The Samsung Odyssey G5 S27AG50 is an entry-level 1440p gaming monitor. Part of Samsung's 2021 Odyssey gaming lineup, it's newer than the Samsung Odyssey G5 C27G55T and sits alongside the Samsung Odyssey G5/G55A S27AG55, which has similar features but a different panel type. This monitor has an IPS panel and a flat screen, with a 165Hz refresh rate and VRR support in the form of native FreeSync support and G-SYNC compatibility. It's available in 27 and 32 inches, but it's limited on extra features for productivity, as it lacks any USB inputs.

Our Verdict

7.0 PC Gaming

The Samsung G50A is decent for PC gaming. It has a 165Hz refresh rate with native FreeSync support and G-SYNC compatibility to reduce screen tearing. Motion looks sharp thanks to the consistently quick response time, and it has low input lag for a responsive gaming experience. However, it has limited picture quality as blacks look gray in the dark, it lacks a local dimming feature, and highlights don't pop in HDR.

Pros
  • 165Hz refresh rate with VRR support.
  • Consistently fast response time.
  • Low input lag.
Cons
  • Low contrast ratio.
  • Small highlights don't pop in HDR.
  • Limited to DP 1.2 and HDMI 2.0 bandwidth.
6.5 Console Gaming

The Samsung Odyssey G50A 27 is okay for console gaming. Motion looks sharp thanks to its fast response time at any refresh rate, and gaming feels responsive as it has low input lag. While it supports most signals from the Xbox Series X|S and PS5, it lacks HDMI 2.1 bandwidth to take full advantage of them. It also has limited picture quality, so games don't look life-like as it has a low contrast ratio and fails to make colors look vivid.

Pros
  • Consistently fast response time.
  • Low input lag.
Cons
  • Low contrast ratio.
  • Small highlights don't pop in HDR.
  • Limited to DP 1.2 and HDMI 2.0 bandwidth.
7.9 Office

The Samsung Odyssey G5 G50A is good for office use. It has a large 27-inch screen with a 1440p resolution that help deliver clear text. It has fantastic ergonomics with a wide swivel range, which is great for sharing your screen with others. It also gets bright enough to fight glare and has good reflection handling, which is ideal if you want to use it in a well-lit room. Unfortunately, it's limited in extra features, and it lacks any USB ports.

Pros
  • Bright enough to fight glare in well-lit rooms.
  • Fantastic ergonomics.
  • Good text and image clarity.
Cons
  • Limited on extra features; no USB hub.
6.9 Editing

The Samsung Odyssey G50A is okay for content creators. The 1440p resolution helps deliver detailed images with good clarity. It has fantastic ergonomics if you need to swivel the screen to show something to a client or coworker, and it also gets bright enough to fight glare in a well-lit room.

Compared To Other Monitors

The Samsung Odyssey G5 G50A is a decent entry-level 1440p gaming monitor that offers sharp motion handling and low input great, which is ideal for any type of gamer. You'll definitely be happy with it if you're on a tight budget and want a solid gaming option, but you can also consider other models if you want extra features, like the Gigabyte M27Q P.

Make sure to check out our recommendations for the best 1440p monitors, the best gaming monitors, and the best monitors for Xbox Series X.

LG 27GP850-B/27GP83B-B

The LG 27GP850-B/27GP83B-B and the Samsung Odyssey G5 S27AG50 are both gaming monitors with similar features. They both have a 1440p resolution with native FreeSync support and a 165Hz refresh rate, but you can overclock the refresh rate to 180Hz on the LG. Motion handling is great on each, and they both have low input lag for gaming, but there are a few differences in other areas. The LG displays a wide color gamut for HDR content, but it doesn't add much because neither deliver a satisfying HDR experience. The LG also has two USB 3.0 inputs, while the Samsung has a USB input for service inputs, but the Samsung has much better ergonomics because you can swivel it.

Samsung Odyssey G5/G51C S27CG51

The Samsung Odyssey G5/G51C S27CG51 and the Samsung Odyssey G5 S27AG50 are both gaming monitors with a 165Hz refresh rate, but there are a few differences. They have different panel types, with the S27CG51 having a higher contrast ratio and the S27AG50 having wider viewing angles. The S27AG50 also has much better motion handling and even gets brighter, making it the better choice if you want to use it in a well-lit room.

LG 27GL850-B/27GL83A-B

The Samsung Odyssey G5 S27AG50 is similar for gaming to the LG 27GL850-B/27GL83A-B. The Samsung has a faster 165Hz refresh rate than the 144Hz on the LG, and it has a BFI feature that the LG doesn't have. The Samsung is also a slightly better choice for well-lit rooms because it gets brighter, and if you want to use it for co-op gaming, you can swivel its stand, which you can't do with the LG. The one difference the LG has over the Samsung is that it has USB 3.0 inputs to connect your keyboard and mouse, which you can't do with the Samsung.

