Ultra-slim GR16HQ portable OLED monitor with a lightweight aluminium body

So, this is a lightweight aluminum body measuring just 3 and 1/2 mil at its thinnest point, and weighing around 720 g. Extremely easy to slide into a bag.

GR16HQ 16:10 aspect ratio monitor, ideal for Steam Deck connection and productivity work with extra vertical screen space

The aspect ratio on the screen is 16 by 10. Perfect if you fancy hooking up your Steam Deck to it. The 16 by 10 really helps when it comes to productivity and desktop work cuz we get a bit more vertical space than we do with a 16:9 ratio.

USB-C, Mini HDMI, and Built-in Speakers

GR16HQ portable monitor ports: 2 full-featured USB-C ports for power and video over one cable, plus 1 mini HDMI port

So, connectivity-wise, we have two Type-C USB ports, fully featured for power and video over a single cable. We have one mini HDMI.

So, the HDMI supports up to 3K at 75 Hz or 1440p at 120 Hz, while Type-C delivers a full 3K 120-Hz experience.

OLED Picture Quality: Contrast, Colors, and Brightness

Deep Blacks and High Contrast with OLED

GR16HQ OLED monitor with self-lit pixels, delivering deep infinite blacks with no backlight bleed

Now, I've tried LCD portable monitors, and yes, it was good, but once you go OLED, you never really want to go back. With OLED, there's a huge difference. True self-lit pixels, which means deep infinite blacks with no backlight bleed.

100% DCI-P3 Color Gamut and 500-Nit Peak Brightness

GR16HQ with 100% DCI-P3 colour space for vivid media and accurate photo/video editing, 500 nits peak brightness and a glass screen for enhanced clarity

The GR16HQ has a 100% DCI-P3 color space, making it punchy for videos media, and accurate for photo or video editing workflows.

With a peak brightness of up to 500 nits, it is usable in well-lit rooms, and I found that it works really well in our living room. The glass screen does really help with the pop and clarity of colors.

Gaming Performance: Using the GR16HQ with Steam Deck

Honestly, using the Steam Deck with this monitor has been a joy. First game I tried on it was Vice City, and oh my days, Vice City remastered.

Stunning OLED gaming visuals on GR16HQ with zero motion blur and no ghosting during gameplay

Yeah, it gets a bit of flack for the game itself, but the visuals on this OLED screen were amazing. There was zero motion blur or ghosting. I was so impressed by it.

UPERFECT GR16HQ Pros and Cons

Pros: OLED Visuals, Smooth Performance, and Lightweight Design

Key benefits of GR16HQ 3K portable OLED monitor: infinite contrast, 1ms response, slim build, VESA mounting points and 16:10 productivity ratio

So, what are the pros of this lovely 3K portable OLED monitor? Well, stunning visuals with infinite contrast. You've got a lovely smooth refresh rate and an ultra-fast 1 ms refresh time.

It's thin, it's lightweight, and features VESA mounting points. Also, it's 16x10 ratio, which is great for productivity.

Cons: Glossy Reflections, HDMI Limitations, and Power Consumption

But, there are going to be some trade-offs. It's got glossy reflections in bright or outdoor light, as you could probably see in this video, being able to see my laptop screen in the reflection.

HDMI connection is limited to 2K at 120 Hz or 3K 75 Hz. And that is down to bandwidth limit. If you want full 3K 120 Hz, then you're going to have to use USB-C. And it has got higher power consumption, typical for some OLEDs.

Final Verdict: Is the UPERFECT GR16HQ Right for Gaming and Work?

So, if you're looking for a top-tier portable setup for gaming, creative work, or a sleek second screen that delivers true OLED blacks and high frame rates, then UPERFECT GR16HQ  is one of the most feature-packed portable displays available.
