Hello everyone. I'm making this thread because I'm looking for help. I'm desperate and I've looked everywhere for a solution to my problem. Three days ago I bought an 24" external screen (ACER R231bmid) for my macbook pro retina 13" (mid 2014) and I get some very very bad font rendering with this monitor. The text is blurry and while I now have more space on the screen it doesn't look like a HD screen at all. I tried a lot of things to solve this problem : - I force the use of RGB mode. - I used the display calibrator assistant. - I used many cables --> Hdmi/Hdmi ; Thunderbolt/DVI ; Hdmi/VGA. - I changed the system font to lucida Grande. Nothing worked. I realized while I was making my research that this a very recurring issue with macbooks. I don't really know what to do now and to be honest everytime I use the external monitor and get used to it a little bit, when I go back to the retina display it makes me feel like I'm using some advanced alien technology. That says a lot ... Now I have two questions for you guys : Anyone has any other idea that what I have already tried ? Is it possible that my acer screen simply kinda sucks ? Is there another 24" monitor I can get in order to have a clear display ? I've read somewhere that my macbook won't be able to handle 4K screen. thank you in advance and please excuse my english , it's not my first language so I might have made some miss steak.
