A Review of the Samsung U24E590 4K IPS Monitor

by on July 12, 2015

After a long stretch of anticipation, Samsung fairly recently finally started shipping out its UE590D 4K monitors. We’ve already reviewed the larger of these two, the U28E590D and now it’s the little brother’s turn.

The U24E590D is in most ways similar to its larger, more expensive cousin but a number of key differences make this specific model both superior and inferior to the 28 inch version.

For starters, it features a much smaller 24 inch screen that creates a better pixel density, is easier to position in a smaller space and also, obviously, offers less viewing space for gamers who prefer a more immersive experience. On top of this, the U24E590D delivers a slower response time of several ms grey-to-grey thanks to its PLS panel, as opposed to the TN display of the U28E590D. Furthermore, color gamut coverage and brightness are reduced in the 24 inch UE590D.

However, despite these reductions in specs, this little brother version of the larger, pricier Samsung U28E590D does feature the same HDMI 2.0, Display Port 1.2 and HDMI 1.4 connectivity of the 28 inch model and both offer the same contrast ratio, at least according to Samsung.

Of course, there is also price. The U24E590D may be a bit small, but neither is it ridiculously miniscule. And if you’re willing to settle for a 24 inch screen during 4K gaming and graphics editing in UHD, then you can save quite a few dollars with this model and its price tag of less than $400.

The Good

The U24E590D may be a relatively small 4K ultra HD PC monitor but it still packs a whack of good features that work for both gamers and visual design users.

For starters, there’s the monitor’s HDMI 2.0 connectivity. This is a new feature in 4K PCs and it’s a relief to finally see it arrive. For one thing, HDMI 2.0 paves the way for actually being able to access studio and OTT 4K entertainment on your PC from sources such as Netflix and Amazon Prime Instant video, just as soon as OS like Windows can get their stuff settled with proper content copy protection. Secondly, and more immediately, HDMI 2.0 means access to a second channel for transmitting 4K video, games or anything else at a much smoother 60Hz between PC monitor and graphics card. Previously, this was only available through DisplayPort 1.2 connections or via Thunderbolt 2 if a particular monitor/GPU happened to have it. Now, here comes HDMI 2.0. The HDMI in the U24E590D, let’s you get your 4K ultra HD content at 60Hz even through connections to AV devices.

Next, the U24E590D, like its larger cousin the U28E590D, offers AMD FreeSync technology. This is one major bonus and should be of particular interest to gamers who want 4K resolution at smooth refresh rates without breaking the $500 barrier in their monitor.

What FreeSync does is let you synchronize the refresh rate of the U24E590D (or whatever monitor the technology is installed in) with the frame rate of the content as it’s being fed in from your PC GPU. FreeSync is designed to work exceptionally well on PCs with AMD graphics cards, naturally.

The Bad

The U24E590D is of course also far from perfect and it comes with its share of little flaws. However, nothing about this monitor really stands out as particularly awful, there are simply some details which are less than ideal.

To begin with, this is a PLS display technology monitor without the same excellent response time of its larger cousin the U28E590D. Thus, while the FreeSync is present, along with most other similar features, the PLS screen creates a slightly “slow” 4 ms response time. Most gamers probably won’t even notice the difference but the detail is worth mentioning at least.

Secondly, don’t expect the real brightness of the U24E590D to match its advertised rating. The larger and arguably superior U28E590D often tested with a real brightness in the 300 cd/m2 range despite being advertised as having a brightness of 370 cd/m2. Thus, for the U24E590D and its labeled rating of 300 cd/m2, we can expect less than ideal levels of 280 cd/m2 or lower even.

Finally, while the small 24 inch screen of the U24E590D may be great for certain limited space situations, it really doesn’t have the same impact as a 28 inch screen or larger, particularly when it comes to displaying 4K graphics.

Final Thoughts

The Samsung U24E590D is overall a fantastic deal and especially given its low price. While it comes with a few minor deficiencies, this 24 inch monitor is loaded with excellent features for both gamers and even semi-professional users. The HDMI 2.0 connectivity and FreeSync really work to seal the deal at such a low price tag.

The U24E590D is a pretty simple and straightforward monitor as far as 4K hardware for PC goes. However, this simplicity doesn’t mean a lack of quality or specific and particularly strong features. Thus, to summarize once again:

The first highlight whose flexibility users can definitely enjoy is the simple fact that dual HDMI 2.0 ports are included in the U24E590D. This means triple connectivity to external devices and potentially even AV players for watching 4K content right on ones PC at a smooth 60Hz from multiple sources. We said triple connectivity for external devices. This because there is also the DisplayPort 1.2 socket, which itself also connects to virtually all GPUs on the market and can also deliver 4K video at 60Hz. The HDMI 2.0 connectivity is now also becoming more common in GPUs, just as it starts to appear in monitors like the U24E590D.

Next among the highlights of this model is the already mentioned FreeSync. This is a major bonus feature in such an affordable model and even many more expensive, overtly gaming-oriented 4K monitors lack thus extremely useful technology. With FreeSync, the U24E590D can synchronize its onscreen refresh rate with the frame rates of any given 4K game or piece of content, as well as with the PC GPU itself, thus leading to a much smoother flow of game or video content that’s free of artifacts or splitting and stutter. While the U24E590D isn’t the most gaming-friendly monitor on the market today, the inclusion of FreeSync makes it a surprisingly ideal choice for users who want display quality while saving on their 4K PC gaming rig.

