I feel so embarrassed for asking this but I have no idea what looks right and what looks stupid 
We have a wall in our sitting room with an ikea TV bench [http://www.ikea.com/gb/en/catalog/products/80133930 this one] in grey. Our TV (which is quite big) sits on the top.
We have about 3 feet either side of it.
I can't work out whether it looks clean and minimalist or really bare!
What could I do with pictures? One above the TV would look stupid but some either side? Or will it just look a mess.
The other walls have patio doors, or an Ikea Expedit unit on so no realy space for pictures there either.