Samsung Odyssey G5 C27G55T

The Samsung Odyssey G5 S27AG50 is a newer monitor than the Samsung Odyssey G5 C27G55T, but they're different monitors. The S27AG50 has an IPS panel with wider viewing angles and a flat screen, while the C27G55T has a VA panel with better contrast, and the screen is curved. The S27AG50 has much better motion handling because it has a quicker response time, and there's no black smearing like on the C27G55T. It also has a slightly higher max refresh rate. On the other hand, the C27G55T's BFI feature works at a much wider range, and it has built-in speakers, which the S27AG50 doesn't.

ASUS TUF VG27AQ

The Samsung Odyssey G5 S27AG50 and the ASUS TUF VG27AQ are both gaming monitors. The Samsung has a native 165Hz refresh rate, and while the ASUS has a native refresh rate of 144Hz, you can overclock it to 165Hz. However, motion handling is much better on the Samsung because it has a quicker response time, and it also gets brighter and has better reflection handling if you want to use it in a bright environment. As for the ASUS, it feels better built, and it has much better ergonomics because it has a wider swivel range, and you can rotate it into portrait mode in both directions.

ASUS TUF Gaming VG27AQL1A

The ASUS TUF Gaming VG27AQL1A and the Samsung Odyssey G5 S27AG50 are similar gaming monitors. They each have an IPS panel with a 1440p resolution. The Samsung has much better motion handling because it has a quicker response time at its max refresh rate and 60Hz, and it gets brighter, so it does a better job at fighting glare. The ASUS has built-in speakers and a local dimming feature, both of which the Samsung doesn't have, but the local dimming doesn't add much because it performs terribly.

Samsung Odyssey G5/G55A S27AG55

The Samsung Odyssey G5 S27AG50 is much better than the Samsung Odyssey G5/G55A S27AG55. The S27AG50 has a much better design, with a full range of ergonomic adjustments, so you can better place it in an ideal viewing position. The S27AG50 also has a much faster response time, resulting in clearer motion, and it gets a lot brighter to overcome glare.

MSI Optix MAG274QRF-QD

The MSI Optix MAG274QRF-QD and the Samsung Odyssey G5 S27AG50 are both good gaming monitors. They both have a 165Hz refresh rate, native FreeSync VRR support, a 1440p resolution, and fantastic motion handling. There are a few differences in picture quality, though; the MSI displays a wider color gamut in HDR and SDR, but that's because it over-saturates the colors, meaning some people may prefer the Samsung. The Samsung also gets brighter and has better reflection handling, so it's a better choice for well-lit rooms. On the other hand, the MSI has a better selection of inputs, such as a USB-C input and two USB inputs that you can connect your keyboard and mouse to.

Acer Nitro XV272U KVbmiiprzx

The Samsung Odyssey G5 S27AG50 and the Acer Nitro XV272U KVbmiiprzx are excellent gaming monitors with a 1440p resolution. The Acer has a slightly faster 170Hz refresh rate compared to 165Hz on the ASUS, and it has slightly quicker response times, but the motion looks fantastic on both. The Acer has much better ergonomics because you can swivel the stand a full 360 degrees. It delivers more accurate colors because it has better out-of-the-box accuracy. However, the Acer has much better reflection handling, and it gets brighter if you want to use it in a well-lit room.

Gigabyte M27Q (rev. 1.0)

The Gigabyte M27Q (rev. 1.0) and the Samsung Odyssey G5 S27AG50 are similar 1440p gaming monitors. They have similar gaming features with good motion handling and low input lag. The Samsung is better for co-op gaming because it has better ergonomics as the stand can swivel. However, the Gigabyte is better for productivity because it features a USB hub with two USB 3.0 inputs and a USB-C input, which the Samsung doesn't have.

Samsung Odyssey G7 S28AG70

The Samsung Odyssey G5 S27AG50 sits below the Samsung Odyssey G7 S28AG70 in Samsung's lineup, so they have different features. The S28AG70 is a 4k monitor with a 28-inch screen, 144Hz refresh rate, and its HDMI 2.1 inputs are better for console gaming. However, the S27AG50 has a 1440p resolution, 27-inch screen, and a faster 165Hz refresh rate. They both have a fast response time at their max refresh rate, but the S27AG50 has a faster response time at 60Hz. The S27AG50 also gets brighter and has better reflection handling, so it's a better choice for a bright room. However, the S28AG50 displays clearer text thanks to the higher pixel density, and it displays more accurate colors.

Samsung Odyssey G3 S24AG30

The Samsung Odyssey G5 S27AG50 is much better for gaming than the Samsung Odyssey G3 S24AG30 as it's a higher-end monitor and has more features. The S27AG50 has a higher 165Hz refresh rate with much better motion handling, and it gets much brighter in SDR. The S27AG50 has wider viewing angles thanks to the IPS panel, and it supports HDR, which the S24AG30 doesn't, but it doesn't add much because the picture quality in dark scenes isn't good. The S27AG50 is also larger, while the S24AG30 is a smaller 24-inch screen with a 1080p resolution, but it has a better contrast thanks to the VA panel.

