I regret getting the WQHD (2560x1440) screen on my X1 Carbon 7th gen. Text is too small to read without scaling, and I haven't figured out how to configure consistent scaling behavior across Wayland and XWayland applications.

FHD is plenty on a 14" screen.

I have the same configuration and leave display scaling at 100%, but set the font scaling factor to 1.5 in the Gnome Tweak Tool. In this way, all fonts in Wayland and XWayland apps have the right size and nothing is blurry. Only controls like window borders are a bit smaller than intended by the designer, but I actually prefer it that way because it's more compact.

Likewise (scaling factor 1.4 here). I find that quite usable.

Counterpoint, I also got the WQHD screen, on my T480, and it's great. I absolutely love the print-quality text in my terminals. "Scaling" is not a problem at all - I eventually figured out that the way to get flawless graphics is to ignore all "scaling" settings and simply throw an xrandr command in .xinitrc that forces the DPI to its correct value (144). For some strange reason X11 ignores the real screen DPI (which it knows perfectly well!) and forces it to 96, which is broken behaviour in 2020. Most of the rest of the software ecosystem is a team player, and respects the DPI setting (things that don't are broken - I believe GTK requires an environment variable, but QT respects it). "Scaling" is a broken concept - 12pt font should render at 12pts, no matter your screen size or resolution.

I have an X1 Carbon 7th gen with a 4k screen (3840x2160). I run it at 2x scaling on Wayland (sway) and I haven't had any issues with native Wayland apps. X apps are rendered at 1x and upscaled, making them blocky or blurry. Apparently there are some apps like Spotify that ignore scaling settings and always render at 1x, but I haven't run into them.

There is a fix in progress for XWayland scaling: https://github.com/swaywm/wlroots/pull/2064

I'm assuming you're a developer (just because this is HN) - curious to know what kind of battery life do get with a UHD screen?

I use Windows, so consistent scaling wouldn't be an issue. I was more wondering with regards to battery life.

I'm pretty sure I'd prefer a WQHD screen to FHD, but am also pretty sure I wouldn't get any benefit of going to UHD. But at the same time, if WQHD has a significant impact on battery life, I'd probably stick with FHD.

I have a T480s with a 14" FHD (1920x1080) screen and the experience isn't good either. Wayland apps work with fractional 1.25X scaling but are laggy and have odd graphical glitches. XWayland apps are just blurry.

I think 1920x1080 is the perfect native resolution for 14", without scaling. It's a bit small on first look but you're closer to laptop screen than you're to a real monitor, so that turns out just fine for me.
