Samsung U24E590D Review: Budget 24-inch 4K IPS FreeSync Monitor

Samsung U24E590D

Samsung has finally started shipping out the anticipated 24-inch Samsung U24E590D monitor. The Samsung U28E590D started shipping some time ago and now it had a pretty good reception. Both monitors are very budget friendly, but still of high quality. The two monitors are very similar to each other with some key differences that makes the U24E590D both superior and inferior. The U24E590D has a PLS panel, which is an IPS-type of panel that Samsung produces, offering superior viewing angles and color quality, while the U28E590D has a TN panel, offering great response times.
The other key difference is of course the size. A 24-inch monitor creates a better pixel density and offers a more immersive gaming experience because of the smaller screen, but offers less screen space.

Despite these differences, they also feature some common traits. Both displays feature two HDMI ports: one HDMI 2.0 (MHL) port and one HDMI 1.4 port. Furthermore, the screen offers a DisplayPort 1.2 connector. This connector is important, because both the Samsung U24E590D and the Samsung U28E590D are AMD FreeSync certified, meaning that the monitor’s refresh rate operates in an interval. For these monitors, the AMD FreeSync range is only 45-60Hz, so it is not much and you will not feel a big difference in gaming, unless you hit the sweet spot between 45-60FPS, which can be hard on a 4K resolution.

Another thing these monitors share is the low price tag. If you want a 24-inch monitor with 4K graphics for gaming, graphics editing in UHD or watching videos in Ultra HD, then this monitor is certainly a strong starting point. For not less than $400, you can get this monitor and the 28-inch older variant is not more expensive. This is what makes this display the best 4K budget monitor, and the 28-inch version is also awarded this title for those seeking a larger screen size.

First impressions

The Samsung U24E590D may be a small monitor, but it still has a lot to offer, whether you are a gamer, graphics designer or just about anything else. First of all, both this monitor and the U28E590D both support AMD FreeSync technology, meaning that they can dynamically change the refresh refresh rate of the monitor, also known as Adaptive Sync. This is a major feature to have and is very appealing to gamers. The FreeSync range of both the monitors is 45Hz-60Hz, which is a little window to be honest and we would at least have hoped for 40Hz-60Hz.

The other positive thing to say about this affordable 4K monitor is the rich connectivity options. It has a HDMI 2.0 port which is a new thing that manufacturers have started to implement in 4K monitors. With HDMI 2.0, you are able to stream 4K video from sources like Netflix, HBO, Hulu, Amazon Prime Instant Video and more! So in other words, you are able to transmit 4K video at 60Hz with a HDMI 2.0 connector and you no longer necessarily have to use a DisplayPort 1.2 connector.

Finally, one of the most beautiful things about this monitor is the PLS panel, which is just Samsung’s version of IPS (In-Plane Switching). That allows for much greater viewing angles and superior color quality than the U28E590D which has a TN panel.

The monitor has its downsides too. These downsides are very minor and the monitor in general is of high quality actually. First of all, the PLS panel, while having its own set of upsides, also has its downsides. It offers a slower response time due to the nature of how these panels work, but in general they are becoming faster and faster every year. The U24E590D has a response time of 4ms, which isn’t particularly bad at all. For competitive gamers that play FPS games and are looking for the lowest input lag possible while still having a 4K display, the U28E590D is most certainly a better choice for them.
Second of all, if you are used to a larger monitor, then you will immediately notice the limited display size and you will probably want a little bigger monitor.

All in all, the Samsung U24E590D is a great and cheap 4K monitor that is very cheap while also of a high quality. It is certainly a great deal considering the generous price tag.

Display quality

Samsung are known for making high quality monitors with great display quality despite their product’s low price tag. This is also the case with the 24 4K display, the U24E590D and the 4K 28in monitor, the U28E590D. This is because Samsung knows how to make the most out of even budget minded specifications. Samsung’s 4K monitors deliver a surprisingly good display quality even though it has specifications that are far from professional 4K monitors and TVs.

