There are a great many downloadable parameter files which imitate popular (and often useful) standard test patterns, from <a href=\"https:\/\/en.wikipedia.org\/wiki\/SMPTE_color_bars\">SMPTE color bars<\/a> (i.e. what you used to see late at night back in the days when TV stations actually signed off) to the legendary <a href=\"https:\/\/en.wikipedia.org\/wiki\/Test_Card_F\">BBC Test Card &#8220;F&#8221;<\/a> (the one with the little girl in the center &#8211; this probably won&#8217;t mean anything to anyone on this side of the Atlantic unless you&#8217;ve watched the original UK version of Life On Mars) and everything in between.  Monochrome, color, you name it.<\/p>\n<p>A lot of what I put into my editing system comes straight off the PC&#8217;s S-video output, which up until recently simply parroted whatever I had on the desktop, icons and all.  A recent update of the driver for my video card finally let me do the &#8220;extend desktop onto the second screen&#8221;, which meant I could compose a &#8220;double-wide&#8221; desktop with something different on the S-video output than the desktop.  Since that output feeds stuff to the Avid on a regular basis, I decided that a good set of pre-calibrated color bars was what needed to be there.<\/p>\n<p>While I&#8217;m gone at work, my wife logs into her user settings on my main PC and uses it to queue up a random playlist of stuff for Evan to watch while she&#8217;s getting dinner ready.  Instead of boring color bars, however, the portion of her desktop that shows up on the TV in my room has a&#8230; shall we say&#8230; <em>slightly modified<\/em> version of the old <a href=\"https:\/\/en.wikipedia.org\/wiki\/Indian_Head_test_card\">&#8220;Indian Head&#8221; test pattern<\/a>.<\/p>\n<p><img decoding=\"async\" src=\"https:\/\/www.thelogbook.com\/earl\/hizzouse\/q4-09\/testpattern.jpg\" alt=\"Evan TV!\" \/><\/p>\n<p>The only problem is that Evan likes his test pattern almost as much as he likes watching anything else on that screen.  \ud83d\ude09<\/p>\n<p>Test Card Maker is neat in that it can render at just about any resolution, but you can also save a parameters file that basically amounts to a very short text file, allowing you to make adjustments later.  I haven&#8217;t really gotten a fix on whether the author of the program is an actual TV engineer or just a test pattern afficionado (there are such things, you know), but it&#8217;s an awfully handy program to have.
