Pattern test
The thickness of the line pattern is as follows.
7px | 4px | 2px 1px
When viewed through the camera, most products display the fourth square (1px) as a grey blur rather than a line
The 1px Dot pattern allows to test for
correct camera coverage.
Many products will display grey blur
rather than dot pattern.
Colour Gradient Test
Gradient test is important and is like grayscale test
From black to RGBW and from RGBW to White
RGBW : Red Green Blue White
Screen Gradient Test
Gradient test is important and is like grayscale test
Gradient IN
Gradient OUT
Gradient Rec 709
- Inconsistent Gamma Grayscale Possible
- Module White or Black Grid Problem ( Calibration can also cause )
Fast Motion Test
This is caused when an actor moves in front of the screen on the actual Virtual Production environment. Many products have unnatural motion blur or noise around people.
Noise Around Person
Screen Blur
Genlock Sync
Genlock synchronises the cameras. It uses the pulse that generates the frames within the camera as the synchronisation point. Controlling System: Colorlight, Novastar and Brompton support Genlock
Moiré
Moiré happens because your LED panels are made up of a tight grid of individual LED pixels. The sensor that captures the image in a digital camera also works on a grid system, using an array of millions of tiny light cavities, or “photosites”. They will never be in perfect alignment with each other and the clash of the two causes moiré.

Latency
- Driving Chip lose 1 frame on 60Hz = 0.167seconds
- Receiver lose 1 frame on 60Hz = 0.167seconds
- Total of 2 frames on 60Hz = 0.334 seconds
- By adding processing and correct module design can improve the low latency
60Hz = 0.167s –
0.334s
Change of 60Hz to 120Hz will reduce the latency time
by half
60Hz = 0.167s – 0.334s

Brightness Test
Higher Brightness will improve HDR Effect
HDR+ Standard requires the display to achieve 3000 cd/m2
Brightness will increase explosion, car lighting effect and much more
Other Benefit: lower consumption, better white uniformity range, Longer Lifetime

Refresh Rate
- 1920Hz is the minimum for most of the camera.
- 3840Hz is standard for most XR solutions available.
- DVX Studio is 7860Hz
>= 3840Hz
FPS - Frame Rate
- Standard 60Hz
- Market requirement 60Hz – 240Hz
- Increased frame rate can improve the latency.
- From 60Hz to 120Hz = 2X , Receiver = 2X, Processor = 2X
- From 60Hz to 240Hz = 4X , Receiver = 4X, Processor = 4X
60Hz – 240Hz
