AOC AG352UCG Curved G-Sync Gaming Monitor Review

Early Verdict

A curved ultra-wide gaming monitor is going to be expensive no matter what, but the AOC AG352UCG manages to undercut the competition by a little. No corners have been cut however as this display delivers solid gaming performance courtesy of G-Sync and a 100Hz refresh rate. Color accuracy is quite good, and after an easy change to the color temp, everything lines up right to spec. If you’ve been waiting for an opportunity to add one of these screens to your system, the price/performance ratio has never been more attractive.

To be classified as a gaming monitor, a display must meet two minimum criteria: adaptive sync and a high refresh rate. These days, G-Sync or FreeSync is a must for anyone who cares about motion quality. Putting the video card in the driver’s seat means the panel only draws a frame when ordered to. It isn’t locked into a fixed refresh cycle. So then the choice comes down to Nvidia or AMD.

It seems that most premium screens choose G-Sync, with its more consistent low framerate support. If you can’t support high speeds with your current video card, it’s nice to know there won’t be tearing when the action drops below 40 FPS. To get that consistency with FreeSync, you have to check the specs carefully, because not all monitors work the same. On the other hand, G-Sync also adds a $200 tariff to the price of entry compared to FreeSync generally speaking.

Today, we’re checking out the AG352UCG, an ultra-wide member of AOC’s Agon gaming display line. It sports an 1800mm curve radius with a high-contrast AMVA panel running at 3440x1440 pixels. G-Sync is there too over a range of 24-100Hz. It’s all wrapped in a stylish chassis with colorful LED effects and a solid-aluminum stand. Let’s take a look.


Once you’ve satisfied with the refresh rate equation, the choices in gaming displays are vast. Ultra-wide curved screens are popular for their immersive wraparound effect and greater use of the player’s peripheral vision. Many people use multiple 16:9 monitors to achieve the same thing, but now you can have a more seamless, single-screen experience. The AG352UCG’s 1800mm radius curve is about as tight as it gets. And a generous 35” size means you won’t have to sit super close to lose yourself in the game world.

Users who place resolution high on the priority list will be attracted to the Agon’s 3440x1440 specification. That means a pixel density of 106ppi, which is close to a 27” QHD monitor’s 109. We’ve long considered that good balance between clarity and speed. Speaking of the latter, 100Hz is the max refresh here, which may look a little weak next to the latest 240Hz screamers coming from Asus, Acer, and AOC. But the AG352UCG has something else to recommend it: an AMVA panel. It offers double the contrast of the best IPS or TN screens, and that’s something anyone can readily see. It might just be worth a little framerate sacrifice.

Packaging, Physical Layout & Accessories

The AG352UCG is a substantial display and it comes in a carton to match. The panel, upright, and base are separately packed and well protected by large foam blocks. Assembly requires the use of a Phillips-head screwdriver to attach the upright, while the base bolts on without tools.

Bundled cables include DisplayPort, HDMI, and analog audio. The latter is intended to complete a mic interface between the monitor and your PC. Although there is a built-in USB 3.0 hub, no cable is included. To use it, you’ll need a cable with a micro-B plug, which is somewhat unusual. The power supply is external like most ultra-wide displays, and occupies a large brick. Documentation and drivers can be downloaded from AOC’s website.

Product 360

AOC typically puts a lot of effort into its product’s styling, but the Agon line is a cut above the norm. The AG352UCG has generous amounts of silver trim and a unique LED array that not only lights up the panel’s bottom edge but adds four large accents across the back. You can choose a red, green, or blue effect in the OSD. We only wish the color would change to indicate G-Sync operation like with some other displays.

The anti-glare layer is 3H hardness like most others but has a little more shine than is typical. This increases the clarity factor noticeably, but you’ll need to take a bit more care when setting it up to avoid reflections. Luckily, curved screens are easier to deal with in this regard. The bezel is finished in a gloss black and is relatively wide with a 15mm top and sides, and 25mm at the bottom. Underneath is the aforementioned LED bar, which emits a soft glow, almost like a bias light.

The stand is one of the most substantial we’ve seen. It’s made from solid aluminum finished in a premium satin sheen. Both the base and upright are made from the same material, and the latter is capped by a useful handle. Movements are solid and sure, as good as any premium monitor we’ve laid our hands on. In addition to a 4.3” height adjustment, there’s 30° swivel in each direction and 29° back tilt with 5.5° forward. A small hook flips out from behind the upper-right to hang a pair of headphones. The stand can be removed if you wish to use the 100mm VESA mount holes.

Video inputs include one each of HDMI 1.4 and DisplayPort 1.2. The former can be used at the monitor’s native resolution up to 60Hz. For G-Sync and 100Hz, DisplayPort is the only choice. You also get one upstream and two downstream USB 3.0 ports along with headphone, mic in, and mic out. Two small speakers can be seen behind the up-facing grill, just above the large silver trim piece on back. They play louder than you might expect, but there is some distortion at higher volumes.

    Thanks for the review.

    Not in the market for an monitor but if I was I'd probably get this one. Good size, resolution, and the 100hz is actually a reasonable mark for people with single gpu solutions. At ultra many games can pull down even a 1080ti into the 60-100fps range at a resolution like this.

    Sounds like this monitor is deserving of an award but it's definitely not there. I suspect that it will pop up in a few hours after a ninja edit.

    I think the issue this monitor faces is quite simple. The price premium on a gsync monitor. I looked at them recently and there is a $200 markup over the FreeSync version. It's just really hard to suggest these monitors when a person is on a $2000 budget for the whole machine when that difference is an entire graphics card tier.

    As of 11/6/17, Microcenter has this monitor for $799. Fantastic deal for a 35" curved ultrawide 1440p.

    This monitor will probably be my christmas present!

    still waiting for the next version of the Samsung CHG90 with DP 1.4; If they can get it to 7680x1440@100hz /w gsync then i would buy that and replace my 3 monitor setup i have right now.

    It still baffles me that these things are so expensive, there have been monitors at this resolution/frame rate for a few years now and still we are seeing 800 price points. I obviously don't know anything about the difficulty of manufacturing these things but it sure surprises me that price has remained this high for this long. Monitors seem to be one of those things that just doesn't drop in price. Graphics cards get replaced so fast due to advancements in tech that if you don't want to buy a 1080ti for 700 now, wait 2-3 years and you can get the 1260ti for 200 dollars and it has the same performance.

    What a great monitor, for a new setup this is great. Sadly it is hard sell for most serious gamers to justify going back from 144Hz to 100Hz. Sure, this is a spectacular looking monitor, it is huge, resolution is decent, curved for immersion and has higher than 60Hz. But 144Hz is a bare minimum for me, and I will only seriously consider it only once it satisfies that target.
