Earlier this week I posted on the sony x800m2 owners thread a query on why I didn’t see a big difference in UHD from my brand new 800m2 versus HD blueray from my oppo 105. I posted the same query on the Sony 900e owners thread.
I learned that the titles I was comparing weren’t very good exemplars (https://www.blu-ray.com/4k/
). I also learned, from responses and from reviewing this same site, that there are not that many titles that show an appreciable difference in PQ from HD blueray to UHD blueray. This surprised me.
I decided to try Planet Earth 2 and the first Disney reboot of Star Wars as they appeared to be better UHD examples. I watched Planet Earth 2 with the 800m2 on the 900e. The 800m2 goes directly to input 2 on the 900e, and, yes, that is a certified hdmi 2.0 cable and the TV confirms both 4k input and HDR. It is a jaw dropping video, the PQ is just amazing. Highly recommend.
I also bought the regular HD blueray. This was played on an Oppo 105 with hdmi directly to TV input 4 with the same settings. (Obviously when hdr is detected on input 2 that changes brightness, etc. so they are not exact in playback). Again the PQ was just stunning. But when scenes were compared back and forth to the 800m2 there were noticeable differences; the sand under the lions paw was crisper, more textile, and the colors in the city scenes were more vibrant on the 800m2. These differences were noticeable, and better, but not huge.
On the Star Wars videos, I saw even less of a difference (there was some) but I thought the scenes that were primarily CG looked more CGish with the UHD HDR version than in HD. I could easily watch both, though.
Based on this unscientific limited 4 disc comparison, I plan to return this very nice UHD player because, basically, the PQ on the 900e is so good on plain HD sources. No knock on the 800m2, I like its build and how it performed, but I’ll revisit this when the UHD source material is more consistent and mature.
YMMV. Thanks for your responses, I learned a lot.
