The Samsung Odyssey G9 almost has it all – image quality is superb, it’s packed with features and it has a stunning form factor. The aspect ratio and price mean it won’t be for everyone, but it’s a deeply impressive bit of tech.


  • Fantastic widescreen design
  • Superb 240Hz AMD FreeSync
  • Great image quality in SDR and HDR modes


  • Super-wide design won’t suit everyone
  • Needs some more ports
  • Underwhelming lighting

Key Specifications

  • Review Price: £1280
  • 49in diagonal, 5120 x 1440
  • VA panel
  • Refresh rate: 240Hz
  • 1ms response time
  • AMD FreeSync Premium Pro

  • Weight: 16.7kg

The Samsung Odyssey G9 is one of the most ambitious gaming monitors on the market.

The 49-inch diagonal dominates any desk, and it’s paired with a 32:9 aspect ratio, a vast 5120 x 1440 resolution, a 240Hz refresh rate and the 1000R curve that’s also included on the smaller G7.

It’s a huge amount of technology, but it does mean the G9 is expensive – Samsung’s latest costs a whopping £1280. Is it worth the steep price?


  • An obscenely wide monitor with a 32:9 aspect ratio
  • Lack of USB Type-C is a notable omission 
  • Odyssey G9 weighs a hefty 16.7kg

The super-wide design is brilliant for racing games, and it works well in RPG, strategy and adventure games; titles that benefit from expansive views.

It’s great for productivity, especially if you work in large horizontal timelines, and it can easily replace a multi-monitor setup. The 1000R curve improves immersion and viewing angles when compared to conventional 1800R designs too.

Bear in mind that the 32:9 form factor may not always work well. In FPS games you’ll need more vertical space, and lots of esports games don’t really benefit from the extra width. You’ll also get black bars down the sides when watching movies.

The G9 mixes glossy white plastic with rear-mounted RGB LEDs and a stylish stand. It’s got 120mm of height adjustment, which is good for a super-wide panel, and it has tilt and swivel options. Build quality is rock-solid, and the panel has two DisplayPort connectors, an HDMI port and two USB 3.0 ports.

Samsung Odyssey G9 07

As with the G7, though, the G9 does have physical disappointments. There’s no USB Type-C or Thunderbolt, and the lighting is underwhelming – not very adjustable and impossible to see from the front.

The weight of 16.7kg is necessarily hefty, and the headphone holder is flimsy and difficult to reach. Setting this screen up can be inconsistent: the OSD is excellent but a proliferation of screws means the G9 is awkward to build.

Image Quality

  • Odyssey G9 pixel density comes in at 109ppi. 
  • Resolution peaks at 5120 x 1440
  • Display is capable of a 240Hz refresh rate 

The generous 5120 x 1440 resolution delivers a density level of 109ppi, which is easily good enough for gaming. Only 4K screens will be sharper. A trickier issue will be the sheer number of pixels produced by this panel – the G9 uses almost as many as a 4K screen, so you’ll need a powerful graphics card.

You’ll also need a powerful GPU to take advantage of the 240Hz refresh rate, although that’s a welcome addition here. It works with AMD and Nvidia graphics cards and delivers butter-smooth performance in the fastest games thanks to the latest syncing technology. It did however exhibit a little bit of ghosting and modest halo effects, but it’s better than most of its contemporaries and most people just won’t notice. Similarly, there’s a tiny bit of backlight bleed but it’s barely noticeable.

Elsewhere, the Samsung uses DisplayHDR 1000, which is another area where this screen outpaces its rivals, and the underlying panel is a 10-bit VA display with a 1ms response time.

Out of the box, the G9’s brightness and black points of 354 and 0.18 nits deliver a contrast ratio of 1967:1. That’s far better than any IPS display, and it means games have huge punch, vibrancy and depth. The great contrast is paired with a reasonable Delta E of 2.73 and a colour temperature of 6435K, so colours are easily good enough for gaming. The G9 maintained these impressive results with the brightness reduced to a more conventional level, and its uniformity is great – a backlight strength deviation of just 11% on a 49in widescreen is tremendous.

Samsung Odyssey G9 05

The G9 rendered 99.7% of the sRGB colour gamut and 97% of the DCI-P3 space, and its HDR performance was impressive. It peaked at around 1000 nits of backlight strength and delivered a black point of 0.05 nits, with both figures adhering to DisplayHDR 1000 standard.

These figures helped the screen deliver a noticeable increase in depth and vibrancy in HDR content. It’s better than most gaming screens in this regard, although the inclusion of ten local dimming zones is disappointing, meaning the HDR lacks nuance when compared to the best TVs.

You should buy it if…

  • Budget isn’t an issue
    Coming in at £1280, this is a supremely expensive piece of kit that is clearly aimed at designers and gamers who are willing to pay the extra price. It’s arguably worth the investment, but more casual consumers can definitely look elsewhere.
  • You want a wide and colourful display
    You’ve probably figured out how obscenely massive the Samsung Odyssey G9 is by now, requiring ample amounts of desk space to even be used. If such a display will prove beneficial in day-to-day usage, the G9 could be right up your street.
  • Refresh rates mean the world to you
    The Samsung Odyssey G9 supports a 240Hz refresh rate, which is absolutely overkill for the majority of users. However, those wanting razor-sharp gaming performance and crisp and clear visuals for video editing will absolutely adore such a feature.

You shouldn’t buy it if…

  • Ports are important to you
    The lack of a USB-C and Thunderbolt port in the Odyssey G9 feels like a huge omission, especially with so many modern devices supporting such inputs. Without them, the capabilities of this monitor are arguably shrunk in some major ways.
  • It is too expensive
    This monitor is a serious investment, and one that only hardcore gamers and professionals could ever justify. There are cheaper and arguably more sensible options to consider if price ends up being a major barrier.
  • You want the best lighting
    The lighting in the Odyssey G9 is a bit uninspired, even if only the most eagle-eyed of users will be able to point out such flaws. But given the cost, such shortcomings are harder to overlook.

Jargon buster

Refresh Rate

The number of times the screen refreshes itself per second.


‘Framerate per second’ indicates how many images are shown within one second. The higher this figure, the smoother in-game motion will appear. Powerful discrete GPUs are far more likely to offer higher framerates compared to integrated graphics housed inside processors.

Colour Gamut

The range of colours an output device is capable of reproducing.


The brightness level of a display. 300 nits is regarded as the minimum target for high-end screens.
