The external panels of the Acer V7850BD projector made of white plastic with a matte or mirror-smooth surface. The niche of the lens and the outer lens housing made of plastic with a matte silver-gold coating. A decorative aluminum alloy ring glued to the end of the lens niche. In general, the case is non-marking. On the top panel, there is a niche for accessing the zoom lever on the lens, the lens shift knob, and the control panel with a round tinted IR receiver window, buttons, and status indicators.

A sheet of durable plastic glued onto the vertical plane of this niche – the connectors’ metal edges do not leave visible scratches on it. Signatures to connectors are more or less readable. The user can also find the power connector and the connector for the Kensington lock on the rear panel. At the junction of the bottom and left side, there is a niche with a jumper made of plastic. For which the projector can fasten to something massive, so as not to be stolen—the ventilation intake grill located on the left side. There, closer to the front, is the grille of one of the two speakers. There is no dust filter in the Acer V7850BD projector, which is typical of modern DLP projectors.


Menu & Localization

The menu is strict, and it has a predominantly black-gray-yellow design. The font of the menu is small, and it is too dense, but the inscriptions are contrasting, gray. As a result, the readability of the menu is acceptable. There are a lot of settings. Navigation is quite convenient, the transition from point to point is slightly slowed down, but the lists are looped, which speeds up navigation. The bottom line contains a hint for the functions of the buttons. When setting some parameters that affect the image, a minimum of the information displayed on the screen, for example, only the name of the setting, the slider, and the current value, which facilitates the assessment of the changes made to the picture.


VGA Connection

With a VGA connection, a resolution of 1920 by 1080 pixels at 60 Hz frame rate supported. The clarity of the picture is excellent, but its interpolation is a little underestimated. The result of automatic adjustment to the parameters of the VGA signal does not need manual correction.


Remote Controller

The body of the IR remote control is made of plastic with a matte finish on the outside. The upper part of the remote control is white. The lower part is light gray. The remote control is small. It fits comfortably in your hand. The user can reach all the buttons without intercepting the remote control in your hand. Badges are not very small (they are from rubber-like material), signatures to them, too.

The button travel is not long; a pronounced click heard when the buttons are triggered. There is a reasonably bright LED backlight that turns on when the user press only the backlight button, which is inconvenient, moreover, this button does not phosphoresce in the dark, as it happens. The backlight turns off 10 seconds after the last button on the remote control or when the user press the backlight button.


Projection Control

The image focused on the screen by rotating the ribbed ring on the lens, and the lever adjusts the focal length. Jumping when the user press the knob on the top panel allows the user to shift the boundaries of the projection. So that the picture moves up to 15% of the projection height up. In practice, measurements showed that the range is even more extensive, about 17%: the bottom of the projection can be either slightly below the axis of the lens (2% of the projection height) or slightly higher (15%). To facilitate the projection setup, a test pattern can display from the menu.


Sound Characteristics & Power Consumption

The built-in speakers for the Acer V7850BD are very loud. Distortions and spurious resonances are well pronounced; there are no low frequencies. There is a stereo effect, but the left channel sounds louder. However, in general, the quality is higher than is usually the case with speakers built into the projector. When headphones are connected, the built-in speakers turn off. The volume margin when using 32 Ohm headphones with a sensitivity of 112 dB is vast. The frequency range is extensive; background noise is lower than audible; the sound quality is excellent.



With this method of connecting to the HDMI 2 port and in the case of a suitable video card, the model is supported up to 3840 by 2160 pixels and 60 Hz frame frequency with 4: 4: 4 color encoding (that is, without reduction color resolution) with a depth of 10 bits per color. The white field looks a little lighter in the center than in the corners. There are no color stains. The uniformity of the black area is excellent (it is also slightly lighter in the center), there is no glare on it. The clarity is high. There are practically no chromatic aberrations. Focus uniformity is excellent.

In the household case, the HDMI connection tested when connected to a Sony BDP-S300 Blu-ray player. Supported modes are 480i, 480p, 576i, 576p, 720p, 1080i and 1080p @ 24/50/60 Hz. The picture is apparent, the colors are correct, weak gradations of shades in the shadows, and the bright areas of the image are well distinguished. Overscan for HD modes turned off. In the case of a 1080p signal at 24 frames / s, frames are output with an alternating duration of 2: 3. The brightness clarity is always high and is determined only by the type of video signal, and the color clarity for interlaced signals is slightly lower than possible. The Acer V7850BD projector equipped with two HDMI inputs and a single analog video input – VGA. HDMI inputs are not equal, HDMI 2 has version 2.0 and supports HDCP 2.2. From a practical point of view, this means that it helps not just a 4K video signal, but also with the highest possible color clarity at a frequency of 60 frames / s. Also, it is this input that supports the connection of mobile devices via MHL. Component color-difference sources can also connect to the VGA input, but for this, the user will need to use an adapter for three RCA sockets, purchased separately.
