Tronsmart Draco H3 Stick Refresh Rate Workaround 50hz ~> 60hz

[xboxhacker]

I recently got my new H3 stick....low and behold it did not work. Unknown to me it was stuck in a 720p50hz HDMI mode. My TV cannot do 50hz. So I had a blank screen/no input.

On tronsmart.com they had a 60hz test IMG. It did work. But netflix did not.

So I unpacked the latest IMG file, and edited the sys_config....repacked it, and now it works 100%!! Netflix seems to be OK!


3 changes needed to be made.
- hdmi-mode = 5
- screen0_output_mode = 5
- screen1_output_mode = 5

5 is the 720p60 mode

repacked it, flashed it....now working! It defaults to 60hz everytime after a power cycle!


This is the sys_config

EVEN BETTER!

You can use DragonFace v2.2 to open and edit the IMG files for the H3 Stick!

It will tell you its not compatible, just click OK.

Goto Advanced Settings>>system configuration. This will open the sys_config. Edit it and save it. Then Save the new IMG.

FYI: it takes a long time to load and save the IMG files in DragonFace.
