First off, even most monitors that claim 1-2ms are typically more like 4ms actual grey to grey, because LCD tech takes a full 8ms for a full refresh on a 60Hz panel (or 4ms grey to grey).
Second, ghosting is typically a result of motion blur, which is not the same as refresh rate.
In other words, to get a good display for gaming you need to look at refresh, input lag, AND motion handling capability. Other things like 4k, high refresh rate, or HDR, are just bells and whistles by comparison.
There are sites that thoroughly test monitors and TVs for all those things. The one I use is RTINGS.com. Being as you didn't even mention what monitor you're using though, I cannot check it's specs.
