Contrast Ratio
Static contrast ratio measures how much brighter pure white is than pure black on the panel. Higher contrast means deeper blacks and more punch. Typical IPS panels reach 1000:1, VA panels 3000:1, OLED panels effectively infinite contrast.

Colour Depth
Typical: 16M (8-bit) or 1B (10-bit). More colours = smoother gradients.

Panel Type
Panel type sets the colour, contrast and viewing-angle character of the monitor. IPS = wide viewing angles, accurate colour, moderate contrast; VA = high contrast and deep blacks, narrower angles; TN = fastest response but limited angles; OLED = perfect b

Transfer Time
Pixel response time (ms) is how long a pixel needs to change colour. Lower numbers cut motion blur and ghosting in fast scenes. 1-5 ms is fine for gaming; 5-10 ms is acceptable for productivity. Manufacturers usually quote the best-case GtG number; real-w

DisplayPort Version
DisplayPort version sets max resolution and refresh. DP 1.4 = 4K at 120 Hz, 8K at 60 Hz with DSC; DP 2.1 = 4K at 240 Hz, 8K at 120 Hz. DisplayPort tends to deliver higher refresh-rate gaming-friendly modes than HDMI at the same generation.

Typical Power Draw
Typical board power (W) is the power draw under normal gaming load. Use it to estimate electricity cost and to size cooling. Peak transient spikes can be 20-30 percent higher, which is why PSU recommendations leave a buffer.
