The resolution is incorrect while showing OEM logo during BIOS boot POST. The BOOT image appears larger than expected (resolution) and somewhat stretched to sides (wrong dimensions).
The system: Supermicro X10SLM-F with Intel Xeon Processor E3-1241 v3
Graphics GPU: Sapphire (AMD) Radeon HD6450
The image resolution (dimensions) are fine after the system is in Windows 10 mode.
Is is possible to adjust and if so how the resolution during BOOT POST could be adjusted?
