and replace it with HDMI. Otherwise you'll need a converter on each end of the RGBHV cable. By definition:
RGBHV cables provide an easy solution for breaking out the individual lines of signal to BNC connectors for easy adapting to displays with BNC inputs.
The key word is BNC which is an analog signal. Modern components will have HDMI ports. You'll have to convert the digital signal to analog, then back to digital.

I have a new aptartment pre-wired for a home theater with all the components to go in an adjacent closet, leaving just the tv and inwall speakers in the living room. Thing is, the installers wired it with RBGHV.
Does anybody know how this will effect my TV's performance and how it should effect my choices of tv, av receiver, and video player? The installer said it would support 1080p. Another company said only 480p. Can that be right?
Read a lot of reviews and articles, but haven't got any clarity of where I go from here. Anyone else using RGBHV? Would really appreciate some shared knowledge.
