Picture quality of internal content appears darker than HDMI or USB-C

Solution

Upgrade to the latest software version. Version 1.0.27 fixes this.

No further tweaks are necessary.

Historical information

This was a bug with the color adjustment of the internal software system's output. On versions prior to 1.0.27, the brightness and contrast were not set correctly. If you are on v1.0.26 or lower, you may follow the below instructions to apply the tweak.

It is not necessary to apply this tweak if you have updated the PicoPix Max software to v1.0.27 or higher.

Quick instructions

• Go to Projector Settings > About > Software Version and press [OK] 5 times quickly.
• From the menu that opens on the right side, go to Device Preferences > Display > HDMI > Advanced Settings.

• A screen as below will open up:

  

   

• Click on RESET first, then increase the Brightness and decrease Contrast settings as follows, so that they’re approximately in the position you see in the screenshot:

Brightness should be a bit after the left edge of the RESET button.
Contrast should be a bit before the “C” of CANCEL.

This will match the internal content picture quality to external/HDMI colours. You can experiment with the Saturation knob if you want.

Background

Due to a bug in the default Color Adjustment settings screen, the correct brightness/contrast parameters are not adjusted. This hidden screen lets you adjust the correct parameters which actually affects the colors.

In the next software update, we will correct it so that the above adjustments are the default. Till then you can make this manual adjustment.

How to verify that it worked?

Open Firefox on the projector and go to http://www.lagom.nl/lcd-test/black.php 58
