It's automatic as well but for some reason it gives you "new to OCN".
Monitor panels are very very slow to progress, it was quite similar before LCD as well with CRTs if not worse really.
Small mobile devices panels advance fast and well, so do large TVs, they get much more marketing and sometimes sales than monitor sized panels.
Corporations don't want to invest into making LCD obsolete nor improving it too much, they struggle with production quality big time and can't even deal with that yet. They love to hunt numbers such as resolution, max brightness, advertised low response times but are not interested in improving the technology itself in a meaningful way, such as resolving their endless production issues, better contrast, removing glow with a filter, making better frames to avoid BLB, get dust free assembly lines to avoid the endless dust stuck inside panel issues, better response times and faster control boards to offer higher refresh rates while not butchering such pursuit with crazy ghosting, artifact lines, inversion issues, ...
They try, in a way, they announce a panel to monitor maker, they then jump on the hype train and announce a monitor no has every seen yet despite the fact that it will take a year before they get any panels if at all and then another year for them to make the monitor... yeah they can be that slow unlike making other products.
Yeah they can probably spit out a few engineering samples at high cost but it takes time to make it viable for mass production, iron out as many kinks as possible and even then as you can see from monitors you buy the panels often suffer issues anyway.
The industry has not adapted to a fast production, it takes them ages to go from "paper to product in stores".
They don't have anything else much so they keep touting and teasing with unreleased engineering samples for years.
