Hello. I have the ASUS ROG G751JY gaming laptop and I recently found out the "Create custom resolution" option in the NVIDIA control panel. When I clicked it, it gave me a warning and what it said in a nutshell was: "If you use this setting, since you go above what the manufacturer had planned for this monitor you may cause your monitor to have increased voltage, failure in sync, corrupt the BIOS, have high temperatures etc". I'm not interested in using 2K or 4K resolutions as that would destroy my frames ( and this monitor is a 1080p native so I don't think it can go more than that ) but I am interested in using a 120-140Hz ( whatever>60 Hz at least ) refresh rate. How safe is this? Which setting is safe ( if it's any safe at all )? It also wrote that this voids my warranty thus I would not like my monitor to be destroyed or malfunction. I'd like to mention that I play intense games such as Rainbow Six: Siege, GTA V, ( the upcoming ) Battlefield 1 etc. and I put the settings as high as my PC can have more than at least 40 FPS ( please note that this model doesn't have G-SYNC installed ). The monitor is named in the device manager as "Generic PnP" in case you're wondering. Thank you for your time.
