What's y'all's preference?
Flat works for me up to about 27". From there I prefer a slightly curved monitor. I have used a lot of different sizes, counts, curved, and flat and settled on this. At this 38" size, i wouldn't use flat. Any bigger than this and I feel like I need to start moving around the see the whole screen.
I've gone back to flat from curved for my work setup. Horizontal lines can look off when using curved.
Agreed and that's what puts me in the middle. smaller screens flat. larger screens curved but small curve. There is a curve spec and some have a very pronouced curve for immersion while gaming. Some like mine have a slight curve intended for productivity work. 38" with less curvature still looks relatively flat when focusing on smaller areas.
Mine doesn't look as curved in real life as that picture above.

I am loving this one.
if you want straight, curved, and bigger than Bryan's...

I find multiple monitors are better than 1 large one. Easier to organize windows when working on projects.
@Bryan We are twins. I have Samsung Odyssey G9 also (not Neo, though). I really like it. I use an app called WinDock to separate it into 3 virtual monitors for easy window docking. 50% of the screen in the center is my main "virtual" monitor, and the 2 sides have 25% for other accessory apps, terminals, etc.

@Mark I agree, but have found that 3 virtual monitors is working great because I can change the size any time I want. If you use an app like WinDock it helps make docking windows a lot easier.
I had 5 at one point. Then I realized that I'm a terrible multitasker and much better when focused so dropped back to one 38".
@Kory I had 6 once and it started to hurt my neck moving around so much. I find that 3 is the perfect fit (in my case 1 monitor split into 3 virtual) because my head can be facing forward most of the day for my primary work with 2 side monitors for accessory stuff. It gives less neck stress.
@Heber, I also have an LG curved next to it so I am close to 7'-0" of screen. 😊 I will check out that WinDock. Thank you
