About this deal

The Odyssey G7 S28 also does not clamp the wide color gamut down to sRGB or Rec.709 by default, so there is a bit of saturation for everyday SDR content like YouTube videos. I wouldn't describe it as significant oversaturation, but it's not accurate going on the deltaE results from our testing. It’s a shame that many aspects of the G70A feel like afterthoughts, particularly given that Samsung is evidently capable of doing better. These missteps aren’t enough to drastically damage the overall rating – after all, panel performance is by far the most crucial element of any monitor – but if you’re a next-gen console gamer, I’d lean towards the sturdy and equally well-specified Asus TUF Gaming VG28UQL1A. If you’re a PC gamer, meanwhile, the original Odyssey G7 still reigns supreme. Seize winning control. The incredibly-low 2ms input lag brings never-before-experienced response accuracy to catch notoriously-agile enemies. It's so fast, that action begins instantly when you turn on the screen, with virtually no delay between your peripherals and the game. As always our full calibration results after using Portrait Display's Calman software are very good, especially for sRGB where there are no lingering issues. The only main problems were for the P3 color space, the S28 can't fully cover the P3 gamut, so performance at the top end is still off where it should be. This limits the versatility of the display as a monitor for creators using P3, but it's still fine for content consumption. The Odyssey G7 S28 is one of several new generation 4K 144Hz IPS displays for gaming, mirroring the specs of popular monitors such as the Gigabyte M28U, and the panel used here appears to be the same model from Innolux.

Colors were vibrant and beautiful, and HDR – while likely not on par with the TV in your living room – is still worth using in games that support it, for those extra highlights and more accurate colors (since SDR will be a tad oversaturated on wide gamut displays like this). Shadow of the Tomb Raider is still one of my favorite examples of HDR done well, whether you’re in the colorful Peruvian jungle or watching light stream through a hole in the wall of a dark cave. SDR brightness is mediocre, topping out at just 313 nits. This should still be fine for most use cases, but those in really bright environments may not find that to be enough. Minimum brightness is good though, sufficient for use in dark environments.The contrast ratio I recorded with my Odyssey G7 S28 unit was very good for an IPS monitor, at 1160:1, better than the Gigabyte M28U and especially Asus VG28UQL1A. This panel clearly has some variance to it, so perhaps don't expect every model to come with this contrast ratio.

You can adjust the overdrive when the FreeSync option is disabled in the OSD, but I don't think any of those settings are relevant.When compared to other monitors showing their best performance at their highest refresh rate, the G7 S28 performs as expected. It's slightly slower than the two other display's we've tested to use the same Innolux panel, the Gigabyte M28U and the Asus VG28UQL1A, but it also has lower overshoot than those displays.

Looking at response times, the Odyssey G7 S28 is similar to other Odyssey monitors in that you cannot adjust the overdrive settings when adaptive sync is enabled. The vast majority of buyers will be using adaptive sync with this display when hooked up to a PC, so we're only going to test this mode. The new Odyssey G7 brings to the table a 28-inch 4K 144Hz IPS panel aimed at gamers. It's called the LS28AG700 (usually with even more letters and numbers after that depending on your region), but for this review we'll be shortening it to the S28 model. Samsung also advertises it as the "Odyssey G70A 28-inch" or the "Odyssey G7 UHD 28-inch" in various countries. Viewing angles are good as expected from an IPS panel, and the fact that it's flat versus the original G7 makes it much easier to view at off angles. Uniformity was very solid as well, only a few small deviations across the entire panel, not enough to really be noticeable in practice. This is great from a 4K monitor that you might want to use for a bit of productivity work. HDR Performance As we move down the refresh rate range, as gamers playing with variable refresh enabled might do, response performance is consistent. The response time average only increases from 4.90 to 5.08ms at 60Hz which is a very small difference. However, overshoot does increase, and there are no real signs of variable overdrive being used here. There is a good argument that anything over 144Hz is excessive given how little different you'll see in the jump between 144-240Hz, but with the latest graphics cards from Nvidia and AMD powering gaming PCs you can expect many low-demand titles easily smashing past 144fps. Whether you'd actually notice the difference is an open question, but you'll have the peace of mind knowing that if you're hitting up to 240fps in your favorite game then your monitor is keeping up.

Fantastic performance and unbeatable design

At 144Hz, the G7 S28 performs pretty well. The response time average registers in under 5ms, and the level of overshoot is minimal for the majority of transitions. This leads to a really solid cumulative deviation average of under 500, right where I like to see modern IPS displays. Refresh compliance of over 90% is excellent, too, suggesting this panel is comfortably capable of refreshing at 144Hz.
