BOE showcases world’s first 600 Hz laptop gaming display

The exact specs remain shrouded in mystery, yet, in theory, the 600 Hz refresh rate would require at least a DisplayPort 2.0 connection. Knowing that Nvidia is stuck with DP 1.4 on the RTX 4000 generation and, unless BOE provides a revolutionary stream compression technology, we might have to wait a few more years to see 600 Hz on laptops.

All of these panels are fake.

Any ordinary AMOLED with a 2-3ns response can easily make fake "240" - "300Hz" IPS, which everyone is already doing.

600Hz is a response time of no more than 1.7ns on G2G/B2W. No IPS is physically capable of this. Even 2-3 ns for her in reality is beyond her strength. This is where AMOLEDs rule, although they have a lot of other drawbacks.

And the main point of a full-fledged DP 2.0 (80Gbps/72 w/o service overhead data) is support for 8k monitors up to 36-bit color depth at 60Hz. Everything else is meaningless nonsense. In TB5.0, Intel promised DP Alt Mode up to 120Gbps, but who and how will support it is still unclear.

DP2.0 in Zen4 is halved - only a miserable 40Gbps (only UHDR10 mode for one lane), which is even sharply worse than a full-fledged HDMI 2.1 c 48Gbps...

The first full-fledged videocards and integrated video chips with DP2.0 support (and apparently with TB5.0) will appear in stores no earlier than 2024. So for now, you can not twitch at all, and all the hardware purchased before the summer of 2024, in fact, will immediately become obsolete by the video interface.

Never buy a panel made by Innolux (Chi Mei).  The worst crap on the market.  AU Optronics makes slightly better screens.  BOE is the cream of the crop from China.  I don't have any experience with Samsung or LG LCD screens BTW...

@NikoB.  Just because someone else can't do it, doesn't mean China can't. 

Remember this is the country that defies nature:  Built HUGE artificial islands in the middle of the Ocean.  Built WIDE 4-lane highways in the middle of the dessert.  (Who would have thought anyone could make a highway in the middle of the dessert what with the constant sandstorm, BUT China already did that and it wasn't a small 2-lane highway but 4 or more!)

In fact, the best screens from LG in terms of sensitive eyes, there are no flickering panels. They are guaranteed to pass all tests.
BOE has flickering panels with low frequency PWM and flickering on certain patterns. The same goes for AUO and INX.

In my experience with AUOs, they usually have better viewing angles, visually, in better models than LG's. Usually higher brightness and contrast, but more problems with highlights.

BOE often have panels with multi-row backlighting, which practically eliminates glare from edge lighting. Approximately also with PLS from Samsung. And there, too, you can run into a flickering panel.

Innolux is most often harmful to the eyes, although there are normal panels.

Now there is such a mess on the market that it is already difficult to understand who really makes the panel - they can easily stick a nameplate of a famous brand on it, and inside there will be a rootless Chinese from some factory...

Unfortunately, even reviews do not guarantee anything for a specific model and even model revisions. I have already seen in practice with my own eyes that a particular laptop manufacturer can set the PWM to a low frequency in order to increase the backlight resource, make the brightness control wider and etc.

Therefore, always check the screen with your eyes when buying from an offline store. And if it is impossible to check (remote purchase), but it is possible to legally oblige the seller to give you a flicker-free screen without dead pixels, use this consumer right by clearly formalizing the product quality criteria you need. This is a problem for most people...

As I wrote above, these will be just panels in terms of response time close to conventional AMOLEDs with 2-3ms. And nothing more. Modern "240"/"300Hz" IPS panels are even close in most models, as the reviews on this site show, did not come close to the average AMOLED response, with very few exceptions.

So "600Hz" panels will only bring the average layman closer to real fast screens and nothing more. More and more in the mass case. What well. Because, I hope, there will simply be no panels left on the market with a response of more than 10ms on B2W/G2G.

This is important, but it's also important to stabilize the native contrast ratio to at least 1500:1 on matte and semi-matte panels. What they still cannot achieve even in laptop series like Lenovo Legion 7, where even the declared 1200:1 in practice, given the wild variation in batches, is not feasible.

Otherwise, everyone is waiting for microLED panels without the nasty flickering of AMOLED, but with its "infinite" contrast...
