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.
4000:1
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
