Why you can trust Tom's Hardware Our expert reviewers spend hours testing and comparing products and services so you can choose the best for you. Find out more about how we test.

The Odyssey G7 defaults to its Custom picture mode, and that’s where it should stay for best results. Though all calibration controls are available, there is no need or benefit to adjustment. It has one of the most accurate default images we’ve come across.

Grayscale and Gamma Tracking

We describe our grayscale and gamma tests in detail here.

Only a few professional monitors can match the accuracy of our review focus. It’s one of the best we’ve measured. Grayscale errors are completely invisible with only 10 and 20% reading higher than 1 Delta E (dE). Gamma is also visually perfect. The tiny aberration at 90% represents only 2 nits, which is almost nothing.

If you prefer the smaller sRGB color gamut for SDR gaming and video, Samsung provides a usable mode that includes near-perfect grayscale and gamma tracking. Its red is a little over-saturated, as you’ll see in the next section, but it is still very functional.


Though we were able to adjust the C32G75T’s Custom picture mode, we could not make the grayscale tracking any better. By default, it’s as close to perfect as we’ve seen. The sRGB mode’s 0.82dE value is also impressive. Gamma deviates from 2.2 by only 1.36% with a tight 0.05 range of values. It doesn’t get much better than this.

Color Gamut Accuracy

For details on our color gamut testing and volume calculations, click here.

Measuring the Odyssey G7 against the P3 spec shows a little under-saturation of the green primary, but all other targets are spot-on. The average error of 1.45dE is extremely low for any monitor and especially impressive for a gaming display.

The sRGB mode is also nearly error-free, but the red primary is visibly over-saturated. You’ll notice slightly ruddier flesh tones and more brilliant sun and fire textures. There is a slight magenta hue error as well.


0.93dE represents the C32G75T’s native P3 color gamut. Our sRGB average error was just 1.80dE. You can see that Samsung takes accuracy seriously because our review subject was bested only by the Samsung 27” CRG5. Of course, all the monitors here put up impressive color numbers with accurate and vivid saturation of all hues.

We’ve tested a few monitors that surpass 90% coverage of P3, but our review focus covered a little more than the competition. The bottom three screens in our Color Gamut Volume chart above are sRGB-native screens, so their results are appropriate. In the Odyssey G7’s case, you’ll want to use a software profile when working with color-critical apps in the sRGB or P3 gamuts.

    Those are all premium specs, but I wonder how many will benefit of that leap to justify more than double the price of the Gigabyte G32QC

    At least make two models , Flat and Curved of PC Monitors Samsung . you already do that for TVs

    HDMI 2.0 is not very Xtreme.

    Nope! too much for a 2560x1440 Monitor, I don't care how good it is. Maybe 2 years ago, but not today.
    4k gaming is on stage now and you can get a decent 4k monitor for ~ the same price. If I am spending $700 on a new gpu from Nvidia or AMD, I ain't wasting it on this.

    If it was ~$500, maybe. the Benq EX3203R is 144 Hz, very nice and is on par with this. It is $599 currently on Amazon.

    What is the cord length of power brick to monitor? On my Nixeus it's too short too reach the floor, so the brick and all the cord they did give me are on the desktop! Idiotic and I don't want that again. A detail rarely mentioned in reviews.

    Hello Christian Eberle, and thanks for doing a review of this interesting monitor model from Samsung! :)

    As I'm personally interested in static contrast fluctuations on the VA panel used in this particular model and would like to compare results between diff. monitor reviewers using display sensors in their reviews. Could you perhaps be asked to be so kind, and provide a new contrast reading, but this time done using the "industri standard" luminance of 120 nits......instead of the 200 nits used as reference in the review? Pretty please.....would make it so much easier to compare measurements results! ;-)

    As I'm new to reading monitor reviews on TomsHardware, I don't know how "neerdy" you guys are......but this model from Samsung also has some raised concearns from other users, about image flickering when having VRR functionality activated(freesync and G-sync). And since you didn't mention this in the review, it could also be usefull to know, what firmware version your review monitor was using? :) But if you were not aware of this issue at all and perhaps was "Lucky" to get a sample with less visible flickering, you may not have paid enough attention to this issue, to be able to discover this during the time doing the review.....but purely speculation on my part! :)

    You can read about the VRR flickering issue, from other PC monitor review sites, like forexample TFTCentral (Link = Scroll down a little undtill you see the grey text message box titled "VRR FLickering issues?" ). But if this indeed is fixed on your review sample, this would be a good thing......and interesting to know, if it has anything to do with the firmware version used by the monitor! ;-)

    Otherwise great review Christian, I like monitor reviews that include actual measurements, and not just the "other ones" that relies solely on subjective observations by the reviewer! :)

    There's talk of a possible class-action lawsuit regarding the flickering these monitors suffer from while using G-Sync, and this article not only fails to mention that but goes so far as to call its G-Sync performance "flawless". Why is that? Could you clarify the build date by listing the number following the letter 'n' in your particular model? Is it possible that the issue reported by ~99% of Odyssey G7 owners has been rectified by Samsung?

    Uhh, the same? 144Hz vs 240Hz?? And since Samsung is "fameus" for making market leading VA panels......I sincerly doubt that particular BenQ monitor features a VA panel that can keep up with this latest VA panel from Samsung, that currently wears "the crown", when it comes to pixel respons times in monitors of this size. So in other would get a lot more trailing/black smearing on that BenQ monitor........this, together with g-sync. support, is what you pay extra for in the Samsung monitor! And yes, you of course also automatically get less fps in graphics heavy sceenes in a future video game, because of the 4k resolution! And your gaming rig is thus less "future proof", in regards to be able to keep on cranking the gfx settings to the max in games and still enjoy playable frame rates in the future! Now! Don't know if I accidentally made myself look a bit stupid, trying to "cut out" my points! But hope my points was clear! :p

    Personally, I feel the curve is too aggressive. Moreover, I feel the price is fairly high. Not sure if it is worth the perfect 5 stars.

    When will 32" Curved 4K GSYNC certified Gaming Monitor (>120Hz) reviewed here ?
    My old LG 32" 4K Monitor is no curved and only capable of 60Hz. I'm looking forward to upgrade it ;)
