According to the manufacture's website, the UHD550 does not indicate either way if it supports Freesync. However, if you look at the name of the latest firmware update it indicates otherwise " UHD550,420_ firmware .zip (2.2M)". As soon I receive the monitor I will confirm if it supports Freesync.

Latest Firmware Update:
7/31/2015 - UHD550,UHD420 Freesync update UHD550420_FreeSync.zip 2297k .zip file
10/4/15 - 0910V1
MERGE.ZIP 461k .ZIP file

Firmware Update Steps:

Manufacture steps:

1. unpack the compressed file
2. Loosen the extrusion of the file "MERGE.bin" file, copy the file to a USB memory.
3. Connect the monitor's power on kkeunhu memory USB port
4. Power On
5. When power is applied, the green LED will flash red. Wait until the flashing stops. The time is approximately 3-4 minutes.
(Note that removing the USB flashing speed before stopping wanjyeon Hebrews blinking is slow or jammed, remove the outlet simyeon this be so)
5. When the update is, after removing the USB memory Unplug the power from the wall outlet and will fit again.

1. Download the firmware
2. Format a flash drive to FAT32
3. Extract the firmware to a folder you have created. The extracted file will be a bin file
4. Copy that file into the flash drive
5. Power up the monitor normally
6. Plug the flash drive into the USB port that is next to the HDMI ports and Dataport(not the blue USB ports on the left side of the panel.)
7. The monitor indicator light on the bottom left will start to flash red then green. This will last a minute or two. When it stops and stays green the update is complete.
8. Remove the flash drive while the monitor is still on.
9. Unplug the monitor from the wall or whatever power strip you are using.
10. Plug the monitor back in, it will be reset to factory settings. The default connection will be dataport. If you see the "mstar" logo come up then you know you have done it correctly, just hit the source button if you are connecting via HDMI.

Passive 3D:
The monitor supports Passive 3D, but it has to be activated by using software tools.

Movies:
  • Bino (Select output: Even / Odd)
  • Potplayer (Automatically detects 3D video using filename tags)
  • Stereoscopic Player - MVC 3D video (Blu-Ray 3D) - (Viewing method: Row Interlaced, Left Line Top)

3D only works in 100% dpi scaling. There is an option to ignore the settings of dpi scaling in potplayer if you're using customized dpi scaling.

UHD550 Pixel Perfect Review

First Impression

It’s MASSIVE! Honestly, when I unboxed the monitor, I thought I was crazy for purchasing a 55” monitor for my computer! After I connected it and testing a few games I was amazed. I thought I was amazed with my 434K, but the immersion of the 55” is on another level.

I really like having the real estate for using multiple browser windows, word documents, and comparing excel spreadsheets when working on my finances.

The aluminum border/bezel is really sleek looking compared to the black plastic on the Crossover 434K.

This monitor is huge and if you don’t have the desk space it can be overwhelming. I would also say it may take a few days to get used to it, but once you do, you will never go back to anything below 40”!

Packaging

I received the monitor on Friday (9/25) and unboxed on Saturday evening. The monitor was shipped in a wooden crate (which I requested as many UHD420 owners have reported cracked screens). The wooden crate was specifically made to fit with a tiny bit of room to remove the box. The box itself was in great shape; no dents, dings, or damage.

Contents

The monitor came with an Owners Manual (in Korean), USB 3.0 Cabel, HDMI Cable, DP Cable, Remote (in Korean), and power cord with NA adapter.
Warning: Spoiler! (Click to show)


Condition

There are ZERO dead pixels.

The aluminum bezel and screen border was covered with some plastic peel. Nothing to it to remove, just start at one edge and peel. I believe some UHD420 owners have reported peeling of a plastic coating on the screen when removing the plastic around the aluminum bezel. I did not experience this issue whatsoever.

Office Setup

The opinions of this monitor are based on my current office setup, desk, lighting, and seat alignment from eyes to monitor. What I visually see may vary from others (as well as each LG Panel is not the same).

