What small small 4k monitors are available that are less than 24 inches? The smaller and more affordable the better.

  • Less than (i.e. not including) 24 inch nominal size (a 23.8 inch diagonal is a "24 inch" display)
  • Minimum 4k (3840x2160) resolution
  • No constraint on aspect ratio
  • Available to consumers now or some time in the past (could buy used)
  • Include a price if available
  • Manufacturer links please

I know of these:

    Interestingly there's a few laptops (ranging down to 12 inches) with panels that would fit your needs, but I can't think of any consumer displays under 24 inches. My own research seems to suggest that at regular viewing distances, 4k is optimal at 27" size... http://superuser.com/questions/990799/will-the-pixel-density-difference-be-visible-between-4k-and-2k-monitors-at-27-s/991823#991823 if you're curious. https://www.adafruit.com/products/1652 is the closest thing I can think of that's modern but not quite there. What do you want to use this for? – Journeyman Geek Jan 25 '16 at 11:56
  • As a general-purpose desktop display (naturally with a shorter viewing distance) and potentially attached to a VESA wall mount. – ebpa Jan 25 '16 at 17:32
  • Exactly my question, I was trying to find a side-monitor for the 27" iMac where 24" is too big, likely 21-22 should be the sweet spot for using it in portrait mode and BORDERLESS (no bezel) – sorin Feb 12 '19 at 09:16

I found that LG has recently released a 22" (21.5" Diagonal) UltraFine™ 4K IPS LED Monitor that has a resolution of 4096 x 2304.

SmallHD has a 22" 4K OLED monitor, MON-OLED-22, widely available, for the small price of 12 000 US dollars.

The Panasonic Toughpad 4K Tablet is 20" and the specs mention HDMI 2.0 input on the "standard" model, the FZ-Y1. I still see it at some places around 2200 USD, eBay has a few for similar, it's an old one.

The LG 24UD58-B is a 23.8" 2160p (4k) monitor. It has a maximum 60 Hz refresh rate and FreeSync adaptive framerate support for between 40-60 Hz. It is also relatively expensive and can be bought for less than $300 new. It is a good size to run at 2x scaling for an "effective" 1080p resolution for sharp text.

I wouldn't recommend going for a 24 in 4k as it isn't recommended for the eye.

Check out the Dell P2415Q if you don't change your mind and go for a 24 in monitor. It is priced at around 425 dollars for which you can get good TV.

    Can you add more reasons why you recommend this monitor? Also, ebpa is looking for 23" and smaller monitors. This is too big. – Cfinley Jan 27 '16 at 16:43
  • I own and regularly use Dell's P2415Q and UP2414Q monitors. Personally I prefer the UP2414Q model because they cause me fewer problems after their power is interrupted at the power strip and they have tactile non-capacitive buttons. They are both good monitors (which I would recommend), but as @Cfinley pointed out I'm asking about smaller monitors. – ebpa Jan 28 '16 at 03:15

    Why do you say higher pixel density isn't good for the eye? Modern operating systems do display scaling, so things are legible regardless of your pixel density. – ebpa Jan 28 '16 at 03:22
  • The cost goes up as they try to squeeze in more pixels within a smaller body. When you have a lot of pixels it strains your eye if you are not used to it – Dhruva Jan 29 '16 at 07:33
  • try the dell xps 13/15 4k variants – Dhruva Jan 29 '16 at 07:37
  • Real life is like a 24" 8k monitor, actually an infinity-k monitor, so that must really strain your eye ;) (Unless, of course, you have special glasses that pixelate your world.) – Jared Thirsk Jan 17 '18 at 19:31
  • I use daily a 13" 4k display on my Lenovo Yoga 3 Pro laptop and appreciate the pixels. (Granted, I have it flipped backward so it is closer to me.) I don't understand why they don't make smaller 15"-17" 4K monitors, as I want to have an array of them and not have them take up too much space. Also, now we have cell phones that are higher than FHD. – Jared Thirsk Jan 17 '18 at 19:35
  • These kinds of answers are simply not helpful. You do not know what the OPs requirements are. For me, I'm looking for a 21" 4k that I can run at Retina (2x) scaling, making everything appear the effective size of a 1080p display. – James Aug 21 '22 at 14:50
