Standard VGA Resolution In classic PC graphics terminology, what is the native pixel resolution commonly associated with the standard VGA display mode?

Introduction / Context:The Video Graphics Array (VGA) standard defined baseline display capabilities for early PCs and remains a reference point in troubleshooting, compatibility modes, and embedded systems. Knowing the canonical resolution helps when configuring BIOS screens, safe-mode video, and legacy hardware.

Given Data / Assumptions:

• We are referring to the standard VGA graphics mode defined by IBM and widely supported.
• “Native” here means the most recognized base graphics resolution tied to the VGA standard.
• Interlaced or extended Super VGA (SVGA) modes are excluded.

Concept / Approach:

Standard VGA provides multiple text and graphics modes. The best-known graphics mode is 640 by 480 pixels at 60 Hz, originally with a 16-color palette in the basic spec. This resolution became the de facto safe mode for boot screens and OS fallbacks because almost all hardware can generate it reliably.

Step-by-Step Solution:

Verification / Alternative check:

Motherboard BIOS and OS “VGA mode” fallbacks consistently use 640 x 480, confirming this as the accepted baseline.

Why Other Options Are Wrong:

648 x 320 and 680 x 440 are nonstandard values. 1024 x 786 is a misspelling/mistake of 1024 x 768 (SVGA), not standard VGA. “None of the above” is unnecessary since 640 x 480 is correct.

Common Pitfalls:

Confusing VGA with SVGA or with DOS game mode 320 x 200 (Mode 13h). Ensure you distinguish “standard VGA” from later extended modes.

Final Answer:

640 x 480
