Not really. If your laptop screen is only 720p and your new display is 1080p or above, your frame rate is going to drop drastically. But my question is why do you need a 144hz monitor if you have that laptop? If you have some extra cash, don't spend them on a 144hz monitor, spend them on a better gaming laptop if you want. Not sure what games you'll be playing, but if it's CSGO, believe me, it's not worth it.
