4K HDR 60hz 4:4:4 is not that common even today.
How so? There are many TVs that can do the specs you're rating. Unless we're talking full 10-bit HDR and not 8bit HDR.

Exactly it's not possible under HDMI 2.0 because HDR uses 10 bit,some TV's even do their processing at 12 bit. HDR can't go over 4:2:2 and DP 1.2 does not support HDR

I've never heard of a 4K monitor that cannot do 4K RGB Full at 60 Hz (which is basically 4:4:4).

HDR works fine on DP 1.2.

Yes HDR is supposed to be 10 bit from the go.

HDTV can use 4:2:2 8bit 4K60 HDR over HDMI2.0

This monitor can do 4:4:4 10bit 4K60 HDR if i am not wrong since it is HDR1000 certified?

There's enough bandwidth for full HDR 4:4:4 at 4K60? If so, that's great news. Makes you wonder why TVs today didn't have it if this monitor can pull those specs with HDMI 2.0, unless this is all over DP.

It's a bit sad that they made such a feature-rich display with improved VA response times while skimping on backlight uniformity.

Nope.

HDMI 2.0 cand do: 4K 4:4:4 SDR 8-bit, 4K 4:2:2 HDR 10-bit, 4K 4:2:0 HDR 12-bit. Chroma subsampling only matters for text in Windows. If you play a game or watch a movie there is no needs for 4:4:4.

It's on Amazon for preorder and I bought one to compare to my NU8000 which is basically the TV equivalent. I can only get the NU8000 down to 42hz Freesync range so hopefully better luck with the Phillips.

I would buy a x27 but just can't use anything under 40 anymore after using 40+ TV's monitors for so long and feel it's a waste of time in such a small format.

HDR works fine at 4K 8-bit RGB 60 Hz. You need 10-bit encodes for HDR but the GPU dithering from 10-bit to 8-bit for display is fine.

I think the GPU having to dither down to 8bit for HDMI2.0 output is bad, HDR content definitely needs 10bit to avoid banding.
While a monitor using FRC to dither to 10bit is less bad.

That is said, anyone confirm this monitor, DP1.2a, can do HDR 10bit, 4K60 4:4:4?

Banding is not an issue with dithering, you get a raised noise floor but not banding.

Review is up with measurements:

Uniformity is horrific but on the flip side it's one of if not the fastest VA in terms of pixel response. Really wish it was FALD but either way it's a nice stop gap until the 4K 144hz FALD stuff not only becomes available in this size but is introduced at a reasonable price over the next couple years.

EDIT: You can clearly see vertical bands/DSE on their windows display settings sample image. If this is another panel lottery in that regard I'm only going to play once.

I wonder if the text fringing and vertical bands from 2 reviews are because this monitor DP1.2a cannot do full 4:4:4 chroma over 4K60 HDR?
No mention as yet, meh!
