Lenovo - ThinkVision M15

I do not recommend the asus screens with "go" in them. the inbuilt battery will not be charged by the laptop while in use I use a mix of Lenovo m14d and m15 as i wanted something lightweight

You should search for an USB-C Monitor with Power passthrough both ways. So you only need 2 USB-Cables (one can be very short), the monitor and the phone. You connect the power source to the USB-C monitor, may it be a powerbank or a power adapter. Then you connect the monitor (by the monitors other USB-C Port) with the short USB-C cable to the phone and that's it. This way your phone gets even charged while using DEX. These monitors can be somewhat hard to find. They need two USB-C ports (and nothing more). You need to read the description of the monitor carefully. The monitor must be able to power the phone, not only the other way round. I'm using a Lenovo M15 portable USBC monitor. It's relativly cheap and light.

what i use : [https://www.lenovo.com/us/en/p/accessories-and-software/monitors/office/62cauar1us](https://www.lenovo.com/us/en/p/accessories-and-software/monitors/office/62cauar1us) got it a few years ago and it has held up like a tank. the only downside is that it is 1080. if buying one today i would go for the 1440p or 4k. edit: i just noticed that i linked to the non-touchscreen version i have the touch screen version so i dont need to pack a keyboard or mouse, ( i have a mini pc & mac mini that i use often with the touchscreen for simple vjing gigs )

I have the same one and it's incredible. I love that it only needs a usb cable and it's ready to go.

I use a portable monitor from [Lenovo](https://a.co/d/6D1J9UO). It’s on the spendy side (almost at your budget). But I’ve had it for almost 3 years now and it’s never given me any problems.

Not sure they were ever seen as a gimmick. I’ve used Lenovo Think vision for over four years now. Light is a feather and goes right next to my laptop in my backpack when I travel. I use it every day when I’m on the road and out of my home office.

I have a thinkvision from my last job. Super thin and the perfect sized travel monitor. I rarely use it though for the same reason you mentioned. It only gets pulled out of my bag if something is urgent and it’d be quicker with multiple monitors

I have the same one and it works great for my needs. I like that it’s the same size as my laptop screen.

I just bought a ThinkVision m15 portable monitor and honestly, I am blown away. It is so compact and gives me so much more screen real estate when I am not at home. It folds into its own sleeve and only weights around 860 grams (1.9 lbs), so it will fit in any backpack or briefcase. If you are like me and you find yourself working while traveling all the time, it's honestly a game changer. I should have bought one years ago!

It's a 15.6 full HD IPS screen, so it does affect battery life quite a bit.

It's so convenient! I wish I bought one when it first came out!

That's a pain point. I tried to position it vertically, but the stand will only allow a fully upright position in portrait mode, which means the viewing angle is not great, especially in the lower part of the screen. There are screens from other brands that are better in portrait mode.
