CrowView: A clamp-on, portable second laptop display

(2023/09/05)


CrowView is a 14-inch USB-C monitor with a cunning folding stand-cum-clamp system which allows it to attach to most sizes of laptop for some more pixels on the move.

[1]

The [2]CrowView is a portable display, from the same company as the [3]CrowPi 2 and [4]CrowPi-L Raspberry Pi-powered laptops. As a lightweight 14 inch, 1920×1080 LCD, at first glance it is not very different from another laptop auxiliary screen, the Lenovo Thinkvision M14, which [5]The Reg reviewed in 2019 : same size, same resolution, to start with. The Crowview scores over the older device in several respects, though. First, it is slightly cheaper (although it doesn't have the words DON'T PANIC on the cover, or indeed, a cover at all). It is set to sell for $179 (£142), although pre-launch backers can get it discounted down to about $115.

Secondly, it also has a mini-HDMI port, for devices that can't drive a display over USB-C. And it has a headphone socket: although the device itself is silent, it can relay sound to wired headphones. At 400 nits, it is brighter than the Lenovo, too, and it comes with a supplementary power supply, for HDMI use or if your USB ports don't offer enough juice.

The really nifty feature, though, is its folding stand. This reminds us of a smarter version of a universal mount for attaching a smartphone to a car's dashboard, but it's more versatile. The Crowview can stand up on its own, either in landscape or portrait orientation, but the stand can also clamp also the lid of laptops from 13 to 16.5 inches, and hold the Crowview in three different landscape positions. The most obviously useful are either on the left or the right, where the hinge can flex 230° — and there's a fold-out kickstand to support this. Saying that, we tested it, and you can use the device this way on your lap. Apparently, it can also attach magnetically but we don't have anything suitable to test that.

[6]

The third mode is facing directly backwards, as what the company calls a face-to-face display, allowing you to show or present from the back of your laptop's lid. Finally, the stand folds flat across the face of the device, to offer some protection in transit. We carried it to Prague and back, across four flights, when travelling hand-luggage only, with no problem.

[7]

It draws 4.8 Watts of power in use, and is 13¾×8½ inches (35×21.7cm) in size. The screen is 1cm thick, and so is the stand, so folded it's 2.1cm (about ¾ inch) thick. It weighs some 1¾lb (800g), so it is heavier than the Lenovo screen, but that's the cost of the cunning clamp. We tested it with the latest versions of Windows, Ubuntu, macOS and the systemd-free MX Linux, and all worked perfectly, with no additional drivers or configuration needed.

Although it's still in the crowd-funding stage [8]on Kickstarter , it has already exceeded its goal by nearly five times. The Reg FOSS Desk is rather impressed by the device and can see it proving very useful when on the move: we prefer two smaller displays to one bigger one, anyway.

The one orientation we'd like that it can't do is be positioned above your built-in display, but we can't see how Elecrow could implement that without considerable extra thickness.

"Portable Display" means what?

badflorist

This is a mount with a random monitor. These have been 3D printable for a long time.

With no effort: a mount [1]on top or [2]to the side

A couple years ago I remixed a Surface Pro mount and while it worked, the Surface was too heavy and caused my 14" 2-in-1 to balance like a seesaw so... it was in theory cool

Surprising to see how close that second link ( to the side) looks like the CrowView version ;-)

Re: "Portable Display" means what?

Yeh they all look very similar with hinges and swivels and what not. They're also easily printable as they don't require many Z layers or overhangs. You don't even really need a flat print bed because the frames can twist a little. In other words, they're easy and quick prints.

A random *USB-C powered* monitor.

Wouldn't your device need a 2nd power brick for the display, or at the least, two cables, one for display signal and one into a USB port for power?

I am not saying it is not doable. But this device is *cheap*, it's *light*, it uses just one cable for signal and power in one, it's near-universal and it's portable.

Re: "Portable Display" means what?

Mr Humbug

USB-C powered portable monitors exist from elsewhere and have done for a while. Last year I bought a device branded Arzopa E1 Extreme. It's 15", 4K and either uses one USB-C from a laptop or a mini HDMI and a 5V USB-C power supply. I've not checked, but I think it may well use more than 4W.

The only issue I have with it is that it won't do 4K at 30Hz, it's 4K at 60Hz or QHD at 30Hz. On the other hand, 4K on 15" is a little small anyway.

The clamp-on stand is appealing, but not sure my 13" laptop would balance with the extra weight

Was it usable as the display for a RaspberryPi?

Martin Gregorie

This would seem to be an obvious display for use with a RaspberryPI for any task requiring a laptop-size display, so why no report about how well this combo works?

Re: Was it usable as the display for a RaspberryPi?

badflorist

Depends on how you want to interface with it and what you mean by "RaspberryPI" (you don't mean "Pico" right?)

For a 4B, I picked this up "open box" for $100usd on ebay: [1]13.3inch oled . However, while it says it's DCC controlable, I couldn't get it to work so it's HDMI only for my 4B :-/. Other screens, by waveshare or whoever usually do work with DCC and not just the power hungry 4B.

Um. To be honest, my Pi 400 lives plugged into an HDMI display and I am very happy with it. I don't feel any need.

I think a Pi's little PSU would struggle to power a Crowview, and I don't know if the Pi can drive a USB display. It doesn't seem very ideal to me.

I don't have any Pis running the Pi OS. All mine run other Linuxes or RISC OS. ;-) I am confident RISC OS and Ubuntu Server can't drive a USB display and I have my doubts about Lubuntu or OpenElec.

Be braver -- you can't cross a chasm in two small jumps.
