I connect to laptops:
1. Acer with Intel HD4600
2. Acer with Intel HD (Pentium B960)
This a problem with my laptops? There is no way to check on other equipment yet.
Is there any way to fix this?
Thank you

thanks for the answer. I also came to the conclusion that the problem is in the demagnetization loop.Fudoh wrote:might be a tube damaged in transit. Your first step is very likely to get a degaussing wand and see how the tube reacts to that.
