Label the short side with the tely's measurement and the long side with your chair's distance. Divide short by long and use a calculator to calculate the arc tangent, tan [-1], or tan inv. That's the magic angle to make sure the new flat panel looks the same size as the old tube. Write it down in the narrow corner. Figure out how much closer to the wall you can put the new tely and run the calculations backwards to get the new tely's new height (of the viewing area).

Or ... I could buy one with the same vertical measurement, and move my chair a bit closer.
Actually, I'm hoping the
SED sets come out sometime soon. They look promising to me.
