I just upgraded to a 144hz monitor by asus and straight away jumping into csgo i realise when i'm moving a lot with my camera there is a weird affect that happens, the black colours on the boxes become darker and have a grain to them and corners of walls have a slight black line about a cm thick when i move my camera left and right sometimes this colour is purple depending on the colour of the wall, also objects have a transparent white ghost to them as if the monitor cannot keep up with the objects form, an example of this in the image below shows the ghosting but i cannot record the other problems as my camera does not seem to pick them up. Here is the photo:
