Just bought my first Philips monitor, a 43" giganticus 4k DisplayHDR 1000-certified, a Philips Momentum, and I am terrifically impressed. I had thought my previous monitor, a BenQ EW-3270U was really nice--but it pales beside this Philips. The Philips is also a Wide Color Gamut SDR monitor, and it's more than obvious in use. The BenQ was supposed to be, as well, but you couldn't tell it was WCG using it. Typical brightness on this monitor is ~600-~700 nits, 1030 nits in HDR 1000 mode (via Display Port 1.4)--whereas the max brightness of the BenQ at max was ~308 nits. Typical on the BenQ was ~250 nits. Amazingly, at $850, this monitor only cost ~$50-$100 more than the BenQ when it was originally released (The EW-3270U costs about $400 now.) Very happy with this Philips--and very surprised by it, too...
Pleasantly so.
