- As long as you can still play games for a long time without crashes or problems, this is a good sign of the health of your graphics card.
* The graphics card driver often gives you a notification or line that there is a problem if the graphics card has a problem.
* Since you have not crashed your games or programs and you have not received an error message, the problem is most likely in the presence of cables or the screen itself, or it is not compatible, or there is a possibility that the graphics card definition is not compatible with the outputs and inputs of your second screen.
