Dell UltraSharp U4025QW

I’ll give you an anecdote: my work laptop is an M3 Pro MBP, and my Dell U4025QW works just fine with it over Thunderbolt at 120Hz VRR

Yeah… Not sure of your model (I have the U4025QW), but mine is so close to perfect as a KVM between a Mac and 2 PC’s, if only the KVM had one more USB output port. It takes 3 video inputs, but only 1 dedicated USB output. But oh, one of the video inputs is really Thunderbolt, so you get USB over the same cable and it works… but only if your machine supports this (for many laptops this is fine.) But that’s 2 machines max in the KVM, while the monitor has 3 selectable inputs… It would have been nicer if they could’ve added one more USB output, so you could have KVM match the display input for 3 machines with a single toggle. (I have a Mac, a work desktop, and a gaming desktop, and I can toggle between the Mac (thunderbolt) and one of the PC’s, and the kvm input will follow the display’s. But I have to pick which PC I want to plug the downstream USB cable into… so I bought a little $15 USB A/B switch to help. So Mac keyboard always works, but when switching between gaming PC (hdmi) and work PC (DP) I just have to remember to toggle the A/B switch along with it to make the keyboard go to the right host.)

I’ve been a big fan of the big dell curved displays. The U4025QW has been a solid single monitor

I have a U4025QW and there's a glitch I'm typing here for google to pick up. If my macbook (any macbook, perhaps any computer?) is plugged into the U4025QW and the power goes out, the U4025QW won't get the signal from the laptop and will remain blank. There's two ways to 'fix' this: The first is to unplug the monitor for a long time, perhaps 2 to 4 hours. Sometimes I'll plug it back in at hour 2 and it wasn't long enough and I'll have to start over. The second, and this works reliably, is to unplug the U4025QW, and then also unplug the monitor side of the HDMI cable, and then plug it back in with no signal, and then reinsert the HDMI cable. This gets the U4025QW to receive the signal after as long as the above operation takes, a minute or so. I have had two U4025QW units. The first one was overheating and losing the signal as above on its own. I stopped having overheating issues when I stopped using an undersized UPS. I ran it straight into the wall. But if there's a power outage (i live in an area with monthly power outages), the signal loss operation is how I restore functionality to the U4025QW. I finally got one of those 300 dollar UPS units for the U4025QW and it's been very stable since then. A multi variable episode that took me a very long time to reduce. U4025QW is a great monitor but dont give it bad power and it needs a little love after a power blip.

I have the Dell UltraSharp 40 Curved Thunderbolt™ Hub Monitor (U4025QW). It's very expensive, but the 5120x2160 resolution with the 120hz refresh rate is absolutely worth the cost for me over the long run considering how long I spend looking at the screen while coding. I pair this with my tiling window manager[1] which treats ultrawides as a first class citizen (not all twms do this unfortunately) and I'm very happy with this setup.
