for me, the only limitation in having it perform at its best has been the quality of the source material sent to it. 50% of all free to air tv channels here are still only SD, and the ones using HD are at a low bit rate ( 4 mb/sec to 8 mb/sec in TS format)
in comparison an old style SD dvd is usually around 10 - 15 mb/sec, and blu-ray HD closer to 25 - 35 mb/sec (and 4k bluray should be 50-70 mb/sec). an additional issue is that (like with the old redbook music cd's), the fact a video is sold on a dvd or blu-ray disc doesnt mean the source file was mastered correctly (or was even sourced from a high quality video file), so DVD/Bluray video content quality (and SD or HD tv broadcasts) can vary a great deal.
we still dont have ANY 4k free to air tv channels here, and foxtel cable tv (the only cable service here) doesnt provide it either (and if they did, it would be mostly upscaled 2k anyway for the next few years, like they did when first providing 1080). so that leaves netflix and other online streaming services, and the 4k video they provide is also still a LOW mb/sec bitrate (currently) , which isnt even as good in video quality as most movies on a 2K bluray disc (which has a 3x higher bitrate for ex). The higher luma detail in the 4k streaming services however does provide a benefit visually, so its not all bad. the main reason people are more and more switching to these streaming services is to get access to different content, NOT because the video is 4k in its full 50 mb/sec glory that it can/should be
several of the 4k bluray player manufacturers have already discontinued making players for the format (oppo, samsung etc), and with new 4k bluray movie disc's sold at 50$ a pop, the amount of discs we are going to buy would always be a small niche product for most people. the future of video (tv/movies etc) is definitely 4k and even a progression to 8k, there is just very little of it available right now
to the end consumer (where i live). i hear parts of europe are starting to use 4k for special event broadcasts (like football world cup, Olympics etc), so hopefully it will become more available soon. but meanwhile in real life, imho there is still no real reason to hurry and put down 3000 $ + to get a high quality 4k tv if you already have a very good 2K model
(unless you want a bigger size screen etc). also many people with new 4k tv's here decide not to watch the SD channels anymore because upscaling from SD to 4k doesnt really work well enough.
for those currently looking to buy a good tv (mid-range or high end), there is in the last 2 years or so a great choice of good 4k models from several manufacturers (samsung QD models, Oleds from sony and LG etc), and there would be no reason to buy a 2k tv (unless you go for the lowest cost, but none of the better brands make premium 2K tv models anymore).
in my experience, tv display technology progress has significantly outpaced the provision of good quality video source material.
so for me, i am still extremely happy with the careful choice i made to select this w900a for 1080 and SD video viewing, and am in no hurry to try and replace it with a 4k unit. for the 4k video sources i do watch, i can get 80% of the benefit by using the right 2K down-scaling process,
