Correct, but both can be called 2160p just because of their vertical resolution. Overall both terms don’t matter in gaming because aspect ratio can be changed on the fly (on PC) depending on the output device. Haven’t touched a console in years but I assume they are stuck with a 16:9 aspect ratio no matter what they are playing on?
Comment on 4k is not 2160p - heard it here first!
billwashere@lemmy.world 1 year agoI had to go digging but 3840x2160 is both 2160p AND 4k UHD. 4096x2160 is something called 4K DCI which is more of a camera or film industry thing and is rarely used for things like TVs or video games.

1080p 1080i 720p (IE the i/p suffix) denotes a SMPTE resolution and timing.
HD/FHD/UHD (720,1080,2160 respectively) also denote SMPTE resolutions and timings.
These are SMPTE ST2036-1 standards, which are 16:9 and have defined (but not arbitrary) frame rates up to 120fps.
4k DCI is still a SMPTE timing, but used for cinema and is generally 24fps (tho can be 48fps for 2k DCI).
It’s SMPTE.
There are other “4k” standards, but not nearly as common.
If you have arbitrary resolutions or timings outside of the SMPTE standards, and generally fall into VESA standard resolution/timings or custom EDID resolution/timings.
Chances are your computer is actually running 1920x1080@60 CVT-RB rather than 1080p60.
Whilst 1080p60 and 1920x1080@60 seem like they should be the same, some displays (and devices) might only support SMPTE timings or VESA timings.
So, although a display is 1920x1080 it might expect SMPTE, but the device can only output VESA.
