 There are a variety of issue related to setting display mode with various monitors\\
 and the available display modes that are provided on ODROID-C2 are limited to support all of them.\\

+==== VU8C edid issue  ====
+In some amount of VU8C monitors, the edid data has an unneeded resolution, 1152x768 except 1024x768,\\
+so when using display auto detection mode, some part of right side display image can be clipped.\\
+If you have the issue, please set a display mode as "Manual mode" and "1024x768p60hz" as following,\\
+then you can see the normal display without the problem.
+<code>
+# Display Auto Detection
+# "false" or "true"
+setenv display_autodetect "false"
+...
+...
+# setenv m "1080p60hz" # Progressive 60Hz
+setenv m "1024x768p60hz"
+</code>
+Or if you want to update edid data of your VU8C converter board, please find the below link.\\
+We're preparing to release a new edid data binary by adjust the detailed timing table to fix ODROID-C2 display auto detection issue.\\
+Once we've done, the update status will be specified here.\\
