This one I’m using is what I’d recommend, AW3425DW 2nd best 34” at an understandable price. If you want the latest but the greatest, which is way overly expensive for a monitor go for the PG34WCDN.

it's not a review but a sponsored ad. not a single downside is reported. this panel is still suffering from QD-OLED dimming behavior - in peak 1300 mode it will be dim in high APL scenes and in True Black 500 mode it will top at 500 nits. EOTF boost is present but is a compromise (see TFT central review for that). the black levels in bright room are still much inferior to the WOLEDs (see Monitors Unboxed review). VRR flickering is still not solved and Anti Flicker features are still a crutches that will turn off parts of the VRR range completely it is a great monitor and I will probably buy it, but not without downsides. this review is of low value

The new 34” mentioned in video seems like same as the MSI, ASUS & Gigabyte monitors down to the protective film, curve, new pixel design, etc. The only thing that is very odd is all of those are 360hz, but this one is 280hz, assuming they are the same panels from Samsung, I wonder why they downgraded that part given the display probably supports running 360hz. 🤔 I have the Asus 34in 360hz with my 5090 and it runs great, the film is kinda a cross between glossy and matte (at least in my opinion). The price for the 39in 5K2K is insane if that’s what it turns out to be, wonder if they will also out-price the other new 34” that came out this year.

I´m running the PG34WCDN (coming from a LG42 C2) and I´m really liking it. Of course the other display type needs some time to adjust to but after 2-3 days I was all in. A really good Monitor.

Would be nice to have. But I'd rather have my frames for unoptimized games being pushed to the max instead of struggling because the new hot resolution moved in to town . The Asus 360 Hz 34 inch is my go to for now.

I'm getting the Asus model regardless of price. I have been using the XG34WCDG and I absolutely love it. I still have some time before my return period is up but will be taking advantage of that and getting the PG34WCDN as soon as I'm able to.

I really did not like the 3425DW despite loving the 3423DWF. Maybe I got a faulty unit but I found its brightness and HDR capabilities lacking in comparison to its predecessor. That said, if you’re getting a monitor now, I would HIGHLY encourage you wait a few months for the new Gen 5 QD OLEDs if you want a 34” 3440x1440p or wait a little longer for the 39” WOLED 5K2K from LG. Personally, I’ll be picking up the Asu PG34WCDN as I love the current asu ultrawide QD OLED panel I have and this one just cranks it up across the board (newer panel leading to better brightness and colors, blackshield film providing extra hardness of the coating, DP 2.1, 360hz). I am curious to see what the LG 39” 5K2K will be like but I just couldn’t get myself to like their 2025 model because I hated the matte coating and this is looking to also be matte, albeit a higher quality version from the previews.

Yeah it looks for movement. So if you’re still it’ll think you’re not around and turns off. You gotta wave your hand or something every so often. I’ve turned it off on mine because it got really annoying for the screen to go black in the middle of gaming.

I'm testing that out right now actually. I picked up the PG34WCDN last week after using the PG27UCDM. The drop in ppi and resolution sharpness is very noticeable in some content, not so much in others. I'm currently running them side by side and honestly, I think I will be returning the UW. The form after is great for work with the extra real estate. But I mostly use my setup for gaming on content consumption which I find better on a 4K display. I preordered the LG 39GX950B which should be coming in sometime next week so we'll see how that holds up being a 2160p UW screen. I am worried about the matte coating on it though so we'll see how that fares.

I just got my PG34WCDN. While, it is good, coming from a 27” 4K screen I can really feel the drop in resolution on some places. I have the 39 LG on preorder so we’ll see how that fairs.
