Dr_b_is it possible to use the entire viewable screen area for one input device, or is this 2 monitors stacked, where inputs for one show up on the bottom half, and inputs for the other device show up on the top, or is it both?

Chrispy_2560x1440 on a 21.5" is nasty. Why would you want two of those in a weirdo arrangement that doesn't really benefit from a zero-bezel solution anyway?

ZetZetWhy is it nasty? I would think this is mostly used for text and graphs, those tend to scale well so resolution doesn't really matter. I see it as just a slightly wider vertical monitor. Almost a square. I don't think LG decided to just put this out into the world, they probably had requests from some company and just decided to release it out into the wild too.

Chrispy_Nasty because of non-integer scaling to get a usable DPI. You're going to be using 150% scaling, most likely which is the worst thing ever for content creators who deal primarily with raster graphics.

The press release and use-case for this monitor isn't a contiguous image like ultrawide is useful for gaming or 2.35:1 movie content, it's for devs and movie editors who don't care about the bezel and are probably more interested in being able to angle the top monitor down so that it doesn't catch the glare off the ceiling lights and also so that the viewing angle is better.

ZetZetInteresting that they market it like that. I thought they would be aiming mostly at the people who use vertical monitors. But I still believe that this panel is specially made for some weird use case and they're just re-using it here.

TheLostSwedeIt's single input if you read the spec.
This might help.

Chrispy_People who use vertical monitors usually want the 16:9 aspect in portrait, because they're dealing with portrait documents or phone content that is somewhere between 9:16 and 1:2 usually.

Having an unusual aspect ratio is fine; It's not for me, and it's not for video editors or content creators in the real world (my admin desk in the main office is sandwiched between the graphics department and the visualisation department) but nobody's forcing me to buy it and more choice on the market can only be a good thing.

I suspect LG don't really know who it's best aimed at which is why they picked some ill-fitting examples for their marketing but there will be people somewhere who are willing to pay for a niche product like this. I would guess that these are salvaged slices from large-format displays that had too many dead pixels or defects at one side, perhaps. I'm not really 100% sure if that's how LCD panel manufacture works, or whether it's only possible to determine the defects after it's been cut from motherglass and wired up to a display controller - Maybe someone more knowledgeable can confirm or correct me.

thewanMr lost being lost again. IF you read the spec, it has 4 inputs. 2 HDMI, 1 DP and 1 USB C. Also those same specs also say it supports PBP, which if you don't know your monitor/tv terms, stands for picture by picture. This means it supports displaying two separate sources side by side.

For this monitor, as I was curious about it too so I read the manual, here is a shot of the part of the manual that describes the PBP function. The left and right descriptor is confusing but the picture below it clearly shows top and bottom though.:

R0H1TThat's really only an issue on Windows, on Linux or even Mac no problems with that.

Chrispy_1.5 pixels per pixel is bad when you work with raster content, period. It doesn't matter what OS you're using...

I agree that the OS UI itself also looks like garbage at 150% in Windows, but that's a different complaint altogether. Half of the graphics team edit video on a Mac and you simply do not want interpolation blur in the content you are working on, ever.

lemonadesodaI author and edit a lot of A4 portrait documents. This looks great. Would love to have better resolution though... reading an on-screen PDF is still far away from the quality/resolution of even the cheapest laser printer. We need moar rez

Another positive note: matte. Not glossy
