Ragu Z400 Mini LED Projector Review

  1. Great review, Thank you very much! About the „slide show“ option, so if i just want to project one jpg image from a USB jump drive, i could use this projector for that..? Thanks again

    1. Hmm, I don’t have an iPad so I don’t know if there’s a special setting you need to turn on. If it’s not being recognized as a USB drive, then it’s possible the projector doesn’t recognize it as an input source. The only way I know how to get files to play from an iPad to another device is using an Apple TV as the input source and streaming the video to it. I think the Apple TV also lets you mirror the screen to the projector.

  2. Awesome video! I just ordered this on amazon! I have sound bar (a speaker that can be connected via Bluetooth) but do you know if this projector can connect with a speaker via Bluetooth?

    1. The projector doesn’t natively have Bluetooth connectivity. You could try using a battery powered BT transmitter like one of these: http://prourls.co/568b [Amazon Affiliate Product Link] Typically though, these solutions add a bit of a lag so that the audio/video is out of sync by a few milliseconds which may or may not be an issue depending on the severity. The other option is to use an audio cable and connect the headphone/audio out jack to the speaker’s AUX in. That’s usually what I do.

    2. Thanks for your advice! I also wanted to ask about the angle. I’m seeing that if the projector is not facing the wall or a white sheet in a direct angle, the shape of the screen gets strange (not sure how to describe but it’s just not right), have you experienced this and do you know if there is a way to get away from this problem? I don’t have any place in my room that I can set the projector in a direct line, so I’m trying to figure this out..

    3. There is an adjustment wheel but only for vertical tilt (if the projector is leaning back slightly) It’s called the keystone dial and it’s located behind the lens on top of the unit and is the smaller of the two dials (large one is for focus). The keystone can counteract about 15 degrees of tilt. There is no way to adjust the screen for horizontal skew, so if the projector is not perpendicular to your projection surface, one side of the screen will look larger or smaller than it should. The only thing you can do is move the projector to face the wall directly to correct this distortion.

    1. chicken strips
      I have this and am very disappointed after having this for a year now .
      250 will get you a good native 720p projector with more features and 500 will get you a good native 1080p projector with more features .

    1. Hm, does the sound work if an external speaker is plugged in? If so then it’s a problem with the speaker driver, it may have shorted though I do not think it can be easily repaired or replaced. If there’s no sound in the external speaker, the player may be stuck in mute or the volume is set to 0. Also try changing the sound settings in the menu options to see if that makes a difference.

    1. I don’t have a measured value for it, but I gather it’s pretty low as the lag is minimal or non-apparent when using HDMI. On the order of milliseconds.

    1. I forget, but there might be an option for updating via USB in the settings menus. If you can’t find it there, that usually means the projector will automatically detect the software update upon powering up if loaded to the root directory on the USB drive and inserted into USB slot 1. If that doesn’t work for you, I’d reach out to the manufacturer for more details: http://www.raguofficial.com/index.php?route=information/contact

    1. If your Macbook pro can output to HDMI (either it has an HDMI port or you have an adpater) then yes, you can output to this projector via the HDMI input in the back.

    1. In order to display photos in full screen, the resolution of the photo has to be at least 1920 x 1080 pixels or greater and in landscape orientation. Then I believe it should display full screen automatically. If you have portrait orientation photos, it will display them vertically, but of course, it wouldn’t fill the full width of the screen, only the height.

    1. Thanks for the update. Yeah it looks like the product has gone through a few iterations and updates, including the lamp it comes, since I got mine about a year ago with which is nice. I always like when companies continuously improve their products. Makes you feel like they care about getting it right.

    1. Hm, the USB port is used to read files off a device and cannot mirror the screen of a mobile device. If you want to use screen mirroring, there might be a special cable that can convert your charging port to HDMI and you may be able to use the HDMI input on the projector. But this will depend on whether or not your device has this capability (some devices have SlimPort or MHL which allows video output over their data port). Many newer devices are dropping support for wired screen mirroring in favor of wireless screen casting. You’ll have to double check with your mobile device specs or contact the manufacturer for details about your specific device.

    1. You can only do this if the Bluetooth speaker has an AUX input for a wired connection, using a male-to-male audio cable, like this one: http://azon.ly/e8ox [Amazon Affiliate Product Link] This projector does not have wireless Bluetooth capability.

    1. If your phone is compatible, you’ll need to hookup an adapter or cable that can link your phone to the HDMI input, usually done through the charging port (Lighting on iPhone, USB-C or microUSB for Android). However, not all phones have physical display output capability (usually called Slimport or MHL) since this technology is being deprecated in favor of wireless/WiFi streaming. Unfortunately this projector doesn’t support wireless streaming. I’m using an older LG G5 smartphone with a USB-C to HDMI adapter for use with physical input projectors: http://azon.ly/OUTc [Amazon Affiliate Product Link] but again, plenty of current generation phone users are reporting that it’s not compatible with their phones, so you may want to reach out to the vendor to confirm it’ll work before making a purchase.

      The projector I use most often for wireless streaming from my phone is this LED pico DLP projector: http://azon.ly/yvk7 [Amazon Affiliate Product Link] However, it also supports Netflix in its on-board OS, so streaming from a separate device is not expressly necessary.

  3. I was offered one of these as a replacement for my Crenova XPE-400 pico projector which stopped working. I’m glad I didn’t accept.
