a subtle but noticeable sharpening compared to regular bluray that is very satisfying (to my eye, none of my friends would likely notice, but I am super picky about a/v quality, they can all watch movies on any screen, I absolutely cannot watch on any old tv and tv speakers). I am using RGB setting on the player, but I haven't done extensive testing to see the difference between RGB and YCBCR. My receiver reports it is receiving 36bit RGB from the player, so the player is automatically outputting at 12bit, presumably downscaling 2160p 10bit to 1080p 10bit and padding to 12bit (at least I hope thats what its doing, and that its not downscaling to 8bit and padding to 12bit). This is interesting since all my previous bluray players you had to set it to deep color to output 12bit but this LG does it automatically with no changeable setting available at all; it must detect the highest value possible for the display and send that, otherwise some displays that don't accept 12bit would show a black screen if it only ever sent 12bit, right? I know from extensive testing in the past with my htpc that the pj does a good job of accepting and displaying 4:4:4 RGB, but I don't think there is a way to test for sure if the LG player is properly downscaling 4:2:0 2160 to 4:4:4 1080, but if its not then I guess its better that I don't know or it would bug me, lol.
Overall I feel very satisfied with this slight but noticeable (to me) upgrade in PQ until UHD projectors are more affordable in a couple years. Whether its downscaling "properly" (4:4:4 10bit 1080p instead of 4:2:0 8bit 1080p) I don't know, but its good enough for now and it will all sort itself out when UHD projectors come down in price.
Funny sidenote: I hooked this up to a friends 4k tv just to test and when I tested the player outputting 1080p to a 2160p tv while playing a UHD bluray it looked just laughably bad. The process of downscaling UHD bluray to 1080p and then having the tv upscale it back to 2160p had some hilariously bad artifacting, just unwatchable for even a blind person. Rule #1
