Hello, I have a DELL laptop (Latitude E6530). Not the best for photography maybe. I've ordered a screen calibration tool (Spyder 5 pro) but beside this, I'm looking into options to get a better screen. I see different options, but I'm not sure which ones are realistic. Any advice? 1) Buy a good quality screen (which one?) and connect it to my laptop, will it change something? Is that even possible? 2) Buying a whole new computer to work on my pictures? Thank you!
