Test Card X
The High Definition version of Test Card W is visually similar but officially lacks a designation letter. This version is often referred to as Test Card X, but this is not a designation which the BBC recognises. It is designed for use on High Definition TV services, and has been included a part of BBC HD's preview loop since November 2008 (though has been in use internally at the BBC since several years earlier).

Famous quotes containing the words test and/or card:
“This, then, is the test we must set for ourselves; not to march alone but to march in such a way that others will wish to join us.”
—Hubert H. Humphrey (1911–1978)
“What is the disease which manifests itself in an inability to leave a party—any party at all—until it is all over and the lights are being put out?... I suppose that part of this mania for staying is due to a fear that, if I go, something good will happen and I’ll miss it. Somebody might do card tricks, or shoot somebody else.”
—Robert Benchley (1889–1945)
