Just my two cents: I’ve had occasional problems with games through steam on dual monitors. Things like losing mouse focus or changing resolution on the other monitor (though that hasn’t happened for a long time).

Monitors are old Asus. I won’t bother looking up the models as I’m sure they’re outdated

I much prefer Multi-Monitor on vesa arms. Works better with the way I work, less hassle in games that don’t like unusual aspect ratios.

10-year old 40" 4K in standard 16:9 ratio. way less neck swivel than two 24" side-by-side and way more screen real estate. 60 Hz max, runs off a $30 RX 570 4 GB. got no HDR, 100+ Hz, freesync, and other rich-people-stuff.

to me ultrawides are like what I have, only they chopped off like a third of the vertical resolution and they want more money for it.

I’m a sucker for window managers, so my preference is towards more displays, rather than bigger ones. It’s mostly been dual horizontal setup, but I’ve rocked a triple vertical setup once that’s been absolutely glorious for browser, terminal, and email client.

Gamingwise I would also suggest sticking to a multimonitor setup. It’s easier to drive a smaller resolution.

OLED is a physical thing - OS and userspace doesn’t care about it. HDR - not absolutely sure as I don’t have a monitor to test, but I’ve definitely seen wlroots merge support for it.

I’ve tried both and I prefer Ultrawide for the following reasons:

• Less cables. Cable management is already hard enough as it is.
• No borders in between screens. Looks amazing when watching movies and for gaming.

My current monitor is a GIGABYTE G34WQC.

works fine on KDE, I use a 34" and wouldn’t go back to a two monitor setup. Maybe two ultra-wides stacked vertically? But not 16:9.

I do use kwin with tiled windows, btw, with the new Krohnkite.

I use a 49" ultrawide. I find a window manger work very well with it.

5120x1440p

Edit: one downside is getting proper wallpapers for it that are not stretched or cut

My ultra wide monitor has worked perfectly from day one on Linux.

Currently I’m running an LG and Gnome 42ish, if I recall.

But Linux has had excellent support for ultra wide monitors since before I started being able to afford ultra wide monitors.

I would kill for a 32:10 monitor

I went for a 27" 1440p w/ 24", but that’s because I had the 24" laying around.

I use an ultrawide at work, and it’s fine, but I generally just use it like two monitors anyway, so for productivity I’d prefer two monitors so I’m not screwed when one dies. But I haven’t done any gaming on that monitor, so I’m not sure how the extra real estate would feel for the games I play.

I’m considering replacing my 24" and am considering another 16:9, just bigger (30+") and 4k, though I’m worried my GPU will struggle (6650XT). We’ll see.

Depends on your workload. If you watch movies and game, ultrawide. If you do streaming or web development, dual monitor is like a must. Oled and hdr are also supported, stable on kde and gnome, experimental on xfce. Dual monitor is supported by these, plus cinnamon, mate, lxqt, budgie, pantheon and many window managers. I myself use a 15" laptop bc im poor

What kind of setup do you rock?

Single-monitor, non-ultrawide.

My take is that as long as your monitor is positioned sufficiently-closely to fill a sufficient chunk of your visual arc, you don’t need larger monitors set further back.

If you want to be able to have ready access to the stuff you want to see, it’s a software problem, not a hardware problem. Instead of having a ton of displays constantly showing stuff, where you’re only looking at a fraction of it, you want to make it easy to switch to the stuff you do want to see.

Like, I’ve seen people who have a monitor that they’re writing code on displaying something like Visual Studio. It’s got a tiny portal into code, and then the entire surrounding area is filled with widgets showing information about that code, lists of files, etc, that’s mostly being ignored, where the user is only using a tiny portion of the display’s space at once. I think that that’s a sign of mis-designed software:

The part where I can clearly read text is a comparatively-narrow cone in front of my eyes. Rather than turning my head and eyes for productivity stuff, I’d rather have software aimed at rapidly letting me put what I want to see into that cone, and if it’s multiple things, to switch among them.

Also, if you use a laptop at all on the go, you’ve got limited options as to a ton of monitor space, so you probably want a workflow that works with that unless you’re willing to alter your workflow on the go.

When would I consider an ultrawide or many-monitor setup? Well, there are some types of games where filling peripheral vision is useful. People have had many-monitor flight sim sets for a long time.

If I were really into a particular genre of game that did that, I might consider it.

Problem is, that competes with VR headsets, and in general, I think that VR headsets compete pretty favorably for that use case in 2025. Some flight and racing sim fans have physical hardware, and VR doesn’t permit for interaction with those controls:

But that’s really the only drawback, and I think that the people who build rigs like that are a very small niche: they’re spending hundreds or thousands of dollars and lots of configuration and setup time on controls for a single game.

And HMDs aren’t, in my opinion, really suitable as a general-purpose monitor replacement in 2025, so can’t just use VR headsets or whatever everywhere.

So my take is probably “single monitor positioned relatively-close to eyes”. My monitor is on one of those monitor mount arms, floats over my keyboard. If one wants to fill one’s peripheral vision for video games, probably use a VR headset for that.

oled monitor

I really like the contrast on these, was waiting a long time for these to come down in price. But one caveat which may-or-may not matter to you: OLED monitors in 2025 do not deal well with variable refresh rate (VRR, FreeSync, GSync, etc). When the refresh rate changes, it messes with the brightness momentarily. I am pretty sure that this is not a fundamental limitation, but as best as I can tell from reading, it’s not an issue that’s been eliminated by any monitor manufacturer. I’d guess that there are a limited number of OLED controllers out there, rather fewer than monitor manufacturers, so not that surprising that issues would be common across manufacturers)

Once you go UW, you never go back…

Just try it out haha

I use a 34" UW as my main and a 24" as my secondary works great.

Ultra wide is better. If enough space an ultra wide and another 16:9 monitor. Games look so nice 21:9 and wider without the bezels of the older solution for ultra wide with multi monitors
