rMBP with external Dell U2414H

[red-5]

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 .

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.

Yes it did originally but I did the forced RGB thing and its now showing like this:

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?

 

[Mr. Retrofire]

Did you change the font smoothing?

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

Hi,

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