Just to say, with mainline Linux starting from 4.18, you can have almost any VGA and DVI resolutions supported directly without any hacks or tweaks

Any body has managed to get the 2560x1440 resolution to work on VIM2? Thanks
Hi omegasystem, did you manage to recompile the kernel to work with the resolution?
What is the status about this issue?
I have tried all the patches in this thread on VIM1 based on your V171028 Nougat firmware. 1920Ă1200 is not displayed properly on the iiyama ProLite E2403WS. Also, there is sometimes an unexpected resolution after boot:

Do you plan to integrate these changes into your official firmware and to fix the remaining issues, including those reported by @davemf? Thanks.
Reading all this got me confused. What is the situation now?
Does this work with VIM1 Android 6 ? it is USB + HDMI
7" Inch Capacitive Touch Screen LCD Display 1024x600 HDMI for Raspberry Pi 2
Hi, did you find any solution?
I have an 5.5" lcd with 2560x1440 resolution.
Please reply
thank you.
Hi!
Do you have any solutions about problems that wrote DaveMF:
unexpected resolution after cold start or reboot VIM1 and âgreen screenâ at times after reboot?
Itâs actual for me, but during half a year I donât see solution.
Thanks
No, sorry, i gave up on this. could not figure out how to change the coding. Those guys from khadas should really invest on this. It is such a strong hardware, but if it is only for used as a TV stick, such a waste

Hello. Is there any hope that the error will be fixed? The topic was launched in May 2017. Today is September 27, 2019. You made a wonderful piece of hardware with great potential for the future, but without normal technical support for software, this is just a piece of hardware. It is foolishly hoping that enthusiasts will finish everything themselves and figure it out. You sold the assembly kit, then the buyer will do everything himself and figure it out himself. With this attitude, your product will never become popular. Why buy a new VIM3 if there will be the same attitude towards the buyer? In terms of iron, your product is undoubtedly better than competitors, but with the support, alas, everything is very bad.
Android 800x480
My experience so far with VIM3L:
Android: I connected directly to a 1366768 monitor but antutu declared 19201080, this wasnât too bad tough as the image displayed on the screen is perfect.
Then i flashed Ubuntu 18.04 on the emmc, same monitor, GUI looks really small and declared resolution on hardinfo (a system analizer - sudo apt install hardinfo) is of 1920* 1080, no options to change the resolution down. I need 1366 * 768 or at least 1280 * 720 is there a way for my board?
You need to verify the path
**PLATFORM_VERSION=6.0.1**
**TARGET_PRODUCT=full**
**TARGET_BUILD_VARIANT=eng**
**TARGET_BUILD_TYPE=release**
**TARGET_BUILD_APPS=**
**TARGET_ARCH=arm**
**TARGET_ARCH_VARIANT=armv7-a**
**TARGET_CPU_VARIANT=generic**
You need to refer to
I am able to update the ROM with the 800x480 resolution, but it is still not showing anything in my LCD. Any suggestion would be really apreciated.
LCD Driver Module>> Adafruit TFP401 decoder 800x480 EDID
Android Version >> Marsmallow 6
Thanks before.
e still donât support the VESA resolution on official source code. You need to review the topic again.
Thansk!
How can I add support for the 1280x480 screen resolution for this monitor (LQ123K1LG03 ) in Ubuntu Linux on Vim3?
Recently, I was doing an HDMI interface test with a display resolution of 2560720, and found a strange problem. The test in UBOOT showed that if it is a picture of 1280720, setting FB_WIDTH 1280 FB_HEIGHT 720 will display the full 2560720 picture effect through zooming, but setting FB_WIDTH 2560 FB_HEIGHT 720 When displaying the resolution of 2560720, the part of the picture will be automatically truncated. The following is the display effect of the picture I intercepted;
ShĂ ng tĂș shĂŹ 2560720 de tĂșpiĂ n xiÇnshĂŹ xiĂ oguÇ, bÄnlĂĄi yÄ«nggÄi shĂŹ zĂ i tĂșpiĂ n yĂČubiÄn de zĂŹ xiÇnshĂŹ zĂ i zuÇbiÄnle, zhĆngjiÄn duĆle tiĂĄo hÄi biÄn
44/5000
The above picture is the picture display effect of 2560*720. The word on the right of the picture should be displayed on the left, and there is a black border in the middle.
The picture above is the picture display effect of 1280720, which is enlarged and displayed as 2560*720 picture through OSD.
What caused this? Does the A311D display have a limited source aspect ratio?
Whatâs the system of your device? Ubuntu or Android?
