I need the portability and battery life for school, so I want it to be a minimum of 5 hours in battery life, max 2.2kg and a 15 inch display. And the lower the response time of the display, the better it would benefit me as I play moba/fps games.. And it would also be nice if it would be possible to connect to a 144hz monitor, as I do play csgo quite a lot. If you have suggestions, please mention its response time and if connecting it to a 144hz is possible, or provide a link of it. Hope you can help, thanks in advance!
