Question Asus vivobook r540ub bios and nvidia issue

[Arnavv24]

Hello I'm using asus vivobook r540ub, actually I recently updated my bios from asus support website I entered my laptop model and operating system version after that it asked me about model number like is it x540ub or x540ubr I got confused cause mine is r540ub so first I selected x540ub there I searched the softwares but all of them was outdated so then I entered x540ubr there I searched the softwares the drivers there was new and updated so I thought to download all updated drivers and softwares and to install them after that I updated my bios to 308 but then I started facing issues in my graphics first intel uhd then nvidia mx110 now the problem is in my bios I think I installed wrong software that's why my graphics is not working properly in nvidia when I play games it automatically downgrades my resolution to 720p though I have 1080p screen and previously I played same games in 1080p. So what do I do now Please help me with this problem.
