‘Out of Range’ Error: Decoding Display Dilemmas in BenQ Monitors


“I’ve been experiencing an issue with my BenQ RL2450H monitor, which I purchased second-hand about a year ago. It’s connected via HDMI to the motherboard and utilizes the integrated GPU of an Intel 7700k processor. Lately, the screen has been progressively fading to white upon being turned on, requiring multiple restarts—sometimes up to ten—to rectify. Additionally, an ‘Out of range’ error occasionally appears on the On-Screen Display. Could you provide an expert analysis of what might be causing these malfunctions and suggest possible solutions?”


If you’re encountering a white screen on your BenQ RL2450H monitor, it’s important to first ensure that the monitor is properly connected. Disconnect all cables, inspect for dust or debris, and then reconnect and restart your monitor. If the issue persists, it may be related to your frame rate settings.

The ‘Out of range’ error typically indicates that the signal transmitted from your device is incompatible with the monitor’s resolution or refresh rate. To resolve this, you can try the following steps:

: This allows you to adjust the resolution to match your monitor’s capabilities.


Check Refresh Rates

: Ensure that the refresh rates of the connected devices are compatible.


Update Drivers

: Outdated drivers can often cause issues. Make sure your PC’s drivers, especially the graphics driver, are up to date.


Change Display Settings

: If you’re using a Mac, adjust the display settings accordingly.


Monitor Resolution

: Set the monitor resolution recommended by Windows, which often resolves the ‘Out of range’ error.

For the white screen issue, it’s also possible that the problem lies within the monitor itself, such as a malfunctioning backlight or internal hardware issue. In such cases, if the monitor is still under warranty, consider contacting the manufacturer for a repair or replacement. If the warranty has expired, a local repair shop might be able to diagnose and fix the problem.

Remember, when dealing with hardware issues, if you’re not comfortable performing these tasks yourself, it’s always best to seek help from a professional.