Desk:

U-Shape – depth of desk where monitor sits is 18” which does not leave much room for keyboard and mouse.
Warning: Spoiler! (Click to show)

Lighting

The back of the monitor faces a window (almost half of the monitor is in front of the window). I normally leave the blinds semi-open and have no issues with glare (see picture). At night, I have a green LED strip that lights up the back of the monitor. I also turn on a lamp in the corner of my room which has 3 LED Natural Light bulbs. Again, I have zero glare issues.

This is how much I leave my blinds open during a typical day. Warning: Spoiler! (Click to show)

Green LED light (This pictures makes it seem like the backlight bleed is worse. This is NOT how it typically looks) Warning: Spoiler! (Click to show)

Viewing

The floor to the seat of my chair is 18”. This is max height my chair. To be honest, this is too short compared to the height of my desk and the monitor. The monitor is 29 1/2" tall and my eyes only come to 20" on the monitor. I may have to purchase a new chair that will raise higher or purchase one of the TV Stand mounts that I can tilt the monitor some.

I am 22” from the monitor (measured from eye to monitor screen). I feel this is too close. My desk is only 18” deep so it does not leave much room. I did a test and the ideal position for me would be 40” from the screen (eyes to monitor)

Calibration

I am not an expert in monitor calibration, so I am describing what I am visually seeing. Out of the box, the default settings are pretty good. I am sure it could be improved, but I need to read up on the different software calibration to see which one is best suited for this monitor. The black seems deep (based on the black color test I performed – see ‘Color’ below) and the whites did not look washed out. The colors in general seems much more vibrant than my Dell 27” IPS. I am sure the default settings are not the same for each monitor; thus how mine visually looks may differ from yours.

I have not toyed around with any of the additional settings (hue, saturation, gamma, etc.) in the menu so I cannot comment on it at this time. I will report back when I do.

Here are my default color settings within the menu: Warning: Spoiler! (Click to show)

FreeSync

My monitor came with the updated firmware which includes FreeSync within the menu options. At this time, I have no way of testing it out as I own a GeForce Titan X. I plan on picking up an AMD card over the weekend to test FreeSync. I will edit my post after the test.

The monitor nowadays comes with the updated firmware which includes FreeSync. If for some reason the monitor does not have the FreeSync option in the menu then an update will need to be performed. According to Wasabi Mango homepage the FreeSync firmware update was removed. However, I received a copy of the firmware from @Nom and posted in the firmware section with the #1 post.

Test Results

The environment in which the tests were performed was no different than any other day in my office. The only difference that should be noted is I performed them at night (with the back corner lamp on) instead of the day with natural light.

All tests were performed with native 4K resolution on Windows 10 Pro. The cable used in the test with Accell DP 1.2 from Amazon. My eyes were 22” from the monitor except when I stepped back to take full monitor pictures.

All pictures were taken with my iPhone 6s Plus.

Note: Please let me know if there is a specific test you would like me to perform and how to go about running the test.

Input Lag

I performed two input lag tests. The first test was with the Crossover 434K and the second one with the Dell 27”. This was my first time running an input lag test; I hoped I did it correctly!

Below are the results:

434K – Seems to have the same input lag as the UHD550 Warning: Spoiler! (Click to show)

Dell 27” – Seems to have the same input lag as the UHD550 Warning: Spoiler! (Click to show)

Frame Skipping Check

Unfortunately, any refresh rate above 60Hz skips no matter if it is 4K native resolution or 2K resolutions. I was hoping the UHD550 would have been able to perform at 70-75Hz on 2K resolutions frown.gif

Below are the results:

Native 4K resolution at 60Hz – No skips Warning: Spoiler! (Click to show)

Native 4K resolution at 65Hz – Skips Warning: Spoiler! (Click to show)

1440P resolution at 65Hz – Skips Warning: Spoiler! (Click to show)

1440P resolution at 70Hz – Skips Warning: Spoiler! (Click to show)

1080P resolution at 65Hz – Skips Warning: Spoiler! (Click to show)

Black Test:

I performed a black test from dry creek photo and I am able to tell the difference between RGB (0,0,0 and 1,1,1). I tried to capture it on my phone, but it would not show up.

