The Macbook Air can finally be connected to two external screens, but the performance will be cut in half!
Here's the thing, the M3 MacBook Air released a while ago supports an external dual screen display.
That's right, it's such a strange feature, it's a "heavy" update on Apple's side, and even Macbook Air won't support it until this year...
Although this is not quite a rigid need for the Air series, I can do without, you can't do without, and who doesn't want two screens at a glance.
But in fact, the MacBook Air used to support two external screens, and it was supported during this period before the M chip came out 17 years later, and even two-way 4K60.
At that time, the Thunderbolt port that came with Intel CPUs was a considerable selling point on the MacBook, with fast data transfer, strong expansion support, and large volume.
But this advantage, after the birth of the M series, disappeared, after the M chip is equipped with the hard channel limitation of the processor, the Air series can only be connected to an external screen.
Of course,There will always be a way to use it.,But it can only be through wireless screen projection.,Or interface protocol conversion plus a specific docking station, which is a slightly crooked way。。。
And even if it succeeds, the effect is not as comfortable as the native support of the dual screen, the resolution can only reach 1080p, the residual blood is 2K, and the refresh rate is not to mention.
Because of this, many friends choose to add money to the Pro series.
So, when Tony heard the news that the Air series can be connected to an external dual screen, even if it's 2024, I'm still happy, who can refuse to upgrade and change the phone for one more reason.
However, when I opened the official website, I couldn't prevent it, and it still blew to my heart.
There is a small parenthesis at the bottom of the support for dual screens, and the premise of using two screens is that the Macbook Air can only be connected to the external dual screen when it is closed.
No, it's not necessary... You're a little deliberate, even if you drop the resolution.
Besides, the MacBook Air is a fanless design, and it all relies on a metal case to dissipate heat, which is already very reluctant. The heat is all piled up inside, and the overheating is reduced in minutes.
Overseas technology blogger Max Tech proved this with a 3DMark stress test, and the Macbook Air scored 8083 points with the lid open, and the score dropped to 5916 points with the lid closed.
No matter how powerful the M3 is, it can't be so good.
After the problem appeared, the divergent brains of netizens gave several solutions, some said that one with a fish screen, one on top and one on two.
Some friends also asked, "Is it possible that I can use a magnet to make the MacBook Air think that it is in the closed state".
Eh, wait a minute. There seems to be something about this approach.
That's the case, modern laptops rely on a pair of magnetic structural devices to determine how the lid closes.
One side is equipped with a Hall sensor, and the other side is plugged with a magnet, which notifies the power management system whether the lid is closed or open through the magnetic force of contact.
Theoretically, by blinding the Hall sensor with a magnet, it is indeed possible to achieve dual-screen freedom without sacrificing performance.
But soon, some people raised their own concerns, the magnet sticks to the computer, won't it break the computer?
In fact, now there are applications of magnets in tws headphones, mobile phones, and computers, and the urban legend of magnets has long been iterated by time, and even the protagonist's CRT monitor and mechanical hard disk have basically withdrawn from the stage of history.
At that time, CRT displays, commonly known as "big butt" displays, would win this title because of the limitations of display technology, and the dielectric particles between the CRT and the phosphor screen would be magnetically disturbed, resulting in the distortion of the displayed picture, but now LCD LCDs and OLEDs are in the form of small lamp beads and will not be subject to magnetic interference.
At the same time, the mechanical hard disk is better understood, the structural parts are magnetic, the head, the head arm, the magnetic platter, it sounds inseparable from the magnetic.
When a strong magnet is very close, the magnetic head will not find the corresponding position, which will affect the normal operation.
But if you want to achieve the condition of putting a strong magnet on it, it may not be easy to break it.
In fact, Apple dared to build magnets into mobile phones and launched a series of magnetic accessories, which already explains everything.
Even the name MagSafe, Magnet Safe seems to imply that "magnetism is safe", and there is no need to talk about magnetic discoloration.
So then again, can magnets solve the MacBook Air's lid closure problem?
Unfortunately, no, magnet tricks to close the lid are useful for Windows natives, even for Macbooks older than 19 years.
However, in 19 years, Apple added an angle sensor to the hinge position to determine the angle of the lid and control the screen to turn on and off.
In other words, the magnet method can't solve the MacBook Air's lid closure and frequency reduction.
However, seeing this, it is too heartbreaking to tell you that there is no solution at all.
Today, Tony teaches you a method of extreme heat dissipation.
Fridge magnet + small fan, that's right, it's such a simple way to disappoint you.
The angle sensor is too sensitive, and the fridge magnet is already the limit.
This position really allows the MacBook Air to stay screen-off while cooling it a little bit.
As for a decent way, either wait for Apple itself to come up with a closure rule modification.
Otherwise, you can only abandon Air and choose Pro...
