I have a GPU: g1 gaming 980ti and a Monitor: Acer GN246HL 24" 1ms 144Hz. I installed new case fans last week, (I disconnected all cables from my computer and monitor) when i booted up my custom built pc I started to have the issue where the error sign on my monitor would appear saying "incorrect cable. Please use the dual link DVI cable that came with your monitor" . Ive been running my computer on 120hz ever since i built it, and now its all pixeled and in order to view my display correctly i have to change the refresh rate to 60hz. I contacted Acer and they sent me a new DVI-D cable and i tried it and this error still occurs. I have all the latest drivers. What can be the possible issue?
