InnoCN PU4-PRE 15,6 Inch 15K OLED Touchscreen Portable Monitor Review

InnoCN PU4-PRE 15,6 Inch 15K OLED Touchscreen Portable Monitor Review

2 minute review

It's by far the cheapest 4K OLED monitor you can buy right now; Pair it with a smart media player and you could theoretically get an OLED TV for a fraction of the cost, but we digress. The InnoCN PU15-PRE is no ordinary display, it is a powerful portable monitor intended to serve a very demanding niche. Remote creative professionals and digital nomads looking for true-to-life colors with low latency, a 6-digit contrast ratio, and the deepest blacks possible.

As such, it commands a significant premium, costing around 5 times what you'd pay for a standard Full HD non-touch USB monitor. Again, it's the Tesla X of portable monitors, a premium purchase without the hassles of money. To delve into OLED technology, check out the great guide written by our colleagues at TechRadar.

Integrated

Eight million pixels spread across a 15,6-inch panel are a treat for the eyes, and the PU15-PRE doesn't disappoint. This metal and glass tile will feel right at home among the kind of hardware you'd expect to find on a desk at a design agency. Think of Mac Pro, MacBook Pro, LaCIE storage devices, etc. a clear face cold heavy metal.

Side view

The aluminum frame blends perfectly with the glass panel; the latter is shiny and thus prone to fingerprints and reflections. The bottom bezel is thicker than the other 3 and is where most of the electronics are located.

Ports

While the speakers are located on both sides of the device, the connectors are all on the right side; there are 2 type C connectors, one mini-HDMI and 2 buttons to change the volume and OSD settings.

We like that you can turn it off, something not every portable display offers. Its dimensions, three hundred and fifty-eight x two hundred and thirty-three x six with eight mm (for a weight of nine hundred and fifty grams), make it easy to hold with one hand (but not too much).

Monitor

A brief digression here for a comparison with the 4 Sony Xperia ZXNUMX tablet, which was thinner (XNUMX mm), had a higher pixel density and ran Android. Yes, it was a tablet, but we're still stunned that absolutely no one has managed to come up with a portable screen to match the look of this seven-year-old tablet.

Support

The InnoCN comes with a protective TPU case that doubles as a kickstand. It does its job, saves the edges, but considering the cost, we would expect something a little more elegant. We'd like to see something like MountGo (see our Expresso fifteen review), a folding standing desk with rubber feet and a strong magnet that can hold the monitor in place.

There's also another alternative, an adjustable kickstand that InnoCN used on the N1F Pro, one of its cheapest 15,6-inch touchscreens.

InnoCN notes that the PU15-PRE has a refresh rate of 000 Hz, a contrast ratio of 1:1, a response time of XNUMX ms, and a brightness of XNUMX nits. The latter is what you'd expect from a mid-range laptop screen, nothing groundbreaking and certainly not one I enjoy using outdoors.

Each monitor comes with its factory color calibration report, each of which is done with a Konica-Minolta 3 meter, which examines color gamut and color difference. The display supports XNUMX% DCI-PXNUMX color gamut at high and low brightness levels, making it a great monitor for Photoshop or a secondary display for video editing.

Somehow, InnoCN engineers included a 4 mAh battery that can power the screen for up to XNUMX hours. Really, you'd be lucky to get more than a few hours at reasonable brightness, less if you use it on a radiant balcony.

Dex

The PU15-PRE charged our test smartphone, a Samsung Galaxy Note XNUMX, while displaying Samsung's understated Dex desktop interface. Since the InnoCN runs on a forty-five W (twenty V two twenty-five A) power supply, it can probably power even a small laptop (as long as it has a port-compatible power supply).

Stuck

In addition to the aforementioned cover, the monitor comes with 2 USB Type-C cables and an HDMI cable that is about XNUMX cm long. One of the Type-C cables is used for power while the other is used to connect the display to any compatible device. HDMI is used to support legacy compatibility, which means you'll lose touchscreen functionality when you use it. Ideally, one of the Type-C connectors would have been located on the other side for better cable management.

Speaking of cables, we'd like to see black or gray versions instead of white versions and probably plain instead of thick versions that aren't aesthetically pleasing. Small details that can influence first impressions.

You can use a passive stylus with the PU15-PRE, but we haven't tested one and the device is compatible with Windows and Mac. The screen isn't oleophobic, which is a disappointment, and the speakers do a decent job, but we'd wait for a better sound from a €700 monitor. InnoCN also offers a 3-year warranty when you register the product, as well as what it calls online chat support.

OSD

The OSD provides the usual functionality you'd expect, and you can use real touchscreen functionality to navigate and change settings (brightness, profiles, color temperature, font, battery capacity, etc.). We like that you can use the screen in portrait mode or upside down (the stand does not accept it either).
