If your Samsung Monitor’s display is visible but is not displaying correctly, then the problem may arise from the graphics card.

Importance of Driver

If you wonder what’s the driver’s connection to your monitor is, then here’s the answers.

Drivers are tiny programs that your computer’s operating system uses in order to transmit information with the Graphics Card, Monitor, Storage Devices, and Printer.

Without updating the driver, it may become inefficient in transmitting data to the devices, including your monitor.

2. Tilt problem

Tiltable Samsung Monitors such as the LU28R550 may be innovative ergonomic designs for monitors. However, this may become a hassle for the user when a tilt problem arises.

Different factors could affect your monitor’s tilt problems, and these are listed below.

Loosened Hinge

The hinge is one of the reasons why your monitor can be tilted forward or backwards smoothly.

However, they loosen once used frequently or poorly used. But don’t you worry because hinges are simple to fix.

One of the things you can do is to tighten them. But if the screws are not visible, then fixing it yourself might not be enough.

In this situation, it’s best to take your monitor on a trip down the tech specialist as this reduces the further problems that may arise.

Damaged Hinge

A loosened Hinge is just a simple problem, but it may lead to more complicated issues once a hinge is damaged.

Since the monitor is tiltable, its neck is attached to a hinge, and once it becomes faulty, the monitor may collapse and break.
