How to Fix: Cannot set up my laptop with 2 monitors by using DualHead2Go on maximum resolution ( out of range error)
Technical issue with laptop and dual monitors setup using Matrox DualHead2Go digital edition.
📋 Table of Contents
The error 'out of range' when attempting to set up a laptop with two monitors using DualHead2Go on maximum resolution is frustrating for users who want to extend their desktop. This issue affects individuals who have laptops equipped with NVIDIA GeForcegraphics cards, such as the ASUS n56v model, and use external monitors with Matrox DualHead2Go digital edition adapters.
This problem can be resolved by following a series of steps that will guide you through troubleshooting and fixing the issue. The goal is to identify the root cause of the error and apply the appropriate solution to get your laptop's desktop extended to the desired resolution.
🔍 Why This Happens
- The primary reason for this error is due to the limitations of the Matrox DualHead2Go digital edition adapter's VGA output. The adapter's VGA input can only handle resolutions up to 1280x1024, which restricts the maximum resolution that can be displayed on both external monitors. This limitation causes the system to display an 'out of range' error when attempting to extend the desktop to a higher resolution.
- An alternative reason for this issue is related to the NVIDIA GeForce GT 740m graphics card in the laptop. The card may not support the maximum resolution required by the external monitors, leading to the same 'out of range' error.
🛠️ Step-by-Step Verified Fixes
Configuring the Matrox DualHead2Go digital edition adapter
- Step 1: Connect the DVI output from the Matrox DualHead2Go digital edition adapter to a VGA-to-DVI converter, which will allow you to connect the LG monitors with DVI inputs. This step is necessary because the Matrox adapter only has VGA input and two DVI outputs.
- Step 2: Set the video output of the laptop's graphics card to use the VGA port instead of the DVI port. You can do this by going to the Display settings in Windows 8.1, selecting the display you want to adjust, and then clicking on the 'Advanced' button. In the Advanced window, select the VGA port as the video output.
- Step 3: Adjust the resolution of the LG monitors to a lower value (e.g., 1280x1024) that is supported by the Matrox adapter's VGA output. This will allow you to extend your desktop without encountering the 'out of range' error.
Using an alternative graphics card configuration
- Step 1: Try using a different graphics card configuration on your laptop, such as using the integrated Intel HD 4000 graphics instead of the NVIDIA GeForce GT 740m. This may allow you to display higher resolutions on the external monitors.
- Step 2: If possible, update the graphics drivers for the NVIDIA GeForce GT 740m to the latest version available. Outdated drivers can cause compatibility issues with certain adapters or graphics card configurations.
💡 Conclusion
To resolve the 'out of range' error when attempting to set up a laptop with two monitors using DualHead2Go on maximum resolution, try configuring the Matrox DualHead2Go digital edition adapter by connecting it to a VGA-to-DVI converter and setting the video output to use the VGA port. Alternatively, you can try using an alternative graphics card configuration or updating the graphics drivers for the NVIDIA GeForce GT 740m. By following these steps, you should be able to extend your desktop to the desired resolution without encountering the 'out of range' error.
