Question about Philips 499P9H/00

Sorry - I may have expressed myself inaccurately. The information comes from Apple and works like this for me on Mac Min and Display.

TB3 corresponds to USB 3.1 in terms of connector design, but can transmit much higher bandwidths. The signal arrives at the monitor as Displayport. I briefly reconnected the cables. TB3 (USB 3.1) to Displayport (large connector) and TB3 (USB 3.1) to USB 3.1 on the monitor work for me. The quality of the USB/TB cable is important. The cheap ones (I only have one at hand) do not transmit the signal.

I connected my monitor to the Mac Mini with an OWC TB3 cable LMP THUNDERBOLT 3 (40GB/S) USB-C CABLE 2.0M and everything works. Unfortunately, Digitec does not yet carry this quality of TB3 cable and only has a 40GB, 0.5m cable on offer.

@digitec: Would not be bad if more TB3 quality cables > 0.5m were on offer :-)

I have the display on a Macbook Pro 2018 with USB-C - software version Big Sur. Initially, I tried it with a CHF60 Thunderbolt 3 cable from Belkin - it didn't work. However, with a USB C cable from Mio Star (Migros, USB 3.1 Gen.2) everything works perfectly, including the camera at full resolution (5120 x 1440).

A display with a resolution of 5120 x 2880 at 60 Hz via Thunderbolt 3 cable. Included cable is only USB-C not Thunderbolt
