Make full use of the usb-c interface of notebook, you might as well change a monitor first

Recently, when we introduce notebook computers, you will always hear a term: USB type-C (also referred to as usb-c), which is the following thing.

At the same time, you may also know “full usb-c” and lightning 3. At present, most of the new notebook computers on the market have added full-function usb-c interface. With Intel’s opening of lightning 3 technology and the built-in controller in its own processor, thunderbolt 3 and USB4 will gradually become a new development trend.

You also know that through the full-featured usb-c interface, laptops can connect to a variety of products, such as network cable, monitor, external keyboard and mouse, USB flash disk, etc. But you should think of another thing the first time: the docking station.

I’m not going to criticize these products because they are really practical and I use them at work.

But I don’t recommend these products if you want to achieve the effect of connecting a monitor to a laptop with a single cable, or to further advance your “wireless desktop” process.

Because many monitors have provided USB type-C interface, they can not only input video signal, but also charge the computer, and use it as a docking station.

Now that the monitor is ready for us, why buy another thing?

Product recommendation

At present, the concept of full-function USB type-C interface is still in a relatively new stage, and its ability to realize high-power power supply is closely related to the development of USB PD power supply protocol. Therefore, there are not many products supporting this function in the market, and they are all new products.

If you want to realize the related functions, the simplest way is to change a monitor first. Then enter the product recommendation section.

  • 1080p: Dell p2419hc

The first is a Dell p2419hc for office use. It has a 23.8 inch 1080p IPS panel, 1000:1 contrast and 8 bit color, and 178 & deg; viewing angle. It has joined Dell Flickr free non flash screen technology and passed the Rhine certification.

From the above parameters, Dell p2419hc is not brilliant, but this is one of the reasons I recommend it. Although 1080p resolution does look a little low now, it is mainstream enough to be compatible with computers, game consoles and mobile phones.

For example, when you want to play PS4, Xbox or switch after work, and connect your smartphone to experience “computer mode”, Dell p2419hc can meet your needs.

In terms of interface, Dell p2419hc provides HDMI, DP input and output and four USB downlink interfaces in addition to USB type-C interface (supporting 65W power supply).

That is to say, when you use the USB type-C interface, you can not only charge at the same time, but also use the monitor as a USB hub. If I can find out any problem, it may be that there is no RJ45 network interface provided. If you want to connect to the network, you need to use a converter.

However, considering the selling price of 1149 yuan (USD $164) , I think we can forget about this small problem, and the office party can consider it.

  • 2K: Dell u2520dr

If you think the 1080p is a bit outdated, or 23.8 “is a little too small, consider Dell’s & nbsp; u2520dr.

Compared with the previous product, the resolution of the Dell u2520dr & nbsp; has been upgraded to 2K (2560×1440), the panel size has reached 25 inches, and has achieved 95% dci-p3 / 99% sRGB gamut coverage and hdr400. The overall display effect has been greatly improved.

At the same time, the USB type-C of Dell u2520dr supports a charging power of 90W, which can cope with some high-performance notebook computers. In terms of interface, HDMI and DP input and output are provided, and three USB 3.0 (one of which supports bc1.2 charging function) and one USB type-C are provided for data transmission. The overall practicability is enhanced.

On the whole, the Dell u2520dr is a medium-sized and comprehensive product. The price of 2699 yuan (USD $386) is a little expensive, but considering that it can be used for several years, it is still not a loss.

  • 4K:LG 32UN880

I think if you want to experience 4K resolution, you might as well consider products over 30 inches, because the visual experience brought about by large screen + high resolution is really beyond the description of language.

When I was looking for products, this LG 32un880 attracted me. It used a 31.5-inch 4K UHD (3840×2160) @ 60Hz panel, supporting 95% dci-p3 color gamut. As for hdr10, I’d better take a look.

Compared with the parameters, the most attractive thing about this product is its ergo bracket. With the addition of this bracket, the main screen of lg32un880 can be moved in a large range, and the hollow part can also be used for line management, so as to achieve a clean and tidy desktop.

The LG 32un880 provides a USB type-C interface (supporting 60W power supply), two HDMI interfaces and a DP interface. There are two USB type-A interfaces at the slot point, which are not enough. If you are a docking station, you may need to plug another USB type-A, or you can change one of them to USB type-c. the power of USB type-C is also relatively small. It would be better if it could support 90W.

Don’t forget to confirm the specifications of the computer

So many products have been recommended in the front. If you use them with wireless charging board and other products, your wireless desktop level will definitely be higher. But before you do that, you have to make sure the specifications of your computer.

The first is whether your computer provides a full-featured usb-c interface, because not all USB type-C interfaces can support video output and charging functions. Let’s not say that some products only provide basic USB functions. Even if the lightning 3 provided by NUC I’m using cannot supply power to the machine itself, an additional DC port is needed to connect the power supply.

If the power supply supported by your monitor is less than the demand of your laptop, you will be charged while consuming power. At this time, if you are playing games or rendering video, be careful that the computer will automatically shut down.

And if you encounter AOC q2790pc, which can only provide 15W charging power, it is better to prepare a set of charger for notebook.

Finally, the full-featured usb-c has gradually become the standard configuration, so there will be more monitors to join the relevant interfaces in the future, not only more choices, but also lower premium. So if you’re not in a hurry, it’s a good choice to buy a charging dock and stick it on the back of the monitor for a while.
