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

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.

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.

I actually have tried both formats you’ve considered and the 34” 3440x1440 format as well with a 5090. I have the 540 Hz PG27AQWP-W, the 4K 240 Hz PG32UCDM and the 165 Hz Alienware 3432DWF and I can share a few thoughts after using them all. The 540 Hz display is incredible for competitive shooters, bar none. I did not expect there would be any meaningful difference switching from 4K 240, but it was immediately clear how crystal crisp the 540 Hz is in Valorant to me personally. When flicking and panning on the 4K 240 there is a bit of blurriness that is just not there on the 540 Hz panel. It handles motion by far the best out of any monitor I’ve used and although it didn’t really make me a better player by any means, it certainly was an upgrade in gaming experience for this type of game. The 4K 32” 240 Hz format is the best all arounder, but as others have pointed out even on a 5090 I find it a struggle at times. The overall image quality is of course sharper and text is sharper, but in terms of black levels and colours I genuinely find the PG27AQWP-W superior because of the TrueBlack Glossy coating. It does indeed boost perceived black levels for me and it’s very obvious in games like Dead Space. The PG32UCDM3 would be a strong contender here with its BlackShield coating. My Alienware is only 165 Hz given it’s a first generation OLED, but even for that the immersion and general use experience on desktop is the best with its ultrawide format. The colours, refresh rate and all that are noticeably worse than both of my other newer OLEDs, but playing in 21:9 is truly a treat and working on it is amazing compared to 16:9. Like a few others have pointed out, and based on what’s available today/upcoming, and your varied usage scenario the PG34WCDN I believe will be your best bet, followed by the PG32UCDM3 and then the PG27AQWP-W. The new ultrawide has RGB Stripe for great text clarity, 21:9 native but supports aspect ratio control to 16:9 for competitive games, has 360 Hz which is plenty, BlackShield coating which boosts perceived black levels and helps with the tinting issue of QD-OLEDs and no DSC, basically checking every single box you could ask for while also being incredible for productivity with its improved subpixel layout and ultrawide format. The PG32UCDM3 would be a good option as well, 4K really is darn crisp and not having to deal with black bars in some games with 21:9 is nice. Since you don’t exclusively play competitive games, I placed the PG27AQWP-W last in your case because that monitor really was made for competitive shooters. While it is excellent in other games as well, I still put story-rich games on my 4K monitor over it and if I have to do some work, I work on the 4K panel or ultrawide. Its only win is in Valorant/CS2/OW and the such but doesn’t really win over the other formats otherwise. If you really do want every last bit of advantage possible though in your Overwatch games, then yeah the PG27AQWP-W is the current ultimate 27” 1440p display for that purpose alone.

