U405-S2856 loses contact with external monitor

\015 Few times a day, my U405-S2856 make a sound , then the external video screen shows "no signal" for a few seconds, After that the the picture returns with a message on the lower right of the screen that I'm not working in optimal resolution, it happens a few times in a row and than everything gets back to normal. I have tried changing the resolution to the recommended 'optimal resolution' but it still happens. Any advice is highly appreciated. Thanks\015
