We are working for more HDMI output resolutions supporting, but we need monitors for the testing. So if you happen to own a thus monitor and willing the assistant us for the testing, please download this rom and have a test.
HDMI Vesa resolution list
Please give me some feedback on your tests.
Thanks very much!
I check resolutions. Yes, I can see many VESA resolutions.
As you said early in this topic, this resolutions are not native. Displays see right resolutions, but UI still works on 1920*1080.
Good work! It remains to make native display resolutions
Maybe, need to show full resolution list always, not support resolutions only.
Where did you find this information? I was using it with Raspberry 3B+ at 1024x600 at 60Hz - even configuration says about: hdmi_cvt 1024 600 60 6 0 0 0.
It was also working properly at 1024x600 at 60Hz with Khadas VIM3 with Ubuntu 4.9 (SD/USB version only) and Ubuntu 5.8. Also after connecting to my laptop it NVIDIA driver says it is 1024x600 at 60Hz.
And last thing as mentioned before - 720p 60Hz runs ok even with earlier Android images - the only thing is that image doesn’t fit the screen
Display controller is TI TFP401APZP (up to 1080p at 60Hz).
Are you sure you don’t have a fake one? There are a lot of them on the market and there are some problems with fake one?
Just to be clear…
This LCD which I have:
It is WORKING with Raspberry at 1024x600 60Hz
It is WORKING with Khadas VIM3 with Ubuntu with kernel 4.9 (SD/USB only) and Ubuntu with kernel 5.8
It is WORKING with only Uboot mainline
It is WORKING with Laptop with Windows 10 and NVIDIA graphics card
It is NOT WORKING with Khadas VIM3 with Android 9 Pie…
It is NOT WORKING with Uboot 2015
Systems from points 1 to 4 says it is 1024x600p60hz.
And YES it is the same LCD. It is even lying in almost the same place on the desk
Photo and video proofs for point 4:
And YES - I’ve checked multiple power supplies, multiple images, multiple HDMI cables, USB cables. Still ONLY Khadas VIM3 with Android 9 Pie is not working.
I’ve even make a long-shot try and coppied Odroid N2 Uboot 2015 drivers (hdmitx, vout, vpu, osd, edid_parsing) to Khadas Uboot 2015 and it shows something - by manipulating with HDMITX, OSD and UI commands I can draw rectangle and write a text and it seems to be ok.
Do I really have to bring photos and videos from RPI and VIM3 with Ubuntu or can you just believe that it is a problem ONLY with VIM3 Android?
Moreover I even don’t know it is really still a problem… Mainly, with this new image, Android doesn’t recognize LCD due to some EDID problems, so it doesn’t set resolution.
So it is why I’ve asked is there a possibility to force resolution on Android through serial console or adb?
This isn’t mine, it is another person’s display…
I am not sure it is verified original or not,
Oh, yeah just forgot you are asking about Android and not Linux, sry…
legacy kernel is a real pain, I just learned about it yesterday…
it is not only just resolution problem, but also screen rotation, as we have been facing it in linux 4.9 (not related to HDMI, but it shows the problems related to the BSP)
