I'm thinking of upgrading my monitor. I currently have an 11-year-old 17" monitor with a 5:4 aspect ratio. I'd like something around 27" and a 16:9 ratio. I have zero interest in video games or streaming movies... my main interest is Photoshop. I've budgeted $500-$600, but could go a bit higher if I must. And I already have a calibration device. I've read several online reviews and am leaning towards Dell, but I'm wondering if anyone here has any suggestions of brands or models that you particularly like? Thanks.
