Is this real? WASABI MANGO UHD490?!

[randy hutajulu]

Is that real?? Really.?! It's even cheaper than 4K TV at that size and.. Damn.. 10 bit color IPS?? Seriously?

Is anyone here have any experience with this brand? I'm interested. Like.. Seriously!!!

Thanks.

Uumm.. Can u describe "limited appeal" sir? Maybe that will be helpful

[Regis_DeVallis]

Tech question for you guys. 

 

In the description from the link posted by OP, it says that the Vertical frequency is 60Hz, but the Horizontal frequency is 30 - 85Hz. What does this mean?

Uuummm..

Think I should start a new thread for it?

they should make a freesync  27" IPS 1440p 144hz for around 300-400! 
 

I like mangos!

[SolarNova]

Nice, 4k at a decent size for once.

 

Alas, still LCD. And those grey blacks. .yuck.

 

Even still, glad to see 4k becoming available across all screen sizes now ...almost.

 

Roll on OLED !!

If it says that, it's a typo, horizontal frequencies are in KHz.

Vertical frequency is what most people would just call "refresh rate".

Horizontal frequency is a technical specification that doesn't affect you as a consumer, and can be calculated from the vertical frequency. It's just listed there to sound impressive.

[NumLock21]

Yes, they're real. And I think Paul, from Paul's Hardware had a older model, the 30". He also did a 4K for $4K build which included the newer 4K one.

Another review

From the reading I've done, these large 4k Korean monitors are pretty decent.  Surprisingly, their QC seems to be on par or better than the likes of Asus.  Great value for sure, but don't expect a premium product at those prices.

i really want them to make an ultrawide version with 38-40 inch diagonally. that will be so much cooler! and maybe curved can do some magic

is there any IPS with OLED base around sir? i think that will be interesting

ouw... so we just have to take a look at vertical frequency? ok.. noted. thx sir

aahh.. interesting. i'll watch that sir

yea.. the prices are so interesting. i really hope that these monitors are available in my country anytime soon so i can see it in person. i can't buy a display without trying it with my own eyes first.

buying a monitor is always the same as u're buying another peripherals like keyboard and mouse. u need to experience it first

IPS is a type of LCD technology. OLED is a totally different branch of technology than LCD.

ouw.. what about color accuracy with OLED display? is it better than IPS? i have a samsung S6 which is OLED and i find out that i like the color on my other phone which is using TFT and IPS display. it's more accurate and have a wider gamut for me. 

correct me if i'm wrong sir

Color accuracy is dependent on the specific display and how accurately it's calibrated, not the base technology.

 

[spoiler=What’s the difference between AMOLED and OLED?]

Nothing. AMOLED is a redundant and unnecessary term in the computer technology industry, don’t use it. Just call it OLED.

Technically speaking, “OLED” is a more general term; OLED is actually quite a broad technology, it isn’t just used for display panels. It’s being explored for use in applications even as simple as regular interior lighting.

However, AMOLED is the only type of OLED which is suitable for use in computer-grade displays. So when someone uses the term “OLED” in the context of phones, TVs, monitors, etc. (which is 99% of cases) it’s already implied that you’re talking about AMOLED since there’s no other type it could be.

Saying “AMOLED” every time in a conversation about phones is like insisting on saying “computer mouse” over and over even when the conversation is clearly about computers and it’s completely unnecessary to specify what kind of mouse you’re talking about. Technically speaking it's not incorrect, but it is a bit ridiculous sounding.

So please don’t say “AMOLED” unless you’re in a very, very broad conversation about OLED technology that goes way outside the computer technology industry. Inside, it’s totally redundant and just sounds plain silly. It's the only kind of OLED that’s used here.

 

(Note: When I say “computer display” here, I am using it as a broad term which refers to the displays used in smartphones, tablets, laptops, TVs, monitors, etc.)

The AM stands for “Active-Matrix”. This is actually a type of addressing scheme, not really a type of OLED itself, I only used that wording above for simplicity.

An addressing scheme is the plan for a display panel's internal wiring and how the electronic control signals will actually be delivered to every pixel on the display. Since most displays have at least several million pixels, wiring each one to the display controller individually (a scheme called "direct-driven") isn't really feasible. All complex LCD and OLED panels in computer displays use the Active-Matrix TFT addressing scheme.

