dsi or hdmi

[fred9000]

i plan to put a lcd display in my box   , i have a rpi 4   , my idea is  to let the rpi already in the same possision in the case  ( old marantz  )   and use an  extender between rpi and display , but the only extender i find is dsi is for rpi 5  , is a hdmi would be better  in this way  ? ,  and is hdmi are support , i asume dsi is the prefer method

What make and model is the LCD display?

i know the touch 2  7" are support but in the marantz box i mod   i have the exact place to use the 7.9 " waveshare  without    saw  the front   pannel  which is going to  loose the concept of keeping  the original box "look"  marantz sr-8000 empty enclosure ,   now i dont know what to chose between dsi or hdmi
