Beautiful. Once You Get Past Frustrating Setup Issues6/8/2020 4:26:47 AM

Pros: The good: The picture is beautiful, and after 8-hours of frustrating setup and troubleshooting spread throughout the first week of ownership, they work beautifully. The price was good; I found it for about 25% less than the comparable Dell U2719DC. I’m not a graphics guy, but supposedly these are color calibrated from the factory – I can’t vouch for calibration accurateness, but the images look great on both, and the color/hue/tint/whatever of images matches on both screens if I drag an image to span both screens. The included stand supports rotating the monitors sideways if you want one long monitor for reading/coding/whatever. Also, it came with all the cables you need – USB-C to USB-C, USB-A to USB-C, Display Port to Display Port, HDMI to HDMI, and of course power. Though I understand outside of North America, it only includes the power cable.

Cons: - Getting dual monitors working via single USB-C eventually worked, but it was painful. - Provided USB-C cable is flakey - Lenovo's support is less than worthless. If you can't figure out the issue on your own, you may as well just return it. I tried first connecting the first monitor via USB-C cable to the laptop. I could see that the laptop was charging, but nothing would get displayed on the screen. After playing around with settings on both the laptop and monitor, nothing worked until I found a Microsoft article that suggested you can fix similar issues by reversing the USB-C cable. I didn’t think that would have any affect, since I was using the Lenovo provided cable, but I gave it a shot, connecting the end previously on the monitor to the laptop, and vice-versa. I was shocked to discover it worked. So that was first frustration. I’d rather they didn’t send any cables and let me go buy my own, vs sending a low-grade “one-way” cable that burnt up a couple hours of my time troubleshooting. That got everything “working” in that I could see the monitors from the laptop, but the laptop only saw the two monitors as a single external monitor, and everything displayed on the first monitor was then mirrored on the second. Also, even though Windows Display Settings couldn’t “see” two monitors, the laptop definitely knew there were two, because it showed up as two unknown displays in Device Manager. I installed the drivers from Lenovo’s website, and the correct name now shows in Device Manager, but that still didn’t help my problem. I thought the problem might be the Lenovo supplied USB-C cable wasn’t properly transmitting something since I’d read so many reviews for this monitor saying that it was a junk cable, and I'd already personally experienced one issue with it. So, I bought a Thunderbolt 3 with 40 Gbps cable thinking that would resolve my issue, but it made no difference. At this point, I tried calling Lenovo for support, but their tech support is worthless. Actually, less than worthless, and a complete waste of an hour. After going through the message system to get to a human and politely reading off my serial number and explaining what I’m trying to do, the tech would tell me that I need to be transferred to another person who will take care of me. That happened 4 times where I just went right back to the exact same queue that I was in before, same message system, etc. The fifth person listened for slightly longer and tried to really understand what was wrong before simply hanging up on me, with no pretense of trying to “transfer” me. Lenovo’s tech support is less than worthless, because they’re rude and liars, and I wasted an hour of my life talking to them and getting nothing out of it. So, I took an egg off for that. After my experience with the tech support, I was tempted to just box both monitors up and return them to Lenovo and buy the more expensive Dell. But I decided to spend another hour or two troubleshooting on my own. In the end, I found a Lenovo forum where some other monitor owner (not a Lenovo support person) mentioned needing to go through the options and make sure you turn on the option DisplayPort Daisy Chaining in the on-screen menu of monitor 1. After I did that, everything worked like a charm. For the life of me, I can’t figure out why anyone should need to enable/disable this setting. I don’t see the harm in just leaving it on all the time. The DisplayPort-out port only supports out, so why shouldn’t that port also have the Daisy Chaining feature on all the time? Another Lenovo frustration.

Overall Review: I bought 2 of these monitors specifically so I could have dual screens, and power the laptop, and USB ports for keyboard + mouse, etc., all connected by a single USB-C cable to my Surface Laptop 3. It took a bit of work, but I can confirm it does all work perfectly. I wanted to share my issues in case anyone else is having similar problems. My setup: 15” Microsoft Surface Laptop 3 (Intel version) connected via USB-C to Monitor 1. Then, a Display Port from the Display Port out of Monitor 1 to DisplayPort In of Monitor 2. Enable DP Daisy Chain in Monitor 1's OSD. DisplayPort-Out is the one with the arrow by it: DP->
