Question
A technician is installing a new GPU in a workstation. The system powers on, but there is no display output. The GPU is receiving power. What should be checked first?
A. Monitor cable connection
B. GPU driver installation
C. PCIe slot compatibility
D. Power supply connectors
E. BIOS display settings
Answer
C. PCIe slot compatibility
Explanation
If the GPU is powered but produces no display, the PCIe slot may not be compatible (e.g., incorrect version or insufficient lanes). Checking the slot compatibility ensures the GPU is properly connected to the motherboard.
If a newly installed GPU is receiving power but there is no display output, PCIe slot compatibility should be checked first. PCIe slots and GPUs come in different generations (e.g., PCIe 3.0, PCIe 4.0), and while they are generally backward and forward compatible, mismatches or insufficient lanes can prevent proper communication between the GPU and motherboard, resulting in no display signal.
Physical or electrical incompatibility, dust or debris in the slot, or a damaged PCIe slot can also cause this issue. Testing the GPU in another PCIe slot, verifying that the slot supports the GPU’s required version and bandwidth, and consulting the motherboard and GPU specifications are essential steps. BIOS settings related to PCIe configuration may also need to be reviewed, but slot compatibility is the primary concern when the GPU is powered but not displaying output.
