Using a TV-sized display as a monitor always seemed like a fanciful idea. Until one day it wasn't. Thanks to the increasing commoditization of LCD panels and the continual downward pressure that has put on monitor prices, demand for large format monitors has been growing just as fast as monitors themselves. And while these kinds of large monitors are still far from ubiquitous, they've become an increasingly common sight in the monitor market.

Besides making them more accepted in general, one of the benefits of the normalization of large format monitors is that it's enticed more manufacturers to enter the field. And now, Iiyama, a respected display maker, has become the latest vendor to jump into the market, introducing their own 42.5-inch monitor for work and play.

Iiyama’s ProLite X4372UHSU-B1 is a 42.5-inch monitor featuring an IPS panel with a 3840x2160 resolution. The display features a typical brightness of 450 nits, a 1300:1 contrast ratio, a 4 ms response time, and a 60 Hz refresh rate. The monitor can reproduce 1.07 million of colors and is listed as supporting HDR, but the manufacturer doesn't list how much of the DCI-P3 gamut the monitor can reproduce, only noting that the LCD can cover 85% of the NTSC color gamut.

The manufacturer is positioning its ProLite X4372UHSU-B1 monitor for a wide range of applications, including CAD/CAM, entertainment, photography, and visualization. To that end, the monitor supports picture-by-picture and picture-in-picture capabilities, and comes with a total of four inputs: two DisplayPort 1.2 inputs, as well as two HDMI 2.0 ports. The monitor also has an outbound DisplayPort for daisy-chaining it with another LCD. In addition, the device has a quad-port USB hub supporting two 3.0 and two 2.0 connectors. On the audio side of matters, the LCD has two 9 W speakers, a line in as well as a headphone output.

Like many other large-sized monitors, the Iiyama ProLite X4372UHSU-B1 comes with a modest stand that can only adjust tilt. The good news, at least, is that it supports VESA mounts, so it can be used with a third party stands if necessary.

    No VGA?! What's wrong with these people? How am I supposed to make this work with my 486DX? Stupid design decisions from stupid design-deciding-deciders!

    How is this supposed to plug into my iSBX 275 Video Graphics Controller Multimodule Board?
  • Arsenica - Thursday, March 5, 2020 - link

    Don't even get me started with the lack of a MDA port.

    I'm fuming.

    Hey, I got a K6-2 sittin' next to me and I'd like to get some 43" Doom. Big F'ing Gun, indeed... oh, it is a 60 Hz display. Never mind, Doom runs at 70 Hz.

    In all seriousness, though... CAN we go back to VGA? HDMI is just awful in a multitude of ways, and I'm not really sure how much DisplayPort actually is.

    HDMI has no place outside of an AV stack, and should just not be present of desktop monitors at all. DisplayPort or nothing (even dual-link DVI has insufficient bandwidth to handle modern displays).

    While I agree that DisplayPort _should_ be the default PC video interface, the fact is that most people are find HDMI familiar and comfortable. It looks like DP is on its way out as a result of HDMI steadily gaining in popularity.

    4k and not even DP 1.4? Lame.
  • sandtitz - Thursday, March 5, 2020 - link

    This is a 4k@60 monitor, DP 1.2 is enough.
  • Valantar - Thursday, March 5, 2020 - link

    Yeah, why splurge for a fancy controller supporting 1.4 when it's not going to be utilized anyhow? Sounds rather wasteful.
  • extide - Thursday, March 5, 2020 - link

    It has a MST HUB and DP OUT port. With DP 1.4 you could chain a second 4K60 display from this screen, and have enough B/W. With DP 1.2, the output port is essentially useless.
