MacOS showing external monitor's size (inch) wrong.
Computer:
MacBook Pro (16-inch, 2019), 2.6 GHz 6-Core Intel Core i7, 16GB of RAM, GPU-AMD Radeon Pro 5300M, Intel UHD Graphics 630.

External Monitor:
LG 27UP850-w, 27 inch, 4K Monitor
---
Problem:
When I go to the "Display" in "About This Mac", MacOS is showing my external monitor as a 31,5 inch monitor (screenshot attached). Because of this issue the only way I can see texts and small details clear is to set the resolution to 1920x1080, other higher resolutions in "Scaled" settings and the "Default for Display" settings makes text and small details blurry/fuzzy.

Question:
Is this a MacOS issue or could it be the monitor manufacturer's issue?
Does anyone having this issue?
What can I do to use my external monitor the way it should be?
