Hi, I have tried different resolutions, aspect ratios and projector distance from screen (wall in my case) to get full viewable screen without extra grey light bars on all four side, but it is always there and my viewable area is always within this extra light bars. Is this normal? is there a way to eliminate this and have no borders. PS This is an old benq projector MP620C. I tried changing resolution and aspect ratio on projector as well as on laptop. Thanks!
