(32)The DP4 The VF The DP4-EVF Product IntroductionOn Camera Field MonitorAn affordable, durable, 4.3-inch on-camera monitor packed full of inputs, outputs and professional software features. Extensive menu options plus a simple user interface, means quick and meaningful visual feedback when dialing in crucial details such as focus and exposure.Viewfinder Loupe Accessoryfor the DP4 MonitorAn optical loupe accessory designed to attach to the DP4 Field Monitor. This flip -up eyepiece adds the functionality of an EVF to the DP4, but does not remove its functionality as a monitor.Monitor/Viewfinder ComboThe Resulting combination the “DP4” and “VF” shownabove. The DP4-EVF operates seamlessly as either a4.3-inch monitor or as an EVF by simply flipping theeyepiece up or down and results by combining the“DP4 and “VF” shown above.Caring for your DP4 Monitor* The DP4’s DC input is CENTER PIN POSITIVE. Always check polarity of any custom cable implementations. SmallHD is not liable for any power related damage to your monitor due to incorrect polarity.* The DP4’s max input voltage is 18v DC. Over powering can result in damage to your DP4. SmallHD is not liable for any damage due to overpowering the unit.* Not all power sources are created equal. Using off-brand (non-Canon) LP-E6 batteries can result in undesired performance and longevity issues.* Do not attempt to disassemble the DP4. Doing so voids warranty.* If the DP4 is exposed to significant amounts of water, do not power on and contact SmallHD support. Water damage is not covered by warranty, but taking the right precautions when a water event occurs can sometimes preserve unit functionality.* Clean the screen with a high quality microfiber cloth only. Never spray the screen directly with any sort of cleaning fluid.* Always ask us if you have any questions about general operation. Contact SmallHD at /support*Much more information about the DP4 and other SmallHD products can be found online on our website and in video form at Caring for your DP4-EVF Viewfinder * Heed all instructions listed above regarding the DP4 Monitor* Do not expose the entrance of the EVF lens to direct sunlight. Doing so can magnify the sun and cause damage to the screen.* The aluminum lens assembly is air tight and sealed. Do not attempt to disassemble, as risk of contamination from dirt, dust and moisture can occur.* Clean the outside lenses as lightly as possible with a clean microfiber cloth only.Positioning the EyecupThe EVF Eyepiece is fixed to the assembly in a way that allows easy rotation and removal. The eyecup can also be positioned forward and back for optimal comfort.What should be in the box:DP4 Monitor:1.DP4 Field Monitor2.Sunhood3.Mini-HDMI Cable (1.5ft)4.YPbPr Breakout Cable (4ft)5.Hotshoe Ball Mount Power Supply7.Acrylic Screen Protector8.SmallHD Cleaning ClothVF Only:1.DP4 VF Adapter2.SmallHD Cleaning Cloth3.Circular Eyecup4.Lens CapDP4-EVF Combined:1.All of the aboveDP4 Diagram/ Composite OutPowering the DP4:The DP4 has two methods for powering:* Batteries, using the interchangeable battery plates* AC/DC Power, using the Barrel Power input on the back of the unit.The Power SwitchThe DP4 has a dual position power switch that distinguishes between using battery power, or the rear DC barrel power input. The switch has a depressed state (down) and a raised state (up). To use batteries, the switch should be DOWN. To use AC/DC Power via the barrel power input, the switch should be UP.Battery Plates:The DP4 comes standard with the dual battery plate of your choosing that is removable/replaceable with other types of plates. * Batteries can be used either in a single or double arrangement * Power switch should be depressed to activate battery power* Battery voltage can be read onscreen in the DP4 Menu System by activating “Voltage Meter” in the “System” Menu.Removing Battery Plates:The battery plates are not attached by screws, they just need the correct amount of force applied in the correct places to detach from the DP4 body. Some popping noises may occur during the battery plate removal process—this is normal and expected.Method 1:The recommended method is to insert a small flat-head screwdriver into the corner slot where the battery plate meets the metal body, then pull towards the rear of the DP4, lifting the corner of the plastic plate away from the metal DP4 housing.Method 2:Thread the ¼ 20 thread of the included ball mount into one of the two side ¼ 20 mounts a few times, then pull towards the rear using the body of the ball mount as leverage, while pushing the center of the back of the plate with your thumb.Replacing Battery Plates:Replacing battery plates is as simple as aligning the plate to the back of the DP4 and pressing in on the 4 corners. You should hear 4 audible “click” noises to confirm that it is completely attached.Powering