iiyama G-MASTER G4380UHSU-B1 Red Eagle

Pros

  • 144Hz refresh rate on DisplayPort, however ‘only’ 60Hz on HDMI
  • Large screen, with 43 inches it is not a dull monitor
  • Not too much fuss
  • The sound is fine, but nothing to write home about. A soundbar/headphones would ‘make up’ a lot
  • Vesa mount
  • 4K resolution & FreeSync
  • Remote control

Cons

  • A matte finish would have been nice
  • VA panel, which is not really ‘very’ bad, but the colors come out differently than with an IPS panel
iiyama G-MASTER G4380UHSU-B1 Red Eagle Review

Introduction

iiyama has put a good monitor on the market with the G4380UHSU-B1 Red Eagle. The 4K 144Hz (on DisplayPort) looks smooth and beautiful. Especially when gaming, this gives a completely different experience. During work, there is a huge (partly due to the 4K) overview. A great combo as far as I’m concerned.

Well, the G4380UHSU is a 43-inch monitor, so you can also expect a fairly large box. Those package deliverers are always happy with me! 😀

With 43 inches, the iiyama G4380UHSU is not a weak monitor. The thing that is immediately noticeable is that the monitor reflects reasonably well. But, hopefully, that shouldn’t spoil the fun while gaming.

What I find a very nice addition is the headphone hook on the back of the monitor.

By the way, the USB ports are located on the left side of the monitor.

The back and stand of the iiyama G4380UHSU have some fine options. This monitor has a VESA connection (200 x 100) so that it can be hung. This allows the stand to be detached. By the way, the stand also has an option for cable management with the clip, which is of course also ideal.

Furthermore, the monitor does not look very overwhelming at the back. Whereas you would expect this with a ‘gaming’ monitor. There are those monitors that have exaggerated lines, colors, etc. This one is just black, done…

The G4380UHSU has two HDMI and two DisplayPort connections, of course, there is also a headphone jack. The other side has a power connection.

For the use of computer games, I grab my PC. The super compact (and beautiful) NZXT H1 v2, contains the Gigabyte Z690i Aorus Ultra and Gigabyte RTX 3070Ti.

When the monitor is started, the entire room is briefly illuminated with the logo of the G-Master.

And just as an illustration, which some are still mistaken about. 4K is a very special resolution. By default, Windows 11 sets this to 300%, so that you see something. If this is simply set to 100%, you have to sit pretty close to your monitor.
And that results in a lot of space and overview. Great to have your Outlook/Word/Excel open (at 100%). Have never been able, to get as much work done as with this monitor.

And then when running some benchmarks on the PC you pretty much strike back. In this case, with Tomb Raider on the 3070Ti. In this case, there is still room for improvement concerning the graphics card. Still, it looks spectacular at 4K. And that also applies to Far Cry, Battlefield, etc. The monitor can handle it, that’s not the problem… now the card!

IIYAMA G-MASTER G4380UHSU-B1 RED EAGLE

Of course, I am also curious about what a console does on the 60Hz port.
Yes, Super Meat Boy… know your classics…

Don’t worry, this game has been played in the meantime. Now I’m working on Forbidden West. And what wonderful games these are too. The graphic is ultimate. And then being able to play games on such a monitor is a given. I have friends who play in full HD, and that’s fine. But there is so much detail and extra ‘image’ with such a monitor like this at 4K.

IIYAMA G-MASTER G4380UHSU-B1 RED EAGLE

To elaborate a whole sub-chapter here: gaming at 60Hz is fine with quiet games. With shooters that is just a bit less, at least … I’m used to 144Hz on an IPS panel. Then everything feels like a step back. If you’ve always been on 60Hz, then this is fine.

Software/Menu

What is a shame is that there is no software for this monitor. Competitors are unfortunately more advanced in this regard. This allows you to link a program to a preset to give your monitor a certain setting. But, on the other hand; for normal use, you have to ask yourself how often you are going to switch between different presets.
Even though it can be a very important use case for some, I have never used it myself on my monitors. Especially because I switch a lot between Word, Chrome, etc. If you have a different preset for Word than Chrome, then you are constantly switching between different colors / presets.

