Color Accuracy

The Samsung M80D is a 32-inch 4k smart monitor. A replacement for the Samsung Smart Monitor M8/M80C S32CM80, it's similar to the lower-end Samsung M70D and competes against other smart monitors such as the LG MyView Smart Monitor (32SR85U) and the ASUS ZenScreen Smart Monitor MS27UC. Like other smart monitors, it includes a remote with voice control, a smart OS like you'd normally find on a TV, and integrated speakers. It also has some extra features, such as Picture-in-Picture/Picture-by-Picture mode for displaying multiple inputs at the same time, as well as some gaming features, such as Virtual Aim Point and Minimap Zoom.

Our Verdict

6.5 PC Gaming

The Samsung M80D is okay for PC gaming. Fast-moving objects look quite blurry, so it's not a good choice for games with a lot of motion. While it displays HDR colors decently, it doesn't have local dimming and doesn't get bright enough for highlights to pop, though it's bright enough to overcome glare. Though it's not a monitor to buy for gaming, it works decently for slower, text-heavy games like turn-based strategy games, thanks to its superb text clarity.

Pros
  • High native contrast ratio.

Cons
  • Disappointing motion handling.

  • 60Hz refresh rate and no VRR.

  • No local dimming feature.

  • Highlights don't pop against the rest of the image.

4.9 Console Gaming

The Samsung M80D is disappointing for console gaming. It's limited to a 60Hz refresh rate, and fast-moving objects look blurry. As a result, it's not a good choice for FPS and action RPG games. However, while it doesn't get bright enough for highlights to pop, it's bright enough to overcome glare. Additionally, it has sharp text, so it works decently if you plan on playing turn-based strategy or other slower games.

Pros
  • Low input lag.

  • High native contrast ratio.

Cons
  • Disappointing motion handling.

  • 60Hz refresh rate and no VRR.

  • Limited support for console features.

  • No local dimming feature.

  • HDMI 2.0 Bandwidth.

  • Highlights don't pop against the rest of the image.

8.3 Office

The Samsung M80D is great for office use. Its large 32-inch screen makes it easy to multitask, and its 4k resolution ensures sharp text. It also gets bright enough to overcome glare, so there's no issues using it in a well-lit room. While it has good ergonomics that make it easy to adjust for individual use, without swivel adjustments and wide viewing angles it's difficult to share the screen with someone sitting next to you.

Pros
  • Fantastic text clarity.

  • Bright enough to fight glare.

  • Good individual ergonomics.

Cons
  • No swivel adjustments.

  • Narrow viewing angles.

7.7 Editing

The Samsung M80D is good for content creation. It has accurate colors before calibration, but calibrating it still provides the best accuracy. On the plus side, its large 32-inch screen is big enough for multitasking, and its high resolution and high pixel density ensure a sharp image. It also has good ergonomics, but it doesn't offer swivel adjustments, and because it has narrow viewing angles, it's difficult to share your screen with a coworker or client.

Pros
  • Fantastic text clarity.

  • Bright enough to fight glare.

  • High native contrast ratio.

  • Good individual ergonomics.

Cons
  • No swivel adjustments.

  • Narrow viewing angles.

7.6 Brightness

The Samsung M80D has good brightness, as it gets bright enough to fight glare in well-lit rooms. While it still gets bright in HDR, highlights don't pop against dark backgrounds.

Pros
  • Bright enough to fight glare.

Cons
  • Highlights don't pop against the rest of the image.

5.4 Response Time

The Samsung M80D has a poor response time, and there's noticeable smearing and motion blur with fast-moving objects.

Pros
Cons
  • Disappointing motion handling.

6.0 HDR Picture

The Samsung M80D has acceptable HDR picture quality. HDR colors look decently vivid, and it displays darker colors fairly well. It also has excellent contrast and fairly deep blacks are visible in a dark room. However, it doesn't have local dimming to improve this performance.

Pros
  • High native contrast ratio.

Cons
  • No local dimming feature.

8.3 SDR Picture

The Samsung M80D has great SDR picture quality. It displays a wide range of colors, and it displays fairly deep blacks next to bright highlights.

Pros
  • High native contrast ratio.

  • Displays wide range of colors.

Cons
8.3 Color Accuracy

The Samsung M80D has great color accuracy. Colors are quite accurate even before calibration, but you still need to calibrate it for the best accuracy.

Pros
  • Accurate colors before calibration.

Cons
  • Full calibration required for best accuracy.

Differences Between Sizes And Variants

We tested the 32-inch Samsung M80D, which is the only size available. It replaces the Samsung Smart Monitor M8/M80C S32CM80 and sits above the Samsung Smart Monitor M7/M70D, which is available in 32 and 43-inch sizes but doesn't come with all the M80D's features, such as a webcam. The M80D is only available in one color. You can see how these monitors differ below:

ModelColors AvailableSizeWebcam Included
M80DWhite32"Yes
M70DBlack32" and 43"No

Our unit's label indicates it was manufactured in May 2024. We tested it with firmware 1110.

