- When we refer to VESA mounting points these are the four M4 size holes in the rear of a display, used to attach it to a wall bracket or desk arm. The industry standard for smaller touchscreens is that the mounting holes are at either 100 mm x 100 mm or 75 mm x 75 mm. For larger displays, for example, 32", there are 16 mounting holes, 600 mm x 200 mm at 100 mm.

- Yes. We can supply waterproof or dustproof displays.

- With a mild detergent. Note that even special wipes for touchscreen may contain corrosive agents. Unplug the power cord from the touchscreen when cleaning, for your safety.

- The LCD screen is made with high-precision technology. However, in rare instances, you may experience black points or bright points of light (red, blue, or green) which may appear constantly on the LCD screen. This is not a malfunction and is part of the LCD manufacturing process. And if you are still not satisfied with your screen due to any number of dead pixels, you can contact us for more details.

- The LCD screen is made up of millions of pixels (picture elements). A pixel defect occurs when a pixel (in red, green, or blue) stays lit or ceases to function. In practice, a defective pixel is barely visible to the naked eye. It in no way impedes the functionality of the screen. Despite our efforts to perfect the production of LCD screens, no manufacturer shall guarantee that all of its LCD panels will be free from pixel defects. Horsent will however exchange or repair the LCD screen if there are a lot more pixels than acceptable. See our policy for warranty conditions.
