Hi guys. I want to make an upgrade from my Dell u2715h to a 4k monitor with the same color/performance as the previous monitor. Any recommendations you guys have for a replacement mainly for work as a designer on a mac? Thanks.
Apart from newer models like U2720Q (and maybe expensive and more color-accurate models like UP2718Q), you may find a cheap Dell P2715Q which is technically/practically way better than U2715H and still very good.
I recently bought a BenQ PD2700U, which was a great value. I'm super pleased with it. I do design work, but mostly UI, so calibration is not as sensitive as for other areas. I'd really recommend it if the specs seem to fit.
I suppose there are currently no really good ones out there compatible for 4k designing. Although the awesome article by Bjango is a little outdated, it's still somehow up to date, since there hasn't been any good in 4k displays. The best for now is the Ultrafine from LG which is sold in the Apple Stores.