LCDs and OLED displays refresh one row at a time, moving from top to bottom. As soon as the display moves on to the next line, voltage is no longer being delivered to the previous line. Without voltage constantly applied, LCD subpixels will drift back to the "off" position and OLEDs will fade to black. “Active-Matrix” means that each subpixel has a capacitor which is charged when that subpixel is refreshed, and maintains the state of that subpixel while the display controller moves on to the other rows. Without these capacitors, each row would fade as soon as the display controller moved on, resulting in a mostly-black screen and a moving scanline, very similar to a CRT.

With a passive-matrix display (no capacitors), you need to deliver higher voltage to the pixels than with an active-matrix display to achieve the same level of brightness. Since the pixels fade away immediately they need to shine extra bright for a short time, while the pixels on an active-matrix display can be dimmer and just stay active for a longer period of time to output the same total amount of light. The largest disadvantage of OLEDs is their limited lifespan, and higher voltages make them degrade even more quickly, so for OLED displays in particular no sane engineer would ever design an OLED display as anything other than Active-Matrix unless it was intended to be disposable or otherwise have a very short or very light-usage service life.

So, “AMOLED” is a completely redundant term. All OLED displays in computer technology are Active-Matrix; that’s a given.

 

 

 

 

As it happens, there's actually no such thing as an "LED" display, you've been had by the TV marketing machine! "LED" TVs are nothing more than LCDs in disguise, using LEDs for a light source instead of fluorescent tubes like older LCDs. But the display panel itself, where the image comes from, is still the same old LCD technology we know and love.

 

OLED displays are entirely different, using individual lights for every subpixel. LCDs use a single light source behind the display panel, which gives them a number of inherent drawbacks such as poor contrast, washed out dark scenes, backlight bleed, poor uniformity, and usually a narrow color gamut, in addition to the weaknesses of LCD panels themselves, which include slow pixel response time, low refresh frequencies, and limited viewing angles.

 

OLED displays have:

• Instantaneous pixel response time (not to be confused with latency; that's determined entirely by the display's processor and software)
• Infinite contrast ratio and the ability to display perfect black
• Extremely high refresh frequencies (as high as the display controller/software can handle)
• Extremely wide color gamut
• Perfect viewing angles

Unfortunately OLED displays do have one drawback, which is a limited lifespan. OLEDs degrade in brightness over time. Regular LEDs degrade too, but since LED-backlit displays have a single strip of LEDs which illuminates the entire display at all times, the LEDs are all active at the exact same time at the exact same voltage/brightness level. So they all degrade together, which means all that happens is that the monitor slowly gets dimmer over the years, so gradually that you'd be hard-pressed to ever notice.

 

Meanwhile, since OLEDs have individual lights for every pixel, they don't degrade together. Each OLED only degrades while that particular pixel is active. This causes the color balance to shift over time, and the screens develop "burn-in" issues, leaving a permanent after-image on the screen.

 

Of course, researchers are working hard to address this issue, as it's currently the only major problem with OLED displays other than manufacturing cost, which will gradually lower anyway as OLED becomes more common.

 

 

 

No. If a certain OLED display has poor color accuracy then that is entirely the fault of the display vendor, as it is up to them to calibrate the display properly. OLEDs have excellent color accuracy when properly implemented.

 

Oversaturation is something that occurs on any wide-gamut display, including wide-gamut LCDs. It's not an issue with OLED technology itself. Most wide-gamut displays have profiles for standard-gamut output in case the user isn't working with wide-gamut-optimized software. If the display vendor has failed to provide any profiles or calibration options to compensate for their display's wide color gamut, that is entirely their fault for improper implementation of a wide-gamut display panel. An OLED display will not be oversaturated when properly calibrated.

Color accuracy is dependent on the specific display and how accurately it's calibrated, not the base technology.

Thx for the info sir. Do have any OLED monitor sugestion that i can try? I hope it's available in my country so i can see it first and compare it with some trusted IPS monitor.

FYI, i'm using dell U2410 right now. It's an old monitor but still it's a very good monitor for the price at that time and yea.. I think it will be a good idea to upgrade it before it's getting too old

There are no OLED monitors being made right now.

Ouw.. I thought samsung made one already. Ahahaha...

They're one of the first company who introduce this technology right? I wonder why they don't make one
