And this is a good example: on the LGW 777-200 row 4J/K is a good seat to go for. The worst that can be said is that the window could be better aligned. I personally prefer the 4A seat, and these photos give you an indication of the window layout, albeit from the A side.

and this is the view from the normal head position when in flight take off mode (ie upright) looking out of the window.

One thing to note is that LGW operates 3 core types of 777-200 and the bulkhead is different in all three. So always keep an eye on the seat map, particularly at T-72 and T-24 hrs.
