Let's not forget a couple of things here ;
First , is that we had magnifiers that stood on the table right in front of the picture tube that made the image quite a bit larger and thus viewable from somewhat further away .
Second , we were not expecting 1080DPI HDMI quality , we were just darned happy to have moving pictures to go along with the radio . In some cases , this lack of clarity was actually a good thing in that every Zit , Mole , or Wart wasn't there in scarily clear well rendered colors ......
