Here is a video of the tearing and the extra dots appearing on the display. The display is rotated for now until I fix the Android build to rotate to landscape.https://youtu.be/NmyMciQCH5II made so...

I have the display working with the settings I posted earlier except that there is some tearing on the edges of text and graphics. Very slight but noticable and I am sure it should be rock solid as...

As you sell a 7" cape for the Beagle Bone, do you have the kernel configuration for this display?I am trying to get a NHD-7.0-800480EF-ASXN#-CTP to work with an Android build. Using the following t...

Thanks, Mike,I am running with a Samsung S5P6818 8 core A53 processor board from FriendlyArm (NanoPC T3 Plus)I'll try lowering the pixel clock too. Right now it is at 30Mhz. I have the drive level ...

I was able to add 22R resistors to the CLK, HSYNC, VSYNC and DEN and reduced the drive current on the RGB lines and now I seem to have a more stable display although I do see some horizontal shift ...

Thanks MikeI suspect I have reflection issues as I didn't install any series termination resistors in the lines. I am considering restringing the PCB to add these to the PCB layout but on the proto...

The offset shown in that image was because the datasheet in 2018 for this TFT had the HBP (Horizontal Back Porch) value as 88 pixel clocks, which through trial and error testing I found out was w...

I currently have something partially working in that the display is more stable but I still get horizontal tearing when anything on the left of the screen displays anything other than black pixels....

I have this working. It was the fact I had only made changes in the kernel source but had to make changes to u-boot.Now it almost works except for some tearing of the display that is visible on the...

What is your PCB design like for the power rails to the OLED? Do you have sufficiently wide ground and power rails to it?Where are you measuring the voltage drop? At the OLED?
