Samsung Odyssey G3 LS27AG300 monitor – Specs, Pros / Cons: Bringing Out The Creator Inside of The Gamer

The Samsung Odyssey G3 LS27AG300 is another one of their Gaming monitors, which easily can become a fantastic Creator machine. The G3 monitor comes with a Full HD VA panel that stretches across a 27-inch frame, reaching the bottom limit of pixel density when it comes to FHD screens. In terms of specs, it’s got the quintessential for any gaming monitor. The VA panel has a 144Hz refresh rate, a 1ms response time, as well as FreeSync Support.

Today we’re taking a walk around the Odyssey G3, including the design and the color reproduction. We’ll also check out its creator capabilities and how much we can improve them with our Display Profiles.

Drivers and Software

All drivers and manuals are available on Samsung’s Support Portal. Additionally, you can download the Easy Setting Box app, which gives you the option to create layouts and grids for multitasking.

Design and Connectivity

The design of the Samsung Odyssey G3 LS27AG300 comes with thin bezels on the sides and the top, while the chin is a lot thicker, bearing a Samsung logo as well as two protruding pieces on both ends, which make the monitor feel more rugged than it actually is. The backside has a textured pattern but is still entirely made from plastic. There’s the infamous Blue Translucent ring, which holds the stand attached to the back, while also acting as a pretty nice accent piece. The stand here is very good, having a wide base that supports the monitor in its entirety, as well as tons of adjustment, including Tilt, Pivot, Swivel, and Height.

In terms of ports, the Samsung Odyssey G3 LS27AG300 offers an HDMI 1.4 and a DisplayPort 1.2, as well as an audio jack, and a USB Service port.

Display quality, Buy our profiles, Verdict

The Samsung Odyssey G3 LS27AG300 brings a 27-inch Full HD screen (1920 x 1080p), which calculates to a pixel density of 81.59 PPI, a pitch of 0.3113 x 0.3113 mm, and a Retina distance of 42.14 inches or 107 cm. From this distance, the human eye can’t distinguish individual pixels.

The correlated color temperature on a white screen after a Factory Reset in sRGB mode is 6250 K (Luminance 150 cd/m2 at 20% Brightness). The average gamma value is 2.18.

Color coverage

Here’s an illustration (Fig. 1). The whole “sail-shaped” map below consists of all the colors we can see, while the black crooked line shows all the colors from real-world scenes and nature around us.

Then, we’ve drawn some of the most important and interesting color spaces, compared to the colors the panel of Samsung Odyssey G3 LS27AG300 can show:

Standard/For Web: sRGB – widely used color space for most consumer devices, ideal for Web design and development
For Print: AdobeRGB – used in professional photo editing, graphic design, and print
For Photographers/Video Editors: DCI-P3 – used in high-end film production, post-production, and digital cinema
Premium HDR: Rec.2020 – the widest consumer ITU color standard, covering a massive 75.8% of the visible spectrum, a benchmark for premium HDR content

Samsung Odyssey G3 LS27AG300: the yellow dashed triangle (– – – – – –) represents the range of colors this monitor can display. In our tests, we calculated the total color coverage of the monitor at 89% of the sRGB color gamut.


(Fig.1) Samsung Odyssey G3 LS27AG300 covers 89% of the Web colors (sRGB) 

This means that if the Samsung Odyssey G3 LS27AG300 tries to show any color outside of its triangle, it will show the closest color to it that’s inside the triangle.

Color accuracy

Now let’s see how big is the difference between the real colors and the one you’ll see on the Samsung Odyssey G3 LS27AG300. We measure that distance in DeltaE – the bigger the number, the more different they look.

For the next illustration, we’ve chosen 24 common colors like dark and light skin, blue sky, green grass, etc.

Values below 2.0 are considered suitable for color-sensitive work. Before our calibration of the Samsung Odyssey G3 LS27AG300, the Average color accuracy was 3.1 dE (Fig. 2), and with our Web Design and Office Work profile, it lowered to 1.3 dE (Fig. 3). This is a SIGNIFICANT 2.4X INCREASE. Also, dE values below 1.0 are indistinguishable by the human eye, so with a 1.3, you’re getting very accurate colors, ready for any type of color-related workload.

Health-Guard eliminates the harmful Pulse-Width Modulation (PWM) and reduces the negative Blue Light which affects our eyes and body. Since it’s custom-tailored for every panel, it manages to keep the colors perceptually accurate (they may seem strange at first but after a few minutes our brain will start recognizing them as accurate ones – that’s how Health-Guard differs from alternatives like f.lux).

Pro Tip: As the Health-Guard profile simulates paper and has as accurate as possible colors, it could be a great tool for prepress designers!

Gaming and Movies

We also have a third Gaming and Movies profile, which regulates the black colors, making dark areas in games and movies appear more visible, thus giving you a better viewing experience. Shooting at your opponent first can be a make-or-break moment, so make sure you’re best prepared with our profile.

In addition to receiving efficient and health-friendly profiles, by buying LaptopMedia's products you also support the development of our labs, where we test devices in order to produce the most objective reviews possible.

Office Work

Office Work should be used mostly by users who spend most of the time looking at pieces of text, tables or just surfing. This profile aims to deliver better distinctness and clarity by keeping a flat gamma curve (2.20), native color temperature and perceptually accurate colors.

Design and Gaming

This profile is aimed at designers who work with colors professionally, and for games and movies as well. Design and Gaming takes display panels to their limits, making them as accurate as possible in the sRGB IEC61966-2-1 standard for Web and HDTV, at white point D65.


Health-Guard eliminates the harmful Pulse-Width Modulation (PWM) and reduces the negative Blue Light which affects our eyes and body. Since it’s custom tailored for every panel, it manages to keep the colors perceptually accurate. Health-Guard simulates paper so the pressure on the eyes is greatly reduced.

The Samsung Odyssey G3 LS27AG300 is a great budget gaming monitor, thanks to its features. At 1080p, the 144Hz refresh rate and the FreeSync Premium support deliver smooth and tear-free gameplay. However, the Odyssey G3 offers features that make it more than a gaming monitor.

The design and construction are some of the best that we’ve seen, allowing you to ergonomically adjust the monitor in the best possible way. This is due to the stand, which adjusts in pretty much every way.

Now, getting to the crux of today’s tests, the Odyssey G3 gives us a pretty decent color coverage for a gaming monitor, at 89% of the sRGB color gamut. While not exactly, groundbreaking, this is great for gaming and good enough for a graphic designer, especially considering the color accuracy, which reaches very good levels.

Before our tune-up, the monitor has a dE value of 3.1. After applying our Web Design and Office Work profile, the dE value drops down to 1.3, which is a 2.4X increase. With it, the Samsung monitor can handle color-sensitive work.

Our other profiles improve the work of the monitor in other ways. For example, the Gaming and Movies profile keeps the black colors stable, which means that you can see more out of dark scenes and environments in both games and movies. As for the Health-Guard, it’s probably the most important one of the bunch, as health is always #1. It eliminates Blue Light emissions and PWM (Flickering), both of which have negative effects on your eyes and body.
