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.
I happened to buy the same, and import it from Germany to the UK.
Was very excited for it as it featured a very similar DPI to a 27" 1440p Korean import, coming from 3+ 1080p monitors originally the lack of bezels was incredible.
It's not built for gaming at all though, extreme screen tearing and poor response times has me now looking to replace the 27" 1440p Korean import with something >144Hz and G-Sync, before replacing the Philips BDM40.
Yeah, I got that Philips too. For games 40 inch at 4K resolution is really a lot more practical then 38 inch with an odd resolution, and it's cheaper too.
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.
