I ran that and the tvs preferred res is group 1 mode 4 changed it in config.txt to that setting still nothing

A half related question : While SD cards are awesome for size/weight/etc., how much of a speed advantage would using an external hdd be? I can't imagine an ssd adding any value over a simple 2.0/3.0 mechanical drive being that the transfer rate is bottlenecked by the shared usb 2.0 bus which apparently is divided up by the all ports and the sd card reader. Is a top of the line sd card just as good as an external hard drive or are there any advantages?

I don't want to start any arguments so if a mod can delete this whole topic please?

@rrs run the command in the post directly above yours. It tells you how to do it.

@jnbui79 Any update? I am having this identical issue on my Samsung set. RetroPie works perfectly on every other TV I try it on..... Please let me know. Thanks! -Craig