First of all, the U24E590D has a matte screen just like the U28E590D. Matte screens significantly reduce glare, but they do not look as aesthetic as glossy screens. The reason that Samsung has provided this 4K monitor with a matte screen is probably due to the fact that the monitor has a low brightness, but it is nothing too serious.

As far as color quality goes, the display provided some very satisfying results. Even though the screen is only equipped with 8-bit color that only supports up to 16.7 million colors, it managed to cover over 98% of sRGB color gamut. Most professional higher-grade monitors are equipped with 10-bit color that allows for up to 1.07 billion colors, and the U28E590D is equipped with such a panel.

Some last things we wanted to mention are the the game mode settings which you can use to get the best visual quality in your games. Furthermore, the display has flicker-free technology, Eye Saver mode, picture-by-picture (PnP), picture-in-picture (PiP) and MagicBright, which is a feature from Samsung that improves the brightness of the monitor. We tested this feature in our Samsung U24E590D review and it was great!

This monitor has as we mentioned previously great options for connectivity. First of all, it offers a HDMI 2.0 port which is an alternative to the DisplayPort and can allow you to transmit 4K resolution video data at 60Hz smoothly. You can use the HDMI 2.0, HDMI 1.4 and DisplayPort 1.2 to connect multiple input sources, so you get the most out of your gaming and other computer usage. To take advantage of the AMD FreeSync technology, you will have to use the DisplayPort 1.2 port, since the Adaptive Sync protocol is built in the DisplayPort connector, but is only optional so not all monitors with DisplayPort 1.2a are FreeSync compatible.

The downsides are that the monitor does not have any USB ports at all and no DVI ports or DVI-D ports either. This is also the case with the U28E590D and they could at least have two USB ports, like a majority of other monitors built these days.

cheapest 4k ips monitor


The Samsung U24E590D is a very affordable 4K monitor with superb display quality, and is one the cheapest 4K monitor you can get right now. Samsung has done a very good job producing this display and considering the suggested retail price is only $399, you should get this monitor if you are looking a new 4K monitor that is affordable and has a screen size of 24-inches. If you are looking for an affordable 28-inch 4K monitor, then we suggest you take a look at the larger version of this monitor, the 28-inch Samsung U28E590D. The differences between the two monitors have already been addressed in the review. Given that the monitor is IPS-panel based, it is also the cheapest 4K IPS monitor in 2015.

    Freesync range 45-60 make it pretty useless 🙁
    Any idea if the U28E850R will be different ?

  • TristanSDX

    Two questions to reviewers:
    – does FreeSync mode still exhibits blur ? Lot of FreeSync monitors do not use overdrive, while operationg in FreeSync mode. Some models recently are fixed from this disadvantage, but not all.

    – is 8bit color native, or simulated using 6bit + FRC ? Cheaper panels still are using 6bit + FRC

    Thx in advance

  • FreeSync itself does not exhibit motion blur, so it is something the display manufacturer has to include and it can’t work alongside FreeSync because it requires strobing the backlight at a constant refresh rate. The 8-bit color in this monitor is true 8-bit.

  • Yes, the FreeSync range is disappointing for many. Samsung does not like to reveal the FreeSync range of their monitors. I have tried asking them, but they don’t know and they referred me to something else that was irrelevant. My guess (to not disappoint anyone) is that the U28E850R will also have a 45-60Hz range.

    So from what I can tell from owning this monitor, it seems like the upper range for frame rate is actually 64hz, reported in Windows, steam framerate overlay and fraps. Is there a method to try at home to find out if this is actually correct? Is it also possible to test lower limits? Since Samsung does not release official ranges for Freesync it would be helpful to know.

    I was wondering if this monitor will work in Ultra HD with Netflix on PC. Netflix requires a 60 hz monitor that has a HDCP 2.2 compatible connection. Does this monitor meet those requirements?
