perhaps you could be a bit more specific? CX has 4 types of 777 configurations (77H, 77G, 772Z and 773Z) across 3 different variants (777-300ER, 777-200, 777-300).

772Z and 773Z have the awful regional configuration.

77H and 77G have the pretty darn good Cirrus configuration, although agreed IFE screen is a little outdated.

But honestly, if you're going to complain at least make it well-rounded...I also fly nearly all the competition. CX has a top-5 system with StudioCX in terms of interface and variety, especially if you care about English or Chinese-language TV and movies. I agree the resolution is a downside but really, people can always find reasons to complain. JAL, for example has a huge screen in J and F but that system is buggy (I can't recall who, but at least one or two other carriers use it), and the offerings are definitely far inferior for a native English and Chinese speaker.

and...here is the list we keep maintained of all CX configurations.
