AOC I2771FM9 to be showcased at CES 2016

What is so interesting about this monitor you ask?

Instead of employing OLED which is proving problematic on large displays, they're going to instead use Quantum Dot. A quick read of the technology shows many of the same benefits as OLED, but due to the inorganic nature of quantum dots, should last much longer than OLED displays.

It would be mighty sweet if we could just skip OLED and move right onto this beast. :cool:

From reading the article it looks like your sadly conflating two different monitors - the 35 inch at 160Hz and Freesync is not mentioned to be using QD. The QD part refers to a separate 27 inch monitor mentioned in the article.

Off the top of my head neither seem to be that exciting - the 35 inch screen sounds like it'll be using the 2560 X 1080 VA panel we are all familiar with and the 27 inch is probably going to be 1080P as well utilising the Philips QD display they announced a while ago: http://www.tftcentral.co.uk/news_archive/33.htm#philips_276e6adsw

I hope we get some more exciting screens at CES

I edited my post to clarify that part, the quantum dot is still the most interesting bit. If they can solve the problems OLED has at large scale, then we can simply skip OLED. I'm all for gaming features, but IQ itself needs a bump up these days.

QD has been around for awhile, Samsung's JS8500+ use a form of it. Unfortunately, it really does nothing to improve the poor black levels LCDs are plagued with. Definitely not an OLED killer.

Doesn't help with viewing angles or response time either, which are both huge benefits of OLED.

The first part makes no sense to me, as QD is supposed to turn off and on when needed. Ergo, like OLED, black levels should be as high as they can go.

I think you might be getting QD mixed up with full array backlighting. QD really just improves the color gamut.

Full array backlighting (FALD) is used in some high end LCD TVs. It does improve the black levels considerably, since it's comprised of multiple LED zones (usually hundreds of them) that can be turned on/off. Still nowhere near as good as OLED though, which has full control over every pixel.

The implementation that the AOC and other currently announced 'Quantum Dot' displays use is simply an alternative backlight type. It uses a film of quantum dots to essentially replace the phosphors and diffusing layers of the backlight. The primary advantage of this is increased colour gamut with possible secondary advantages in terms of uniformity. The backlight is still controlled as a single unit (BLU), there is no zonal control or 'per pixel' stuff going on here. I'd advise reading about 'Color IQ' here, which is what is being used.
