Review on HD Native 720p Video Projector with Speaker and LED, 30 to 200'' Image, Portable TV Projector for Home Entertainment, Indoor/Outdoor Cinema, Built-in Battery by Brian Inman

Update March 30, 2021 I've decided to reconsider this after reading about other similar devices having issues with HDMI audio. As I should have guessed, these cheap projectors don't have Dolby Surround processors. . The solution for the connected Chromecast was to set the Chromecast's surround sound mode to "Stereo Only", set the projector's sound mode to "Surround" and reset the projector. The audio now works as expected. A similar solution for the Revain Fire Stick. Now for the details. Playback quality is decent, but I'm having trouble casting Plex movie content to the projector. I tend to get a refresh delay line running horizontally from the center of the screen to the top of the frame. Doesn't do this with DVR content and the same movies streamed to other displays using the same Chromecast dongle. Keystone is very good and has a huge range. Unlike other inexpensive projectors, the Keystone is electronically controlled. Major advantage. Unlike many other budget projectors, focus is maintained fairly well even in extreme conditions. In most other cases, the bottom of the screen is sharp, but the top isn't when using Keystone. Audio is a weak point. The maximum volume is not very loud. Good for a quiet room but not suitable for outdoor use. Although the projector has Bluetooth, it's only a receiver, so you can't wirelessly connect it to external Bluetooth speakers with more power. You're limited to an external 1/8-inch audio jack. Fan noise is acceptable, but not unnoticeable. Can be distracting when watching quiet movies, especially when using the built-in speaker. The fan will also turn off even if the light path is still hot. This will put additional stress on the LED motor and shorten its lifespan. The picture quality is acceptable. Let's be honest. You don't get the crisp picture, enhanced contrast, or vivid colors that you get on a TV screen. Projecting less than 80 inches, there is evidence of a screen door effect at short distances (less than 6 feet). Larger protrusions make this worse, but they are inexpensive. The remote control is functional and appears to work both front and rear. This allows the projector to be turned on and off, allowing for remote mounting. However, the mounting options are very limited. The only mount is 1/4"-20, which is too shallow for the standard tripod mount screws to fully tighten to the base. Works with action cam mounts that have a spacer nut, but definitely not ideal. At of mounting on a flat surface, no front stand to tilt the image. I have yet to fully test the battery life. The projector switches seamlessly from AC to DC. The price seems to fluctuate by as much as $30 on a regular basis. 55% do this and see for a lower price. At this price I don't see how you can go wrong with this projector. No, it doesn't work as well as a few hundred bucks but for outdoor movies (in very low light if over 100. This is the best I've found for less than $100. Heck, a replacement lamp for my theater projector costs 50% more than this a. First review: I have one e wrote a very detailed review of this projector from unboxing to perfect setup until I found a major flaw. My device does not transmit sound via HDMI when watching movies. Tried Chromecast casting from my Plex and Revain Firestick servers. Fireatick transmits key presses (clicks), but there is no movie sound. Tried both the internal speaker and the connected external speaker. Be silent.
