-==== How to update U-Boot ====
+==== VU8C edid issue  ====
-It's a beta test version so you need to upate u-boot binary\\
+In some amount of VU8C monitors, the edid data has an unneeded resolution, 1152x768 except 1024x768,\\
-and modify boot.ini to activate the functionality.
+so when using display auto detection mode, some part of right side display image can be clipped.\\
-== 1. Download the script ==
-First, download the update script file as following \\
-and then change the mode.

-== 2. Update U-Boot ==
+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>
-$ ./update_c2_boot.sh update
+# Display Auto Detection
-</code>
+# "false" or "true"
+setenv display_autodetect "false"
-== 3. Check the U-Boot version ==
+...
-<code>
+...
-$ ./update_c2_boot.sh version
+# setenv m "1080p60hz" # Progressive 60Hz
-</code>
+setenv m "1024x768p60hz"
-If the update is completed, you can see the following version.
-<code>
-# ./update_c2_boot.sh version
-Now let's check if update has been completed...
-U-Boot 2015.01-00183-g731ba4c-dirty (Feb 01 2017 - 12:08:29)
 </code>
-After updating, you must run **reboot** the system.
+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.\\
