I think you may be mistaken about veneer. Veneer is a very thin layer of, in this case, wood that is glued over a less attractive piece of wood, to give it a better look.

HI -- If you could find a squared console or buffet cabinet that will fit against the side of your big cabinet that is close to the style and color of the big cabinet , then place the TV on top or hang the TV on the wall with a swing bracket . Then add a, just as long, floating shelf over top of the TV .at a level no higher than the top of the big cabinet. Ikea might have something that would work for you that is black or something you could paint to match your big cabinet.

your choice of furniture pallet is realy beautiful.

Hi Abhinav, Something as simple as a back panel with wood or marble veneer and floor cabinets can give your TV unit a minimalistic look. To give you more specific ideas, do share more details regarding your requirement.
