Hmm, appears there are many catches with this expensive monitor that I'm now coming to terms with. I bought them from shopBLT, since they had them at the discounted price before Dell discounted the price, and it's beyond the return dates now.
To summarize and share:
1) It's DisplayHDR 400 certified! But... the HDR on this monitor is next to worthless. It doesn't provide the promised improved contrast or color accuracy. Instead, it makes everything brighter and washes out colors in HDR photos and videos.
2) It's got enhanced USB-C connectivity! But... Regardless of how you set it up, you get the maximum of 10Gbps to share across 7 ports. If you run it through a hub that doesn't support DisplayPort 1.4, or a MacBook Pro pre-2020, you'll need to prioritize resolution and the USB-hub will be 1/10 the speed. This ones not necessarily Dell's fault, there are lots of USB Hubs out there. But Mac users would be better off docking with thunderbolt, using only 1-2 USB port on the monitor for a webcam.
3) It's got magnets for a custom fitting Dell sound bar and its Microsoft Teams and Zoom certified! But... the sound bar costs $80, takes up a USB port, and sounds worse than a cell phone speaker.
Anyways, I've been so focused on this monitor that I didn't notice that Dell announced the Dell
P2723QE. Looks like basically the same monitor, a couple less USB ports, no HDR, 350 nits of brightness instead of 400, and 1:1000 contrast ratio. Not bad to save $150 from the Ultrasharp version.
Does anyone know if the U2723QE's "400 cd/m" brightness claim is valid for non HDR mode?
