At the Clinton Presidential Library & Museum in Little Rock, AR, 40in LCD displays fed by HD sources depict milestones in the Clinton presidency.
But image resizing is not a simple matter, and in practice the results can vary. At the William J. Clinton Presidential Library & Museum in Little Rock, AR, archive video footage is shown on many different sizes of display — typically 20in, 30in and 40in LCDs. Cortina Productions produced the programs on a resolution-independent production platform with final output at MPEG-2 SD. This looked fine on the smaller displays, but terrible on the 40in. displays, which had nothing to do with the professional production and everything to do with display resizing deficiency.
The solution was to ensure that the display was fed a signal at its native resolution. Because the Clinton Library production was resolution independent, it was a simple matter to output an HD version of the program. This required the use of an HD player, which is now available at very sensible prices. People looking to get the very best out of large flat panel and projected displays should use only HD sources.
