The AGON PRO AG346UCD is an incredibly high-performing QD OLED curved display that boasts fast refresh rates and quick response times. The top spec attracts a high price, though, and if you want something similar for less money, then I'd recommend the Philips Evnia 34M2C5501A as an alternative.

The AGON PRO AG346UCD joins a growing list of curved monitors designed to provide immersive gaming experiences. It's remarkably similar to the Philips Evnia 34M2C8600, which we reviewed at the back end of 2023. This is unsurprising though, considering AGON and Philips are owned by the same parent company.
More recently, I had the pleasure of reviewing the Philips Evnia 34M2C5501A and wrote the following: "It's big, classy, and curved; this latest Evnia monitor is another smash from Philips." These types of curved monitors are not for everyone but what they lack in popularity they make up in performance.
The AG346UCD is a QD OLED, or Quantum Dot OLED, a technology that combines the best of OLED and Quantum Dot technologies. It has the benefits of providing peak brightness levels without losing contrast, as well as generally more vibrant colours.
The monitor itself was incredibly easy to set up and as soon as it was hooked up to my laptop, I began my testing. Read on to see what I thought of it and whether it's likely to make it into our list of the best monitors.

The two things you'll notice when you unbox the AG346UCD are first of all that it's ultrawide and second, that it's curved. If you're not a fan of either of these qualities in a monitor, then you're best off opting for something like the Philips Evnia 27M2N8500.
The 1800R curvature does a fantastic job of replicating the eye’s natural visual field, resulting in a perfect level of immersion. Don't get me wrong, this is no ultimate surround visual and sound experience but it is as good as it gets when we're talking about 34-inch monitors.
The aspect ratio is 21:9, which won't suit all games but if you're also using the display for productivity workflows, then you'll be more than happy. Placing application windows side-by-side is also easier with the extra width. It might even save you from needing to buy two monitors.
The resolution of 3440 x 1440 pixels means you won't see it in our guide to the best 4K monitors but at WQHD it's not far off. It certainly provides enough detail for almost all the most-demanding games around at the moment.
The monitor includes a range of ports, including HDMI, DisplayPort, and USB-A, as well as a headphone-out. These are conveniently located at the rear of the monitor, with all but two of the USB-A ports facing downwards.
Unfortunately, you won't find anything like the AI-enhanced Ambiglow that can be found on the Philips Evnia 27M2N8500. This feature "analyses the incoming image content and continuously adapts the colour and brightness of the emitted light to match the image." Maybe it's not a game changer but it's certainly nice to have.
I think AGON has nailed the design of the AG346UCD. It's beautifully designed and well-constructed with premium materials. Three sides of the display are frameless, which helps keep the focus on the game action or whatever you're working on.
Features and performance

The AG346UCD features some pretty impressive specs, including a max refresh rate of 175 Hz and a response time GtG of 0.03 ms but does it perform in reality? Absolutely. As you'd expect, I had no problems with lag, motion blur or ghosting effects but instead thoroughly enjoyed using the monitor.
It's worth noting that the highest refresh rate of 175 Hz can only be achieved using the DisplayPort compared to 100 Hz through the HDMI port. You will want to consider this before making any purchase.
The QD OLED display outperforms most OLED and LED monitors I've had the privilege of using. The colours are vibrant and there's no problem with the contrast. VESA-certified DisplayHDR True Black 400 meant that the full range from blacks to whites was beautifully displayed.
I was a little disappointed by the 250 nits of brightness. I would have expected nearer to 400 nits for this price. The higher level would have made the monitor much more usable in bright environments.
If you're keen on a curved gaming monitor with the latest QD OLED technology, then the AG346UCD is well worth consideration.
Price
(Image credit: Future)
The AGON PRO AG346UCD is currently available at an MSRP of £669.99 / $649.99. This isn't the most affordable monitor but you do get what you pay for. The QD OLED technology and almost 4K resolution make it one of the best gaming monitors around at the moment.
If you like the idea of a curved monitor but are not happy about spending so much money, then you could opt for the Philips Evnia 34M2C5501A monitor, which is priced at £299.99. There are also 27-inch (27M2C5501) and 32-inch (32M2C5501).

AGON PRO AG346UCD review: an immersive ultrawide QD-OLED display
