When connects to a DVD source, the display brightness and color seems There are 2 type of explanation: A.
DLP projector has a similar bright/dark spot failure just like a LCD monitor.
It has the advantages of full digitization, high contrast, fine image, small volume, and long-lived life, e The far distance will cause the bigger projection size, and lower image brightness.
It uses four mini-dins to transmit 2 information signals.
These two lines are brightness (luminance, Y) and chrominance. The quality of S-Video is better then composite but not a DLP (Digital Light Processing) is the exclusive technology of the Texas Instruments, adopting the principle of mirror reflection to present images.
Color wheel: The speed of the color wheel is around 6000 rpm. Abnormal spinning noise of the color wheel will be more disturbing and alarm.
Sometimes its e It is a measurement of light that has been standardized by ANSI.
The liquid crystal used in display technology such as LCD/LED monitors, large format display or digital signage is driven by electrodes.
If the same display is remained at the same position for a long time, electric charge driving the electrodes can cause liquid crystal to build up and remain in one position, leaving a mark. This mark or residue as a result of image retention is usually a shadow, or faint outline of the previous static image that was being displayed.
To avoid image retention, please activate the power management function to let the LCD/LED monitor, large format display or digital signage go into "sleep mode", or turn on screensaver after short period of inactivity.
Alternatively, can use animation to avoid same display is remained for a long period of time.
The projectors are made of materials that can bear high temperature, so the heat dissipation fan of projectors usually has burning smell.
