I upgraded recently from 1440/144 27” IPS to ultra wide qd-oled 1440/175 34”. Was originally thinking 16:9 and skeptical of ultrawide, but there was a local MSI ultrawide for a good price. Definitely very happy with the purchase and can’t see myself wanting anything different for a long time. The ultrawide has been very impressive for immersion, qd-oled is stunning, and doesn’t feel excessively wide at all in games, and is also great for movies. 4 or 5 months in and I’m still impressed every time I boot something up. Comes down to personal preference probably, though probably hard to test out for long enough to get a feel for it unless you have friends with both options. Also need to make sure you have the hardware to support 35% extra pixels, but I wouldn’t change anything about my setup

That’s awesome to hear man. I was in the store and saw the 45” side by side with a (MSI) 34” QD-OLED and it really looked flat and lacking pop in comparison and wasn’t sure if it was the matte coating or the panel itself so I’m very glad to hear that the colours on this new 39” looks good (coming from a AW3423DWF myself).

I normally find a single monitor too confining to drive in cockpit so I normally use the hood view when driving. I have a rig with triple 32s so I generally don’t race on my gaming pc but I saw your question and loaded up ams2 to grab a screenshot. I feel perfectly comfortable driving on my 34” screen. It’s an msi oled 1440p unit. Do note that the extra width is a hit on the gpu, I’d say 10-15%, so make sure you’ve got the headroom. https://preview.redd.it/n6qxet3mh5pg1.jpeg?width=3440&format=pjpg&auto=webp&s=602acd76756a4131ba13934a72818c016a1ae590

No problem, as you can see, the extra width helps a lot. Which monitor did you get?

Yes, I have an AW 34" QD-OLED at home and the MSI 34" QD-OLED at work. Same panel inside both. I do both video editing and game development (coding). I used Cleartype and picked the best option and haven't had any issues with eye fatigue or reading text. I have a monitor arm for each so they're the perfect comfy distance from my face, and use dark themes and low lighting to keep the contrast in the room reasonable. I do have a side 4:3 monitor for additional code or reference web pages, especially for game dev where I may have 2-3 editor windows up in addition to the C++ code. Three years in, would not switch to anything else (I've tried a few times just out of curiosity). Maybe in 6-7 years when the next OLED tech comes out.

Hello everyone, I got my PG34WCDN yesterday and thought I provide some early impressions for those, who are on the fence to order one as well. Here are some points I oberserved in my short period of time I got this monitor. * Build quality: The build quality is absolutely excellent. No issues whatsoever. * Display: The display is absolutely gorgeous. It is noticably brighter than my previous MO34WQC2 and PG27UCDM. I thought by going from 240 Hz to 360 Hz I wouldn't notice the difference, but I did and while it isn't as going from 60 Hz to 120 Hz the response on the desktop and in games, when they reach the full 360 FPS on it you can notice it. * HDR: In HDR mode it does get so bright, that I have to squeeze my eyes when I get flashbanged, when playing in a darker room. I didn't needed to do this with my previous monitors. I am using the recommended settings from TFTCentral for SDR and HDR in their review of the PG34WCDN. * Blackshield: The new Blackshield treatment is a welcome improvement over previous QD-OLED monitors as those turned purple in a brighter room or when light hit the display. The new Blackshield solves this and I can confidently say that the PG34WCDN is just as black in a bright room as my LG OLED TV. * Text: Text looks really good. The fringing and fuzzy text is finally gone. While it isn't as sharp as my PG27UCDM, which is understandable as that display has 166 PPI, while this one has 109 PPI it is noticeably better than any QD-OLED or WOLED monitors with similar PPI. * Eyestrain: I got no eyestrain using this monitor as before I had some cases of eyestrain when I got my previous QD-OLED monitors. * Connectivity: It features 1 x 3,5mm audio jack, 3 x USB ports, 2 x HDMI 2.1 ports, 1 x USB-C with 90W PD, 1 x DP 2.1 80 Gbps port. It does have DSC, that can be disabled by the user, so users with DP 2.1 GPUs can utilize this monitor to it's fullest without relying on DSC and its quirks. * Neo Proximity Sensor: The sensor is sill a bit wonky in detecting the user in front of it. Sometimes it works, sometimes the display was still on when I returned back. It is still a hit and miss. Hopefully this will improve over time. * Stand: I don't like the stand, as it takes way too much space, but this was no concern to me as I generally mount my displays on an arm. * Packaging: It's good and well protected inside the box. Plenty of accessories came with it. * Price: It is very expensive, but will probably go down over time. Conclusion: Is the PG34WCDN worth it? Absolutely if you value these improvements I mentioned in my post. Especially if you also use your monitor to work on it as well. The new RGB stripe with no fringing and fuzzy text alone makes this a good buy. If you only use your monitor to play and watch movies and otherwise have a dedicated work monitor, then less so. Your current QD-OLED/WOLED monitor is more than enough for that task. This will probably be my "endgame" monitor until 34 inch 5K2K displays are released. I am aware that LG is gonna release their 39 inch 5K2K very soon with a more subtile curve, however the dealbreakers for me on LG monitors are that they are actively cooled and their matte display. If you have any questions feel free to ask.

They use the same panel, but the Asus has full DP 2.1 support, where the MSI has limited DP 2.1 support.

I jumped from an MSI 34” QD-OLED to the LG 45” 5k2k. The LG gets brighter for sure so HDR might be an upgrade for you. I’m not that sensitive to color accuracy so they’d have to be side by side for me to notice the difference. I was worried going from glossy to matte screen but turns out it’s not that much of a difference for my use. Ultimately, the screen size and resolution outweigh anything the MSI could potentially do better.
