Perspective page update issue?

I am running Ignition Platform 8.1.22 and have madfe a perspective screen in a coordinate container. It has 3 machine values displayed for performance metrics. Machine speed operator speed etc. Organized by Last cycle, Last hour AV and Shift Av. Im running into a very frustrating issue where a few of my LED Displays are .2 seconds off between my browser and the HMI, (the URL displayed on a rasberry pi and TV) and when opening my designer the web is .01 seconds off. How on earth, where do i start? I have nothing setup for uniqe logins or anything like that.
