  –  It’s 49 inches of the highest resolution this form factor comes in. It’s 240 freaking Hertz, and it’s DisplayHDR 1000 certified. I mean on paper, this is the new God of gaming monitors. If it can overcome the shortfalls of it’s VA panel lineage. And we’re gonna find out today in our unsponsored full review, which isn’t to say we don’thave a sponsor at all, it’s just not Samsung. ORIGIN PC has got powerful,high end desktops and laptops with a multitude of options, including up to twoterabytes of fast storage with Samsung’s 870 QVO SSDs. Check them out today at thelink in the video description. (upbeat music) The big concern with VApanels, like in the G9, has to do with pixel response times.

That’s how long it takes a pixel to go from one value to another value. Like the blue pixels of mydesktop background here, turning white as I movea window across them. Gaming monitors, including our G9 here, often advertise a greatergray switching time of about one millisecond. But these are marketing numbers that never tell the whole story, in part, because they are averages. In the real world, pixelresponse times vary depending on the valuethe pixel is starting at, and the value it’s driving toward. Looking at measurements from the first 240 Hertz VA monitor ever, the Samsung C27RG50, we can see that the slowest transitions occur when going from the lowest values. So, the deep blacks thatVA panels are known for up through other dark and medium grays. Now, there is a way toget faster response times, just send more voltage to the pixels, but as with most good things,you can have too much. 

Pixel over drive comes with a trade off where you can overshoot the target value introducing Inverse Ghosting Coronas, that I personally think look way worse than regular smearing. So the question for the G9, and I guess also the G7 by extension, because it’s similar but justin a 16 by nine form factor, is whether Samsung has been able to find that overdrive Goldilocks zone. To find out, we set up a pursuit camera to photograph response timeartifacts without capturing the human brain imposedmotion blur that you see when looking at movingobjects on a screen. This is at 240 Hertzwith Adaptive-Sync on. The blacks are smeared more when the ship is againsta dark background, but overall there’s very little smearing compared to the pursuit camera pics that TFT Central took ontheir review of the C27RG50. Instead, we see Coronas onthe backside of the ship as well as a colorinversion of yellow to blue caused by overshoot. And this is what you’re gonna get if you plan on gamingwith G-Sync, or FreeSync, or Adaptive-Sync, or variablerefresh rate turned on. 

However, with variable refresh rate off, you can actually adjust the overdrive setting through three steps, with standard introducing fewer Coronas, though, you still cannotice them in games. If it bothers you toomuch, you could in theory, turn the refresh rate downto 120 or even 60 Hertz at the expense of clarity,but in our testing, it really didn’t seem to help much. Now, as someone whoisn’t terribly bothered by VA black smearing in general, and in light of these test results, I stand by what I saidin that sponsored video. This monitor delivers an absolutely incrediblehigh refresh rate, immersive gaming experience. But, don’t click away yet because there are some thingsthat you should know about it. You may recall that ourprevious God of monitors, the Asus PG27UQ, was capableof 4K HDR gaming at 144 Hertz, but only with 422 Chromo Subsampling, which introduces colorfringing on fine details and can make text harder to read. 

That was because of thebandwidth limitations of display port 1.4. But this monitor alsouses display port 1.4, and it’s refreshing at an eyepeeling 240 times per second. Yet you get full RGB, 10 bit color. How is this even possible? Is it because 5120 by 1440is fewer pixels than 4k? Well, that does help, but the main reason is actually that this monitor’s display port 1.4 port supports a feature called DSC. DSC, or Display Stream Compression is only supported on20-series and video cards and AMD cards from 2019 onward. Without it you’re actuallystuck with eight bit color at 120 Hertz, and ourswouldn’t even overclock to 144. By the way, hooking up twocables, that won’t help. With DSC, though, you can unlock the Odyssey’s fullpotential, and to our eye, even though it is being compressed, there’s no visual fidelity loss, just way more efficient useof the available bandwidth. Speaking of visuals, they’re fantastic. lttstore.com, by the way. The G9 uses a quantum dot enhancement film to achieve near professionallevels of color accuracy and has 73% coverage ofthe rec 2020 color gamut. The screen is also quite uniform. And of course, the 1,000nit peak brightness makes your HDR moviesand games really pop. One thing I will say is that if you’re watching a movie, I would recommend doing that alone because she ain’t builtfor great viewing angles. She is built for immersion though with apparently theworld’s first 1,000R curve, which is tighter thananything we’ve seen before. 1,000R is said to be similar to the curvature of the human eye, increasing the proportion of the screen that you can see withoutstrain, and decreasing fatigue. And there are actually some studies that seem to back this up.

 I do have one fairly big problemwith this monitor though, the noticeable flickering when HDR is on. Now, it’s more obvious on the desktop than when you’re actuallywatching or playing content. But I was able to tellwhile playing CS:GO, and I don’t know if this is related, but there was some talk ofthis monitor being recalled, though now Korea tells us that they’re just doingadditional testing, not recalling it. So, whatever’s going on, I hope that it’s related to the flicker because somebody’s got to address it. Leaving only then the final question, should you buy this monitor? It’s definitely notthe highest performance 240 Hertz gaming display onthe market, but what it is, is one of the most completepackages out there. Sure, it only has 10 local dimming zones, which sometimes looks bad.
