Wasabi Mango UHD 400 Review | Level One Techs

I can't find the frame rate option mentioned in the video?

One thing that was not mentioned in the video is the Picture in a picture. I have found it very useful when working an anther system and don't want to set it up on anther monitor somewhere else.

Being able to have a 20 inch 1080p PIP that you are doing an install on with a webpage right next to it on the same monitor is amazing.

Dudes, will you please use the correct term Ultra-HD when talking about a UHD monitor at 3840×2160 monitor, and use 4K only for monitors capable of 4096 width.
I know that "4K" is used as a marketing term for selling TV's but you are not TV salesmen. The cinema standard is 4096×2160 and not quite 16:9.

In a previous job, I programmed video editing software for professionals (TV stations, production houses etc) and in that world you used the correct term or GTFO.
There are real 4K screens out there - that are real in more than name. They are usually very costly and also capable of a bigger colour space than TVs and most computer monitors.
Funny enough, Apple has such a screen in an iMac.

I did the review on the pretty inexpensive microboard 4k with 4096x2160 and pointed out explicitly it was that res because it's pretty unusual in the pc display space.

I'll try to be more pedantic in the future

Same here. Got the UHD 400, upgraded the firmware to Real4K0405VS and no frame-rate option!

can you link me to the fw you used? I can try it here lol. Was that necessary for freesync? I've always had to fiddle with freesync to get it working reasonably -- was delighted this one worked out of the box.

This is really tempting.
Just had my 30" Dell 3008wfp Ultrasharp fail on me. I can probably fix it, but real tempted to just go bigger.

Ay. Freesync worked out of the box!

The firmware site is http://www.wasabimango.co.kr/bbs/board.php?bo_table=down
UHD400 is number 28.
And the directly to UHD400 http://www.wasabimango.co.kr/bbs/board.php?bo_table=down&wr_id=37

And finally, My UHD400 seems VERY sensitive. I get these periods where the display just flickers on all ports HDMI, DP, and even on just the OSD. This occurs when I wipe the monitor, attach new cables, or just get handsy with it... Very strange. I finally mounted the monitor on the wall just to get if off my desk and off my reach. When this occurs, I can usually get rid of the flickering by just unplugging and plugging back the power cord (multiple times).
Similar to the video here: https://www.youtube.com/watch?v=MBd2qIUao3s

The seller offered to ship a new board but I haven't followed through. I have opened it to see the guts; but didn't feel like putting in the work to analyze it more.

On another note, I really want to see HDR working on this monitor. That would be a very nice icing on this monitor.

Bought one. Lucky with no dead pixels. But It cost an arm and a leg with the taxes in EU.
But since I'm working with 3d rendering a lot, feel that colorwise this isn't as good as I need, even with calibration (using Colormunki Display and some hints from the forum). Especially comparing to my old Dell U2713HM.
Now deciding if I should rather find a buyer for it and get an ips 34inch 3440x1440 ultrawide instead :|

I did an initial impression/mini review for this awhile back. https://forum.level1techs.com/t/wasabi-mango-uhd400-40-4k-va/97442/139

Some things to note that is not in the video:
The panel is most likely a 100% sRGB TV panel
Calibration is shit out of the box
Metal frame gets hot when running
Popping noise when turning on from off status, unless something is plugged in the audio jack
Panel is semi-glossy
It's flicker free if you have it at 100% brightness
Response time is around ~30ms

I have also started to get issues relating to distortions even on the monitor's system level i.e. their menu is affected. I think the AD board is a bit dodgy (unreliable), only have been using it for 3 months with roughly ~5-8 hours a day of screen on time.



I brought it from accessorieswhole 3 months ago and I have contacted them for a replacement AD board. I trust they will give me a replacement AD board seeing how my previous interaction with them have been good.

Hi everyone! I've been using this monitor for half a year. I'm happy with it and I would probably buy it again, but there is one annoying thing. It's nowhere close to PWM free. Even at 100% of brightness, some images blink. One example is the default vertical scrollbar in xterm: sample screenshot found on the internet

Do the scrollbars blink on other otherwise okay monitors if you watch this image at 100%? I'm just curious if this happens only on mine.

Interesting. I will test later. Try disabling sharpening or image processing in the menus?
I get weird flickering on scroll with moire patterns as shown in the video but otherwise its fine when the image is static.

Thanks for the quick reply! The effect is way less visible with "Color bypass" set to "on." (This mode is not acceptable for other reasons though.)

By the way, an xterm screenshot on wikipedia displays this effect as well.

I'm trying to decide between the Wasabi Mango UHD 400 and the Samsung UN40KU6300. Any suggestions ?

Haven't used the samsung but got burned when I bought the U28D590D. The UN40KU6300 -- thats a TV no displayport input though? The DP input is pretty nice. The ultrawide 3440x1440 is nice if that's your thing and you want a high refresh rate.

I was told by my supplier that their manufacturing contact is finally taking my requests for a 27" 2560x1440 144hz monitor seriously and they cooked one up due out early next year. So we'll see about that one.

I decided on the UHD 400. I'm planning on mounting it to my monitor arm but I'm not sure if it would be too heavy? I have the Ergotron LX Dual Side-by-Side Arm. Do you think it would work? Also I know I'll need some kind of adapter. What are those really nice monitor arms you use?

Spaceco and thats probably too heavy for the dual side by side arm unless you get an adapter that has the one monitor supported by both arms?
we had to get special spaceco arms for our uhd400s

Hey fellas, do you think the Mango UHD400 is a good screen to delit? I don't like the glossy glass in general. I prefer the normal 'matte' display look. So I was thinking about getting a UHD400 after all, because Wendel likes in his review and its RGB and it's a big display.

As for the glossy part, it is semi-glossy, so you have to be careful, where you put lights behind you.

Other than that, I've had it for eight months or so, and I like it. It's far from perfect (read through this entire thread and another one here about this monitor) but I can live with the shortcomings.

You cannot remove the gloss on this one it is plastic not glass and fused with the polarization filter. The gloss isn't awful it's in-between MacBook whatever and Dells business class lcd matte
