Use this page if your monitor has a quality issue and you need warranty review, replacement review, repair support, or accessory-fault support.
Quick Answer
Warranty review usually starts with the order number, purchase channel, monitor model, serial number, and clear evidence of the problem. The faster you send complete information, the faster support can decide whether the case should continue as troubleshooting, replacement, return, refund, or another after-sales solution.
What Does KTC Warranty Review Usually Cover?
Warranty requests are usually reviewed for quality-related defects. Coverage can vary by product type, purchase channel, region, product condition, and whether the item came from an official or authorized seller.
Cases that often need extra review include:
- used or resale purchases
- purchases from third-party or unauthorized sellers
- physical damage
- problems after unsupported firmware updates or files for another model
- problems after using the wrong power adapter, cable, firmware, or accessory
If your purchase path is unusual, include that detail in the first message instead of waiting for support to ask.
How Do I Register the Extended Warranty?
KTC provides an Extended Warranty page for monitor extended-warranty registration. The page asks you to fill in your order number and email address correctly, then retain the warranty notification or activation confirmation email after submission.
Use the same email address you want associated with the extended warranty. If you later contact support about extended warranty service, contact support from the registered email address when possible.
The extended warranty page describes 30-day free return and exchange service, standard warranty service, and one year of free extended warranty for monitors after accurate registration. Some products may have different warranty periods, so check the product policy and keep your confirmation email.
What If I Do Not Receive the Extended Warranty Confirmation Email?
First check the inbox, spam, junk, promotions, or filtered folders for the email address used on the form. If you still cannot find the confirmation, contact support with:
- order number
- registered email address
- purchase channel
- monitor model
- date you submitted the extended warranty form
- screenshot of the form submission if available
How Do I Start a Warranty Request?
Send support one complete message with the following:
- order number
- purchase channel or store name
- monitor model
- clear photo of the serial-number label
- purchase date or order screenshot
- short description of the issue
- photos or video showing the problem
- troubleshooting steps already tried
If the problem involves signal, black screen, flicker, no sound, or sleep-wake behavior, include the cable type, input used, and source device model.
What Photos and Videos Should I Prepare for Warranty Support?
For most warranty cases, support can review faster when you include:
- one full photo of the monitor
- close-up photos of the affected area
- a short video showing the issue while it happens
- a photo of the monitor label
- a photo of the power adapter label if power is involved
- screenshots of display settings if the issue is related to resolution, refresh rate, or HDR
If the platform message system limits video uploads, send the order number first and ask support for the preferred upload method.
What If the Issue Is a Dead, Bright, Dark, or Stuck Pixel?
Clean the screen gently first, then take:
- one full-screen photo showing the entire panel
- close-up photos of the pixel area
- photos on solid-color backgrounds such as black, white, red, green, and blue
- the order number, model, and serial-number photo
Pixel issues are usually reviewed case by case, so clear evidence matters more than a short description like "bad pixel".
What If the Issue Is an Accessory Instead of the Panel?
If the problem involves a power adapter, cable, stand part, or remote, send a photo or short video showing the exact malfunction. Support may handle the case as accessory replacement, warranty service, or return review depending on the order and the item involved.
How Long Does Warranty Processing Take?
There is usually no fixed universal timeline. Processing can depend on:
- how complete the first message is
- whether extra troubleshooting is needed
- whether a return is required
- warehouse review time
- replacement inventory
- shipping time
If a replacement is likely, support may also ask for your shipping name, phone number, full address, and postal code.
Are KTC Warranty Replacements New or Refurbished?
Replacement handling can depend on the region, sales channel, inventory, and case type. Support will confirm the available replacement option for your order before shipment.
In some confirmed cases, support described warranty replacements as new units from warehouse inventory. Do not assume this applies to every region or case unless support confirms it in writing.
What Should I Do If the Issue Continues?
Contact support if the monitor still fails after normal troubleshooting, or if the issue clearly appears in the OSD menu, startup logo, power test, or multiple cable/device tests.
What Should I Send KTC Support?
Prepare these items before contacting support:
- order number or proof of purchase
- purchase-channel screenshot
- monitor model and serial-number photo
- photos and video of the issue
- cable, port, and source-device details if relevant
- list of troubleshooting steps already completed
