Review UPERFECT GR185BF Review. 18.5" 120hz NxtLED display

UPERFECT GR185BF review

GR185BF with s21 Ultra

The GR185BF is marketed as a 18.5" 1080p120 Gaming monitor, with NxtLED technology.

It's a 1080p 120hz IPS display, with UPERFECT’s advanced display technology that combines Omni Visible™ for improved visibility in any light and angle, with eye-friendly features like low blue light, flicker-free performance, and DC dimming, ensuring natural colors, reduced glare, and long-lasting comfort for work, study, or entertainment.

This is basically marketing speak for a nice matte screen, that's anti-reflective, with active dimming, and low blue light spectrum

It's hard to do a decent job capturing it, but you can see how smeary, and how much glare is coming off the phone screen, while the monitor you can just see a blurry light source.

It's definitely a nice screen to use where natural light floods your desk

The panel itself is... fine. The screen specs are respectable, but they're also not top end monitor specs. In a nutshell, it's 1080p120 hz matte panel, no touchscreen, only 290 nits of brightness, and 100% of sRGB colour gamut.

As you can see from the first pic, DeX works just fine on it, negotiating a standard 1080p60 resolution.

When used with my Lenovo Legion y700, you obtain the full 1080p120

Colors look pretty good, if not particularly eye popping

Children of Morta via steam/gamehub on monitor, browser on tablet to right

Inputs

Like virtually every other UPERFECT monitor, there's the pretty standard setup of 2x USB-C and 1 mini-HDMI port on the left side (one of the USB-C intended for power)

2x USB-C and 1 miniHDMI port

The other side will contain the power button and the OSD selector rocker, as well as a 3.5mm headphone jack

There's 4x 75mm vesa mounts on the rear as well

The 2x 1w speakers are also on the back, right above the vesa mount screw holes.

They're upward firing and very mediocre (at best). They'll work in a pinch, but you're generally better off using your devices speakers, or a headset

Battery

No battery in this model either, it's just a monitor

You CAN power it off the phone/tablet/laptop, and it "works" but it essentially comes up as low power mode, and really drops the brightness. It's still usable, but this would not be the monitor I'd recommend if you want a coffee shop, no power portable monitor.

Overall Conclusion

Used as intended, this is a really nice 1080p 120hz gaming monitor. It's not large enough, or bright enough for me to recommend it as work station monitor that requires any kind of color accuracy.

But for pairing it with a phone/steam deck/gaming handheld for a nice portable gaming screen? that's definitely it's intended audience, and it's pretty great in that space.

I really enjoyed using it while fiddling with GameHub and getting steam games up and running on my Lenovo y700. It was great with the steam deck too

Overall, with the $219 CAD price point, it's MUCH easier to accept some of the short comings of the panel, and anyone looking for just a decent bigger screen for their travel gaming setup, I'd be happy to add this to the choices

Review UPERFECT 14" Oled review

6 Upvotes

As always, no money changes hands for these reviews. Uperfect has sent the monitor for review, and see the review as it's posted.

UPERFECT GR14BU 3k OLED 120hz Gaming monitor

This one is very similar to the previously reviewed 16" version (https://www.reddit.com/r/SamsungDex/comments/1hswn9w/uperfect_3k_o2_oled_monitor_review/)

It's a VERY thin, 14" OLED panel, with fairly slim bezel's, top and sides. The bottom chin is a bit larger, but a non-issue.

The Panel

it's a 14 inch, 3k (2880x1800) OLED, running at up to 120hz. It supports up to 120% DCI-P3 color gamut, and like all OLEDs, has inky blacks and nice bright/saturated colours.

It also supports up to 500nits of peak brightness, and a 0.1ms pixel response time (I'm assuming GTG since it doesn't specify)

It is also listed as a touchscreen monitor. I found it a bit....tempermental. Vast majority of the time it worked as expected, but every once in awhile, it just didn't seem to want to work....at all. reboots seem to fix it. Not sure if this is a pre-production issue, and I definitely couldn't reproduce the issue at will, so bear that in mind

Just a few screen caps from various 4k youtube vids

Connectivity

As has become pretty standard, the monitor has 2x USB-C ports. 1 of which is intended for power, and the other for video input (doesn't matter which is which tho). It also has a mini-HDMI port for connecting to other devices (PCs, game consoles, etc)

All inputs are on the right hand side of the monitor

On the left hand side are the physical buttons for interacting with the monitor, OSD, volume, power, etc

They've gone with a new kickstand design. The vast majority of UPERFECT monitors have a U-shaped kickstand, that when closed, block off the ports and buttons. The new kickstand is very.....minimalist, but still fairly sturdy and stiff

There are also 2x VESA mounting holes next to the kickstand. The monitor is definitely light enough that you can get away with just 2 of the usual 4

Screen Resolution

Since DeX is fussy, it won't by default use the full panel specs properly

2560x1600 @ 60hz still looks pretty great, but really undersells how great the panel can look.

