General info

1.lamp life

15000h

3500h

This shows the lifespan of the light source. Projectors need to have their lamps (light source) replaced every now and then.
2.audible noise

Unknown. Help us by suggesting a value. (Optoma UHD51A)

33dB

Audible noise is the noise that a device produces while in operation. Reduced audible noise improves quality.
3.has laser light source
Optoma UHD51A
ViewSonic PJD6383S
Laser projectors have a much longer lamp life compared to traditional bulb projectors. The brightness and color reproduction also stays the same, whereas the brightness of bulb projectors can slowly degrade over time.
4.audible noise (eco)

Unknown. Help us by suggesting a value. (Optoma UHD51A)

Unknown. Help us by suggesting a value. (ViewSonic PJD6383S)

Audible noise is the noise that a device produces while in use. Some devices have an eco mode for quieter operation.
5.operating power consumption

Unknown. Help us by suggesting a value. (ViewSonic PJD6383S)

The device's battery life (when in use) as given by the manufacturer. With a longer battery life you have to charge the device less often.
7.lamp life (eco mode)

Unknown. Help us by suggesting a value. (Optoma UHD51A)

Unknown. Help us by suggesting a value. (ViewSonic PJD6383S)

This is the lifespan of the light source when using the projector in eco mode.
8.power consumption in standby mode

Unknown. Help us by suggesting a value. (Optoma UHD51A)

1W

The power consumption in standby mode, also called energy-saving mode, measures the amount of power the device consumes when shut down but still plugged in.
9.thickness

280mm

242mm

We consider a thinner chassis better because it makes the product more compact and portable. Thinness is a feature highlighted by many manufacturers of mobile devices, but it is essential for a wide range of products.

Projection quality

1.ANSI lumens

2400lumens

3000lumens

The light projected by the device is brighter, i.e. it has a higher ANSI lumens measurement.
2.resolution

Unknown. Help us by suggesting a value. (Optoma UHD51A)

1024 x 728px

Resolution is an essential indicator of a screen's image quality, representing the maximum amount of pixels that can be shown on the screen. The resolution is given as a compound value, comprised of horizontal and vertical pixels.
3.contrast ratio

500000:1

Unknown. Help us by suggesting a value. (ViewSonic PJD6383S)

Contrast ratio is the visual distance between the lightest and the darkest colors that may be reproduced on the display. A high contrast ratio is desired, resulting in richer dark colors and more distinctive color gradation.
4.has motorized focus
Optoma UHD51A
ViewSonic PJD6383S
You can control the focus remotely, ensuring that the image stays crisp and clear.
5.displays 3D with glasses
Optoma UHD51A
ViewSonic PJD6383S
It supports displaying 3D images from devices such as a 3D-compatible Blu-ray player, allowing you to watch films in 3D when using suitable glasses.
6.maximum projection size

Unknown. Help us by suggesting a value. (Optoma UHD51A)

300"

The maximum size of image that a device can project without compromising quality.
7.has motorized zoom
Optoma UHD51A
ViewSonic PJD6383S
Motorized or power zoom lenses allow the user to remotely press a switch, for example on a remote control, causing the projector to automatically zoom in or out and correct the size of the image.
8.zoom ratio

1.3:1

Unknown. Help us by suggesting a value. (ViewSonic PJD6383S)

A projector zoom allows you to increase or decrease the size of the projected image without moving the projector. The most common zoom ratio among today's projectors is 1.2, which means you can vary the image size by 20% by simply adjusting the zoom lens.
9.has a display enabled for HDR10+
Optoma UHD51A
ViewSonic PJD6383S
The display supports HDR10+, which is an improved version of HDR10 video technology. HDR10+ uses dynamic metadata so that each frame can have its own settings for contrast, brightness, and colors, which results in lifelike images.

Features

1.has lens shift (vertical)
Optoma UHD51A
ViewSonic PJD6383S
If the projector is not perpendicular to the projection surface, it will distort the image. Vertical lens shift allows you to correct this distortion so that you can place the projector below or above the projected image (e.g. mounting the projector to the ceiling).
2.has lens shift (horizontal)