with AC/DC Power:The DP4 has a barrel power input for powering from a wall using the included power supply, or from other sources such as Anton Bauer batteries.The specifications of this plug are below:**ALWAYS CHECK POLARITY BEFORE USING ANY POWER SOURCE THAT ISN’T THE INCLUDED POWER SUPPLY.The DP4-EVF:The DP4-EVF as a unit combines the DP4 Monitor (aka "DP4") and the DP4 Viewfinder Loupe Accessory (aka "VF"), which simply fixes to the front of the DP4 without the need for screws or adhesive. OverviewAttaching the VF to the DP4* Hold the VF with one hand and with the other, put one side of the DP4 in place, and then firmly press down on the other side to snap the VF in place.Detaching the VF from the DP4:Using your thumb, pull one of the side tabs of the VF back, then release the DP4 from that side—the other side will come out on its own once the first side is free.Using the DP4-EVF* The DP4-EVF incorporates magnets and a hinge to operate in two modes, closed and open. This makes it easy to quickly go from shooting mode to review mode, since you will not have to fiddle with latches or screws.* To adjust the eyepiece, simply rotate it to the most comfortable position.* The front of the lens assembly has standard 46mm threads for the use of diopters and UV filters. This will add thickness to the front and in some cases may protrude too far for comfort. This can be resolved by pulling the rubber eyecup back until it is flush around the very first element.Using the DP4Operating the Menus1 –Navigation Scroll Wheel* Click to activate Main Menu* Click to select items in menu* Scroll right and left to adjust values*(From no menu) Scroll any direction to access Preset menu2 –Back button/Preset A* Press to reverse out of the menu* Activate/deactivate Preset3 –Preset B Button* Activate/deactivate PresetActivating the menu and adjusting a function:1 – Click the scroll wheel one time2 – Roll the scroll wheel left or right to the proper sub menu3 – Click the wheel to select the sub menu4 – Roll the wheel to select the desired menu item5 – Click the wheel to select the desired menu item6 – Roll the wheel left or right to adjust the value7 – Press the back button to exit out of the menu systemVideo Tutorial:/Videos/dp4-user-interface-tutorial/DSLR Scale PresetsThe DSLR Scale presets are factory defined presets that enable the input signal from a variety of DSLR cameras to fill the screen of the DP4. Most monitors are unable to achieve this function. Special logic is in play when these presets are activated that keeps the image in full-screen mode even though the video signal may be changing aspect ratios behind the scenes (as in the case of the Canon 5D Mark 2, 60D, T2i, and T3i). As a result, the "Scale" and "CustomScale" menu functions are locked while using these presets.NOTE: Use preset "C DSLR REC" for Canon DSLR cameras during LiveView/Record mode. Use preset "N DSLR REC" for Nikon DSLR cameras during LiveView/Record mode. (*If using the Nikon D800 you can just use preset one on your monitor.) Use preset "PLAYBACK" when reviewing footage already recorded onto the Canon/Nikon DSLR.Assigning Function ButtonsThe DP4 has two buttons that can be assigned to custom functions for a convenient one press on/off of your favorite features.While not in any menus:1 – Press and hold either of the two buttons (A or B) for 3 secondsand release2 – Scroll with the scroll wheel to the desired function and clickthe scroll wheel to select it3 – Press the Back button to exit the menuImage MenuThe image menu controls Brightness, Contrast, Hue, Saturation, Sharpness and Gamma. Below is a description of each. Function Range DescriptionBrightness 0-100 Controls the maximum black point of the signal.Contrast 0-100 Controls the maximum white point of the signal.Hue 0-100 Also known as Tint or Phase.Saturation 0-100 Also known as Chroma.Sharpness 0-100 Amount of edge enhancement is applied.RGB Control 0-100 Adjusts RGB Gain and Offset for all 3 color channels.Gamma 2.2 Standard Gamma adjustment.Advanced MenuThe Advanced menu provides access to the many software tools of the DP4 to, among other things, aid in focus and exposure.Some of the functions are explained in greater detail in later pages, marked by the asterisk (*).Function Range DescriptionFocus Assist + On, Off Darkens image and outlines area in focus in white.False Color* HML, HL Overlays varying IRE levels in specific colors.Peaking On, Off Over-sharpens the image to give a frosted look to areas in focus.1:1 Mapping* On, Off Maps the native signal data to the screen of the DP4 –one native pixel to one DP4 screen pixel, no scaling.Scale 16:9, 4:3,2.35:1,1.85:1,AUTODefines the initial scalingparameters for the DP4.16:9, 4:3, etc.CustomScale 0-1000(x4) Stretch, shrink and move the image on screen pixel-by-pixel.Blue Only On, Off Turns the Red and Green