Samsung Odyssey G7 C32G75T

The Samsung Odyssey G7 C32G75T and the Samsung Odyssey G5 S27AG50 are both good gaming monitors. While they have a few similar features, they're different in a few areas. The C32G75T has a higher 240Hz refresh rate compared to 165Hz on the S27AG50, and it has a curved screen with a VA panel and a high contrast. The S27AG50 has an IPS panel with wider viewing angles, and it has a flat screen. Motion handling is fantastic on each, but there's less black smearing on the S27AG50. The C32G75T has a local dimming feature, but it performs terribly, and even though it displays a wider color gamut, its HDR performance isn't much better.

Gigabyte M27Q P

The Samsung Odyssey G5 S27AG50 and the Gigabyte M27Q P are both impressive gaming monitors. They have similar specs with a 1440p resolution and 165Hz native refresh rate, but the Gigabyte has an overclock feature to go up a bit to 170Hz. However, the Samsung monitor still has a faster response time at any refresh rate, leading to less motion blur, and this model has lower input lag with 60Hz signals. The main advantage the Gigabyte has is that there are a few office-oriented features, like a USB-C port and a KVM switch. The Gigabyte also displays a wider range of colors with better accuracy, especially in HDR.

The HDR brightness is decent. It gets brighter than in SDR, but small highlights don't pop against the rest of the image. The PQ EOTF tracking is decent, but mid-tones are overbrightened until there's a sharp cut-off at the peak brightness, so at least it lets highlights get the brightest they could without any tone mapping. These results are in the 'HDR Dynamic' Picture Mode with the Brightness at its max.

The accuracy before calibration is decent. The sRGB mode locks the colors to the sRGB colors space, so they don't look oversaturated. However, some colors are still off, and the white balance is terrible. The color temperature is also much colder than the 6500K target, giving the image a blue tint. Gamma doesn't follow the target sRGB curve well either, as most scenes are too bright. The sRGB mode also locks some picture settings, so if you want more customizability, you'll need to use another picture mode that has oversaturated colors.

The Samsung Odyssey S27AG50 has very good motion handling across its refresh rate range. It's extremely consistent at any refresh rate, which is great, but you can't use any of the Response Time overdrive settings with VRR enabled.

The refresh rate compliance is good. While its response time isn't fast enough to make full color transitions before the monitor draws the next frame at high frame rates, it's better than other LED-backlit monitors, and it improves at 60Hz.

The CAD at the max refresh rate of 165Hz is very good. Motion looks sharp without much blur, but you can only use the Response Time overdrive settings if you disable Adaptive Sync in the OSD. In that case, the 'Faster' overdrive setting provides the best motion, but it has some inverse ghosting, so 'Standard' is better if that bothers you.

The CAD at 120Hz is good. Motion is sharp, and unlike at the max refresh rate, the recommended overdrive setting of 'Standard' doesn't have any noticeable inverse ghosting. These results are with the Refresh Rate in the OSD set to 120Hz, as setting it to 165Hz causes the screen to still refresh at 165Hz.

There's an optional backlight strobing feature, commonly known as black frame insertion (BFI). It only works when you enable the 'Extreme (MBR)' Response Time setting, and you can't use it at the same time as VRR. It works within a narrow range, and although you can enable it as low as 60Hz, it only flickers at 120Hz and causes image duplication.

The Samsung Odyssey S27AG50 has some VRR flicker with changing frame rates in dark scenes that are hard to see in the video, but it's still visible in person. That said, it isn't overly distracting either, and it doesn't happen if you have a consistent frame rate.

The Samsung G50 has incredibly low input lag for a responsive gaming experience. However, you have to make sure the PC and the monitor's refresh rates are the same for the lowest input lag. With the monitor set to 165Hz, and our test PC at 60 fps, the input lag was 22.9 ms, but setting the monitor to 60Hz brings it down to 8.9 ms. You can also enable VRR to achieve this low input lag.

This monitor works as expected with the PS5 as it lacks HDMI Forum VRR and HDMI 2.1 bandwidth. That said, you need to disable Adaptive Sync in the monitor's OSD if you want to get a downscaled 4k signal.

This monitor can't take full advantage with the Xbox Series X|S as it's limited to HDMI 2.0 bandwidth. You need to disable Adaptive Sync to get a downscaled 4k signal, which is disappointing because the Xbox Series X|S only supports HDR in 4k. This means that you can't get VRR and HDR at the same time.

macOS Compatibility

This monitor works well for the most part with macOS. VRR works well in-game but flickers a bit when you're not in a game. HDR technically works, but it doesn't look good, so you're better off leaving it disabled. On the other hand, there are no sleep mode issues, and windows return to their original position when you wake up your computer.

There aren't too many extra features, but it still has:

  • Black Stabilizer: Adjusts the gamma so you can see opponents easier in dark games
  • Crosshair: Adds a virtual crosshair on the screen that your system won't detect.
  • Frame Rate Counter: Displays the current frame rate of your PC.
  • Ultrawide Game View Mode: This changes the aspect ratio to 21:9 to simulate an ultrawide screen. It changes the resolution to 2560x1080, and you can't use VRR with it, but you still get the full refresh rate range.
