Full HD LCD panel test, light bleeding test, motion test, tv tests.

In this movie you can test the most important things on a TV. Light bleeding, motion video blur, etc. See description below. Adjustments: 0:02 Adjust Brightness and contrast in such way that 245 is barely visible and at the same time you can distinguish different grey levels 0:20 Light should be gradually distributed on the screen from left to right 0:32 On this grey image, a poor quality LCD panel will show light unevently distributed or all kind of artifacts and spots. 0:39 White sometimes may show becklight distribution issues 0:50 A complete black screen cannot be achieved with LCD screens (because they need backlight) However this is to check for uneven light distribution 1:00 Color bars. They have to show the same brightness levels. Grey area from bottom bar should not show any color distorsion 1:10 This may reveal "tricks" used by manufacturers to achieve high contrast ratio. On some screens, backlight light is increased when white is displayed and dimmed when black is shown. This may lead to light variation that can be easily observed in the middle of the screen 1:25 Geometry issues. This was mostly for CRT screens. However, for a relevant test, 0% marking should be visible 1:40 Full RGB vs limited RGB is more complex. Some info can be found here: https://referencehometheater.com/2014... 2:00 The 4 squares with lines shall be visible as parallel lines (depending on the screen resolution) 2:10 Here you should not see weird circles, triangles in any of those 4 moving squares (Horizontal or vertical) However, where motion blur or motion flow (smooth movement engines), are active, the software behind this may generate some artifacts. A motionblur test video here:    • SonyBravia AVC 1080 60i MBAFF motion ...   2:40 The 2 sqared shapes shall appear undistorted on the whole sequence. Same as earlier test. This is not indicating that there is a problem with the TV or screen but extreme motionflow processing may lead to more artifacts here.
