i have a U2718Q and an imac pro with the LG 5k panel. the dell is blurry/sparkly by comparison (perhaps from the matte). is the LG 5k standalone display (now discontinued, but still available) better?
i found this: https://forums.macrumors.com/threads/imac-5k-versus-lg-5k.2172112/
trying really hard not to have to spend $6k on that stupid new apple monitor just to get an equivalently good display after i sell this imac
