Introducing a $1500+ professional grade 40" 5k2K (138 dpi) monitor in mid 2023 without hdmi 2.1 and/or displayport 2.0 is simply bad business. Thunderbolt4 is a fine, IF you use macs and/or the handful of Intel based motherboards that actually support it.
The problem of course is that on the Windows PC side of things 16-core AMD Ryzens has significantly outsold Intel's often bewildering array of mostly mediocre but always power hungry and hot CPU's...In other words, this particularly configuration of monitor has been out almost 2 years in one form or another leaves more than half the market looking at the lack of HDMI 2.1 ports and the dependence on Thunderbolt 4 ports thinking; screw me? no screw you...
And by no means am I singling out Philips here. For years before Philips popped up with its to little too late offering, the likes Dell, LG, Leveno, HP, etc. have all deliberately thumbed their noses at a lot of professional users who use AMD processors or simply prefer to avoid the expense of Thunderbolt and stick with easy of use and simplicity of hdmi 2.1
This sounds near-identical to existing 5k2k monitors such as the LG, which I have. It's a nice display, no problem driving it via DisplayPort or USB-C, but it doesn't get very bright so you'll need a light controlled space.
Philips has unveiled the 40B1U6903CH, a 40-inch curved monitor with a 5K2K resolution and a 75 Hz refresh rate. The ultra-wide monitor also has Thunderbolt 4 ports, a separate USB hub and a Windows Hello webcam.
