In this video, learn how to use the monitor's on-screen display to control the monitor's brightness, contrast color temperature, and input selection.
- A malfunctioning monitor is frequently confused with a broken computer. That's because the monitor is visual, and as the PC's primary output device, it's easy to believe that the entire computer is broken, when it's just the monitor that doesn't work. But there's more to a PC's graphic system than just the display. Inside the console, you'll find the computer's display adapter. It's either circuitry on the PC's motherboard, or stored on an expansion card. And together with the monitor, it comprises the PC's graphic system.
The monitor connects to the graphics adapter using a video cable. A power cable connects the monitor to the wall. Surprisingly, all of these cables must be connected before anything works. Check your cables and connections. Further, both the computer and monitor must be powered on. The monitor may have a power button or touch sensor. This button or sensor has a lamp, which is illuminated when the monitor is on. Further, most monitors use power saving technology, so the button is one color when the monitor is asleep, say yellow, and another when the monitor is awake and receiving a signal, say green or blue, and when the monitor is off well, the lamp is just not gonna have any color.
So, if a monitor is on, but the power button is yellow, then it may mean that the monitor is working but the problem is with the graphics hardware inside the computer. To control the monitor or modify its settings, you use an onscreen menu. It's rare that you need to access this menu, and no uniform technique is used to summon the menu. Each monitor is different. On this monitor, you press this button, and there's the menu. You use this menu to adjust the display's physical aspect.
You can set brightness, contrast, and color temperature. The brightness and contrast settings may help you fix a dark display, or one that's too bright. Try not to over adjust the monitor too bright, which is hard on the eyes, especially in a dark room. Some monitors may sport an auto brightness feature, based on the ambient light in the room. If your computer's monitor has such a feature, use it. The color temperature settings control the color of the light the monitor generates.
You can set the temperature to produce warm white tones in the yellow range of the spectrum, or cold white tones in the blue range of the spectrum. So, if the monitor shows white colors that are too blue or too yellow, use the monitor's menu to adjust its color temperature. Monitors that feature multiple input sources have a switch that sets which input to use. For example, if your monitor is connected to both a game console and a PC you use the input switch menu to select one source or the other.
Look on the monitor's menu buttons for an input switch, or summon the onscreen menu to choose the input. Sometimes the input source is selected automatically, depending on which gizmo is currently active. If you've checked all the connections and inputs and nothing shows up on the monitor, then try swapping out the monitor with one that works. Disconnect the monitor's power and video connections, replace it with a second monitor, the one that works, and connect the power and video. You can perform this task while the computer is on.
Now, if an image appears on the replacement monitor, then you know it's the old monitor that's to blame. Yes, monitors can break, especially if it's an older unit, and monitors contain no user serviceable parts inside. They must be replaced. Also, many localities don't permit you to throw away a monitor in the trash. Please, properly dispose of old monitors, as well as old technology or electronics, in the manner prescribed for your locality.
