There are two different LCD module kits for ODROID-X. One is 10.1inch and the other is 13.3inch. Resolution and other characteristics are almost identical.
Yes. The only difference is the dimension.
Please note the 10.1inch model was all sold out.
BTW, we have one news to whom have purchased 13.3 inch LCD Kit. We have tested 13.3 inch and 14 inch LCD modules together. 13.3 inch LCD price is lower but it's weak since the PCB is outside of LCD frame. 14 inch LCD price is higher but PCB is well located on the back side of LCD. So, we have decided to provide 14 inch upgrade version without any cost to whom purchase 13.3 inch LCD Kit.
