Same here. I bought a Philips BDM4065UC monitor in 2015 (40 inch, 3840x2160 resolution) for 740 € (in Germany) and I'm loving it. The only cave-at with that model is that reaction time is a bit slow (I would guess 5 ms between full black and full white).
When I replace it, the replacement will be the same size and resolution, but I'll probably go for OLED and HDR-10 or better.
