Question: High Sierra problem with external monitor

I literally just installed High Sierra and now my Samsung monitor doesn't work. It's 2 weeks old, brand new, working fine. Only after I installed new OS does it now have black and white stripes across it. I called Apple and they tried but couldn't help me. I've read there are multiple others with same issue. Apple needs to fix this asap. Right now I can't use it at all and it was perfectly fine right before I installed it. Now I have to see if I can return it. I feel like Apple needs to fix it quickly.
