What to do when my second monitor displays a different resolution?

LCD monitors, including laptop screens, typically run best at their native resolution.  You don't have to set your monitor to run at this resolution, but it's usually recommended in order to ensure you see the sharpest text and images possible.  LCD monitors generally come in two shapes: a standard proportion of width to height of 4:3, or a widescreen ratio of 16:9 or 16:10. A widescreen monitor has both a wider shape and resolution than a standard ratio monitor. If you're unsure of your monitor's native resolution, check the user guide for this information. To change your screen resolution 1. Open Screen Resolution by clicking the Start button clicking Control Panel, and then, under Appearance and Personalization, clicking Adjust screen resolution. 2. Click the drop-down list next to Resolution, move the slider to the resolution you want, and then click Apply. 3. Click Keep to use the new resolution, or click Revert to go back to the previous resolution.

Why does image persistence occur with my LCD monitor?

Image persistence (or image retention) is a result of a stationary image being displayed for a long period of time.  Unlike CRT monitors, image persistence or "Burn-In" is not permanent on LCD monitors.  To recover from "burn-In" on an LCD, leave the panel OFF for an extended time. To prevent image persistence, we recommend the use of a screen saver when the monitor is not in use. Image persistence on LCD screens can be corrected in most cases and is easily prevented.  Prevention of image persistence can be done through some of the following methods: 1. Set the screen to turn off after a few minutes of screen idle time under the display and screen preferences in the operating system.      Turning the monitor display off will prevent an image from being displayed on the screen for extended periods of time.      Setting it to do this when idle for fifteen to thirty minutes can make a huge difference.      These can be adjusted in the Mac Energy Saver settings or Windows Power Management. 2. Use a screen saver that either rotates, has moving graphic images or is blank.      This also prevents an image for being displayed in screen for too long. 3. Rotate any background images on the desktop. Background images are one of the most common causes for image persistence.      By switching backgrounds every day or few days, it should reduce the chance of persistence. 4. Turn off the monitor when the system is not in use.      This will prevent any problems where the screen saver or power function fails to turn off the screen and result in an image sitting on the screen for long times.

What to do when image is pixelated?

What to do when no image from my monitor?

1. Check Power Check to make sure the monitor is turned on, which is usually indicated by some kind of light on the power button itself.  If the light is on, the monitor is on and you should see some message. If the monitor is on, but nothing is showing up, try to press the menu button to bring up the built-in monitor controls.  If still you have a blank screen, then this could mean there is a problem with your monitor.  Even with nothing connected, you should be able to bring up the monitor menu.  Try connecting a different monitor if you have one. If a separate monitor works fine, then it could mean the power supply is bad on the original monitor.  Try replacing the power supply, if an external power supply is available, and see if that fixes the issue. Now check to make sure the computer is properly turned on.  The main thing here is to check for any warning lights or unusual beeps when you power on your computer. If the power button or one of the status lights is red or orange or if the computer beeps several times when turning on, this is indicative of an internal problem. If the power is on and everything looks fine, but you’re still not getting anything on your display, the computer may have gone into standby or sleep mode and isn’t being woken up. Try pressing keys on the keyboard or moving the mouse. If none of that works, try restarting the computer by pressing the power button. 2.  Check Cables The next easiest thing to do is to check all the cables. Whether you are using VGA, DVI, HDMI or DisplayPort to connect your computer to your monitor, cables can sometimes become detached. This is especially true for cables that don’t screw into the back of a monitor. Make sure you check the connection at the PC and on the monitor. For those of you who have more than one video card, you need to be careful how you connect the monitors. If you have a dedicated graphics card, then make sure the monitor is connected to the graphics card and not to the motherboard video connection. By default, Windows is supposed to disable the motherboard graphics automatically when you have a separate graphics card, but sometimes this doesn’t happen. If the cables are connected and you only have one video connection, then you need to rule out bad cables. To do this, you need to find another monitor to connect your computer to. If the screen is blank on the second monitor also, then it could be an issue with the video cable. Try replacing the video cable or using a different video cable if you have multiple connections options like DVI, HDMI, etc. If using VGA works, then it could mean there is an issue with your HDMI or DVI cable. 3. Check Source Lastly, you should also make sure that the input source on your monitor is set to the correct input. Most monitors normally auto-detect the input source, but sometimes this feature can become disabled. Press the number 2 button on your monitor to scan input sources, it will automatically scan all sources and stop when a source is detected.

What to do when my AC adapter does not work?

