Frequently Asked Questions
> How do I fix screen flickering？
1. Check your cables – In most cases, a defective cable can cause the signal to break while being transmitted across the wire and cause flickering or color distortions. Try using a different cable that you know is not defective or test the cable on other devices. Additionally make sure your cable is plugged in all the way and inspect the cable for bruises, cuts, and bends in the pin.
2. Test your video ports – Another solution is to use a different port on the monitor as video port can also become defective. For example, if you are connected using Display Port, try DVI-D or HDMI instead to see if the problem persists. Note; if you were to find the problem with your port, check both ports on the computer and monitor to narrow down the problem.
3. Check your surroundings – In addition to hardware issues, electromagnetic fields can also cause screen flickering problems. If you have any fans, speakers, fluorescent lights, radios, high voltage units and even cell phones running next to the monitor can cause problems. Simply, place it away from the monitor and remove the devices from the same power strip to reduce interference.
4. Troubleshoot your graphics card- Although it’s rare, graphics card failures do occur and will obviously have effects on your monitor. First, make sure your graphics card is updated with the latest AMD graphics driver. Running on old drivers will cause your graphics card to have issues with your operating system. Second, check the graphics card is properly seated in the slot and then make sure your graphics card is not gone bad or defective by switching your graphics card with a spare.
5. Issues with your Operating System – Currently for users who have recently upgraded to Windows 10 from Windows 7 or 8 are having screen flickering issues due to an incompatible with the app or display driver, please check out Troubleshoot screen flickering in Windows 10.
6. Freesync Incompatibility – If you are using a graphics card without Freesync, turn off Freesync as it will conflict with your devices. Simply disable the Freesync options under the OSD menu on the monitor.
7. Troubleshoot your Monitor – Lastly, the monitor itself could be damaged or defective. We understand not all electronics are perfect and things go bad. To troubleshoot your monitor, simply try connecting the monitor to another computer and see if the problem goes away or remains. Make sure you are testing with the same resolution, refresh rate, and settings for both computers to make sure the problem is consistent.
> Why is my monitor not showing video？
1. Check your cables – In most cases, a defective cable can cause the signal to break while being transmitted across the wire and cause flickering or color distortions. Try using a different cable that you know is not defective. Additionally make sure your cable is plugged in all the way and inspect the cable for bruises, cuts, and bends in the pin.
2. Test your video ports – Another solution is to use a different port on the monitor as video port can also become defective. For example, if you are connecting using Display Port, try DVI or HDMI instead to see if the problem persists. Additionally, if you figure out the port is bad, find out if the port on the computer is bad or the monitor to narrow down the problem.
3. Check your power – Check the lights on the monitor and power adapter. Additionally, make sure everything is plugged in all the way. Loose cables can cause your monitor from working.
4. Device Compatibility – If your resolution and refresh rate is set outside the range of the monitor specification, you will have signal issues and vice versa if your monitor is set outside the range of your computer. Please check your settings using another computer or monitor to resolve your issue and reconnect the devices.

> Why is the monitor not turning on and saying no signal?
A faulty, loose, or wrongly-placed cable is one of the most common reasons for a monitor saying no signal. Here’s how to properly check your DVI, HDMI or DisplayPort cables: Unplug each cable and then replug them. Ensure each one is properly connected (fully pushed in).
1. LCD monitors generally automatically identify the signal source, if not identified, you can manually switch the input signal source (and signal line connection interface to maintain consistency).
2. when the host has both independent graphics card (generally horizontal interface) and integrated graphics card (generally vertical interface), it is recommended that the signal line to the independent graphics card.

> Is there a Protective Film or Plastic Film Was Applied to My KTC Monitor Screen that Needs to Be Peeled Off?
No, that is not a protective film, it is a special film for the panel, please DO NOT pull it off and it will disqualify you from the after-sales warranty.
> Does Temperature Affect the Performance of Computer Components?
The LCD panel works because it is supported by the work of the built-in backlight strip. These strips will emit heat, so the temperature near the back of the LCD will be relatively high, but generally will not exceed 120 °F, which will not have any effect on the performance of the machine itself, so you can use it without worry.
