My monitor goes black after a few seconds

I don't know why but my monitor goes black after a few seconds. I have to turn it off and on but it goes black again. Because the monitor uses VGA I bought an adapter from Axagon. Could you please help me?

Probably faulty monitor or adapter
can you check the monitor on another system/laptop with native VGA support?

I don't know why, but after some time it started working again. If it would stopped working again, I'll let you know. Even so, thank you for your time.
