rMBP Mid 2014 External Display Fudgy

[bertone_in]

Hello everyone!

Recently I purchased a used rMBP Mid 2014 13'' and tried connecting external display LG 27MP55 FullHD.
I used HDMI cable, as soon as I mirrored the display, I noticed that everything looks "fudgy" and "crispy"
I would upload screenshots but I can't because it looks nice when seeing from PC or my rMBP and not external display. I hope you understand what Im trying to say. The closest I could explain is, everything looks like the anti aliasing option - crisp for text in Photoshop. I checked the resolution a couple of times in System Preferences > Displays and it is 1920x1080, 1080p, the native resolution of external display.

To be more precise, everthing looks aliased.

Just wondering, but...
If you go to the "displays" pref pane, do you have the option to adjust "overscan"?
IF you have that option, what happens if you adjust it?

Nope, I do not have that option unfortunately.
[doublepost=1514047407][/doublepost]I'm really trying my best to be as specific and precise as I can in describing my issue but my written English is bad,

basically all my fonts are rendered as "aliased" instead "being anti-aliased". the overall quality of fonts is really bad, the edges etc. Its like comparing text written in photoshop and web fonts.

my monitor is 27MP55 LG Full HD, maybe I need a newer monitor since the display of MacBook is Retina?

But I think it should work with this one, I know it can't be like retina, but this is really ugly.
