Hi.
Could you mention the DX SKU (article number) of this device ?
Also, show the example sketch you used.
And please put that in [code] [/code] tags.
This might shed some light on the problem, but we need both SKU and sketch.
I did receive a defective display in a similar DX offer, but that didn't show anything (no first row boxes like yours), confirming floresta's answers.
In the unlikely case this would be a defective display, my experiences with DX in such cases are positive.
But you have to be absolutely sure that there is some defect instead of a software failure.
