They can use the screens of any size but only with 1366x768 resolution. That would be better.

Just took a look at Levono.com, played with filters... in the year 2022 you still can buy a model with such screen:

    Part Number 20X1CTO1WWUS1
    Processor : 11th Generation Intel® Core™ i3-1115G4 Processor (3.00 GHz, up to 4.10 GHz with Turbo Boost, 2 Cores, 4 Threads, 6 MB Cache)
    Operating System : Windows 11 Home
    Lenovo recommends Windows 11 Pro for business.
    Graphics : Integrated Intel® UHD Graphics
    Memory : 4 GB DDR4 3200MHz
    Storage : 128 GB PCIe SSD
    Display : 14.0" HD (1366 x 768) anti-glare, 220 nits

I can bet $15 most (as in 99.99%) of the UX/UI designers at Google have at least FHD screens, many of them with 4K screens.
