The HDMI feed from a HD device will give High Definition video quality up to 1080i. With a flat, light coloured wall the images are clear and watchable without having to also acquire a projector screen. Probably not in an office but in a living room or more realistically a bedroom as a replacement for a flat panel TV. However, in a normally lit office environment the image was also difficult to see clearly unless you beamed the image onto a screen close to the projector but this defeats the object and you may as well use a normal laptop screen or 19-21” TFT monitor.Ĭonnecting the Acer c20 to a Freeview Recorder using a HDMI cable and mini-to-standard HDMI convertor (not included but not expensive) and dimming the room light levels and the c20 appears to have found a possible use. I later found that better results were achievable if your laptop has an HDMI output in addition to the standard VGA output. However I found that the connector to connect to a SmartPhone was an optional extra and when connected to a laptop the native resolution was less than the standard laptop screen so although the effective screen size was larger, the amount you could get on was less. My initial idea was that it would be good to carry in place of a larger projector when doing small venue presentations, demonstrations or training.
It comes with a charger and several cables/adapters to connect to various devices such as your laptop. It has a built-in battery so you can, in theory, use it without mains power. The Acer c20 Pico Projector is about the same size as a modern SmartPhone but slighter thicker.
