P1.538 COB LED Screen — True 4K UHD Touch Interactive Conference Wall A 6000×3375mm COB LED wall that natively resolves 3900×2194 pixels, so real 4K UHD content is displayed without scaling. Touch film, wireless casting and built-in Android control turn it into a working surface rather than a passive screen: presenters walk up, cast from a laptop or phone, annotate on the wall and switch sources in seconds.
