Explore the New 21 inch Arcooda LCD Monitor - Low Display Lag and Stunning Clarity

  • 4th April, 2026

Our new release 21.3inch LCD monitor offers a premium solution for your 4:3 aspect ratio uses. From digital display wall mount with 500nits and 1800:1 contrast, to desktop use with HDMI and DisplayPort inputs, to 1.7ms low display lag for retro and arcade gaming. The long awaited replacement for our 20.1inch 4:3 has arrived.

Bigger is not necessarily better, our 21.3inch shows more information in a smaller footprint and perfect as a secondary working monitor with more vertical screen space. Whether you're reading long documents, coding, or working with spreadsheets, less scrolling means more productivity and better concentration. Our 21.3-inch 4:3 monitor closely matches the proportions of A4 and letter-sized documents, making it ideal for editing and reviewing.

The 21.3inch LCD monitor has higher specifications than our flagship 20.1inch 4:3 monitor, with more video resolutions supported (160+), higher brightness levels, higher contrast levels, large screen size, more video input options, more mounting option and more video menu options. Some specifications are below;

• 21.3inch 4:3 Ratio
• IPS Panel / LED
• 500nit brightness
• 1800:1 contrast
• Native 15khz to 1600x1200
• VGA + DVI + HDMI + DisplayPort Inputs
• 10watt audio Output
• Remote control
• Display Lag: Leo Bodnar 1.7ms, Time Sleuth 1.7ms

Connectivity meets flexibility, our new monitor supports RGB (both combined sync and separate H+V), RGB sync on green, VGA, DVI, HDMI and DisplayPort. With multiple mounting points including VESA, and angle brackets (included), mounting into any application is easy.

If you are a retro gamer, or traditional arcade machine operator, our 21.3inch is truly a plug and play "arcade monitor". The firmware has been tuned on real arcade game boards and supports 15khz natively. Use the RGB color potentiometer board for plug and play arcade options, or connect your PC/retro products via VGA directly into our 21.3inch 4:3 ratio monitor for very low display lag gaming (1.7ms).
