Sorry, but this is just wrong.
It is NOT easy to find enterprise grade laptops with 3K 120Hz OLED. That is a very, very expensive option on very select workstation grade laptops, if you can even get it.
When purchasing for large organisations, there are lots of other stuff on the list of requirements: 3 year on-site warranty, "keep your hard drive", longer model lifecycles, precofigurable BIOS and loads of other stuff.
What is offered on consumer-grade gaming laptops does not in any way or form compare with enterprise-grade laptops.
4K screen is offered on Dell Pro Precision 16". The only 3K screen is on the old Latitude 7350.
HP offers 2.8K on the pricey EliteBook X, Ultra G1 and ZBook Ultra G1.
Lenovo offeres 3K on Thinkpad T1g, P14s and P16
None of these laptops starts below $3K and I don't think any of them have OLED.
