Nvidia confirm 144Hz 4K G-Sync HDR screens will appear in April

Update March 22, 2018:  Nvidia have again confirmed that their 27-inch G-Sync HDR panels will start to arrive on the shelves in Q1 of this year - and that means we'll have the first batch of 16:9 panels by the end of next month.

You’re going to need one of the best graphics cards on the market to get the most out of the next generation of gaming panels.

Nvidia have been speaking about the much-delayed new gaming monitors since they first appeared on the scene at CES. CES 2017. At CES 2018 they told us the G-Sync HDR screens would start to arrive in Q1 and have reiterated that expectation at GDC this week.

There's no extra explanation about the delay, but we heard from AOC that AU Optronics had only just started to manufacture the actual panels in December last year, so it's no great surprise the actual monitors aren't appearing until April.
