This is a really awkward space! What about trying to build a unit into the corner which seems to be dead space. This could house the television and other bits like dvr,amp etc. The unit could then extend out towards the door in length and in height either up to the start of the window or up to the start of the blinds. I would suggest drawers for toy storage and books above. In this way you leave the windows clear for light plus it looks like you have a pull down screen so the tv would be out of the way of that. This arrangement would also hide all those wires and cables! Ikea have some good examples of storage which you could adapt or copy, such as Besta which illustrates the extended toy storage. http://www.ikea.com/gb/en/catalog/products/S39927155/

can you do search on previous discussions on the dilemma section of Houzz - you will see this often comes up. Bottom line, it is not a good idea as heat and a tv don't go well.

White skirting and cornice might lighten the effect.

Is that even a question? Yes, yes, yes. Otherwise, get a projecter. Project it onto the ceiling. You'll never need to leave your bed (maybe except to the bathroom). Perfect for a lazy Saturday afternoon.
