Bought this monitor to be used side by side with my Dell Ultrasharp FHD one. The 4K resolution is so much better for viewing text at work, not to mention getting the best out of 4K videos/movies. Out of box, the color is so much more vibrant and accurate compared to my older monitor. That motived me to go through my photo collection again and I got better memory about the trips I went for taking those photos. My measurements with a Spyder Pro indicate 100% coverage for Adobe RGB color gamut, matching the specifications. The thunderbolt connection also works great with my laptop, and I can actually use the one-cable solution without worry about balancing bandwidths for video and data signals. I really believe that Thunderbolt or USB C 4 IS required for a 4K monitor ... MoreBought this monitor to be used side by side with my Dell Ultrasharp FHD one.

I want a screen that would replace the laptop + extra screen setup that I've used for the past few years. I want really high definition. I want zero eyestrain images and text from daylight to night time use. I want good screen adjustment both vertically and on a horizontal axis (for use standing and sitting). I want minimum wires across my desk. I get all of these benefits from the ThinkVision P27u20. I purchased following a review in PC Pro magazine who rate this highly at just under £500. That was my budget and so it went into my shortlist. The first thing you notice is the seriously well engineered stand that's included. By laying the box on the floor and opening it up there you can attach the stand to the base, clip the stand into the screen and then lift the ... MoreI want a screen that would replace the laptop + extra screen setup that I've used for the past few years. I want really high definition. I want zero eyestrain images and text from daylight to night time use.

I purchased following a review in PC Pro magazine who rate this highly at just under £500. That was my budget and so it went into my shortlist. The first thing you notice is the seriously well engineered stand that's included. By laying the box on the floor and opening it up there you can attach the stand to the base, clip the stand into the screen and then lift the screen, attached to the base, easily. Once attached the weight of the screen and stiffness of the stand are perfectly engineered to set it up on your desk/table without fuss. While observing that the screen display must be treated with care, the assembled unit is strong and firm. There are little feet on the base that ensure the assembly doesn't slide around. very good. Now to connect to my computer. I no longer need a laptop, so recently bought a "mini" PC (so much power for the money but do research customer feedback and reviews). The "getting started" document was minimal and hard to read. I ended up going on line to read the larger manual there first. The P27u-20 has 3 ways of connecting: HDMI, Displayport and Thunderbolt. Since Thunderbolt uses a USB "C" plug design I though the USB "C" socket on my Windows PC would work...er "No". I've learned something then - but if a Windows, rather than new Macbook user, the associated 2 sockets on the screen may not be much use. HDMI and DisplayPort definitely do work without issue. Also on initial switch on, the definition was awful, less than HD. I despair I went to the Lenovo site and downloaded a few drivers that seemed appropriate..and after restarting the PC a few times the appropriate drivers automatically loaded (Win 11) so my initial disappointment evaporated. I still think that better documentation could have prepared me for this. The P27u-20 is a sophisticated device and did not behave in a "plug & play" manner. Not at first anyway. Once up and running the first noticeable benefit is the super screen clarity. I can now display 2 full window displays side by side, sufficient to write on one and simultaneously research in another, which is how I like to work. I've not explored the full colours capability yet, as mentioned this is a sophisticated device and I am sure that it has much more capability than I am using. The user manual is quite large but quite technical. I think there is scope for a document covering typical use cases and how to set-up the screen for them. Here's an early example - I'm very serious about music and sometimes like to play music from my PC without having to switch on my "studio monitors". The P27u-20 has speakers, not large ones, but the 2 X 2 watts should be adequate. At first I was hugely disappointed ..the sound was a whisper. However investigation of the screen menu (not the PC sound controls), revealed an internal volume control. Set that higher than the 50% default setting and the display sound is perfectly good for use with Youtube and Facebook. A word about the sockets. The P27u-20 is advertised as a "Docking" screen. Yes it has 2 standard USB sockets, a NW RJ45 and a couple of Thunderbolts. But these sockets are not easily accessible once the screen is set up for use...e.g. certainly not for the temporary plugging in of say a USB storage drive. In practice you'll still need a PC with sockets or an outboard docking station that you can get at. So while the docking functionality of the P27u-20 is useful, its NOT THAT useful. In summary then, am I pleased that I bought the P27u-20? YES, I am. Now its all working for my needs above I'm happy that they have been met. Would I pay more than the £500 (just under) I paid for it? NO. There are plenty of 4K 27" screens at this price point to choose from. I note that Lenovo have raised the price to £700+ at the moment, but I suspect this will come down again and the rise is just so they can lower it again to show a discount for "Black Friday" (ever the cynic). It may be that the screen has features that I'm not using that make it worth a higher price. Maybe, but not to me. If that's that case then these should feature in their marketing. Right now it doesn't stand out as being worth the extra...but it IS a good screen for a home/office and I'm glad I bought it (at under £500).

First, the contras, that may not be relevant for you.- If the KVM is important to you, look somewhere else. The KVM of this monitor is quirky when it works. Most times it doesn't work. It is uncapable of waking up a PC that was sleeping, so you need to wake up the PC, then switch to it.- Controls are outdated. Modern monitors come with a joystick to operate the OSD, but this still uses the row of buttons.- PC software only works in Windows 10, not Windows 11.- Black is not very dark.- In hopes to improve the KVM, I searched for a firmware update. There's no tool available, meaning that Lenovo does not plan to update its firmware. This may change in the future.Now the pros:- Excellent color! Delta E smaller than 0.5, which is great. Means that the color ... MoreFirst, the contras, that may not be relevant for you.- If the KVM is important to you, look somewhere else. The KVM of this monitor is quirky when it works.

Means that the color presented on the screen is very close to the color sent by the PC.- Impressive color space. 100% sRGB and more than 95% AdobeRGB and DCI-P3.- Very good number of ports. I removed a number of cables, KVM and USB hubs when I installed this monitor.
