Extreme Mouse Acceleration When Playing Minecraft

I just recently got a 4k monitor and it needed some mouse acceleration for me to get around it faster or else the mouse goes really slow. But when I game I just turn on raw input and it does not affect it but when I play Minecraft my sensitivity moves super fast making it unable to play with. It's hard to pinpoint one location when my character is turning so fast I've searched all over the internet for a fix and I found one that turns mouse acceleration off but without it It takes a long time to get around my desktop.
