MAX 8K OS

Dune HD has been using the same base OS for at least a decade now and well if it isn’t broken don't fix it.

Initial tab lists several available movies both from streaming services and available in your local collection (same goes with the TV series tab - for some reason Dune HD removed the screenshot feature so I had to use my camera for this).

Since I don't use the Dune HD to watch TV online next tab is the apps one from where you can see all installed ones, both Android and Dune HD (and add more).

The settings/setup tab is the one I always care about most and so from here you can adjust pretty much everything.

The general tab allows you to change language, time zone, time format, and enable the screensaver function.

From the video tab you can change the resolution (up to 8K60), adjust framerate, enable auto resolution, use picture quality options (you'll need to test these to find the best result for your TV/Projector), adjust the HDR and DV settings (my Samsung 65" OLED uses HDR10+ so I had to change some of these), use additional video settings (color space related) and access the HDMI CEC android tab.

Inside the audio tab you have options like digital output (original bitstream or PCM), sampling rate, HDMI and S/PDIF audio out and of course the Hi-Fi audio out.

You can also install and run more apps from the setup tab as seen above.

Dune HD allows the end user to switch between the old and new OS styles and change some of their properties.

Language, subtitles, TV controls, and photo and Blu-Ray functions can also be adjusted from here.

Miscellaneous options related to the remote control, file browsing, synchronization between devices, encodings, location, parental controls, LED display, power, wake-on-lan, firmware updates plugins and more are available from this tab.

For this review I used the latest available update (250919_1551_r24).

Since the Dune HD OS is based on Android 11 you can also access its settings regarding video, audio, screensaver and connected devices.

The information page lists the model name, serial number, license, IP/MAC address, connectivity type and time.
