with the IPS panel the best is the 27UK650, even better than the 27UL650?
They're basically the same monitor, as is the UL550, but the 550 had a perceived black depth increasing
matte grey bezel versus the
650 and 850's perceived black depth decreasing inner black or fake frame-less casing's bezel.
The tested monitors are all ranked in the
Best Monitor sections of my
Best Reviewed Flicker Free 27" 4-5K AHVA/IPS/PLS buying guide.
As I understand Philips does not have FreeSync 276E8VJSB
Correct, and the PS4 Pro does not support Free-Sync. If you really want Free-Sync the ViewSonic XG2700-4K supports it, is very accurate and has a perceived black depth increasing grey bezel. It uses an older panel (my VP2780-3K uses the same panel which I compared to the UL550) with a bit more glow than the UL550, but you probably will not notice unless your room lighting is very dim.
If the panel is VA then the best would be the EW3270U
Best for non-HDR content. If some over-saturation is not a bother the Philips is better since it has back-light dimming and superior HDR color.
What about the LG 32uk550? nothing is said and is very well priced for the features that it has, right?
Untested.
I would like the monitor to be HDR.
Nearly full HDR support from monitors costs >1500. In this price range the HDR support offered by monitors is <30% and I would choose the Philips 276E8VJSB over every 4K monitor under 1000$ aside from the BenQ PD3200U and ViewSonic XG2700-4K.
