This item didn't fit me. I watched a few YouTube videos to see what I can change on my computer to make it work, but I couldn't get the screen to expand other than using them as mirror images. Finally a computer technician came to me to try to get it working and he advised me that splitters often don't work and it's better to have two separate cables from the computer. Unfortunately I waited 2 days too long to send it back, so I can't return it either. :(
