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.

    I just wish to find a monitor that will force a default full rgb range (0-255) instead of limited (16-235) over HDMI via its EDID. It is a by product of TV usage that always defaults the hdmi ports to limited range, which is terrible and makes no sense for monitors. Yet I have not found one monitor yet that presents EDID defaults for its HDMI ports to full range. I assume because manufacturers assume the consumer might connect a TV source. Reply

    Huh? At least on NVIDIA, the driver takes care of that, however, even without the driver my monitors default to full. My current ones have HDR, but my old 1440p ones did as well. Reply

    Not over HDMI. How do you know if it defaults to full range if you can't change the settings? Every monitor presents I've found defaults to limited over HDMI. THEN you have to set your driver settings. However, on some drivers, in certain cases, like upgrading on intel, it resets back I've found Reply

    You will not find one, because HDMI IS FOR AV. Get it the hell out of your desktop display chain and you will remove a whole load of self-induced headaches. Reply

    As a TV this look great. It's getting difficult these days to find one that comes without malware. Reply

    No HDMI 2.1, no Displayport 1.4+, outdated I/O (no USB4 or Thunderbolt 3?), & abysmal HDR for a 2020 product. Reply

    And how many monitors support what you just mentioned? And just to make clear, there is no such thing as a USB 4 capable monitor or high HDR for IPS. Reply

    And not curved. Why you would want 40"+ of real estate and not have it wrap around the user....is beyond me. Reply
