This is a documented limitation with many older Acer and Gateway OEM motherboards using legacy BIOS firmware. Many modern graphics cards (such as the NVIDIA GTX 10-series, RTX-series, or AMD Radeon RX-series) require UEFI firmware to initialize properly.

Alternatively, ensure the "Launch Video OpROM" policy in your existing BIOS setup is configured correctly. Where can I find official firmware downloads?
