A:AnswerCheck with Asus to see whether the laptop warrant is worldwide or only in US. If you have bought additional warranty from Best Buy, it is only valid in US. Hope this helps.
A:AnswerThis is a late answer but is meant for anyone else that views this but I have 2 LG 144hz monitors hooked up to my G14 2060. The usb-c adjacent to the hdmi can run one of my monitors at 120hz while the hdmi can run the other monitor at 60hz. Works well for me when developing and modeling.
A:AnswerI’m pretty sure the grey model with the 4900HS and 2060 MQ is not available in the US. I guess you could import it, but that could be expensive.
A:AnswerOnly thing I can think of is whether it is getting overheated from whatever activity you might be using. That could be airflow under the system depending on what you're resting it on, but it could also be thermal paste just straight up failing. Assuming it is not the former, then time to activate that warranty and get it checked out.
