The Samsung Odyssey G7/G70B S32BG70 is a 32-inch, 4k gaming monitor that's also available in a 28-inch size, but it's a different product that doesn't perform the same. It's a newer version of the Samsung Odyssey G7 S28AG70 with many of the same features, including HDMI 2.1 bandwidth for console gaming and FreeSync variable refresh rate (VRR) support with G-SYNC compatibility. Unlike other models in the Odyssey G7 lineup released in 2022, this one is limited to a 144Hz refresh rate and doesn't feature Mini LED backlighting like the higher-end Samsung Odyssey Neo G7 S32BG75. However, it's a unique gaming monitor because it features Samsung's proprietary Tizen OS smart platform built-in, letting you stream content without needing a PC, and it has extra connectivity options like built-in Wi-Fi and Bluetooth support.

Our Verdict

8.2 Mixed Usage

The Samsung G70B is great for most usages. It's excellent for gaming thanks to its quick response time, low input lag, VRR support, and HDMI 2.1 bandwidth for console gaming. It's also impressive for work use as it has a large 32-inch screen with a 4k resolution for sharp details, and it delivers accurate colors if you want to use it for photo editing. It's good for watching videos with friends as it has wide viewing angles and fantastic ergonomics. However, its picture quality is disappointing in dark rooms due to its low contrast ratio, and it doesn't get bright enough to make highlights truly pop in HDR.

Pros
  • 4k resolution for sharp details.
  • Performs well in bright rooms.
  • Fantastic ergonomics.
Cons
  • Low contrast ratio.
  • Terrible local dimming feature.
8.4 Office

The Samsung G70B is impressive for office use. The large 32-inch screen lets you open multiple windows at once, and the 4k resolution helps deliver sharp text. It also gets bright enough to fight glare if you want to use it in a well-lit office, and the reflection handling is very good. Lastly, it has wide viewing angles and fantastic ergonomics, making it easy to adjust to an ideal position if you need to share your screen with someone else.

Pros
  • Large screen size.
  • 4k resolution for sharp details.
  • Performs well in bright rooms.

8.6 Gaming

The Samsung G70B is excellent for gaming. It has FreeSync support with G-SYNC compatibility to reduce screen tearing, and it has low input lag and a quick response time for a smooth and responsive gaming experience. It's designed with console gamers in mind, as it has HDMI 2.1 bandwidth that lets you take full advantage of current-gen consoles. Unfortunately, it's disappointing for dark room gaming due to its low contrast, which makes blacks look gray in the dark.

Pros
  • 4k resolution for sharp details.
  • HDMI 2.1 bandwidth for console gaming.
  • Low input lag in Game Mode.
  • Fast response time at any refresh rate.
  • FreeSync VRR and G-SYNC compatibility.
Cons
  • Low contrast ratio.
  • Terrible local dimming feature.
7.7 Media Consumption

The Samsung G70B is good for media consumption. It has a built-in smart system that lets you stream content without a PC. It's good if you want to watch content in a bright room or with friends, as it gets bright enough to fight glare and has wide viewing angles. It also delivers sharp details thanks to its 4k resolution. However, it performs worse in dark rooms because blacks look gray due to its low contrast ratio, and its edge-lit local dimming feature doesn't do much to improve the contrast.

  • Performs well in bright rooms.
  • Fantastic ergonomics.
  • Excellent color accuracy.
Cons
  • Limited extra productivity features.
7.1 HDR

The Samsung G70B is alright for HDR. It displays a wide range of colors in HDR and makes most colors look vivid, but it doesn't get bright enough to make small highlights stand out against the rest of the image. It also has a low contrast ratio, and while it has an edge-lit local dimming feature, it doesn't do much to improve the contrast, and blacks look gray in the dark.

Differences Between Sizes And Variants

We tested the 32-inch Samsung G70B, which is also available in a 28-inch size. Although the 28-inch model has the same features, it's a different product, so our results aren't valid for it. This monitor is a newer version of the Samsung Odyssey G7 S28AG70, and it's part of Samsung's Odyssey G7 lineup that includes a variety of models; you can see the differences between them below.

Compared To Other Monitors

The Samsung G70B is an excellent 4k gaming monitor with fantastic motion handling and HDMI 2.1 bandwidth for console gaming. It offers better value than other 4k options like the LG 32GQ950-B and the Sony INZONE M9, but it has worse picture quality than the Samsung Odyssey Neo G7 S32BG75 because it lacks Mini LED backlighting. While it's a better choice than some more expensive models, you can still find the Gigabyte M32U for less, and it has more productivity features that make it versatile, like a USB-C input and KVM switch.

Also see our recommendations for the best 4k 144Hz monitors, the best 4k gaming monitors, and the best monitors for Xbox Series X.

