4 years ago I found a C# project for EDID that decoded the main block and was expanding it to decode the extension blocks. I was using this tool/site as a way to validate my c# code output. I found a difference between my c# code and this site. After looking at the JavaScript source code I found the copy/paste, paste code that didn't get changed for the later bits. I can read code but I'm not much of a JavaScript developer.
Ya, the checksum might be wrong.. I might have been tweaking the bits to test the code for the different bits... I wasn't too concerned about the checksum, just trying to test each part of each block and different blocks.
Vendor Specific Data Block HDMI 2.0 - Supports 36/48 bits/pixel flags are not correct when they should be set.
The following EDID contains a vendor specific data block. Byte 171 = 07 which means it should support all 3 DC_30bit_420, DC_36bit_420, and DC_48bit_420, however the app is only setting the former.
