So, I woke up this morning and turned on my computer. Found my second monitor isn't working. I attempted to update the drivers for the "unknown device" and it took a while downloading and installing, and during the installation process, it popped up! Great! And then immediate disappeared again. The drivers did not install properly. I was given a Code 28. So, I tried it again. Same thing. Three times. I go to the Acer website to manually download and install, and found that for G236HL, there are no drivers. Not sure why this would be the case on Acer's website. Anyway, this is where I am now. Any ideas? Thanks!
