This one is certified for VESA DisplayHDR 600, which requires a minimum of 600 cd/m2 in both small patches for highlights (at least 10% of the screen) as well as full-screen for brief periods to convey the sharp brightness during scenes of explosions. The panel also must produce 350 cd/m2 across the whole panel for long periods of time. It is VESA’s second-highest DisplayHDR certification behind DisplayHDR 1000 (excluding the True Black variants, which add low-brightness performance to the criteria).
In terms of its other features: it is built around a VA panel that has a 4K (3840 x 2160) native resolution. The monitor can accept inputs over 2x HDMI, DisplayPort, or USB-C. Its color gamut is listed as 95% DCI-P3. It is only capable of a 60Hz refresh rate, which may or may not be something that people care about. Personally, I value higher refresh rates, although that’s mostly for typical 2D things, like moving my mouse and simple UI animations. Above 60 FPS is less noticeable for me in busy scenes, like most first-person shooters, although it does add a bit to the experience.
The LG 32UL750-W is currently on pre-order for an MSRP of $749.99. B&H Photo has it listed for $746.99. As far as I know, neither LG nor B&H Photo lists when these pre-orders will ship. Anandtech says that the monitor is already shipping in Japan, however.
