How to troubleshoot a BenQ RL2450H monitor that fades to white and displays an “Out of range” error?

I have a BenQ RL2450H monitor that I bought second hand a year ago. It is connected to the HDMI port of the motherboard and uses the integrated graphics of the Intel 7700k processor. Lately, the monitor has been fading to white whenever I turn it on. I have to restart it multiple times until it works normally. Sometimes, it also shows an “Out of range” error on the screen. I have recorded a video of the problem here: https://vimeo.com/912495258

What could be the cause of this issue and how can I fix it?

Answer:

A BenQ RL2450H monitor is a 24-inch LED-backlit LCD monitor that offers a full HD resolution, a 16:9 aspect ratio, and a 5ms response time. It is designed for gaming and multimedia purposes, and it supports HDMI, DVI, and VGA inputs. However, some users have reported that their monitor fades to white and displays an “Out of range” error, making it unusable. This article will explain what causes this problem and how to fix it.

What causes the monitor to fade to white and display an “Out of range” error?

The most likely cause of this problem is a faulty or incompatible HDMI cable or port. The HDMI cable is responsible for transmitting the video signal from the motherboard to the monitor, and the HDMI port is where the cable is plugged in. If the cable is damaged, loose, or not compatible with the monitor or the motherboard, it can cause the monitor to lose the signal and fade to white. The “Out of range” error means that the monitor is receiving a signal that is beyond its supported resolution or refresh rate, which can also happen if the cable or the port is faulty or incompatible.

How to fix the monitor problem?

There are a few steps that you can take to fix the monitor problem. Here are some possible solutions:

• Check the HDMI cable and port. Make sure that the HDMI cable is securely connected to both the monitor and the motherboard, and that there are no visible signs of damage or wear. If possible, try using a different HDMI cable or port, or switch to a different input mode such as DVI or VGA. If the problem persists, the cable or the port may be defective and need to be replaced.
• Adjust the monitor settings. Sometimes, the monitor settings may be incorrect or incompatible with the motherboard or the integrated graphics. To access the monitor settings, press the Menu button on the monitor and use the arrow keys to navigate. Check the following settings and adjust them if needed:
• Picture Mode. This setting controls the color, contrast, and brightness of the monitor. Try selecting a different picture mode such as Standard, Movie, or Game, and see if it improves the display quality.
• Resolution. This setting controls the number of pixels that the monitor displays. The recommended resolution for the BenQ RL2450H monitor is 1920 x 1080, which is the same as the full HD resolution. Make sure that the resolution is set to this value, or lower it if the monitor cannot support it.
• Refresh Rate. This setting controls the number of times that the monitor updates the image per second. The higher the refresh rate, the smoother the motion on the screen. The BenQ RL2450H monitor supports a refresh rate of up to 60Hz, which is the standard for most monitors. Make sure that the refresh rate is set to this value, or lower it if the monitor cannot support it.
• Update the motherboard or the integrated graphics drivers. Sometimes, the problem may be caused by outdated or incompatible drivers for the motherboard or the integrated graphics. Drivers are software programs that allow the hardware components to communicate with each other and the operating system. To update the drivers, you can use the Device Manager on Windows, or visit the official websites of the motherboard or the integrated graphics manufacturers and download the latest drivers. Follow the instructions to install the drivers and restart the computer.

Conclusion

The

BenQ RL2450H monitor is a great monitor for gaming and multimedia, but it may encounter some problems such as fading to white and displaying an “Out of range” error. These problems are usually caused by a faulty or incompatible HDMI cable or port, or by incorrect or incompatible monitor settings or drivers. To fix these problems, you can try checking the HDMI cable and port, adjusting the monitor settings, or updating the motherboard or the integrated graphics drivers. If none of these solutions work, you may need to contact the BenQ customer service or a professional technician for further assistance.
