I have an acer e15-575g. It's an old gaming laptop with a 60hz display. I've read serveral other threads regarding the whole monitor, hdmi versions, etc. All of which were too confusing to me. My laptop does have a VGA port and an hdmi port. Could I possibly get a 144hz monitor and expect "144hz compatibility" ?
Sorry for my bad English.
You need to find out what HDMI version that system has and you can then find out what resolution and refresh rate it can run. There are a few versions of that model Acer, you will need to know specifically what model and what video card you have to find out if it can run at 144hz.
