LCD display with TN panel.ExplanationLCD displays with TN panels are the most common technology used by LCDs. TN panels have very good response times (1-5 ms) and refresh rates (60-144 Hz), so they are great for PC gaming. They are more affordable and have faster response times than LCDs with IPS panels, use far less power than a plasma display, and far more affordable than OLED displays.

  • What is the difference between UXGA and WUXGA displays?
  • You are putting together a gaming system and need to make sure you get a display that meets your needs. The display needs to have a very good response time, and you would prefer that it be affordable and power efficient.Which type of display is most likely to meet these needs?
LCD display with IPS panelExplanationLCD displays with IPS panels have the best colour representation quality and viewing angles among LCDs. TN panels have imperfect colour representation due to the fact that only 6-bits per colour can be displayed and have poor viewing angles. LCDs with IPS panels use far less power and run much cooler than plasma displays. They are more expensive than LCDs with TN panels but are still more affordable than OLED displays.

  • You have a friend who is offering to sell the monitor and video card from his gaming system along with several PC games. The games have fast moving graphics, and you want to be able to play them on your own home system. The monitor he is selling is an LCD TN with a 144 Hz refresh rate. The video card he is selling supports a max refresh rate of 144 HZ. You want to buy the games, but you have a couple of other choices when it comes to the monitor and the video card. The monitor in your current system has a 60 Hz refresh rate. The video card has a max refresh rate of 75 Hz. This configuration has always worked fine for watching videos. You're also looking at new 60 Hz LCD IPS monitors and several high end video cards with max refresh rates of up to 240 Hz.Which of the following options will allow you to play the games on your home system with the best gaming experience possible?

Change the screen resolution to the native resolution of the monitor.ExplanationLCD monitors have a native display resolution. The native display of this monitor is 1600 xWhile it might be possible to set the resolution lower than the native display, you should use the native display setting for the clearest picture.Using a DVI-D cable is the same as using a DVI-I cable-- both will give you digital output. Using a DVI-A cable (if it will work on the monitor) could result in lower quality images as you will be using an analogue signal. Increasing the colour depth increases the number of colours that the monitor displays.

  • Which of the following statements are true about the DisplayPort interface for connecting video monitors to computers?
  • You have purchased a 1600 x 1200 LCD monitor and connected it to the DVI-I port on your computer using a DVI-D cable. You configure the screen resolution at 1280 x 1024 with 24-bit colour. The display output seems to be fuzzy and stretched. What should you do to correct the problem?
DisplayPort can send both video and audio signals over the same cable.DisplayPort uses a lower voltage than DVI or HDMI.ExplanationDisplayPort is an alternative to an HDMI connector. DisplayPort uses a different signal format than DVI or HDMI. However, DisplayPort supports sending DVI or HDMI signals over the same port using a simple adapter.DisplayPort uses a digital-only signal. To connect a VGA monitor to a DisplayPort, you will need a special active converter that reformats the signal for analogue devices. Like HDMI, DisplayPort can send audio signals over the same cable (if audio is supported by the video and monitor).DisplayPort uses lower voltage than DVI and HDMI.

D-shaped with 15 pinsExplanationA VGA/SVGA monitor uses a high-density (three-row) female DB-15 connector on the computer. Some printers use a Mini Centronics connector, which also has 36-pins. A 6-pin mini-DIN (PS/2 connector) is for keyboard and mouse. DB-9 (serial) connector is for specialized input devices.

  • Which of the following are true of the SXGA screen resolution?
The aspect ratio is the proportion between the width and height of a resolution. Aspect ratios are used by both display devices and video content. The following are the three most commonly used aspect ratios:4:3 is used primarily by analogue TV broadcasts and older flat-panel and CRT displays. Typical resolutions include 800 x 600 and 1600 x 1200.16:9 is a widescreen aspect ratio used by HDTVs, computer displays, and most production films. Typical resolutions include 1280 x 720 and 1920 x 1080.16:10 is a widescreen aspect ratio used exclusively by computer display devices. Typical resolutions include 1680 x 1050 and 1920 x 1200.

  • Which of the following is true of modern LCD monitors regarding backlighting?
LEDs are used to backlight the screen.ExplanationModern LCDS use LEDs (light-emitting diodes) to backlight the screen.Older LCD monitors use cold cathode fluorescent lamps (CCFLs) for backlighting. Plasma displays use millions of small cells that contain electrically charged ionized gases and don't need backlighting. RGB-LED displays are available on modern LCD displays; they gave an array of special LEDs that are able to emit red, green, and blue light, resulting in superior colour accuracy but as the most expensive type of backlighting technology.
