Check out ProVideo Coalition's detailed review of the PIX-E5 recording monitor.
"I'm not going to kid you. I’m no fan of cameras that make you jump through hoops to perform essential functions, and there is no more essential function than monitoring your picture. If the camera makes using the attached monitor a pain (shall we make a list? Canon? Panasonic? Red? Wave your hands!) then an external monitor is going to be required. So, if you gotta have it, it better be good, affordable, and usable, and if it records video so much the better. Video Devices PIX-E monitor fills this bill admirably.
I tested a PIX-E5, with a gorgeous, bright 5” 1920×1080 LED screen front and center. To say this screen is incredibly sharp is a gross understatement – if you can’t focus your shot with the PIX-E, check your backfocus. (And turn on the peaking too, but more on that later.) The monitor is packaged in an all-metal (yay!) enclosure that measures 5 1/2 x 3 1/2 x 1 1/2 inches and weighs about 1 pound unloaded. This is a package that isn’t going to unduly weigh down many cameras.
Input can come from either SDI or HDMI inputs (the less-expensive PIX-E5H offers HDMI only.) Power is supplied with either an AC supply (with a screw-lock connection on the monitor power jack – another big plus) or by Sony-mount batteries, two of which can mount simultaneously on the back of the PIX-E..."
