I have a Panasonic TX-L22X20B and the text appears distorted (very disturbing to read). I have a Radeon HD 5450 graphics card (which isn't the problem). I have tried various things such as changing brightness, contrast and sharpness which did make things slightly better. However it is still disturbing to look at the screen. I am using a HDMI connection with 1920 x 1080 resolution. When I connect a PC cable it seems just fine but the resolution is lower and the display is large.
