Anguel, circuitco responds to ALL emails sent to supp...@beagleboardtoys.com and supp...@boardzoo.com for products produced by circuitco. we have responded to a number of emails with questions about the jitter issue. we provide recommended configurations and setup for all of the products, however we sell the hardware independently for developers to do as they choose with it. i highlight that fact.... developers. we can not test every single software load out there for every single product. as such a developer is responsible for configuring their own software functionality. we provide a warranty and guarantee on the hardware along with full documentation. one of the ways we keep costs low is for these products to be community supported. if you are unhappy with the lcd cape, we will be happy to refund your money for both the cape and beaglebone black so that you may select something more to your liking. may i suggest the TI AM33x EVM platform? (https://estore.ti.com/TMDXEVM3358-AM335x-Evaluation-Module-P2714.aspx). it retails for $995USD.....
