24 Inch Monitor Reviews – Best Buying Guide for 4K 24 inch Display, LCD and 24″ Panel For Sale
The basics of 24 inch 4K monitors
4K monitors of all types are now a serious and popular fixture of the PC display landscape and with good reason. For both gaming and professional needs, 4K resolution is becoming more of a “must-have” technology simply because it offers some clear benefits to its users over HD or lesser display formats, even in the smaller screen spaces of PC displays. Magnification of complex details in specific design work projects is much easier to manage with 4K and many professionals are recognizing this.
While the gaming angle for 4K monitors is still somewhat complicated by the fact that both the monitors themselves and graphics processing units haven’t quite caught up to the full mettle required of them to handle 4K at high frame rates and smoothly, these same obstacles don’t apply to work or office-related 4K display uses, where slower refresh rates and lower GPU processing needs can still deliver perfectly decent performance.
With that in mind, 24 inch 4K monitors of the kind we’re about to cover here are ideal pieces of technology for more office-oriented tasks. With a 24 inch display, one gets enough display space to feel comfortable and relatively unobstructed without having to handle the hefty space and power needs of a much larger 27 to 32 inch display. In simple terms, while 24 inch 4K monitors aren’t for everyone, their high pixel density combined with reasonable size makes them very attractive to a lot of users.
4K monitors are by no means all created equal and even among models of a specific size, a whole range of technical details can heavily influence how well their displays perform. Thus, some types of display lend themselves particularly well to certain things.
The most crucial display distinctions between different monitor technologies are their specific panel types and these can be divided mainly into twisted nematic (TN) panels, vertical alignment (VA) panels and IPS (In-plane switching) panels, which are the least common type on the market. Here is a basic breakdown of each type:
IPS: these panels are usually found in more expensive 4K monitors and with a bit of good reason. They usually offer some of the best quality on the market. IPS technology delivers a vibrant, bright display with strong colors, rich contrast and excellent viewing angles. For gamers, IPS is slightly less than ideal due to the slower response time it creates between onscreen elements and controllers or keyboards but as an all-around performance technology for 4K monitors used in non-gaming, IPS is superb. On a final note, IPS is the specific name of this technology mainly in LG PC monitors while other brands often use names like PLS (Plane to Line Switching) or AHVA (Advanced Hyper Viewing Angle). However, all of these basically describe the same IPS-style panel design.
TN: Twisted nematic panels are extremely common in the PC monitor world and are very commonly used with 4K and HD gaming PC displays. While TN technology usually results in weaker color reproduction, brightness and viewing angles than IPS display, it also delivers excellent response times between screen and keyboard or other similar control device. Furthermore, TN 4K monitors tend to be a fair bit more affordable than their IPS counterparts.
VA: Vertical alignment panels aren’t so commonly found in 4K monitors as IPS and TN panels but they have their benefits as well, with extremely rich contrast ratios, strong color display and great black levels. VA monitor panels also deliver great viewing angles, which are notably superior to those of TN. However, at least for gaming and some types of animation editing, they might be less than idea due to the ghosting effects they can produce. VA panel technology is also often somewhat more affordable than IPS in 4K screens.
Connectivity in 4K monitors of all types is generally pretty standardized across the board. Yes, some models come with an extra set of connection ports or a less common technology like Thunderbolt but for most PC monitors on the market, the connectivity fundamentals are going to consist of HDMI, USB, DisplayPort and audio connections. Some models will also include Mini DisplayPort along with regular DP connectivity.
That said, for any 4K monitor you’re thinking of buying, the connections you should absolutely have in your model of choice consist of at least one DisplayPort 1.2 connection, a couple of USB connections (preferably the newer, more powerful USB 3.0) and at least one HDMI 1.4 or if possible HDMI 2.0 connection. Some monitors today now come with HDMI 2.0 connectivity for HDR content and some of the most advanced new models on sale also include USB C and Thunderbolt 3 connectivity ports or even DisplayPort 1.3. However, these types of 4K Monitors remain rare and we have only one such model, LG’s 21 inch UltraFine 4K moniotr listed below which fits such advanced connectivity specs.
