Hello dear friends on the web! I have discovered the wonderful secret to making these thin screens go just as fast as my old Zenith television. My grandson told me the picture travels inside the black cord like rays of sunshine, so I wrapped the whole wire in aluminum foil from the kitchen. It keeps the electricity from leaking into the air! Now my computer cursor moves before I even think about touching the rollerball! What a delightful little trick for us all. Blessings!
