The 21:9 37.5"
HP Z38c IPS Curved Display with a resolution of 3,840 x 1,600 and a radius of curvature of 2,300mm is probably the most interesting. It has a DisplayPort 1.2, HDM 2.0 and USB-C. Via USB-C, 65 watts are available for the operation of a laptop, for example. At a brightness of 300nits, the Z38c achieves a contrast of 1,000:1.
The HP Z38c Curved Display costs approximately 1,200 and is now available. The other six displays (HP Z27n, Z24nf, Z24n, Z24i, Z23n and Z22n G2) are between 21.5 and 27" in size and cost between 200 and 500 dollars. All of them are factory calibrated in color, almost borderless and therefore suitable for multi-monitor setups.
