The NVIDIA GeForce 940M is a mobile graphics card that was installed in laptops and notebooks. Here is some technical information about it:

- Architecture:
The GeForce 940M is based on NVIDIA's Maxwell architecture. This architecture is designed for good performance with low power consumption.

- CUDA Cores:
The graphics card has a certain number of CUDA cores optimized for parallel processing tasks. These cores enable acceleration of calculations for graphics and non-graphics applications.

- Memory:
The GeForce 940M is equipped with dedicated GDDR5 memory. The size of the memory can vary depending on the model, but it is usually 2 GB or 4 GB. The memory offers good bandwidth and enables fast buffering of graphics data.

- Ports:
The graphics card supports various video output ports including HDMI, DisplayPort and VGA. This makes it possible to connect to external monitors and other display devices.

- Performance:
The GeForce 940M is an entry-level to mid-range graphics card intended for use in laptops and notebooks. It offers sufficient performance for everyday tasks, multimedia playback and some light games, but is not suitable for demanding 3D games or professional graphics applications.

- Power consumption and cooling:
Since this is a mobile graphics card, the GeForce 940M has been optimized for low power consumption and low heat generation. It is typically passively cooled or cooled with a small fan to keep temperatures at a safe level.

Overall, the NVIDIA GeForce 940M is a solid mobile graphics card that offers balanced performance and energy efficiency and is suitable for use in laptops and notebooks.

NVIDIA GeForce 940M/PCIe/SSE2, known issues and bugs.


The NVIDIA GeForce 940M is an older mobile GPU used in many laptops. Several known issues and bugs have been reported over time:

1. OpenGL tearing issues:
Many users report severe tearing issues when using OpenGL applications. This can be fixed by disabling VSync, but this is not ideal. The problem mainly occurs on windows with frames and can be alleviated by closing background applications such as Chrome. In some cases it helps to disable "Threaded Optimization" in the NVIDIA Control Panel.

2. Adobe Software Driver Issues:
Some users have difficulty finding the correct drivers for the GeForce 940M, especially when using Adobe Premiere Pro. It is often recommended to switch to older versions of the software as there are no studio drivers for this GPU.

3. Reliability issues with driver updates:
It has been reported that newer driver updates can sometimes cause stability issues. Users have also reported difficulty finding stable drivers for certain operating systems or software applications.

4. Access Violation Error (Segmentation Fault):
When working with certain graphics libraries, such as Raylib, memory access errors may occur due to driver issues or incompatibilities with the GeForce 940M.

If you are facing any of these issues, you can try using older driver versions or adjusting specific settings in the NVIDIA Control Panel. In the case of persistent problems, downgrading the software used can also be a solution.
