☑ Contrast Ratio: Most LCD monitors have a contrast
ratio between 1000:1 and 3000:1, which is sufficient for everyday
work. Higher-end monitors can offer ratios of 4000:1
or more, especially in the case of OLED displays.
☑ Brightness: It is measured in candelas per square
meter (cd/m²), typically ranges from 200 to 500
cd/m² for standard LCDs, while high-end models
can exceed 1000 cd/m². Higher brightness is
particularly useful in well-lit environments
or for HDR content.
☑ Color Bit Depth and HDR: Modern
screens can display millions of colours, which
is generally enough to represent the full range
of natural hues. However, more important than
quantity is color accuracy, how faithfully a monitor
reproduces those colours. A newer feature,
HDR (High Dynamic Range), enhances realism
by improving contrast and color vibrancy,
especially in highlights and shadows.
☑ Refresh Rate: It refers to how many times per
second the image on the screen is updated,
measured in hertz (Hz). For basic office work,
60Hz is typically sufficient. However, for tasks
involving fast motion, such as video editing,
gaming, or 3D rendering, higher refresh rates
like 100Hz, 144Hz, or more, offer smoother visuals.
☑ Response time: How quickly a pixel changes
color, also affects performance. For general use,
8ms is adequate. For demanding tasks or gaming,
2ms to 5ms is better, and 1ms is ideal for
high-performance gaming.
🏁 Pixel Pitch: Often overlooked, pixel
pitch, is the centre-to-centre
distance between two adjacent pixels, each
consisting of a group of sub-pixels (RGB).
Lower pixel pitch is crucial for clarity, especially at
typical viewing distances of around 45 cm.
Lower pixel pitch means higher pixel density
and therefore sharper images. A standard pixel
pitch is 0.28 mm, while high-resolution monitors
can have 0.22 mm or even 0.16 mm. Pixel pitch is
directly related to PPI (Pixels Per Inch).
☑ Connectivity: Most modern LCD monitors
support HDMI connections (versions 1.4, 2.0, or
2.1), with newer versions offering support for
higher resolutions and refresh rates. Another
common option is DisplayPort, which is often
preferred for high-performance displays due to
better support for high refresh rates and resolutions. |
