23.8" 100 Hz refurbished monitor

This BenQ BL2490-R is a 23.8 inch Full HD display with a 100 Hz refresh rate and a 5 ms gray-to-gray response time. It offers 250 cd/m² brightness and a 1300:1 contrast ratio across a 16:9 panel. Wide 178-degree viewing angles and an anti-glare coating support comfortable all-day use.

Office workers and multi-monitor setups

The 100 Hz refresh rate suits general productivity, video playback and casual gaming. Tilt adjustment from -5 to +20 degrees and VESA 100 x 100 mm mounting allow flexible desk layouts. Buyers who need built-in speakers, higher brightness for bright rooms, or colour-critical accuracy should look elsewhere.

100 Hz refresh rate at 1080p

The single specification that decides fit is the 100 Hz refresh rate at 1920 x 1080 resolution over HDMI or DisplayPort. If your workflow or graphics card targets this refresh rate at Full HD, the monitor matches that requirement. If you need a different refresh rate or resolution, this panel will not meet the spec.

Questions about this item

Will the LED backlight in this BL2490-R need replacing after long daily use?

The LED backlight is rated for typical monitor lifespans; no user-replaceable lamp is specified, so plan on the panel lasting the product's useful life.

What limits continuous 100 Hz operation on this 23.8" panel first?

The 5 ms gray-to-gray response time and 250 cd/m² brightness ceiling are the primary limits during sustained 100 Hz Full HD use.

How much heat and fan noise should I expect when running this monitor all day?

No active cooling is fitted; the panel runs silently and produces only low heat typical of a 250 cd/m² LED backlight at 100 Hz.
