The quality of the screen is really good. Sound is ok too. The model is fairly basic with just 2 HDMI sockets, a SCART and a USB (music/pictures only). However, by entering the service menu (do a web search for LE40D503 firmware) you can trick it into letting you play video too - however, you may need to use a universal remote to get it to play and pause the video as there are no such buttons on the remote. Nice free upgrade. Sadly it has NO ethernet port so you cannot trick it into access the internet. And also just to clarify, it does not have a freeview HD tuner. You'll need a HUMAX HDR FOX-T2 for that.
Really good bit of kit for the price.
