For professional use, Philips has provided the 4K UHD monitor 27B1U7903, which features mini-LED technology and a Thunderbolt 4 interface. The luminosity is particularly high at up to 1,400 cd/m².
Mini LEDs on 2,304 dimming zones
Mini-LED technology supplies far more light-emitting diodes than classic LED backlights for liquid crystal screens (LCD) and thus ensures more brightness and a correspondingly higher contrast ratio, which, however, cannot keep up with OLEDs. In the case of the 27-inch Philips 27B1U7903, the mini-LEDs are divided into 2,304 dimming zones whose brightness can be regulated separately.

The LCD panel illuminated by it is of the IPS type with high viewing angle stability. Philips states 10-bit color depth and around 99 percent coverage of the Adobe RGB and Rec 709 color spaces, and the larger Rec 2020 color space is covered at a good 80 percent. From the factory, the display is set to a color distance of Delta E < 1 calibrated, which should appeal to professionals who demand accurate color reproduction. The DisplayHDR 1400 certification certifies the said peak brightness of 1,400 cd/m² in HDR mode. The 3,840 × 2,160 pixels are displayed with a refresh rate of 60 Hz.
Thunderbolt 4 as input and output
In addition to the mini-LED backlight, Thunderbolt 4 is another special feature that is still rarely found. The fast universal interface, which offers all the features of USB4 1.0 and more, uses the USB-C connector, which is becoming more and more common. Data, video signals and electricity are transmitted via it. The monitor has an upstream port (up to 90 watts) and a downstream port (up to 15 watts). There are also four USB-A sockets, one DisplayPort 1.4, two HDMI 2.0 as well as an audio output and a network connection (1 Gbit/s). With these connections, the monitor becomes a docking station for notebooks with USB-C.

The upscale equipment has its price: Philips quotes around 1,300 euros as a recommended retail price for immediate availability. This is not that expensive for mini LED monitors with professional standards.
