Forget ASUS and ROG alongside MSI because they already did it but the latest brand to honor a “3-Year Burn-In Warranty” for OLED gaming monitors has been announced and it is GIGABYTE and AORUS.
The updated lineup now includes these 6 models of CO49DQ, FO32U2P, FO32U2, FO27Q3, MO34WQC2, and MO34WQC so users of these models will finally have true peace of mind of knowing their monitor will uphold the standard AORUS themselves have put forward.
For the locals, if you really want the final legit answer on whether your purchase is covered by retailers/resellers or by the official channel, you better go and ask the folks who sold to you in the first place.
