Dell U4320Q 43 inch 4K UHD Computer Monitor
The Dell UltraSharp U4320Q is a 43-inch (42.5" viewable) professional 4K UHD computer monitor built around an IPS LED-backlit panel running at 3840 x 2160 resolution and a 60 Hz refresh rate.
The display covers 96% sRGB and is factory calibrated to Delta-E less than 2 at 99% sRGB, giving accurate, consistent colour for design, editing and large-canvas productivity work.
Brightness is rated at 350 cd/m2 with a 1000:1 contrast ratio, and the screen carries a flicker-free, low-blue-light certification.
The thin-bezel chassis weighs around 13.2 kg and supports both 100x100 and 200x200 VESA mounting.
Connectivity is broad: 2 x HDMI 2.0, 2 x DisplayPort 1.4, 1 x USB-C upstream with up to 90 W power delivery, 1 x USB-C downstream and 3 x USB-A 3.0 ports, plus audio out.
Picture-by-Picture and Picture-in-Picture let users drive content from up to four sources at once. Integrated 2 x 8 W speakers cover basic audio without extra hardware.
The stand offers tilt, swivel and height adjustment.
For Sri Lankan event, AV and corporate users, the U4320Q suits control-room dashboards, live-stream and multi-camera monitoring, exhibition booths, retail showrooms, conference rooms, video-conferencing podiums, design studios and digital signage.
The 43-inch 4K canvas works well as a large desktop replacement for engineering or finance workstations, as a sports event scoreboard display, or as a high-resolution preview screen for production crews.
