Manufacturer description

The INNOCN 40C1R stretches your desktop across a 40-inch 21:9 ultrawide IPS panel running 3440 x 1440 at 144Hz over DisplayPort (100Hz on HDMI), giving you roughly 18% more viewable area than a 34-inch ultrawide. That extra horizontal room is the point: a full timeline plus preview window, three code panes side by side, or a racing sim cockpit that fills your peripheral vision without a bezel cutting through it. Color work is covered too. INNOCN ships each 40C1R with a calibration report claiming Delta-E under 2, and the panel covers 95% DCI-P3 with 1200:1 contrast, 500 nits peak brightness…