Fortunately, the menu is easy to operate with the buttons on the right.
The source/input can be changed via the top button.

The first menu is the Picture Adjust where the contrast, overdrive, black tuner, etc. can be adjusted. The menu is quite extensive. There are plenty of options to set up the monitor to your liking.

The menu also allows you to set which input should be selected, whether standard HDMI 1/2, DisplayPort 1/2, or Automatic.

IIYAMA G-MASTER G4380UHSU-B1 RED EAGLE

Standard presets can be set via various user modes. For example, if you are going to play games on the PS5 via HDMI (or via a DisplayPort to HDMI switch), you can set a preset with the overdrive, etc. This means you only switch between the presets and you don’t have to set everything from scratch every time.

G-sync/FreeSync

The G-Master G4380UHSU only has FreeSync. The advantage of this is that it can also be used on an Nvidia graphics card. At least, my 3070Ti just picked this one up. By the way, the FreeSync only works with the DisplayPort at the 3840 x 2160 resolution and picks it up between @48-120Hz.

And that was quite noticeable. During hefty dips in Battlefield 5, this was quite straightened out. Also in Forza Horizon 5, during wooded areas, it was well taken care of by both the graphics card and the screen.

In the months that I’ve been allowed to test this monitor, I’ve never seen a flaw while gaming. The monitor is extremely fast during shooters and racing games. You will eventually get your desired result. The only weak point could be the graphics card. But it can also be worked on with an upgrade to a better one. After all, the new generation is also waiting around the corner…

In addition, don’t forget that this monitor can also be used as a TV. Hang an Apple TV or something similar on it and you can just endlessly Netflix … at 4K. And that looks good.

Conclusion

With the G-MASTER G4380UHSU-B1 Red Eagle, iiyama has in my opinion brought a great 43-inch monitor to the market. Several readers have already asked me if I would like to review such an iiyama monitor (keep sending requests as well), and I am only too happy to do so. In the months that I have been allowed to use this monitor, I have been able to test it in various ways. From gaming to extensive security monitoring and Word/Outlook/Excel work. With so much screen space at such a resolution is very nice. Where I normally use a 38-inch monitor with a 34-inch monitor above it, this 43-inch is more than enough. And that’s saying something. I also often sit back in my chair for gaming – especially with racing games – and with such a monitor you have a lot of overview.
If you are gaming from the couch and the screen is a bit away, then this is also a great monitor.

The real only downside to this monitor is that it is glossy. During dark cutscenes in God of War, for example – or when you’re hopping around in a dark area – you see yourself…

The monitor’s speakers are… fine, but not great. I do recommend adding headphones or a soundbar/hi-fi set. Then you also get much more out of your gaming/movie experience.
Let’s face it, this monitor also just has a remote control. And that is super convenient. Especially in the case of being able to switch, adjust, etc.

If the HDMI could also function at 144Hz or even 120Hz, this would have been a real winner. Fortunately, there are possibilities to use an HDMI – DisplayPort switch from a console to at least use the 144Hz. Conveniently, it’s not. That extra option would make it the ultimate monitor for the console gaming market. For the PC market, this is just a very good monitor, the 144Hz looks great. That it is a VA panel, you take that with the 43-inch in this case – also given the price – for granted. It’s just great for gaming and working. What more could you want?
By the way, with 4 inputs there is certainly a lot to connect. Ideal for when you’re in a very boring meeting, just crank up that console quietly…

The iiyama G-MASTER G4380UHSU-B1 currently costs €599 (time of writing) and I must admit that I don’t think that is much for such a monitor. No, it’s not an OLED monitor or even IPS, but just a fast VA. An ideal thing for gaming and (home) work too.

The iiyama G4380UHSU-B1 gets 5 out of 5 stars from me.
