If I were to finally listen to GazChap (who is sometimes right about things) and buy an external monitor so that I'm not screwing myself up to look at my laptop screen 12 hours a day, what would I need to be looking at? I'm so long out of the world of tech hardware I don't know my HDMI from my ... see, I don't even know how to finish this sentence.
My laptop is a Dell XPS 15 and does have a HDMI port, if that helps. My screen resolution is 1920 x 1080 if that matters. Is it much of a muchness these days? IDK what I'm doing.
Thanks in advance
