if you have another HDMI in your tv try it, I change to another one, and it is feet the screen.
It has been more than 3 months, but the top product of khadas remains without full functionality. This is a big disappointment for users who changed the VIM1 to VIM2.
I am not satisfied with vim support for now, there are still bugs in Android, Linux is missing proper driver support, but things have improved, they are now much better than before.
If i have known all of this when i bought it, i wouldn’t have bought this board, but i am really hoping for proper Linux support with all the drivers needed, but i am afraid that we will need to wait a long time for it to come, if it ever comes.
I know it’s not only their fault, a lot of job is needed from Amlogic and Arm too, problem is that these two companies only support Android, there is no Linux support from them.
I am now using Android Nougat latest image, Nougat images before had a serious bug with systemui stopping, for the first time i can use this board to watch movies and other stuff, it was impossible to use it with previous images.

The VIM2 Vesa resolution patch is the same with VIM. In addition, you need to modify the kernel driver

Yes, I applied аll VESA patches. But if you do not disable the UI interface scaling, the image begins to twitch strongly.

SORRY, this is google translate…
You can download my ROM.
The resolutions are displayed in a full list regardless of the display.
“640x480p60hz”, “800x480p60hz”, “800x600p60hz”, “1024x600p60hz”, “1024x768p60hz”, “1280x800p60hz”, “1280x1024p60hz”, “1360x768p60hz”, “1366x768p60hz”, “1440x900p60hz”, “1600x900p60hz”, “1600x1200p60hz”, “1920x1200p60hz”.
List scroll down is possible with the keyboard only, mouse or touchscreen does not scroll through the list, be careful!
Аlso you can evaluate the hidden menu of the user interface editor in System UI Tuner (navigation Bar), which allows you to edit the navigation bar (NavBar) directly from the system. Basically, this menu is always hidden, but it happens that on some devices added from the factory. To activate the hidden menu, press and hold the gear in the shutter status bar, it will start to rotate quickly, after 5 seconds, release the gear and get into the menu More settings-system UI Tuner. In the status Bar submenu, you can turn off/on icons such as battery power or make a clock with seconds.
I modified the functionality of the system UI Tuner menu “navigation Bar”, I added keys: volume+ (vol up), volume - (voldown), turn off the sound (mute), previous song (prev), next song (next), music start/pause (play). Someone may object and say that using the “key Code” you can add any button and the picture on it, and why I added your button. So here is I answer: Yes, can be add, on the field 1-2-3 reboots, the button disappear and-button will become invisible. Although such a bug can be used to create a hidden button, it is enough to know its location and it will work. My buttons are considered system buttons and always work. We strongly recommend to modify navbar only when the screen resolution is 1920*1080, otherwise due to the peculiarities of the scale at other resolutions, the interface of the modifier is not removed from the screen, and the flipping function it does not support.

Hi, terry!
I build ROM with VESA resolutions for VIM1 and VIM2.
It work perfect. But it have some bug on 800x480 resolutions for VIM2 only (VIM1 has not this bug).
After first reboot, picture is well
But after second reboot:
third reboot:
fourth reboot again nice:
How to fix this bug on VIM2?
Can you provide some informations for me?

Please tell:
Does ABD not work if I use:

Hello!
I tested DaveMF firmware for VIM2 with HSD080IFW1 1024x600. When the screen resolution is 1920x1080 everything is fine, I switch to 1024x600 then reboot and the green screen appears, sometimes when the screen resolution changes the image distorts, only the firmware of the device helped. Tried 1280x800 also works fine, changed to 1024x768, again skewed and a green screen. On the home TV the same as on HSD080IFW1.
Here’s the video youtu.be/-1hD8AsEZtU

Hello! I’m testing DaveMF firmware too.
On this firmware, after ~20 minutes, if I click on “home” or “multitasking” virtual button -
all the sound in the system disappears.
It only helps reboot the console.
In previous firmware - everything is ok.
I’m use hdmi is sound output.
Resolution is 720p60.
This my dmesg log -> https://yadi.sk/i/MCR7rka73TkR9N
