Overscan actually loses you some of the resolution you paid for. No matter what, an overscanned image will be softer and potentially noisier than a non-overscanned image. Even if it does a good job at this, it can't be as good as just leaving the signal be. set the background color to paper white if it isn't already the default. So if your TV takes that image, and zooms in on it, it has to readjust every pixel to fit. Dot pitch is a monitor specification that tells you how closely together the. However, if you have a Sharp Aquos TV, Dot by Dot mode might not be available in the menu as Pakman mentioned I couldnt find an option for enabling Dot. The signal you're sending it, either from cable/satellite, Blu-ray or some 4K source, is exactly the same number of pixels as your TV ( yes, 1080i has the same number of pixels as 1080p).
#Sharp aquos dot by dot default 720p#
When a 720p signal is being input, the image will be delivered in full screen. Your TV likely has either 1,920 by 1,080 pixels ("Full HD" 1080p) or 3,840 by 2,160 (Ultra HD or 4K). Dot by Dot (1080i/p only): detects the resolution of the signal and displays an image with the same number of pixels on the screen. The problem is, there's very little reason you should have overscan enabled on your TV today, especially if, now that you've read this article, you're aware that very, very infrequently, you might see something on the edge of the screen that shouldn't be there. This actually continued into the digital era, where early HD broadcasts (especially live ones) would show things in frame that shouldn't be (mic stands, black bars on the edges of footage, etc).
