I need to recommend an iMac and screen size. The problem is they normally scale down the resolution one setting, to see everything better. This is on an older iMac and when you do the resolution still fills out the screen 17". I went to Best Buy and while they didn't have the new ones I checked lowering the resolution and it doesn't scale without distorting or adding black bars to the sides making the viewing area smaller than the screen. Is there no way to lower the resolution and keep it full screen without distortion? Thanks.
