1 Getting Started
  Q Where is the best position to set up my GNR monitor?
  A The monitor should be placed a minimum distance of at least 16" away from your eyes but it is recommended to be up to 30" away. The monitor should be positioned so that you are looking slightly down or that your eye (when seated) is level with the top edge of the monitor. Try to locate the monitor away from reflections and glare.
  Q What else should I check before setting up?
  A Your seating position and desk are arranged so that your arms are approximately horizontal when typing. A footrest should be considered to reduce pressure on the back of the legs.
  Q What is the best way to clean my GNR monitor?
  A A non-moist anti static cloth. Be careful to not use water on or near your monitor.
  Q How do I install/reinstall my GNR monitor drivers?
  A Check the link on the GNR website: wwwgnrintl.com
  Q Where can I find the latest drives for my GNR monitor?
  A Check the link on the GNR website: wwwgnrintl.com
  Q Can I use my monitor with 'Windows XP'?
  A Yes, GNR monitors are compatible with all major operating systems including XP.
   
2 Screen problems
  Q My monitor screen is blank?
  A Check that the power cord and video leads are connected correctly and the power is turned on
  Q My monitor loses power intermittently?
  A Check that the power lead has been connected correctly to both the PC and back of the monitor
  Q How can I reset my GNR monitor back to the default factory settings?
  A Simply by using the On Screen Display function on the monitor front bezel.
  Q The LED light indicates my monitor is on standby and I can't get a picture?
  A Please ensure that the video lead is connected correctly between the back of the monitor and the video card on the PC. Also ensure that the power cord is connected correctly.
   
3 Warranty

  Q What is the warranty on my GNR monitor?
  A If the monitor is faulty, GNR will arrange for a collection and replacement/repair up to three years from date of purchase.
  Q How do I register the warranty for my GNR monitor
  A Please register using the GNR Registration form.
  Q Can I buy an extended warranty?
  A Yes, please email info@gnrintl.com
     
4 Display Technology
  Q What is a pixel?
  A A pixel is a tiny coloured dot on your display either Red, Green or Blue.
  Q What does resolution mean?
  A When referring to monitors and video cards, resolution is used to reference the display format, e.g. 640 x 480, 800x 600 etc. In a more general sense, it refers to display quality/clarity, which can hinge on dot pitch, pixel convergence, pixel depth and other factors.
  Q What is meant by refresh rate?
  A 'Refresh rate' means the length of time taken for a screen to redraw itself within a given period. 85ms is suitable.
  Q What does 'Video Bandwidth' mean?
  A Video bandwidth refers generally to the highest input frequency the monitor is manufactured to handle; the greater the bandwidth, the greater (higher and faster) the horizontal and vertical scanning capabilities.
  Q What are 'video card', 'display card', 'display adapter', 'video adapter', 'graphics adapter' and 'graphics card'?
  A Different names for the card which connects the PC to a monitor.
  Q Which are better, interlaced or non-interlaced monitors?
  A Non-interlaced monitors are considered superior because they tend to flicker less.
  Q What is the difference between slot pitch and dot pitch?
  A Cathode Ray Tubes (CRTs) such as Sony Trinitron and Mitsubishi Diamondtron use a type of light filtering which relies on a series of overlaying slotted grills, rather than grills with holes in them. In general terms, the lower the dot pitch number (i.e. .25mmm as opposed to.28mm) the higher the quality tube.
  Q Why are flat screen models preferable?
  A Flat screen monitors are more valued for their ability to reproduce more accurately the printed page. They also tend to have less glare since flat surfaces have fewer angles to pick up and reflect glare.
  Q What is the difference between CRT and LCD (or 'Flat Panel') monitors?
  A The technology used in creating LCD screens mean that LCD screens are up to 10% thinner than conventional CRT monitors. LCDs also give off less heat and electromagnetic emissions.
   
5 Safety Standards
  Q What is MPR-II?
  A The MPR-II rating signifies compliance with Energy Star's rating for low electromagnetic emissions. MPR-II rated monitors are less likely to cause health related problems given that there may be a link (it is still scientifically unconfirmed) between EM radiation and a variety of illnesses.
  Q What is the advantage of a 'TCO' rated monitor?
  A TCO is a Swedish standard relating to display monitors. More details can be found on http://www.tco.se
     
6 Acronyms
  Q What does CRT mean?
  A Cathode Ray Tube.
  Q What does OSD mean?
  A On Screen Display
  Q What is VESA?
  A VESA stands for Video Electronics Standard Association.
  Q What is VGA?
  A VGA is short for Video Graphics Array and is an IBM defined resolution of 640 x 480 with 16 colours.
  Q What is SVGA?
  A The generally accepted definition of SVGA is 800 x 600 with a minimum of 256 colours at that resolution
  Q What is AGRAS?
  A AGRAS is short for the anti glare, anti-reflective and anti static properties of a monitor, which alleviates eyestrain by eliminating shine.
  Q What does USB mean?
  A Universal Serial Bus. This method of connectivity is becoming widely accepted by simplifying and standardising cables and ports.

8 No drivers
  Q Why there is no driver for my LCD monitor?
  A For most of the LCD monitors in the market, there will be a DDC chip featured in the monitor device.

When the device is power-on and attached to the PC, the signals start to transmit between PC and the device. The device automatically calls for PC's plug and play driver, of which is the standard driver built in all Windows system. Therefore, it is not necessary to have LCD monitor driver enclosed in the package. Each LCD monitor is with fixed pixels, and digital type display. So, the driver is standard from the operation system to support.

The CRT monitor is common to bundle device driver for its variable analogue type display.
9 Definition of pixel fault
  Type 1 Complete pixel constantly illuminated (white spot)
  Type 2 Complete pixel not illuminated (black spot)
  Type 3 One or two sub pixels constantly on or off or intermittent fault. May blink or show a pixel as a base colour (Red, Blue, Green, Cyan, Magenta or Yellow)
     
  Cluster 1. More than one Type 1 or 2 malfunctions within a 5 x 5 block of pixels
  Cluster 2. Several Type 3 faults within a 5 x 5 block of pixels
