Eu uso um Dell U3421WE UltraSharp Curved (3440 x 1440). Comprei na época da pandemia. Deve existir modelo melhor hoje, mas o tamanho acho excelente. Eu gosto bastante.

I recently got a 34" Curved Dell Ultrasharp. I was a little bit worried that I would prefer my dual 27" setup, but I really love it as a solo monitor. I mostly play Path of Exile at this stage of my life with the occasional CS2 or single-player game like Cyberpunk or Oblivion. All my games have supported the 21:9 ratio just fine, but of course not every game does. I also do lots of web browsing while watching YouTube or sports. The curved 34" is perfect for everyday usage. My only compliant is the alt-tab I need to do during some games with a solo monitor. I might end up putting a 27" above the 34" as a secondary at some point, but I don't think I could go to a smaller primary monitor in the future. Maybe upgrade to a 42" LG C# years down the road, but the 3440x1440 is so incredibly usable.

I recently bought a used 34” Ultrawide Dell from Marketplace. I love the real estate I get. However, Mac Bar is so small and you cannot make it bigger… that’s my sole complaint since I use it for work purpose.

I'm concerned this would be TOO big. What's your desk setup like and use case? I'm currently in monitor decision paralysis mode myself. I've been using a Dell 34" ultrawide for years that I loved. I decided to finally treat myself to a new, bigger monitor and found a smoking deal on a 49" G9. I hated it at first. It felt too big and I couldn't figure out a solution for blurry text on my mac, so I immediately ordered a Dell 40" 5K2K. Over the next few days while waiting for the Dell to be delivered, I got used to the 49" and was starting to like it. The Dell showed last night and while I am in love with the crisp display, it now feels small and tbh, I prefer the additional width over height. I'm going to give it a few days to see how I like it, but I'm considering trying something else or going back to the 49" and dealing with the blurry text.

That's the post I needed, people from /r/oled_gaming are obnoxious to the point of being jerks to anyone who questions their OLED religion. I'm currently using an ultrawide curved Dell 34” and am looking towards an upgrade that I can use with Thunderbolt. This 40” Dell monitor seems great for this, and the KVM will allow me to ditch two devices from my desk, which sounds lovely. Thanks a lot for spending your time on writing this!

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
