Moniter turning off and on completely when pc turns on
So I recently bought a moniter on Amazon and it turned and it looks like it was going to work. I hook it up to my gaming pc I built via hdmi and turn my pc on. Right after the windows logo appeared it the moniter turns off completely and so does the light. It turns on again with the Acer logo then I see a split second of the windows sign in and it repeats the process. I think the problem is the power cable because I compared it to an old computers one and the output is about 1.4A (something like that) compared to about 3.4! I recently bought a new replacement cable and I hope it fixes it but I have a feeling the problem might be something else??