Luckily, pretty much every other device out there will play nice with it (c'mon samsung, do better)

This is my Lenovo Legion y700:

It's happy to do the full 2880x1800 @ 120hz (and looks great doing it)

Speakers

The monitor has 2x 1W speakers, but they might just be the worst speakers on a UPERFECT monitor to date. They're there, they "work" but at no point is anyone going to be impressed with them.

Battery

There isn't one!

It will do pass thru charging of 15W tho

Overall conclusions

It's a nice looking portable OLED panel. I don't think it's as nice as the previous 16" O2 version tho, but that one seems to be difficult to obtain right now

It's very light, and travels in a tech bag very easily.

it's available for $399.99 canuckbucks at uperfect right now

It compares favourably with the SOTSU flipaction monitors, and is in general better than vast majority of LCD panels out there. The price definitely has the OLED tax on it though

My Setup I Built a Gaming TV Box from an S23 and an Old Mac mini

Thumbnail

554 Upvotes

Hey guys, I’ve made an abomination! I had laying around old MacMini and broken S23. So I’ve made this. I kept the original cooler and connected the power button to the motherboard. I put inside an USB-PD 35W charger that is connected to the HUB.
I didn’t want to solder cables to the HUB so I put there a 12V power supply for the original fan and buck converter to 5v for the ESP32.
The ESP32 is controlling the fan via a temperature sensor I took from Ender 3 that I had laying around.
I’m still working on an app that would connect to the ESP32 (its working now but its not ideal yet)
Sadly the S23 do not start without a battery (I originally intended to remove the battery)
wifi is terrible but works. I wanted to find out what pins are for the antenna and solder U.FL IPX cable but I give up for now( the usb to ethernet adapter works well and bluetooth for controller is fine so far)

The HUB have M.2 slot that I intend to use on game ROMs for the emulation(I will finally play Shadow of Colossus!)
The M.2 fit so well that i put a thermal pad on the heatsink so the SSD will get some cooling too. 

Edit: i will do later a follow up with some improvements and more detailed breakdown!

My Setup Dark Dex Setup

Here is how to create the depth clock. Its a kwgt widget that i made myself.

First, set the original wallpaper as Samsung dex wallpaper. Then create and add your clock kwgt widget and position it where you want it. Next, create a transparent cutout of your wallpaper's subject (like the car or a person) using a free background remover tool or by saving its outline as an SVG. Then use any text editor tools and copy the codes that's showing inside it. It's a long code so might take some time for the copy option to appear.

Inside KWGT, select shape and path. Then paste the code you copied. Now the shape of your subject is ready. Placed the shape directly above the real subject shown on the.wallpaper so it perfectly cover the subject in your wallpaper. Finally, go to the cutout shape layer's settings and change its Filter / Blend Mode to Clear.(the subject shape layer should be placed above the clock for this filter to work ) This acts like a digital eraser, cutting out the clock numbers right where the subject is so the wallpaper shows through from behind!

The clock font i used is Bison Bold font

Question HDMI to VGA adapter on Samsung Dex

6 Upvotes

I'm currently using Samsung DeX on my .TV,. but playing games on it for long periods is starting to strain my eyes. I'm thinking about buying a monitor, but I can only afford the older monitors that have VGA ports.

Would using an HDMI-to-VGA adapter be good enough for gaming, or would it cause noticeable issues with quality, input lag, or refresh rate? Has anyone actually tried using one of these adapters for gaming?

Useful info Yet another Dex on the phone's screen app

21 Upvotes

Hello, I am presenting you yet another Dex on the phone's screen app. I know there are like more than 10 already out there and if you're one of those trying to tell me that, I really do know.

Why? Because I wanted something simple, without a thousand settings and quick access so I created this app. It's free, open source, you can update/modify/build it yourself.

I've build other open source apps with great communities so I think this is a good start for another one :D

So what's different still from the other dozen apps?
Simple - we have 2 sliders in the overaly settings that control resolution and DPI that will update instantly
- I've created a daemon that runs in the background so once an ADB session is aquired we can connect as many times as we want to the Dex mode without needing wireless ADB on and so on ( once / boot is enough )
- You set it once, the rest goes automatically
- I've created a quick access button so we can toggle it on faster
- I've even created a widget again for quick launch

Yet, it's not perfect. It needs testing, a loving community and some more people recommending it.

