Eve Devices is adamant that it should not ship its upcoming Spectrum monitor "until it is ready". To this end, it has revealed that the shipping date for its QHD/240Hz and 4K/144Hz SKUs has been pushed back to February 2021. This, apparently, will give it time to iron issues with its production out.
