The Besta from Ikea is the most easily done to fit any space this is the one mentioned above,

Thanks, for the reply. Yes, I am hoping to feature the mdf on the wall. I am not sure like which one to choose and how to make it look better. I want to make use of the entire wall with cabinets. But, I am open to other options also. There is also a pillar next to the wall on the left side. I also want to make use of the space between pillar and wall (like glass cabinets). Needs your inputs, if you can share some images, that will be great.

How can we decorate this wall with a TV unit,suggest us

Hi Ash! Since the size of the room is not mentioned, I would suggest you to check out this video. And if the room is small in size, I would recommend you to opt for TV unit with floating shelves, as this will save the floor space to an extent. Hope this helps.