Verify adapter plugged into a wall outlet Make sure the AC adapter is firmly and securely plugged into the wall outlet.  Although it may sound obvious, the adapter can become loose without even knowing.  If it's not plugged in all the way, it can make it seem like the adapter is not working, but it may just not be getting power from the wall outlet.  When in doubt a good way to make sure it is plugged in properly is to disconnect and then reconnect the connection. Check adapter indicator light The AC adapters may have a power indicator light on the adapter brick.  Check for this indicator light and if there is one, make sure it is light up with a green light.  If you see a power indicator it is a good indication that the adapter is at least receiving power. Check the wall outlet itself Some wall outlets require a light switch to be in the on position for the outlet to be active.  Many newer houses, apartments, and condos feature this type of wall outlet.  If the light switch is on, verify the wall outlet is working in general.  Use a volt meter to measure the power output and verify the outlet is functioning properly.  Alternatively you can also try another wall outlet. Also, double check the circuit breaker and make sure nothing is tripped or turned off. Check adapter brick connection Most AC adapters come in two pieces. Make sure both of those pieces are connected firmly and securely.  The two pieces connect at the rectangular box piece, often called the brick. You can verify the connections by disconnecting and reconnecting all cables. Adapter plugged into monitor Although it may seem obvious, the adapter can become disconnected from a monitor.  The metal tip on the adapter cord needs to be firmly attached to the monitor for it to receive power from the adapter.  Also, in either the metal tip on the adapter or the connection on the monitor, there is often a small metal pin.  Make sure this pin is not bent or broken as that can cause a problem with the monitor receiving power from the adapter. Replacement If you have determined the AC adapter is not working properly and needs to be replaced, you can get a replacement from our parts store or contact customer service for a replacement if the unit is still in warranty.

Why does it show "Out of Range" when connecting monitor to my desktop PC?

This happens when the screen resolution is set to something higher than what the monitor can display.  For example, if the monitor supports resolutions of up to 1080x1920 and the video card allows up to 2460x1440, setting the resolution to the highest setting will display the error.  Another reason this error may come up is when the refresh rate that is selected is higher than what the monitor supports.  The monitor can't "sync" with the video card, so it just displays an "Out of Range" error.  Also, if the resolution is set at a reasonable amount, make sure that the monitor is plugged in all the way. If the message is displaying on a secondary display simply go to Windows Display properties and change the resolution setting of the secondary display to a lower setting until and image is displayed.  It is recommended that the native resolution of the display be used. To change your screen resolution 1. Open Screen Resolution by clicking the Start button , clicking Control Panel, and then, under Appearance and Personalization, clicking Adjust screen resolution. 2. Click the drop-down list next to Resolution, move the slider to the resolution you want, and then click Apply. Click Keep to use the new resolution, or click Revert to go back to the previous resolution If the error message is on the primary display when booting Windows, try to boot into Safe mode to change the display settings. Hold down the F8 key while the computer is starting up and choose "Safe Mode" from the list of options that appears on the screen. This should force the display to be a low enough resolution so that it will work. On a Mac, hold down the Shift key while booting up to start with extensions off, and that will usually do the trick.

If there is a yellow exclamation mark under the display adapter section or if there are generic display drivers loaded, the monitor may not display the correct resolution or the monitor will not be seen as a secondary display. A message like the one below may also appear during or after updating to Windows 10. The image below displays an NVIDIA video card but the problem can occur with any video card that does not have updated Windows 10 drivers. In this case, drivers for the systems video card must be updated. Drivers can be located from the computer’s manufacturer or the video adapter manufacture’s website. Display Resolution Does the computer allow the monitors native/prime resolution in display properties? To check the Display Properties follow these steps: (Figure 2) Single right-click on an empty spot of the desktop and select Properties. Select Display Settings then, Advanced display settings.

Why is there shadow or double image on screen?

Extension cables, docking stations and longer cables may be prone to ghosting, lines, double images, or poor focus.  The improper shielding of the extension cables will cause a shadowing or ghosting effect.  This improper shielding causes a mismatch of the input impedance between the video card, the video cable, and the monitor. In addition, if using a switch box or low quality cable, these two items will also cause signal degradation.  Check the video cable to make sure all the pins are in good condition.  Test the monitor on a different computer.

Why is there touch response randomly on my TD2421 even nobody touches the screen?

TD2421 is an optical touch monitor which uses two CMOS cameras (optical sensors) placed in the corners at the top of the screen as well as three reflectors (light strips). These cameras are used to look across the entire touch surface for touch events. When an object touches the screen, it blocks some of the light being received by the sensors in the cameras. The location of the touch is then calculated by using the information from both cameras and the mathematical principles of triangulation. Pros of Optical Touch Screens Entire screen including the corners is sensitive to touch Images are crystal clear because no coating is used on the panel Panels last for a long time as only a light touch is needed to register an input Support multi-touch events and gestures Scales with perimeter and not area However, even with those pros, there’s also some limitation. Performance may be interfered/affected by direct sunlight or reflections from wet or shiny surfaces. That’s why it’s observed to receive touch signal randomly while exposed to sunlight. Please avoid exposing the monitor to direct sunlight or glare reflection as mentioned in the user guide as below.