Finally, the U24E590D is simply elegant to behold. Unlike many 4K displays, which oddly look like they were designed by hardware engineers from a decade ago, the U24E590D is aesthetic wherever you place it and Samsung is known for excelling at this visually pleasing look in its technology.

Visual Specs

Samsung is one of the name brand display manufacturers on the market that’s generally known for the quality of its visual specs, even when they’re more on the economical side. This quality definitely applies to the manufacturers 4K TVs, which are considered some of the best on sale today even when we’re talking about the cheaper models. The same applies to the Samsung 4K monitors of the company. This is something notable to virtually all models of Samsung display monitors.

Thus, the U24E590D manages to deliver a generally great picture quality despite being far from a UHD display with professional-grade specs, and this is partly due to the simple fact that Samsung knows how to make the most of even more economical display designs.

For starters, the U24E590D comes with a matte screen (like its bigger brother the U28E590D) and while some users might be fans of gloss because of how much “prettier” it looks, the matte of the U24E590D does a lot to reduce glare. This is particularly useful because the brightness of the U24E590D is pretty low to begin with. This latter aspect is one of the screen’s minor deficiencies but nothing too serious. In this case, Samsung gave the U24E590D screen a maximal brightness of just 300 cd/m2 and the display will often only give out 40 or more cd/m2 less than that so anything that minimizes glare is a benefit.

As for color reproduction, we also see quality of construction trump nominal specs. The U24E590D is equipped only with 8-bit color and thus supports just 16.7 million colors, unlike the 10-bits and 1.07 billion colors of most pro monitors. Despite this, the screen pulls out a solid 99% of the sRGB color gamut. This is done without frame control technology and the color reproduction on the screen definitely looks good even if it’s not spectacular. The larger brother of the U24E590D, the U28E590D does deliver 10-bit 1.07 billion color range.

Finally, there is also a game mode setting built right into the U24E590D for one button calibration of visual settings ideal for PC gaming. On top of this, the U24E590D also offers flicker reduction technology, Eye Saver mode, picture-by-picture and picture-in-picture as well as Samsung’s MagicBright technology that makes the most of the slightly limited 300 cd brightness.


The connectivity options of the U24E590D are both excellent and oddly deficient in a couple of ways. On the one hand, you get the superb benefit of three options for connecting the monitor to GPUs and external AV devices at 60Hz via the dual HDMI 2.0 ports and the one DisplayPort 1.2 slot. This can offer some great opportunities for gaming, 4K content viewing and screen splitting for the content of two different PCs.

On the other hand, the U24E590D doesn’t offer DVI, Dual Link DVI or, worst of all, USB ports. The lack of USB is particularly annoying and this is also a feature shared with its brother the U28E590D.

The U24E590D’s awesome FreeSync technology is built into the monitors DisplayPort 1.2 connection only, but this shouldn’t be a problem since DP 1.2 is the only way to connect with AMD GPUs anyhow.


The Samsung U24E590D is one of the more affordable 4K monitors on sale right now and Samsung has really put together a solid package for the $399 USD that this screen is retailing for as of its fairly recent release.

Not so Great

To summarize the not so great aspects of the U24E590D quickly: The lack of USB ports, somewhat low brightness, slightly slow grey-to-grey response time and rather small 24 inch screen are all relatively minor flaws in this otherwise very good 4K ultra HD PC display.


• Excellent price
• FreeSync technology
• Great color despite 8-bit limitation
• Dual HDMI 2.0
• Generally great visual features


• PLS screen produces slow g-to-g response time
• No USB ports
• Small display space

    Unfortunately U24E590 has no HDCP 2.2
    I hoped i could use my Nvidia Shield TV and watch Netflix 4K on this Monitor.

    In short No HDCP 2.2 = No Netflix 4K / No 4K Movies (4K BluRay).
    Well… hope does not equal knowledge.

      I’m not sure what the Nvidia Shield’s problem is; it supports 4K UHD Blu-ray through a connected Xbox One S for me; and supports all manner of 4K through a Google ChromeCast Ultra and an AppleTV 4K.

      I unlocked the hdcp 2.2 on this monitor by using a 4K splitter: the type that has its own power source.
      I now get 4K Netflix via PS4,Xbox ,shield tv or Apple TV on this monitor

    Lol! How can a “rather small 24 inch screen” be a negative point of a 24 inch screen? Not everyone wants >28″

    The Samsung (24″) UE590 UHD-QHD Monitor U24E590D DOES support 1 Billion colors!

    I got so confused with this rather incestuous review. Are the 24inch and 28inch brothers or cousins? It was all over the place.

      Hey there Conrad. the only major difference between these two monitors is their display panel type. The 28 inch model comes with a TN panel and the 24 inch model with an IPS panel. this means that the IPS monitor might have slightly weaker black levels and more importantly, its response time will be slightly higher than that of the 28 inch version. Both however come with AMD FreeSync frame-rate syncing technology, so they’re pretty good for gaming either way.

    This review was more like blah blah was exactly as reading specs and making sentences out of them. Wanna make a meaningful review? start with screen measurement and show us i.e. SDR color gamut. Otherwise I can also read specs!
    unfortunately it is the case for many reviews.