Compared To Other Monitors

The Samsung M80D is a 4k, 60Hz smart monitor. It's ideally suited to people who don't have room for a full TV but still want a smart TV experience, including integrated apps, a remote with voice control, and even a bundled webcam. If you're looking for an all-in-one solution with a large screen and sharp text and plan to use the monitor mostly for doing work and watching content, it's a great choice at its sale price. However, it's not a great choice if you plan to game, as it's limited to a 60Hz refresh rate, and fast-moving objects look blurry. Additionally, while it's decent for watching content, its highlights don't get bright enough to pop in HDR. If you don't need a webcam and are looking for something a bit cheaper with similar performance, the Samsung Smart Monitor M7/M70C S32CM70 is a great option. Additionally, if the M80D isn't on sale and you don't need a smart system or remote, the Acer Nitro XV275K P3biipruzx is an outstanding alternative with far better picture quality, brighter highlights, and superior gaming performance.

See our recommendations for the best 32-inch monitors, the best multimedia monitors, and, if you're interested, the best budget TVs.

Samsung Smart Monitor M8/M80C S32CM80

The Samsung Smart Monitor M8/M80C S32CM80 and the Samsung Smart Monitor M8/M80D S32DM80 are extremely similar 32-inch smart monitors. While the M80C has slightly better reflection handling, the M80D was released more recently and may receive smart OS updates longer. Given their similarities you may prefer to choose whichever one costs less.

Samsung Smart Monitor M8 S32BM80

The Samsung Smart Monitor M8 S32BM80 and the Samsung Smart Monitor M8/M80D S32DM80 are similar 32-inch smart monitors. The M80D is the better option for most people, as it gets brighter in HDR, has more accurate colors, and was released more recently, and therefore may receive updates to its smart OS for longer. However, the M8 generally has similar performance, and you may prefer it if you can find it for less.

Samsung Smart Monitor M7/M70C S32CM70

The Samsung Smart Monitor M7/M70C S32CM70 and the Samsung Smart Monitor M8/M80D S32DM80 are similar 32-inch smart monitors. For most people, the M80D is a better option, as it gets brighter in HDR, includes a webcam, and was released more recently and may receive smart OS updates longer. However, if you don't need a webcam you may prefer the M70C's lower cost.

Acer Nitro XV275K P3biipruzx

The Acer Nitro XV275K P3biipruzx and the Samsung Smart Monitor M8/M80D S32DM80 are both 4k monitors. The Samsung is a better choice if you want a monitor that can double as a TV, as it has a smart OS with integrated apps and a remote with voice control. It's also a better choice if you prefer a larger screen. However, the Acer is a better option for gaming, as it has far better motion handling. It's also better if you care about picture quality, as its highlights get bright enough to pop, and it has more vivid colors.

The Samsung M80D has a simple design with thin bezels on three sides and a flat, square-based stand. It has a sensor for the remote on the bottom right side, and it comes with a camera that attaches to the back. One thing to note is that its body color is more of an off-white than a pure white.

Settings:

The HDR brightness is decent. While it gets bright enough to overcome glare, highlights don't pop. Its PQ EOTF tracking also has a slow roll-off near its peak brightness, so highlights don't get as bright as they could with Windows. However, this roll-off is helpful when using the TV's smart OS apps, as in that situation, it preserves detail in very bright scenes.

When PC Mode is off, the brightness varies depending on the Picture Mode you choose, as you can see below:

The accuracy before calibration is great. That said, while there are minimal issues with color, its white balance is only decent, and its color temperature is too cool, resulting in a blue tint. Additionally, gamma doesn't follow the target sRGB curve, as dark parts of scenes are too dark and brighter parts of scenes are too bright. While there isn't a dedicated sRGB mode, setting Color Space to 'Auto' locks colors to the sRGB color space.

The Samsung M80D works well with macOS. There aren't any issues, and if you're using a MacBook, windows move to the screen when you close the lid, and they return to their original position when reopening the lid or waking the laptop up from sleep. HDR looked normal on HDMI and DisplayPort.

As a smart monitor, the Samsung M80D has many extra features related to its Tizen OS smart platform. The interface is user-friendly and has a number of apps you can download. It's the same platform as on their TVs, which you can read more about here. As mentioned in Controls, the remote gives you access to Bixby and Alexa voice assistants, and you can also control other smart devices in your house. 

It has a number of other features beyond its smart platform functionality. Its Multi View feature lets you view images from two external sources simultaneously, though you need to be signed in to a Samsung account to do this. It also comes with a webcam with decent video quality. Additionally, it comes with built-in speakers.

Besides the features you get with the smart platform, it has a few extra gaming features, like Virtual Aim Point for a virtual crosshair and Minimap Zoom, so you can zoom in on specific areas of your screen during gaming. Additionally, this monitor has Game Motion Plus, which helps improve motion in games with lower frame rates.
