Hello, Today I am reviewing the Neewer F400 Pro Field monitor. The Monitor itself is a 6 inch - 1080P(1920 x 1080) IPS camera display. The Box contains everything to get you going …The Monitor, L-mounting bracket, Battery (NP-F550), Battery Charger and USB cable, HDMI to Mini HDMI cable, HDMI to Micro HDMI cable, Cold Shoe Adapter, RCA type AV cable, power cable for connecting dummy battery, Sunshade and hood and a cleaning cloth. As you can see they include a lot of stuff and Neewer has always made affordable quality Photo and Video accessories. This monitor is no different, it feels solid and when mounted with the included L bracket seems sturdy with no worries.When the monitor is on the L bracket it can be positioned Landscape or Vertically viewing. You can also adjust the viewing angle easily as well. The Monitor has a Standard HDMI input as well as an AV input (RCA cables included). There is a 3.5mm headphone jack to monitor audio and lastly a power input ( cable not included) if you want to run it without batteries…you will need a 12v 2A ( 5.5MM OD). On the bottom of the monitor there is a Power output port for hooking up a dummy battery to your camera the cable is included but not the dummy battery…I like this feature if you where doing a long event or recording. Nice touch Neewer! There is also 2 x 1/4in mounting threads - one at the bottom and one one the side in which the L bracket uses but you could mount it the monitor on a tripod or ball head instead of on top camera no problem.The monitor can accept a 4k signal but can only display 1080p which is fine its more for framing your picture/video than watching. The screen is officially stated as having 500 nits and 1000:1 contrast ratio for those interested in the numbers. The hookup is simple HDMi to the mini/micro HDMI on your camera turn the camera On and the monitor ON using the Power Button on top of the monitor and your should have a feed. At this point you may have to make some adjusts in your camera settings ..In my case I have a Sony A6500 and I wanted to see both the F400 and the Sony screen at the same time. Once o you have your camera outputting the way you want its time for the F400 settings. On the top of the monitor are 4 buttons 3 are Hotkeys and the last one is a Menu button with a scroll wheel beside it. There are 5 areas to select: Picture - These settings are for adjusting the picture on the screen not the camera! You can change the mode to standard, Vivid, soft and user. Somethings to change are brightness, saturation color temperature and contrast. I found Standard to be just fine. Marker - Here you can set aspect ratio markers and safety markers to help better frame your shot. Function- This is where you can set the aspect ratio of the monitor and zoom in on the image. The Pixel to Pixel option is a must ON and I Leave the Aspect to Auto and then what ever your doing on the camera wether its 16:9 or 4:3 the monitor with follow that size. Waveforms - These selections are going to appear as a OSD ( on screen display ). Waveforms such as Histogram, RGB WFM , Audio levels, vector display and peaking levels and color. And my favorite is Exposure helps you get better shots. System- Is where the basic monitor settings live, like input source, language and OSD settings. The hot keys can be set up here so you can assign a function to one of the three hotkeys on the top of the display - pretty much everything can be assigned to these. The volume for the 3.5mm headphone jack is also managed here, as is the RESET in case you went a little overboard on the color setup. Here is where I wish they had an option to have a sleep timer adjustment as my camera goes to sleep after 5 min. but the monitor stays on for 30min. wasting battery life. There is a USB port on the one side.. don’t get that confused with a regular USB port it is strictly for upgrading the Firmware on the monitor. In use, found it very easy to use and helpful in many ways, I’m not a pro photographer or videographer so I use this monitor as a helpful tool to frame and set up shots easier. The monitor is fantastic addition to the tiny screens that digital cameras have. The battery life is good and easy to charge using a portable charger on the go. The sun shade is so handy to have and its included which is why I love Neewer products .. They are about giving the customer value and the F400 is a great representation of that. You get a terrific field monitor, all the accessories you need, for a reasonable price. Totally recommended!
