    • Stunning picture quality and the best gaming monitor I’ve owned.
Size: 34" 175Hz AGON PRO
The AG346UCD is on another level. The colors pop, the blacks are truly black, and the motion clarity is unreal. Everything looks crisp and fluid, and the QD‑OLED panel makes SDR and HDR both look fantastic. I’ve owned a lot of monitors over the years, and this one instantly became my favorite. It’s bright, fast, and incredibly immersive. If you’re on the fence, just get it — you won’t regret it. ... show more

    • An amazing monitor, once you go oled you can never go back!
Size: 34" 175Hz AGON PRO
It arrived in it's original packaging so basically exposed which is why I'm glad I was watching for it because who knows what could have happened to it unattended but regardless holy cow this is amazing! The screen picture quality is beautiful and the refresh rate even though it's not high like 240 it still is 175 Hz and it feels smooth as butter that it actually makes scenes feel so cinematic. The text also happened to be clear too which is surprising because I heard that oleds make text look blurry but I can fortunately report that is not the case as a matter of fact it seems enhanced. It does include built in speakers but I haven't tested those since I have my own external speaker system. The RGB on the back of the monitor isn't necessary but it is a nice touch I guess. If you haven't already I do recommend you buy this hidden gem because it's worth every penny. ... show more

    • Screen Protector Is the Only Complaint So Far Screen Protector Is the Only Complaint So Far
Size: 34" 175Hz AGON PRO
Review Image by Devin
The monitor is great. OLED is beautiful. The color is a little warm compared to my other monitors but overall it's great. Only complaint is the screen protector they had on it was very difficult to remove. The yellow tab that you're supposed to pull to remove the protector came off without the protector even budging, so it took me some time to realize there was a protector at all. Then when I went to remove it, it had been pinched between the screen and the plastic along the bottom, so much have been installed before the plastic bottom was. Peeling it left some residue that I can't remove, so it looks not great, kind of like it's dusty but you can't just clean it cause it's sticky and pinched between the plastic and screen. ... show more

    • SO happy with this monitor
Size: 34" 175Hz AGON PRO
This monitor is insane! The difference of OLED is absolutely breathtaking. If you are looking for something to upgrade, this monitor will make it feel like you bought a whole new rig. Especially if you had a LCD panel.

    • Incredible GLOSSY Coating QD-OLED Ultrawide Monitor with (HDR 1000 MAX) Mode Incredible GLOSSY Coating QD-OLED Ultrawide Monitor with (HDR 1000 MAX) Mode

Beautiful QD-OLED GLOSSY Coating 34" Ultrawide Curved Monitor for gaming and productivity with "HDR 1000 MAX" mode from the brand that brought you the legendary Q27G3XMN Mini LED that was praised endlessly by Monitor Unboxed and Rtings for the best local dimming firmware and algorithm in the industry. Pros: + 4 Year Warranty + GLOSSY OLED Panel, no nasty matte coating to be found here looking at you LG and BOE + Incredible Quantom Dot Colors it gives OLED an even wider brighter color gamut + Sturdy stand very heavy stand base. + Features a "HDR 1000 MAX" mode this is only OLED monitor I have found with this feature. + The best OLED Care features all customizable so it won't annoy you with reminders. + They don't advertise it but the inside of the monitor has a huge heat sink to cool the OLED panel + Ventilation is superb, interior design of the monitor is a work of art, absolutely clean wiring etc + Price is the lowest I seen only $600 for a ultrawide 34" QD-OLED from a reputable brand. + Ultra Wide looks incredible no need to crop black bars out of movies in VLC media anymore + It's OLED so response time is instant it destroys any E-Sport TN LCD in speed, Color and Contrast. + Ultrawide curve is incredibly natural to the human eye there is no going back + Awesome glossy reflection handling perfectly visible in daylight the curve eliminates most reflection. + Incredible Menu OSD with joystick navigation + Has built in old school power supply that lasts forever, no stupid external adapters like other monitor The reason external power adapters suck is because they fail due to no ventilation and cramp design. Cons: - Once you go Ultrawide you will be so spoiled you can never go back to 16:9 Ratio again - Stand is V shape so your mouse can run into it if you sit super close to the screen - Do NOT enable "Logo Detection OLED Care" enable everything else except this, for some reason it makes your OSD disappear quick could be a bug not sure cause AOC firmware is top notch - Menu Joystick is a weird triangle shape I wish it was a hollow circle like Gigabyte monitors. No big deal I use twinkle tray app to control my monitor brightness via Windows task bar anyways - AOC doesn't sell this or any OLED Monitor in Trinidad and Tobago so I had to buy this on Amazon and ship it to Trinidad in the Caribbean so I have no warranty in my country if something goes wrong. ... show more

    • Great OLED Picture Quality, But Doesn’t Fully Utilize High-End GPUs
Size: 34" 175Hz AGON PRO
The monitor is decent, but it doesn’t fully live up to expectations when paired with high-end hardware. The picture quality and OLED contrast are good, and the ultrawide format is great for immersion, but the overall performance doesn’t feel like it keeps up with a top-tier GPU. Running this with an RTX 5080 Master Ice, it often feels like the display becomes the limiting factor rather than the graphics card. The panel responsiveness and processing inside the monitor don’t seem fast enough to fully take advantage of the performance modern GPUs can push. In fast-paced games especially, it feels slightly behind what you’d expect from a premium display. It’s not a bad monitor by any means, and it will still be a big upgrade for many setups. However, if you’re pairing it with very high-end hardware like a 5080-class GPU, there are faster and more optimized panels on the market that will better match that level of performance. Overall: good visuals and immersion, but not the best choice if you’re trying to fully utilize the power of a flagship GPU ... show more