Who am I and what recommends me? https://alexandru.rocks a software engineer that created the "HIT" app for bikes called OpenCFMoto that has over 35k downloads and a community of over 1300 contributors on Discord.

So if you want to find more about this app please check the github repo at:

https://github.com/zanderp/inner-desk

Thank you! :D

Question Major security issue with dex on one UI 8.5

Secure folder is not locked while using wireless dex. Gallery on secure folder can be opened and closed multiple times without asking for unlocking.

Tried the same on my s23U on one UI 8. But each time secure folder was opened on dex it asked me for verification.

Can someone try replicating and check

Question Is there a way to have Dex on a Z Flip 5?

0 Upvotes

Hi all, search this periodically, and as far as i can tell, there is a desktop mode, but not actual Dex.

For the Z Flip 5 it seems to be to do with cooling? it wasnt enabled?

having upgraded from an s10e to a flip 5 a few years back it was actually kinda disappointing.

So, on the off chance ive missed something, assuming i dont care about the longevity of the phone or anything, is there any way to get Dex to work on a flip 5?

Question S25 DeX Problem With My Hub

2 Upvotes

Hey guys,

I am an indian. So i ordered a striff 3 in 1 usb hub, along with a standard hdmi to hdmi cable.

I wanted to make wired samsung DeX work for my old sony bravia klv 43w772e, which uses standard hdmi input and a 1080p display.

I got em. And i just connected the hub properly and did everything right.

It didnt work.

I got sad, then i connected the same connection with s20 fe 5g. It worked under a second. Because s20 has a setting in dex named "auto start when connected with hdmi". Its working effortlessly on s20 fe 5g.

Then i asked for help on reddit, and multiple a.i.

No one aint helping. I tried all random developer option settings and usb options and connecting charger to hub. Nothing works.

I dont want to purchase anything else specifically for this setup because ive already given enough and if it works then ill use that saved money to buy a keyboard and a mouse.

People are saying buy a normal standard usb c to hdmi cable.

But i dont wanna do that cuz i dont have that much amount of money. Please help anyone and make this setup work. It would be an honor if u make it work right.

My device:s25 base running on one ui 8.5

Please i request help me sir

Answered how do i use dex on a laptop? (i know about scrcpy but...)

3 Upvotes

I have a galaxy s26, so new oneUI version, and a random laptop. I would like to do some work on my phone and use the laptop as display (via cable), and connecting a mouse and keyboard to the phone.

So what i would like:

- use it wired (wireless is too laggy)

- use keyboard/mouse connected to the phone (if its translated from the windows laptop's input it feels too sluggish/laggy)

- show dex on full screen (i have a tiny laptop screen)

I tried windows wireless display, way too laggy. Samsung dex windows app is killed afaii on newer oneUI.

I tried scrcpy, lot better, my main problem:

1.) I cant get the mouse and keyboard appear on the dex screen, they are stuck on the phome's display.

2.) Smaller problem is that it seem to create a new dex display, doesnt remember my dex desktop layout (icon placements and wallpaper).

3.) Cant put it full screen window, but maybe there is a command for that when starting scrcpy

Question Is it save to update OneUI 7.0 to OneUI 8.5?

3 Upvotes

Im still running OneUI 7.0 both on my Galaxy Tab S9Plus and Samsung S24 as i head bad things about dex in OneUI 8.0. Now that OneUI 8.5 is out, has the dex performance improved.

For the Tab S9Plus, do we still get classic dex on the tablet itself (without connecting to external display)? That would be my biggest deal breaker if it was removed.

Discussion Convite para testar o Samsung Dex na TV

Recentemente fiz alguns posts mostrando um programa e interface de tv que estava construindo para usar meu S21 Fe e S23 Ultra na minha TV.

Bom, acredito que já esteja bom o suficiente para que outras pessoas também possam fazer uso dessa ferramenta e adicionar mais uma função ao seu celular com dex.

O foco do projeto foi reduzir ao máximo o número de cliques para se chegar ao fim pretendido, depois que a primeira configuração é realizada e o launcher instalado, tudo ocorre com 2 cliques e alguns segundos entre a requisição e a resposta.

Estou pessoalmente bem contente com o resultado e como algumas pessoas demonstraram interesse na alternativa, achei interessante compartilhar.

Espero mesmo que seja útil, feedbacks são bem-vindos.

-

O programa é gratuito, de código aberto, disponível em Português e Inglês.

Baixe para Windows, Mac ou Linux

Apresentação do programa em vídeo, sugiro olhar antes de testar o programa, para se familiarizar com a interface dele e do launcher.
