I've hit a bit of an issue whilst finishing off treating the room, so the corners are done top to bottom and there's treatment along all along the walls. Unfortunately I've only been able to place one piece of treatment lengthways (1.2M) over the centre of the desk (2.8M) which doesn't cover above the monitors..
There's wire looms for the lights / plug sockets travelling across the points where I can fit brackets so it's a no go. Question is how much of a problem is it going to be?
How high is the ceiling? I hung a cloud over my desk which hangs off the ceiling by hooks and chains. I hangs down about a foot. Mainly the cloud just needs to add some absorption at the first reflection point.