color channels off. Used for calibrating to color bars.Monochrome On, Off Removes all color and leaves only the Luminance data of the signal.False ColorFalse color evaluates the incoming IRE levels (exposure) of the signal and then changes the colors of the pixels to represent what those IRE levels are. This is a quick way to gauge the exposure levels within an image in a very clear way.The DP4 currently has two different types of False Color.False Color HML (High / Mid / Low)Meaning High, Medium, Low, has colors for over-exposed, under-exposed and mid-range. The scale is below:BLUE PURPLE ORANGE GREEN YELLOW False Color HL (High / Low)Meaning High, Low, has colors for over and underexposed. The remaining middle will be monochrome.Image Flip H, V, HVFlip the image horizontally,vertically, or both.Freeze On, OffWhen activated will freezethe image on-screen. Turnoff to resume normal video.1:1 MappingWhen activated, each native pixel of the input signal is mapped to a native pixel on the display. This is also called “Pixel to Pixel”.When viewing HD signals (720p and up), only a portion of the image will be displayed on the DP4 as 1:1 Mapping essentially performs a "zooming" effect on the native HD image.To move the viewable window around:When 1:1 is activated and no menu is being displayed:1 – Roll the scroll wheel to the left2 – Now roll the wheel in either direction to move the window around3 – Press button B to change the direction of movement4 – Press the back button (Button A) to exit this dialogInput MenuThe DP4 has 3 inputs to choose from:1 – HDMI2 – YPbPr (SD/HD Component)3 – Composite (SD Only)Changing inputs:1 –Navigate to the “Input” sub menu with the scroll wheel2 – Scroll to the desired input3 – Click the scroll wheel onceSystem MenuThe System Menu provides access to critical system functions, listed below:Function Range DescriptionVolume 0-100 Controls the output volume to the headphone jackVoltage Meter On, Off Displays the current operating voltage, either from batteries or line power.USB Power Off, 5V Toggles power to the USB port, on or off.Factory Reset Reverts the DP4 back to factory defaultsDisplay On, Off Disables green input indicator text on top right of screenBacklight 0-10 Default set to 5, increase/decrease backlight brightnessMisc MenuThe Miscellaneous Menu simply contains options to change the menu background opacity level, and will display the current firmware version as a reference.PIP MenuThe DP4 allows two signals (1 HD and 1 SD) to be displayed simultaneously using the PIP or POP function, located in this menu.Function Range DescriptionMulti WindowPIP, POP (Full,4:3)Determines the typeof windowed view. SizeSmall, Medium,LargeDetermines the size ofthe window. Position TL, TR, BL, BRPosition of thewindow.Border Black, Blue Border or no border. Sub Source CompositeDetermines thesecondary source. Swap Swap Swaps the two signalsAccessoriesAttaching the Acrylic Screen ProtectorThe included acrylic screen protector is recommended as a precaution, but is not required. With the screen protector in place, the DP4 is much less vulnerable to damage.The screen protector is fixed to front of the DP4 using a temporary adhesive. To apply:1 – Remove the2 protective stickers from the front and back of the screen protector, then remove the 4 small white pieces from backside corners of the acrylic screen protector to expose the adhesive.2 – Carefully line up the screen protector using the top, bottom and side edges to the front of the DP4.3 – Place the screen protector on the front, and apply a small amount of pressure at the corners. It is not necessary to press hard; the adhesive will bond more on its own over time.Attaching the SunhoodThe DP4 Sunhood uses Velcro to fix to the front of the DP4. It works by looping through the two slots on the sides of the battery plate, and then reattaching to itself.Start by feeding one side of the Velcro strap into the slot, and then pulling it tight so the edge of the sunhood is flat against the surface of the front of the DP4. Then do the other side the same way. Keep pulling each side until the tension feels right, then fold the straps back and attach the Velcro.Updating FirmwareThe DP4 has the ability to upgrade its firmware based on new software developments. This is a unique ability of SmallHD monitors, and is very easy to do. To upgrade:1 – Format your USB thumb drive to FAT file system2 – Download the .BIN file from /support3 – Copy the .BIN file to your thumb drive4 – Insert the thumb drive into the included adapter cable and plug the mini-usb cable into the mini-usb port of the DP45 – Hold down the scroll wheel and then turn the DP4 on.6 – On screen instructions will inform when the process is complete.Video Tutorial/Videos/dp4-firmware-update-how-to-guide/WarrantyThe DP4 comes with a one year limited hardwarewarranty.
