    Hi Guys,

    I am using a late 2013 macbook pro with a new external dell monitor U2414H. I am having similar problems to others whereby the text and fonts on my external display are pixelated quite badly, this is not in relation to going from a retina screen to a non-retina screen as I have other systems with 24 inch monitors that don't look like this. There is clearly a problem.

    I have gone through various diagnosis based on things i've come across online.

    I have:

    • Used different leads
    • HDMI, Mini Display, Mini Display -> HDMI
    • Reset RGB (forced override with Ruby script)
    • Adjusted sharpness and colour with monitors physical display settings

    I don't know what else I can do to get this working or where exactly the problem is coming from.

    Is it an issue with the rMBP or my Dell monitor. If it is the latter I will return the Dell and purchase another monitor, however if its a known issue with the rMBP I will have to just come to terms with the fact that my 2000+ pound computer cannot run an external display :mad:.

    Appreciate your input, thanks!

    Sounds like using HDMI is the issue. If you used a mini-dp to DVI cable my guess is your problems would go away. I have a monitor that when connected via HDMI to HDMI looks horrible (forces "TV mode), but mini-dp to DVI looks great. I picked the cable up on Amazon for about $10. I have a mid 2012 rMBP.

    I am currently using a mini display to mini display port. The dell monitor I've purchased doesn't have a DVI port.

    No problems here with mine connect with a mini display port to display port cable. I forced RGB but I couldn't see a difference.

    So would you say the issue is related to the monitor?

    This is the difference between screens:

    Yeah yours look far better. The fonts on my screen are so bad their literally unreadable for any extended period of time.

    Odd, I have the same monitor (the dell ultra sharp) and I'm also using the included DP to MDP cord and everything looks just fine for me. This probably a silly question, but what resolution setting are you using?

    I have it set to best for display on both the laptop and the external monitor. The external monitors resolution is 1920x1080

    ----------

    Yes I tried this as well.

    @red

    Hi,

    I'm using MBP Mid-2014 with the same monitor, U2414H.
    @ red, did you manage to fix the fonts?
