Why you can trust Tom's Hardware Our expert reviewers spend hours testing and comparing products and services so you can choose the best for you. Find out more about how we test.

The DualUp is like no other monitor I’ve ever reviewed, so comparisons to like displays aren’t feasible. It’s close in pixel density to a 32-inch Ultra HD monitor, but no one would be choosing between those two kinds of displays. At this point in time, it is unique. With that said, I ran the same battery of tests on it as I would any monitor.

Pixel Response and Input Lag

Click here to read up on our pixel response and input lag testing procedures.

Gaming is certainly not this monitor’s forte, but one could play less frenetic titles on it and have a good time. I ran my response and lag tests and got results typical of a 60 Hz enterprise monitor.

  • Response Time – 28ms
  • Absolute Input Lag – 68ms

You won’t be winning any frag contests on one of these but for casual gaming, it’s perfectly usable. The overdrive is best set to its lowest setting. Higher options cause visible ghosting. Having been spoiled by faster displays, I found motion blur at 60 fps to be somewhat distracting. Your perception may be different.

Viewing Angles

The DualUp is a quality IPS panel with excellent viewing angles. At 45 degrees to the sides, the picture takes on a slight green tint with only around a 10% reduction in brightness. Detail remains clear with no apparent change to gamma. The top view washes out a bit with a 40% brightness drop. You’d have to be tall indeed to look down on one of these screens.

Screen Uniformity

  • Screen Uniformity – Deviation From Center: 5.95%

My DualUp 28MQ780 sample did extremely well in the uniformity test with just 5.95% deviation from the center zone. No visible glow or bleed was observed. Color patterns also showed no visible anomalies.

    This would be a pretty sweet coding monitor!

    Consider this vs 2 bog standard (200-250$) UHD monitors with vesa arms
    1 . Games -- how many titles support a single monitor of this resolution vs dual monitor support. Of course both configurations would require some really high end GFX.
    consuming video-- why would you require to see a play list this long.
    Web browsing -- most websites would do better with a UHD in portrait mode, same for coding.
    Photo and video editing -- you can have a professional monitor for the subject (photo or video) and a standard monitor for toolbars/thumbnails etc.
    Request could you also give gamut volume and coverage vs AdobeRGB. Should not take very long and I think it still has relevance in print work. Also, every DSLR and mirrorless supports AdobeRGB

    I think its mainly for productivity and programming while being borderless. Two individual monitors next to each other is never going to be as nice as one large panel with no bezels.

    ...or get a dell professional that rotates 90 degrees...

    If you really like the shape, ok. Otherwise, save big $s and get a 4k. You'll also get more pixels.

    If you do buy this, get some protection against problems. LG "warranty" service will leave you with an empty desk for up to a month.

    When the first desktop LCD panels appeared, they too were made in 4:3 aspect like a television.

    It's not entirely untrue since there were indeed 4 : 3 models from the beginning but I suppose you meant 5 : 4, which was the dominant aspect ratio. For example, EIZO in one of their first lineups of LCDs offered two models: L66 (1280 \00d7 1024, 5 : 4) and L360 (1024 \00d7 768, 4 : 3).

    Not the way I code. I often have about 4-5 files open at a time, usually positioned next to each other. Also, a couple terminal windows on a second monitor (or off in the corner of a single 4k monitor I sometimes use).

    I do want a bit more vertical realestate, but this is too much. I wish 16:10 monitors were more popular. I had a 1920x1200 monitor and it was great. I'd love a 2560x1600.

    Depends on whether you use them for the same thing. I tend to put terminal windows and API docs on the second monitor, which is slightly off to the side. My primary is bigger and directly in front of me.

    When I switch to a different setup with just a single 32" 4k monitor, I find I miss having the borders of the second monitor for facilitating window placement & layout. First world problems, I know.

    My question is - how well does it work with Raspberry Pi 4 ? Are two HDMI outputs needed, or does it run with only one (it should)? Are there any problems like EDID information incompatibility, does it run out of the box etc.

    I think this would be a good monitor for coding - fitting most of the functions on one page, hence making better feeling for what's inside what (nested loops etc).

    Raspberry Pi 4 is my personal workstation now, 'cause it's powerful enough for my needs and dead silent. And most of the time I'm doing research on the internet and writing code, browsing long logs, using ssh.

    I've been waiting for this type of aspect ratio since widescreen BS came in. The reason not to get a widescreen monitor and rotate it is subpixel antialiasing though, which greatly helps with horizontal resolution (or vertical, if you rotate widescreen monitor, but I don't consider it usable for nice rendered alphabets).

    Mind you, the vertical number of pixels is even higher than on my 16:10 4k monitor (2880 vs 2400).

    It sounds possible that this monitor size will become popular but consider that as a poineer device the LG is priced over the cost of many large 4K monitors and most usable 40in-60in 4K TVs. I just bought two LG 32in 32UL500-W 4K monitors during the Eggs sale at ran head-to-head with Prime Days. They were $250 each and though also only 60hz they did have adaptive sync. I'm running an Acer 48in 4K monitor which I used for coding plus I have a Samsung 28in 4K as a secondary monitor and I have an old Seiki 39in 4K which defaults to a TV but is also connected to my PC to function as a third monitor when needed. That's 3840x2160 per monitor and in the L shape that I have them set up in that gives me a tallest vertical of 4320 pixels and longest horizontal of 7680 pixels. I have used both long dimensions before especially when working on large spreadsheets.

    Even though I'm retired now I've kept the same arrangement as I am used to it.
