Hello Corinne
First of all, these curved screens have been or are mainly used by gamers (i.e. inveterate video game players).
The main disadvantage of its screens is that they are not very high, they are mostly wide. Draw the dimensions with a cardboard or newspaper and you'll see.
1°) The lack of height is very annoying under Solidworks and a lot of other software because if you look at the space taken up at the top by the tabs then by the banner of your part or assembly and at the bottom in any case you will see that the problem is first of all the height for the comfort of work.
2°) the visual consequences are significant (these are screens that tire more than others and beware of those who have glasses, especially with progressive lenses). The problem that is not immediately visible is when your eye sweeps horizontally there is a deformation when it is inscriptions such as MEP drawings or others. As already said, these are gaming screens, because for these people everything happens all the time in the center of the screen, the rest of the other two thirds (left and right) are only used for the tunneling effect (it's this tunneling effect that makes the game "immersive").
You have to compare it to the windshield of a car where you will see that if you are focused on the road the lateral field of vision decreases. And the faster it goes, the more useless the side becomes (cf. the windshields of the TGV).
A good alternative, even if it seems weird, are screens from 34" to 38". (Note: one of our colleagues on this forum works all day with a 14 inch, I don't know how he does it, but he's happy.
Personally, I have two 26'' screens side by side. This solves the problem of having for example the current part in front of me and all the other parts, drawing, ASM on the other screen including Excel for example. But for me, who works all the time on assemblies in addition to parts, I don't have enough room with my two 26-inch models, which is why I'm going to buy two screens in 32 or 39 inches.
On the other hand, be careful with these large screens that you can, depending on the screen support, put it as low as possible. The bottom of your screen must be at least 8 cm from your worktop, otherwise beware of turtle neck syndrome.
For the size of the screen, it should be noted that graphic designers favor large screens, but none of them use curved screens. We are graphic designers of a particular kind if you look closely.
You will find attached an inch / cm conversion table for the size of the screens (the diagonal is always expressed in inches)
