Can I repair a dead pixel myself? Verified

There is a difference between a dead pixel and a stuck pixel. A stuck pixel is still coloured and might be fixed by applying light pressure exactly onto the pixel until it restores itself. A dead pixel is always black or white and can't be repaired by yourself.

How do I measure the inches of my LCD monitor? Verified

Measuring the inches on your LCD monitor is done by measuring the diagonal distance between for example the upper left corner and the lower right corner of the screen (not the edge). One inch equals 2,54 centimeter, so when you measure 99 centimeter, this means your LCD Monitor is 39 inches.

What is the contrast ratio? Verified

The contrast ratio tells how far the whitest white is from the blackest black. A contrast ratio of for example 400:1 means that the blackest black on screen is 400 times darker than the whitest white. A high contrast ratio contributes to the sharpness of the image.

What is the difference between LCD and LED? Verified

Both techniques use an LCD screen that emits no light by itself. The difference is in the lighting behind the screen. With LCD screens this is done by CCFL (cold-cathode fluorescent lamp) and LED makes use of LED lights.

How can I properly clean my LCD monitor? Verified

Turn off the television and wipe dust and dirt off the screen with a microfiber cloth. Do not use paper, this can cause scratches. Do not apply too much pressure or you might cause damage to pixels. Use a specialized detergent or make one by mixing 1 part vinegar with 1 part water. Moisten the cloth with the detergent and clean the screen. Make sure the cloth is not too wet. Remove stains by making rotating movements. Dry the screen with a second microfiber cloth to prevent stripes.