4:4:4 Chroma

I don’t have an HDMI 2.0 cable to test 4:4:4 Chroma. I am ordering one from Amazon and will edit my post after the test.

BGR/RGB

I am not sure how to accurately test this. I visited Lagom’s test page, but did not see a specific test to run. If anyone knows how to properly test BGR/RGB, please let me know so I can perform it.

Ghosting

I am not sure how to accurately test this as my iPhone camera does not have shutter speed settings.

Overclocking:

Since frames skip at anything above 60Hz, overclocking is a no go. See frame skipping check above.

Observations

Screen

The screen is not matte, but not super glossy like my old 27” Catleaps. As with any typical gloss screen, if you touch it your finger print or smudge mark appear. Any dust free or microfiber cloth will wipe them away. Reflection is very minimal; only lighted objects can be seen (i.e., window or light in the background – see picture). Depending what is on your screen at the time, you can barely make out the features of your own refection.

The bezel around the screen is aluminum with a sleek look. There is hardly a bezel around the top and both sides of the screen (more specially it’s on the side as a casing to hold the screen in). The bottom of the screen does a visible bezel and it’s just shy of 3/4 of an inches wide (see picture). Even though there is no aluminum bezel on the top and sides of the screen, the screen is not edge to edge viewing like the (Dell XPS 13” laptop). There is a black bar that runs along the top and sides of the screen and is 3/8 of an inch wide (see picture). One thing to note is open applications on the task bar are reflective on the aluminum bezel (see picture).

Looking at the top of the screen from the side, there is no visible curve defect as some of the Crossover’s have (see pictures).

Backlight Bleed

Minimal backlight bleed comparted to my Dell IPS 27” and Crossover 434K.

Hiding edges

Depending on how you look at the sides, top, and corners of the screen, the image may appear to be behind the screen. According to @AndrewWOT, “The “hiding edges” is a parallax effect.” It affects the WM UHD420, UHD490, and Crossover IPS panels. I particularly notice it more since I am sitting close to the screen. Once I am able to sit further back from the screen I don’t think the parallax effect will be an issue. See pictures below for the parallax effect.

Top Warning: Spoiler! (Click to show)

Passive 3D

I am unable to test passive 3D at this time. I don’t own a pair of Passive 3D glasses. According to @Sheppaul, “You can use any kinds of (LG 3D TV) Passive Glasses.” The model number he is using is FPG-200F and can be purchased one eBay.

Remote

Interestingly when the 434K was connect for testing purposes and comparison the UHD550 Remote controlled both monitors at once. Check out video.
Warning: Spoiler! (Click to show)

Overall

Fantastic monitor and absolute great buy! I recommend the UHD550 to anyone who wants a 55" 4K immersive gaming experience with vibrant colors and decent deep blacks without breaking the bank! Personally from owning three Crossover monitors and now my first Wasabi Mango – WM has a much sleeker looking bezel than the cheap plastic. As I stated in my first impressions, this monitor is MASSIVE! After a couple days of use the total size of the monitor grows on you…in a good way!

To any future WM UHD550 owners if you have any questions or concerns, post on the forums and we will help you the best we can.

I really don't mind forking a bit more for this one, as long as it doesn't have any issues, like at all.

Did you order the pixel perfect version?

I'm in the same boat as you! I have the same thoughts and this is why I want to try it. I could not find any reviews on it so I thought I would be the guinea pig! wink.gif

Yes, I ordered the pixel perfect.

Can't wait to see your take on it. I've got the 490 and I'm more than happy with it. Freesync is enabled, but I have no real way to test it to make sure it's actually working.
