I want to raise my 530 up off of the floor about 2-3 inches. However, I do not want to build an entire base because I do not wat the wheels of the tv to touch the base. So can I slide a couple of 2x4's under each corner of the tv, or will the lack of support in the middle cause any damage? I can not build a rectangle frame b/c my entertainment centers base molding has an arch cut in the bottom and you would be able to see the wood. Thanks!
