colors displayed in negative

[matseba]

Good morning I just installed autocad 2017 on my new notebook. opening autocad with the background of the default color (black) when drawing the lines are displayed with the color to the negative or if drawing lines with the red color to video the blue view and vice versa. if drawing in yellow I visualize in cyan and vice versa, so also for all other colors. Please help me. Thank you.

Thank you both. the problem is always present unfortunately.
I will try to do a downgrade of the video card since a few days ago I was updated. Thank you.

obviously you did not answer the first question when selections or always?an image would help to circumstate the situation.
if you then attach a file with a line and who opens it sees the correct colors you can exclude a set of autocad and think about the video card

Good morning I answered. However when drawing in the model space with black background for example a line happens this:
white line remains white;
line red color me draws blue color
line blue color me draws red color
line of yellow color me draws color cyan
color line cyan me draws it yellow color
And so on.
I hope I was clear not when I select them but when I draw. Thank you.
I think it's a video card problem, too.

Good morning I followed the procedure indicated or I disabled the accelerator of the video card and now everything is back ok. the problem is probably the video card that after the update is no longer compatible with autocad.
a question I might have with disabling the graphic accelerator? I use autocad to make only 2d. Thank you.
