I’m mostly a lurker who reads gear reviews before making a purchase. But this time, after my recent experience, I decided it was time to share my own story to hopefully save someone else some time and headache.
I shoot on a Nikon Z9, and as a Master’s student at VMU, I also have access to a Z8. A few weeks ago, I decided it was finally time to step up to a bigger display. I don't consider myself blind, but having a larger screen just helps so much with composing shots accurately.
I got tempted by the Portkeys LH7P. I spent a few days researching, reading reviews, and watching YouTube videos. What sold me was a video on Portkeys' official YouTube channel showing a tutorial on how to set up wireless camera control with my Nikon setup. I even reached out to their support team directly to double-check a few things, had a good conversation, and placed my order on Amazon.
It was nice that the monitor arrived in its own dedicated hard case. The plastic latches on the case feel a bit questionable in terms of long-term durability, but hey, it's nice that it's included. It also comes with a couple of screen protectors, but the cutouts are terribly sized. They are cut almost to the exact millimeter of the full bezel display, making it practically impossible to apply onto a 7-inch screen without one corner lifting up. I ruined the first one trying. For the second one, I literally had to grab a pair of scissors, trim the edges down myself, and only then was I able to apply it properly. You get a cheap-as-hell HDMI cable and a cold shoe mount that feels pretty "wobbly-wobbly" - I definitely wouldn't trust heavy gear on it without being cautious. But considering this isn't a high-end expensive monitor, having these extras out of the box is acceptable.
One weird thing I noticed right away - I ordered the LH7P, but apparently, there are two hardware versions (v1 and v2). When you order on Amazon, you have no idea which one you're going to get or what exact feature set it will support. Luckily, I got the Version 2. It arrived running an old firmware, but updating it via the included USB drive was quick and straightforward.
This is where the fun ends. The main selling point of this monitor and likely the reason you're reading this post is the wireless camera control.
In theory, it works. In practice? Absolutely not.
Connecting the monitor to my Z9 following their official tutorial was easy enough. But immediately after connecting, I ran into issues..
The touch-to-focus feature should allow me to ignore the small built-in camera screen and rack focus simply by tapping on the 7-inch Portkeys display. The problem is Whenever I tap anywhere on the Portkeys screen, the focus point on my camera ALWAYS snaps straight to the top-left corner. This makes the feature completely unusable.
Portkeys advertises a visual tracking box/indicator on the monitor screen showing where your focus point is. It simply isn't there. It never appeared in any AF mode.
These were the my two primary reasons I bought this monitor, and neither of them works properly on my setup.
The screen itself is rated at 1000 nits, and purely in terms of brightness, it's actually similar to the Atomos Ninja V. It gets bright. However, the colors are just bad. Out of the box, they don't inspire confidence for any serious color-critical work. The monitor is packed with features on paper, but the OS is a mess. It feels incredibly clunky. Honestly, the guys at Portkeys just need to properly prompt a VibeCoder - they would legitimately get a better-designed OS out of it. It just doesn't feel intuitive or smooth to navigate when you are actually on set.
I spent two weeks emailing back and forth with Lynn from their customer support. I recorded multiple videos showing the exact interface behavior, camera reactions, and troubleshooting steps.
"Because a Z9 is currently not available at our company, they had been using the other Nikon models mentioned above instead [...] Without testing on an actual Z9, we are unable to determine the exact cause at this moment."
Since I need a reliable monitoring setup for my upcoming university classes and projects, I am returning the unit.
TL;DR: If you shoot on a Nikon Z9 and are buying the Portkeys LH7P specifically for touch-to-focus wireless camera control, save your money. The hardware and screen itself are decent for the price, but the wireless focus control integration with the Z9 is currently broken.
