Introduction
The Acer P8800 equipped with four legs unscrewed from the case (approximately 28 mm, a steel stand and a threaded steel sleeve, rounded soles made of rubber), which eliminate a slight skew when placing the projector on a horizontal surface. For fastening to the ceiling bracket, 4 steel bushings with M8 thread embedded in the bottom of the Acer P8800. Two more pairs of threaded holes intended for mounting optional accessories – an anamorphic external lens attachment or filter.
Appearance
The design is rigorous. It would suit a high-end home theater projector. The external panels of the Acer P8800 made of plastic with a black matte finish. The lens niche made of aluminum alloy with a matte silver finish. The lens hood, like its body, is also metal. The layout is symmetrical – the axis of the lens aligned with the longitudinal axis of the projector body – which is aesthetically pleasing and somewhat facilitates the installation of the projector.
The control buttons are located on the right side closer to the rear, and removable ventilation grills situated closer to the front, behind which the user can place the optional air filters. At the junction of the support and the right side, there is a steel pin in a niche, for which the projector can fasten to something massive, so as not to be stolen. Nearby is a connector for Kensington Castle. The lens equipped with electromechanical focusing and zoom drives. Two knobs on the front panel allow the user to shift the boundaries of the projection. So that the picture changed by a maximum of 80% of the projection height up and down vertically and 35% of the projection width to the right and left horizontally (according to the manufacturer). To facilitate projection adjustment, test patterns can display from the menu.
Menu & Localization
The type of projection selected in the menu (front / translucent, conventional / ceiling mount). The Acer P8800 projector is medium-focus, and at the maximum focal length of the lens, it is rather long-focus. Therefore, in frontal projection, it is better to place it approximately on the line of the first row of viewers or behind it. The menu is strict. It has mainly black and white design. The font of the menu is small, so the readability is low. There are a lot of settings. Navigation is convenient, but it’s a little tricky because, on the remote control, there is an F3 button between the Menu button and the block of cursor buttons. The bottom line of the menu 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 – only the name of the setting, the slider, and the current value – which facilitates the assessment of the changes made to the image.
Modes & Effects
There are six modes of geometric transformation. The first four are enough to display pictures with a typical or original aspect ratio on a 16: 9 screen. Of these, the LBX variant also designed to perform the necessary transformation using the optional anamorphic nozzle (lens). One mode is point-to-point output in the center of the projection area, and the last mode involves the automatic selection of the transformation. A separate setting affects the cropping of the edges, without enlarging the picture. There is a digital enlargement of the central part without shifting the enlargement area and digital image shift, while within a few pixels, the picture moved without cropping.
Sound Characteristics & Power Consumption
In standby mode, the power consumption was 1.9 W (network interface enabled). In terms of use in the office or a large room, the Acer P8800 projector is a quiet device. The noise from the cooling system is even and not annoying. The function of the increase in resolution (XPR) is accompanied by some sound that can be heard on the background of noise from the cooling system, especially when the projector is at low power. When outputting built-in test patterns, this function is disabled, so the projector is a little quieter.
Connection & Communication
The Acer P8800 projector equipped with three HDMI inputs, a DisplayPort input, which is a rarity for projectors, and the only analog video input, is VGA (with component signal support). HDMI inputs are not equal, only HDMI 2 has version 2.0 and supports HDCP 2.2. From a practical view, it helps not just a 4K video signal, but also with the highest possible color clarity at a frequency of 60 frames / s. Switching between sources is carried out using the Source button on the Acer P8800 projector cabinet or on the remote control (in this case, a list of inputs displayed on the screen in which the desired data selected) or the direct selection buttons on the screen remote control. There is a disconnectable function to automatically search for an active input with a limited number of input search cycles.
The USB Type-A connector is used for service purposes and to external power devices, such as Wi-Fi adapters connected to HDMI. For remote monitoring and control, the user can use the RS-232C interfaces (on the CD-ROM, there is a table with commands) and Ethernet. Declared support for Crestron (monitoring), there is also a built-in projector web server with a virtual control panel. With this method of connecting to the HDMI 2 port and DisplayPort, 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 (i.e., without color resolution reduction) with a depth of 8 bits per color. The white field looks evenly lit; there are no color stains. The uniformity of the black sphere is excellent, only in the central part it is slightly lighter, there is no glare on it. The geometry is almost perfect. The clarity is very high. There are practically no chromatic aberrations. Focus uniformity is excellent.In this 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. In the case of progressive signals, the picture is obvious, and in the case of interlaced color, clarity is slightly lower than possible for this type of signal. The colors are correct, weak gradations of shades in the shadows, and the light areas of the image are well distinguished. Overscan is disconnected. In the case of 1080p at 24 frames / s, frames are output in an alternating 2: 3 duration.
