Colors are incredibly rich for a touch panel. The 5000:1 contrast ratio makes our design presentations look stunning. BBE customer service was also very helpful in explaining the VESA wall mount options before purchase. ✨

Excellent for our office meetings. Delivery was fast and the 50-point touch is very responsive. Android 14 makes it easy to use apps directly. Highly recommended for business use.