DisplayPort 1.2 is normally the most crucial monitor connectivity spec since it’s the port through which most 4K displays connect to a PC and its GPU for 4K ultra HD graphics at a smooth 60Hz refresh rate (60 frames per second of data). With HDMI 1.4, 4K monitors can also connect to other devices or PCs for 4K graphics at 30Hz (equal to about 30 frames per second) while some still rare PC monitors offer HDMI 2.0 as well, allowing them to transfer 4K visuals at 60Hz via HDMI. As for USB, a hub of at least a couple USB ports is very useful for connecting assorted peripheral devices like external hard drives, mobile phones, tablets and speakers or a mouse. Thus, USB ports are a crucial feature of your 24 inch monitor of choice, the more the better in fact.
4K monitor prices can vary ridiculously depending on specs and particular special features loaded into the machines. Thus, if you really want to go crazy on a hardcore professional visual design pro’s monitor that offers perfect advanced color coverage and high precision calibration capacity, you could easily spend more than $2000 on your monitor. Or in the other direction, if you just need a basic piece of display technology with decent color and the fine sharpness of 4K resolution, some models are available for less than $400, or the price of a high quality HD PC display.
Luckily, most smaller 24 inch 4K screens tend to cost less, with the truly professional displays usually also being much larger along with their high price, with displays of 28 inches or more (in some cases reaching up to 42 inches, the same size as a smaller UHD TV). The following 24 inch 4K monitors are generally priced at well below $500.
FreeSync and G-Sync
Finally, if gaming is your thing, then FreeSync and G-Sync are two technologies you really need to keep in mind. Both do the same thing, which is to synchronize the refresh rate and frame rate output between a 4K monitor and a PC’s graphics card. The result is a smoother, tear-free video quality that’s particularly useful for gameplay with 4K graphics. FreeSync is found in some 4K monitors and G-Sync in others, with the former technology being compatible with AMD GPUs and the latter with NVIDIA’s graphics cards.
The Best 24 inch 4K monitors on Sale today
Now without delaying any more, let’s get down to the business of the 24 inch 4K ultra HD monitors themselves. The following are some of the best models in this size range on the market today and all of them offer up a plethora of excellent display specs, design features and solid connectivity ports for whatever you need to do, be it gaming, design work or just browsing your favorite YouTube videos in some seriously awesome ultra HD clarity.
Samsung’s U24E590 is the smaller but equally awesome cousin of the 28 inch U28E590D 4K gaming monitor we’ve also previously reviewed and in its 24 inch typically stylish Samsung design, the U24E590 packs plenty of features and advanced specs.
For starters, this gamer-friendly display offers up AMD FreeSync technology for dynamic synching of your PC’s GPU with the display itself, for minimal input latency and dramatically reduced tearing. In addition to this, the U24E590 also comes with dual HDMI 2.0 ports for maximum 4K connectivity at 60Hz while also featuring DisplayPort 1.2 for more traditional GPU connection power, also at the monitor’s and your cards highest possible frame rates in ultra HD.
Then there is the display resolution on the U24E590’s TN screen. 3840 x 2160 pixels packed into a 24 inch display means some serious pixel density for maximum sharpness in native 4K content. Combine this with the monitor’s bright vibrant colors and very decent rich blacks, and you get yourself some excellent viewing characteristics. Finally, special display modification features like Picture-in-Picture and Picture-by-Picture are on hand for viewing video or graphics from two different UHD input sources at the same time.
