Hello, Last week I purchased a MacBook Pro Mid 2015 15" laptop, along with a Dell s2415h 24" External Monitor and the quality is dreadful on the external display. I am using a HDMI to HDMI cable, that came straight out of the Dell Box. Things I've tried: Messing with the display sharpness settings(text was slightly better turning sharpness down) Enabling font smoothing via the terminal (did nothing) Using a higher quality HDMI cable (did nothing) Enabling LCD smoothing on the system preferences tab(did nothing) Messed around with colour settings on the display and the Macbook Anymore suggestions? The colour seems very off also, I've messed around with the colour settings on the Macbook and the display but it didn't help. It's like a orangey/dirty tint to the screen. This is very annoying as I do web design and colours and everything I design on the external monitor looks entirely different on the MBP. I'm in the process of downloading El Capitan, as it didn't come pre-installed to see if that solves anything. I wonder if I need a 4K monitor to get a better experience? But surely this display can't be as good as it gets for a £160 monitor. And I am not splashing out £600-800 on a Apple Thunderbolt display after purchasing a £1300 laptop. It ruins the whole experience of using Apple products also, which are meant to feel crisp and of a higher quality. Any suggestions please, or if anyone else has experienced this or is it just normal? Thanks.
