• How do I remove the Demo Mode on my 28in UHD LED CrystalPro 4K 60Hz DisplayPort, HDMI/MHL, DVI Monitor (Picture In Picture |Picture By Picture) - Black / Aluminum Bezel?
    In order to leave Demo Mode, you would need to press and hold the Select button for about 8-10 seconds.

    Pressing the Select button for 8-10 seconds, when not in Demo Mode, will activate Demo Mode.

  • I am receiving no signal or my monitor’s screen is blank or on a black screen, how do I change the source on the monitor?
    There are varies methods to changing the source on a monitor, so please refer to your user manual on specific directions in regards to your specific monitor.

    But in general, to choose a source, make sure the monitor is on, then press the "source" button, until the input is selected, then press the "+" button to finalize it. 

  • Interpreting Monitor Specifications
    Display Type: This is the panel technology the monitor is using. The most common variants are TN (Twisted Nematic), MVA (Multi Domain Vertical Alignment), IPS (In Plane Switch) Please see our screen comparison here for more details.

    Screen Size: The screen size of the monitor measured diagonally.

    Dot Pitch: How sharp the displayed image can be.

    Maximum Resolution/Native Resolution: The maximum resolution that the monitor supports. Ideally you want to output the resolution that the monitor natively supports for best picture quality and clarity.

    Brightness: Measured in candelas per square meter (cd/m2) is the measurement for luminance. It is also equivalent to the measurement “Nits” that is used in many other specifications and devices.

    Viewing Angle: The angle at which the screen can be viewed without color distortion or inversion. Most VA/IPS panels have wider viewing angles than TN panels and are more ideal for being viewed in a larger room. Smaller viewing angles equates for the user to be directly in front of the monitor for best color distribution and clarity.

    Vertical Frequency: Is the refresh rate the monitor refreshes the image at measure in Hertz(Hz), most monitors have 60hz, but a few gaming models do have 120hz and 144hz for more fluid and faster refresh rates.

    VESA Mounting pattern: Is the 4 screw pattern on the back of the TV measure in millimeters. This determines any desk type mount or any wall mounts compatibility with the monitor you will be ordering so make sure it fits.

  • What are the different common types of Touch Screens?
    Touch screen technology has the potential to replace most functions of the mouse and keyboard. The touchscreen interface is being used in a wide variety of applications to improve human-computer interaction. As the technology advances, people may be able to operate computers without mice and keyboards. Because of its convenience, touch screen technology solutions has been applied more and more to industries, applications, products and services, such as Kiosks, POS (Point-of-Sale), consumer electronics, tablet PC, moderate to harsh Machine Control, Process Control, System
    Control/Office Automation and Car PC, etc.

    The touch panels themselves are based around four basic screen technologies: Resistive, Capacitive, Infrared (IR), and Surface Acoustical Wave (SAW). Each of those designs has distinct advantages and disadvantages. Many of these are designed to comply with specific National Electrical Manufacturers Association (NEMA) standards to meet various installation requirements.

Each of those designs has distinct advantages and disadvantages. Many of these are designed to comply with specific National Electrical Manufacturers Association (NEMA) standards to meet various installation requirements.

    A resistive touchscreen panel comprises several layers, the most important of which are two thin, transparent electrically-resistive layers separated by a thin space. These layers face each other, with a thin gap between. One resistive layer is a coating on the underside of the top surface of the screen. Just beneath it is a similar resistive layer on top of its substrate. One layer has conductive connections along its sides, the other along top and bottom.

    Resistive touchscreens respond to the pressure of a finger, a fingernail, or a stylus. They typically comprise a glass or acrylic base that is coated with electrically conductive and resistive layers. The thin layers are separated by invisible separator dots. When operating, an electrical current is constantly flowing through the conductive material. In the absence of a touch, the separator dots prevent the conductive layer from making contact with the resistive layer. When pressure is applied to the screen the layers are pressed together, causing a change in the electrical current. This is detected by the touchscreen controller, which interprets it as a vertical/horizontal coordinate on the screen (x- and y-axes) and registers the appropriate touch event.

    Resistive type touchscreens are generally the most affordable. Although clarity is less than with other touchscreen types, they're durable and able to withstand a variety of harsh environments. This makes them particularly suited for use in POS environments, restaurants, control/automation systems and medical applications.

    Resistive screens use a flexible membrane with a coating of transparent metal oxide and a grid of spacers to locate the touch point. The metal oxide coating and spacers may reduce the picture quality and brightness. The key advantage of resistive touch technology is the wide range of pointing devices e.g., a gloved finger, finger nails, credit card pens, etc. that can be used with it.

    Capacitive touchscreens consist of a glass panel with a capacitive (charge storing) material coating its surface. Unlike resistive touchscreens, where any object can create a touch, they require contact with a bare finger or conductive stylus. When the screen is touched by an appropriate conductive object, current from each corner of the touchscreen is drawn to the point of contact. This causes oscillator circuits located at corners of the screen to vary in frequency depending on where the screen was touched. The resultant frequency changes are measured to determine the x- and y- co-ordinates of the touch event.

    Capacitive type touchscreens are very durable, and have a high clarity. They are used in a wide range of applications, from restaurant and POS use to industrial controls and information kiosks.

    Capacitive touchscreens sense electrical signals to determine the presence and location of your finger as it makes contact with the surface of the touch screen. Strengths of capacitive technology include a fast response time, durability and a tolerance for surface contamination. Grease, water and dirt will not interfere with the capacitive screen's speed, accuracy or resolution like they can with surface acoustic wave or infrared touchscreens. Unfortunately, this technology only works with a conductive, grounded pointing device (like a finger) so in environments where gloves are required this is not an appropriate solution.

  • What is DPI and why is it important?
    DPI stands for dots per inch and it determines clarity and crispness to a display. This is determined by the size of the screen and its resolution. The higher the DPI the less the individual pixels can be discerned on the display. This is also dependent on the distance that the screen is being viewed from. At a long enough distance the human eye will not be able to discern individual pixels regardless of DPI and will look the same. Most monitors range around 100-200 DPI(depending on the screen size) while smartphone screens are more condensed and range from 300-600 DPI. Ideally you want higher DPI for best clarity and picture quality crispness, keep in mind that in regards to computer monitors and computer systems higher resolution/DPI requires more graphical horsepower and so will require a higher end video card to power the system. In regards to smartphones higher DPI screens will have higher resolutions and will generally consume more battery life and graphical horsepower to power the screen.

  • What’s the difference between 8 and 10 bit color depth? What does it really mean?
    The specifications for 8 and 10 bit color depth is 8 bit is 16.7 million colors whereas 10 bit is 1.07 billion. Just as the case with HDMI, for 10bit 1.07 billion colors to be shown on your monitor, all devices must support it. That means the source, whether it be a computer video card, a game console, set top box, DVR or Satellite box as well as the cable and the monitor/TV must ALL support it for 10 bit color depth to function. Please keep this in mind when selecting your components.
