I bought the Dell S3423DWC for home and I run a 38 version at work. Connect via USBC which provides power - built in KVMs / and spend most of my time with spreadsheets and/or creating wireframes/screen designs for systems to show clients. I’ve loved it. I’ve had one “issue” if you can even call it that 1 screen sharing and showing the wireframes - if I’m on my 34 or 38 and they’re on a normal screen it’s caused a few “issues” - it’s fine you can zoom in it’s not a massive problem but worth knowing if you will be showing your designs that people will just complain that it looks to small. Just tell them to get a widescreen 😂 My main issue now is I want one that works for gaming and for work (the dell is fine but I wouldn’t mind getting something above 100hz). It’s hard to find a 34 with a KVM and geared towards gaming (or maybe it’s not and it’s just a me issue) But yeah honestly for work it’s been so good I can’t go back

I guess it depends on the productivity.  I have no trouble doing cartography on the Odyssey G9, but I didn’t care for the brief experience of a 1800r curved Dell.

I’d recommend against a 34 inch ultrawide for Mac. The PPI just isn’t high enough so text will look jagged or blurry. You can counter this by scaling everything about 50% which causes another issue and that is everything will be to big and you’ll loose a lot of workspace. I’ve sold my 34 inch Dell (which I only owned for about 1.5 year) after 2 weeks of owning a Mac Mini because I couldn’t stand it and went for a 32 inch 16:9 4K monitor. I use it at about 20% scaling (3008px wide if I remember correctly) giving me roughly the same workspace as a 34 inch ultrawide with way sharper text. However since you already use a 27inch 1440p the PPI of a 3440x1440 34inch will be rough the same so if the text currently doesn’t bother you then it could be fine.

I went from a 34 inch 3440x1440 ultrawide from dell to a 32 inch LG glossy 4k oled and I wouldnt go back. Ultrawide is good for sim games and productivity but kinda shitty in other games, at least for me. The standard aspect ratio of 16x9 or 10 is perfect

Tbh I had the same dilemma. I had a dell 34inch 3440x1440 monitor( not oled though) , I thought 16:9 was a thing of the past for me but I was dead wrong. The moment I fired up my 321urx I just fell in love with it.

Ich hatte erst einen Ultrawide von Dell und danach einen BenQ, beide die Auflösung von 3440x1440. Den BenQ habe ich mir ganz bewusst geholt, denn er besitzt über Picture by Picture die Möglichkeit durch 2 Quellen angesteuert zu werden und teilt das Bild dann in 16:9 und 5:9. Im Homeoffice verwende ich den Monitor mit 21:9, beim zocken die aufgeteilte Variante (um dann auf dem 2: Bildteil andere Inhalte laufen zu lassen).

I do not game but I do have a dual monitor system a 34 widescreen and a 25 vertical one. If you check my timeline you will find the pic. the 34 is.a Dell 3440\*1440 max res and another one is just FHD.

I am running a 4080 Super and I did switch from 3440x1440 monitor. It was and LED/LCD display from Dell so it was a good monitor but it wasn't anything crazy. For me the jump in quality was massive. I'm blown away by how good the OLED panel looks. It's crazy sharp too even with a little DLSS upscaling.
