Hi everyone. I was looking for an answer but can't find similar topic anywhere (if anyone knows - please send me a link). I have got an issue with auto cad on iMac (Retina 5K, 27-inch 2019). Lines on the screen looks very think that sometimes (especially when is bright day) I can't see them properly and have to be really close to the screen. I tried to change background to different colours but it doesn't help. I have compared it to my other friends computers and it seems like I am the only one with this issue. The only explanation I had is because of high resolution of the screen lines are super thin but one of my friend has similar computer and on his screen lines looks perfect.