Samsung Odyssey Neo G7 S32BG75

The Samsung Odyssey Neo G7 S32BG75 is a higher-end version of the Samsung Odyssey G7/G70B S32BG70, so it's better overall. The main difference is that the Neo G7 has a VA panel with Mini LED backlighting, resulting in a much better contrast and local dimming feature. It also gets brighter in HDR, particularly with smaller highlights. On the other hand, the G70B has better motion handling as there's less overshoot.

Samsung Odyssey G7 S28AG70

The Samsung Odyssey G7/G70B S32BG70 is the newer version of the Samsung Odyssey G7 S28AG70 with many of the same features and performance. The BG70 is available in 28 and 32-inch screen sizes, while the AG70 is available in just a 28-inch screen size. The BG70 improves in a few areas, like peak brightness, reflection handling, and motion handling. It also has a built-in Tizen OS smart platform, which the AG70 doesn't have, letting you stream content without a PC.

Gigabyte M32U

The Samsung Odyssey G7/G70B S32BG70 and the Gigabyte M32U are comparable 4k, 32-inch monitors with a 144Hz refresh rate. They both deliver excellent gaming performance, but the Samsung monitor has better motion handling. However, the Gigabyte is more versatile for other uses as it has a USB-C port and a KVM switch for productivity.

LG 32GQ950-B

The Samsung Odyssey G7/G70B S32BG70 and the LG 32GQ950-B are both excellent 4k gaming monitors. They each have a 144Hz refresh rate, but the LG is overclockable to 160Hz for a slightly smoother feel. The LG gets much brighter in HDR to make highlights pop, but if you want to use the monitor in a well-lit room, the Samsung has better reflection handling. Also, the Samsung has better motion handling with 60Hz signals, but the LG has lower input lag at 60Hz for a more responsive feel.

Gigabyte M28U

The Samsung Odyssey G7/G70B S32BG70 and the Gigabyte M28U are both great 4k, 144Hz monitors. They share many similarities, including a fast response time, and while the Samsung has a faster response time at 60Hz, the Gigabyte has lower input lag with 60Hz signals. The Samsung also gets brighter if you want to use it in a well-lit room, but the Gigabyte has more work-oriented features like a USB-C input.

Gigabyte M32UC

The Gigabyte M32UC and the Samsung Odyssey G7/G70B S32BG70 are both great 4k, 32-inch monitors with a few differences. They have different panel types, so while the Samsung has wider viewing angles, the Gigabyte has a better contrast for deeper blacks. The Gigabyte also gets brighter both in SDR and HDR. However, in terms of gaming, the Samsung monitor has better motion handling thanks to its quicker response time.

Sony INZONE M9

The Sony INZONE M9 and the Samsung Odyssey G7/G70B S32BG70 are both excellent gaming monitors with many of the same features. The Samsung monitor delivers better motion handling, especially with lower-frame-rate games, but the Sony has lower input lag with 60 fps sources. The Samsung also has much better ergonomics, making it easier to adjust to an ideal viewing position. On the other hand, the Sony looks better in HDR thanks to its higher peak brightness, but both monitors have low contrast.

The build quality is great. It's made of high-quality plastic that feels sturdy, and it's well put-together. The stand supports the screen well when you adjust it, and even though the display wobbles a bit when you shake the table, this isn't a problem unless you have an unstable desk. It does have a dead pixel near the center, which you can see in the Black Uniformity photo, but it isn't a major concern, and it's hard to notice.

Contrast With Local Dimming

The Samsung Odyssey G70B has a mediocre contrast ratio, making blacks look gray next to bright objects. Although it has a local dimming feature, it doesn't do much to improve the contrast, as most content causes all zones to turn on.

Edge

The edge-lit local dimming feature is terrible. It has 32 zones, and all of them turn on with the majority of content, meaning it doesn't improve the contrast at all, even with Local Dimming set to 'High'. When zones remain off, there's still distracting blooming around bright objects, and the uniformity is awful, as you can see backlight bleed. Although the dimming zones keep up with fast-moving objects, there's a noticeable backlight flicker whenever a small object transitions between zones. Overall, the feature does little to improve the picture quality in dark scenes and make blacks deeper.

It performs equally as badly even when using the built-in applications, although the zones are a bit less sensitive to light in that scenario, so they don't turn on as often.

The HDR peak brightness is okay, but it doesn't get bright enough to make small highlights stand out against dark backgrounds. The EOTF doesn't follow the target PQ curve well with bright scenes, meaning the image looks darker than it should.

These results are in Game Mode with the Picture Mode set to 'Custom', Local Dimming on 'High', and the HDR10+ Gaming setting in HDR Tone Mapping set to 'Advanced'. The EOTF performs the same even if you set HDR10+ Gaming to 'Basic'. You can also enable Game HDR if you want a brighter image, but then the EOTF is too bright, as you can see here.

