Hi Iam going to show films in the Garden if we have a Summer I must admit it is one of the cheaper side of the market but it does 1080p I have already got one of them sticks ( Amozon one) but I want to buy a small Blu ray Player. If I buy one of the external type with are normally computer type with only USB if I brought a USB- HDMI cable would I still get full 1080 p going though the projector. If not I do have some films on a USB Stick which I used MAKE MKV would they be full 1080p as I copied them from my computer Blu Ray Drive to the USB Stick
