Just got this telly to replace a Sony 28" widescreen but oh dear! The horizontal linearity is awful, as objects move to the sides of the screen they grow in size. This is really noticeable with horizontally scrolling credits, they arrive at 900mph, move gently across the centre of the screen and then accelerate off the screen again. Is this normal for 32" tubes? The 28" certainly doesn't do it! Any ideas anyone?