This newest and most advanced 4K monitor on the market may not have a quite 24 inch display but it’s just too good of a piece of technology to not mention in this listing. The 4K UltraFine from LG is one stunning piece of display technology despite its compact built and comes with the sort of specs that will leave many professional and amateur users both with a serious urge to go out and grab a unit of their own. Working in conjunction with Apple for the relase of two new MacBook-friendly high performance monitors for late 2016, LG has released this 21.5 inch model along with its bigger, badder 27 inch 5K cousin to the consumer market. The 21.5 inch 4K UltraFine monitor offers up a stunning and uncommon true 4K resolution of 4096 x 2160 pixels, offers full DCI-P3 Wide color gamut coverage (a key component of HDR color like that found in 4K TVs) and one immaculately smooth pixel density across its 21.5 inch display.
Most importantly however, the advanced new connectivity specs of the UltraFine 4K from LG are what should send many MacBook owners running to pick up a copy for their larger editing projects. This little display comes with multiple USB-C Thunderbolt 3 ports for some dramatically turbocharged bandwidth that sits at a whopping 30 to 40Gbps for the upstream ports and 480 Mbps for the downstream ports. The USB-C Ports of the UltraFine 4K IPS monitor are powerful enough to deliver 4K graphics for multiple displays and they can work wonders with the display performance of this machine if it’s hooked to one of Apple’s newest MacBook notebooks.
The UltraSharp UP2414Q is definitely one of the less affordable 24 inch monitors with 4K resolution on the market, as you can see with the price tag above but it’s largely worth what it retails for. With excellent color accuracy that covers 100% of the sRGB spectrum and 99% of the even more advanced Adobe RGB color gamut, the UltraSharp UP2414Q really presents a vibrant, vividly realistic image quality for your consumption. Furthermore, because this is an IPS display, it also offers up great brightness, fine contrast ratios and superb viewing angles.
On top of these specs, the UltraSharp is also fully physically adjustable in true Dell style, with options for changing tilt, height, pivot and full VESA mounting. Dell has also added in some great function buttons for settings menu navigation, allowing for you to also choose from eight different preset modes that include variations for Movie, Game, Multimedia and others. Finally, connectivity on the UltraSharp UP2414Q is very decent, featuring four USB ports, one HDMI 1.4 port and a DisplayPort 1.2 connection.
Not only is the VX2475SMHL-4K highly affordable by 4Kmonitor standards, it’s also a wonderfully equipped and built monitor in most ways. With a beautifully sharp picture quality, excellent contrast and some rich, inky black colors, it also offers up a decent range of connectivity ports and a pleasing, somewhat minimalist aesthetic to its black body.
Once again, we have another IPS display on the VX2475SMHL-4K and this means vibrant colors, excellent viewing angles and super contrast. Furthermore, ViewSonic has introduced several preset picture modes, which include Standard, Game, Movie, Web, Text and Mono. There are also brightness and contrast adjustment options along with five different color temperature settings to boot.
On the other hand, while the VX2475SMHL-4K does offer decent MHL, HDMI and DisplayPort 1.2 connectivity through one MHL port, two HDMI 2.0 ports and one DP 1.2 slot, this 4K monitor strangely lacks USB connectivity of any kind, which is one serious oversight on the part of ViewSonic.
NEC MultiSync EA244UHD 4K UHD Monitor: $1,023.82
Finally, we come down to NEC’s MultiSync EA244UHD, what is at the same time the single most expensive mid-sized 24 inch 4K monitor on this list and also arguably one of the best we’ve seen so far as well. The EA244UHD definitely comes in at a high price, costing nearly twice as much as the next priciest model we’ve covered here but with those dollars spent, you get access to some truly exceptional specs for display, connectivity, adjustability and overall performance. While we’d argue that the EA244UHD could definitely use a price drop of a notch or two, it is definitely a real winner on the whole.
With some truly accurate color performance, superb grey-scale caliber and several different digital video inputs along with a high-speed USB 3.0 hub, the EA244UHD offers truly superb connectivity. Its ports specifically include two DisplayPort 1.2 ports, two HDMI ports (one of which doubles as an MHL connection) and a total of 4 USB 3.0 ports.
Finally, the EA244UHD is fully adjustable, with VESA mounting capacity as well. This is definitely a 24 inch 4K monitor to love, if only it were also on sale.