The Samsung Odyssey G70B has excellent accuracy before calibration. Setting the Color Space setting to 'Auto' instead of its default of 'Native' locks the colors to the sRGB color space, and you can still change other settings as you wish. Most colors are accurate, and the white balance is only slightly off. The color temperature is a bit on the warm side, resulting in a reddish tint, and the gamma doesn't follow the sRGB target curve perfectly, so most scenes are too dark, while bright scenes are too bright.

Luckily, FreeSync and the G-SYNC compatibility work over its entire refresh rate range with both HDMI and DisplayPort connections. However, the VRR support is unstable at times, as it would cause the screen to turn black or flash on and off when switching applications, as if it was resetting the handshake. Even while using Adobe Premiere and Lightroom, the same thing would occur, and the screen would turn on and off while using the applications. If you're just in the desktop, it's best to disable VRR because of this issue and stay in Game Mode for low input lag. It's better to only enable VRR for gaming.

The Samsung Odyssey G70B is completely flicker-free with the local dimming disabled, which helps reduce eye strain. However, the flicker is over 1,000Hz when you enable local dimming, and you can see the graph here.

Other Samsung monitors, like the Samsung Odyssey G7 C32G75T, have flicker and scanline issues, especially with VRR enabled and in darker scenes. We didn't notice any of the same flicker issues, but you can still see the same scanline issues with specific test patterns, as seen here. However, this is a very specific example and isn't noticeable with real content.

The Samsung Odyssey G70B has low input lag for a responsive feel with high-frame-rate signals like at 144Hz and 120Hz. While the input lag increases with 60Hz signals, it's still low enough for casual gaming, but you'll notice delay with BFI enabled. For the lowest input lag you need to make sure you have the input label set to 'PC' and you're in Game Mode. With these settings, you can only send a fixed 144Hz refresh rate with VRR disabled, so we had to use a workaround to measure the input lag at 120Hz and 60Hz while still in Game Mode with the 'PC' input and VRR disabled.

The input lag changes depending on the settings you use, and you can see the different results below. Additionally, if you disable Game Mode you can't send a 144Hz signal.

The VRR Control setting is a feature Samsung implemented to help reduce the flicker seen on past models, but since there isn't noticeable flicker on this monitor and it increases the input lag, it's better to disable it.

The Samsung Odyssey G70B doesn't have any compatibility issues with the PS5, and it works perfectly with it. The Tizen OS knows it's connected to a PS5 and automatically switches the input label to 'Game Console'. You need to make sure it does because you can't send a fixed 120Hz or 60Hz signal when the input label is still set to 'PC'.

As both HDMI ports support the full 48 Gbps bandwidth of HDMI 2.1, your graphics card doesn't need to use compression to send high-bandwidth signals, like 4k @ 144Hz. Also, the monitor has an RJ45 Ethernet port, so you can connect it directly to the Internet for streaming. It also supports other connectivity options you'd normally find on a TV, like Wi-Fi, Bluetooth, and HDMI ARC if you want to connect a soundbar.

macOS Compatibility

The Samsung G70B works well with recent M1 MacBooks. With macOS only, HDR doesn't work while in Game Mode, so you have to choose between a 144Hz signal in SDR with low input lag or a 120Hz signal in HDR with higher input lag. Still, if you want to watch videos and you don't mind the higher input lag, HDR looks good. There aren't any problems with VRR either. While windows return to their normal position after waking up the laptop from sleep, they don't return to their position when you open the lid after closing it, which is a common issue when using a DisplayPort to USB-C adapter.

This monitor comes with Samsung's proprietary Tizen smart platform built-in, unlike older Samsung gaming monitors. It lets you stream content directly from the monitor without a computer and has built-in apps like Netflix, Amazon Prime Video, Disney+, etc. You can read more about all its features in the Smart Features section of the Samsung QN90B QLED TV review. Although it has a Multi-View feature, it isn't a true Picture-by-Picture/Picture-in-Picture mode because you can't view images from two sources at once, and instead, you can only split the screen between one external source and one built-in app.

The Samsung Odyssey G70B has other gamer-oriented features, including:

  • Core Lighting: Controls the RGB lighting on the monitor.
  • Game HDR: Helps increase the perceived brightness of the image in HDR.
  • Game Mode: Mode needed for the lowest input lag possible.
  • HDR10+ Gaming (HDR Tone Mapping): Adjusts the colors in HDR to match the creator's intent.
  • Local Dimming: Setting used to control the monitor's local dimming feature. You can set it to 'Off', 'Low', 'Standard', or 'High', depending on your personal preference.
  • Ultrawide Game View: Simulates a 21:9 aspect ratio for ultrawide gaming; you'll see black bars on the top and bottom.
  • Virtual Aim Point: Adds a virtual crosshair on the screen that your PC won't detect.
  • VRR Control: This feature is meant to reduce flicker with VRR enabled, which is a problem with other Samsung monitors, but not so much this one.

Features
On-Screen Display (OSD)

Unlike other Samsung monitors, the menu uses the Tizen OS interface and looks much like the menu on TVs. You can read more about the settings with TVs here.
