General info

1.lamp life

3500h

15000h

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

31dB

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

Audible noise is the noise that a device produces while in operation. Reduced audible noise improves quality.
3.has laser light source
Epson EH-TW9400W
Optoma UHD51A
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)

20dB

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

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

355W

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

How much power the device consumes when it's switched on.
6.Battery life

Unknown. Help us by suggesting a value. (Epson EH-TW9400W)

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

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)

5000h

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

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

0.35W

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

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

450mm

280mm

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

2600lumens

2400lumens

The light projected by the device is brighter, i.e. it has a higher ANSI lumens measurement.
The resolution represents the amount of pixels that make up the image. It is a key indicator of image quality, with higher resolutions providing sharper and more detailed images.
3.resolution

Unknown. Help us by suggesting a value. (Epson EH-TW9400W)

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

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.
4.contrast ratio

1200000:1

500000:1

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.
5.has motorized focus
Epson EH-TW9400W
Optoma UHD51A
You can control the focus remotely, ensuring that the image stays crisp and clear.
6.displays 3D with glasses

7.maximum projection size

300"

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

The maximum size of image that a device can project without compromising quality.
8.has motorized zoom
Epson EH-TW9400W
Optoma UHD51A
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.
9.zoom ratio

2.1:1

1.3:1

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.
