Soldering upgraded ports on a monitor?

Hey all,

Does anyone know if I can just replace the hdmi port on a monitor (asus pb287q) that can display 4k at 60hz on the displayport, but can only do 4k at 30hz on the hdmi port. So that it can display 4k at 60hz through the hdmi. Would it be that simple or is it not bottlenecked at just the port itself? Alternatively, is it possible to hijack the displayport’s 4k60hz video output stream and reroute it onto a hdmi port?

If neither is possible, does anyone know of a decently priced hdmi (source/in) to displayport (out)? Not displayport to hdmi. I tried searching for ages and I only came accross 1 product that could do 4k at 60hz at all, but it was $140/£112.

Thanks a lot guys