This is a review of the 5th Gen QD-OLED panel as featured on the new [ASUS ROG Swift PG32WCDN](https://tftcentral.co.uk/news/asus-rog-swift-pg34wcdn-unveiled-with-34-360hz-5th-gen-qd-oled-panel) and [MSI MPG 341CQR X36](https://tftcentral.co.uk/news/msi-announce-the-mpg-341cqr-x36-with-34-ultrawide-360hz-5th-gen-qd-oled-panel). Here's the summary from the video along with some extra info from [TFTCentral](https://www.youtube.com/watch?v=s2nHKDMYifg) [reviews](https://www.youtube.com/watch?v=UAOMAExqX6o) and [HDTVTest new video](https://www.youtube.com/watch?v=tN9P2TaU0vg): - The 2026 QD-OLED panels used on the ultrawide monitors now feature the V-Stripe ([a.k.a. "True RGB"](https://tftcentral.co.uk/news/samsung-display-announce-mass-production-of-new-34-qd-oled-panel-with-v-stripe-sub-pixel-layout)) sub-pixel layout. Text quality is "effectively identical to LCDs of the same pixel density", by far the biggest upgrade from these new panels. As described by Tim, there's no "green and pink fringing at the top and bottom of text edges" from older QD-OLED panels, and there's also no "horizontal shadowing" from W-OLED's "RWBG & RGWB pixel layouts". [The whole section on the sub-pixel layout is really worth watching](https://youtu.be/c90FLTWQiSY?si=-UfhjovdEhBqqrlW&t=140). - [The screen coating doesn't raise black levels as much as 1st and 2nd generation QD-OLED panels](https://youtu.be/c90FLTWQiSY?si=dZ3ENqLgtAPe-kOv&t=325), but the issue still persists. A 4th Gen Tandem WOLED panel with a "TrueBlack" screen coating handle black raise the best, although the coating on those panels is far glossier than the one found on QD-OLED. Tim prefered the coating of 5th QD-OLED over the "True Black" 4th Gen Tandem WOLED. EDIT: [TFTCentral found an 11% improvement on contrast levels as the screen reflects more light.](https://youtu.be/UAOMAExqX6o?si=TvJe_5JTs7hFCMyM&t=318) WOLED panels (with matte AG coating or "TrueBlack" glossy coating) still handle black raise better than their QD-OLED counterparts. - HDR brightness values with their APL (Window) values, [based on Tim's testing](https://youtu.be/c90FLTWQiSY?si=_Nqum6IIUDaYDxxO&t=732): "Around 300nits" at 100%, "Around 520nits" at 10%, "Around 1300nits" at 2%. SDR brightness can go up to 307 nits. - 5th-Gen QD-OLED 3440x1440 panels now feature a 360Hz refresh rate. Tim highlighted the better compatibility with 4x DLSS Multi Frame Generation than with an older 175Hz panel. - Samsung Display's aggresive ABL is still present on these new panels, but both ASUS and MSI have added some hacks (a.k.a. an "EOTF boost" mode) in their OSDs to try to work around the aggresive ABL. Monitors Unboxed will touch on this in the future, but [HDTVTest already has a more in depth explanation on how this "EOTF boost" was implemented on the MSI monitor's OSD (the rest of his video is also pretty good and highlights a few bugs on MSI's HDR implementation)](https://youtu.be/tN9P2TaU0vg?si=kpLyFN5j0rB4_SCt&t=391). - From the TFTCentral articles that I shared at the beginning, both monitors share the same Semi-Glossy coating (despite the marketing name used by ASUS and MSI), an 1800R curve, improved panel hardness from 2H to 3H, VESA DisplayHDR TrueBlack 500 certification, "factory calibrated Delta<2 accuracy", 2x HDMI 2.1 ports and a USB-C Type C port with DP Alt Mode and 90W of Power Delivery. The MSI monitor features a single DisplayPort 2.1, UHBR13.5-tier port ([the monitor requires DSC to run at 360Hz, HDR at 3440x1440, as reported by HDTVTest](https://youtu.be/tN9P2TaU0vg?si=DHmZo36I5-YD0JXN&t=727)) with an MSRP of $1,099. The ASUS features a single DisplayPort 2.1, UHBR20-tier port with no announced MSRP. - HDTVTest also teased the announcement of an "even higher tier QD-OLED monitor" from MSI right at the end of his video. I wonder if we're getting a new 4K or even a 5K2K monitor to compete with LG's most recent monitors! EDIT: [MSI announced a new QD-OLED monitor in their MEG series](https://tftcentral.co.uk/news/msi-introduces-the-meg-x-34-qd-oled-monitor-with-built-in-a-i-features). The panel is the same but this one it's an "AI" monitor... Overall, I'm really glad that text fringing seems to be solved on both 5th Gen QD-OLED and [4th Gen Tandem WOLED RGB-Stripe monitors](https://tftcentral.co.uk/news/lg-display-announce-a-new-27-4k-oled-panel-with-rgb-stripe-layout). However, unlike the RGB-Stripe Tandem WOLED which have brightness levels comparable to 1st Gen QD-OLED (1000nits@2% APL, 500nits@10% APL, 250nits@100% APL), 5th Gen QD-OLED will be far brighter while having a (mostly) similar text quality, from the info that we have so far. For those interested on more monitor reviews that are not from the usual sources (Monitors Unboxed, TFT Central, HDTVTest), you can wait for a future review from chinese reviewer [小雪人评测](https://www.youtube.com/@%E5%B0%8F%E9%9B%AA%E4%BA%BA%E8%AF%84%E6%B5%8B/videos) to check how text-fringing shows up on more complex chinese characters as well as Stroboscopic Visibility Measure (SVM) testing and a teardown of the monitors.

Yeah, I get what you're saying. It's not that all movies and TV Series are graded to the limited dynamic range of a projector, it's just that some of the most hardcore and/or avant-garde movie directors tend to favor the more limited dynamic range of a projector that is used on a movie theater or in an enthusiast grade home theater setup over the far wider dynamic range that it's present on most consumer displays (including tablets and smartphones). For comparison, having so many mobile devices of many different price ranges come equipped with an OLED screen these days and having phones like the iPhone record in HDR by default really helps to push the adoption of the format in other mediums such as social media content. And even then, not all social media handles HDR video the same way, with stuff like YouTube taking an entire week to process a HDR video lol.

I actually have both monitors too and currently trying to figure out what I want to keep. The 39GX950B is growing on me, but I won’t lie the matte is a bit frowny face. The PG34WCDN is a nice panel, but it doesn’t feel like an upgrade. I have a PG32UCDM and the PG27UCDM. So part of me is just going to return the PG34WCDN because the PPI downgrade is MASSIVE to me. The panel is good and clear, but 1440p is 1440p. I drive this a 9950x3d and 5090 so resolution isn’t too much of a concern. Also, another thing to note is there is a difference in terms of color accuracy. The LG, no matter how you tune it will not be accurate. ASUS has this down without question. Literally the reason why I have the monitor still. The lifted blacks in HDR with the LG may seem like a good thing to some, but it is not great for experience in my opinion. I guess when it comes to this, you either go with the LG (over EOTF curve tracking) or ASUS (under EOTF curve tracking unless using TB500)
