Which monitor will u prefer IPS or TN as both have their pros and cons.
IPS : for picture quality, viewing angles
TN : response time, refresh rate and gaming
LG 27UD68P (IPS ), Dell IN2030M. (TN).
Never going back to TN.
I prefer matte panels, but If I compare the LG monitor with a macbook pro 2017 screen, then despite being glossy, MBP has slightly better color reproduction (probably because of DCP-3 vs sRGB in LG)
OLED have burn-in issues for displaying static images for a long time(normal desktop use). Actually every TV panel has burn in issues to some extent. They explicitly state in the manual not to show static images for a long time.
