They also state (in the ebay ad) that they are NOT compatible with Apple Mac computer....why?
 
Looks like a TV panel made as a monitor, you can find UHD 42" TV from Changhong or LG.

I purchased a Crossover 44K from dream_seller and I am having issues with him on a return due to a defective display port input (you cannot insert the cable due to a damaged port). His first response was that he could not see the pictures. Then he stated that the monitor was not laptop compatible - completely avoiding the damaged display port issue. Ironically, he lists the monitor as compatible with a macbook. Anyhow, both my desktop and laptop work fine with Display port 1. One of the reasons I purchased the Crossover was that it had dual display ports that would allow me to keep my desktop and laptop connected without having to swap cables. I have purchased in the passed from Dream Seller without issue (27" Qnix) but then again never had to deal with a return/defect. I would be very leery of spending 1200 on a monitor with this kind of support..... Next step is to open a case with Ebay/Paypal/Credit Card company.

Couple of years ago I had a 30" Crossover arrive badly damaged from Big Cloth Craft who were meant to have good customer service amongst Korean sellers. I opened a eBay case and BCC would sometimes take a week to respond to e-mails but funnily enough tended to reply in about a day if I sent replies through the official eBay messaging system.

About a couple of days before the eBay case would have got escalated they paid for return shipping and asked me not to escalate or things would not work out well for me. So that put me in a difficult position, if I had closed the case I would have had zero leverage on them if further problems had occurred. Luckily for me an eBay rep contacted(think they do this routinely) me and asked how the case was going, after explaining things they automatically escalated my case for review by eBay staff.

End result, eBay ruled in my favour and gave me a full refund. BCC were not happy and asked me why I had escalated - but I've heard eBay tend to favour buyers if the seller tries to appeal.

So I'd suggest opening a case for a defective product, send messages via the official eBay message system and hopefully somewhere down the line you get a refund - either through escalation or agreement with the seller.
 
No - Ebay has some of the best buyer protection policies. I am not worried about getting my money back. The issue is with service once your dispute period runs out on both Ebay and Amazon - 1200 is a lot to risk.... Regarding my case, I have opened up a return request that I can escalate after 4/30. Given dream_seller's "not compatible with laptops" response, it looks like I might have too.

I ordered this monitor. I really don't like VA panels and hugely prefer IPS and I did alot of research beforehand. You can find lots of user review links below (all in korean so you'll have to translate).

The reviews confirmed 4:4:4 chroma at 4k/60hz. Not really any other info on higher resolutions and hz. Will update when I get it.

I ordered from Amazon because if you look on their A to Z guarantee page: http://www.amazon.com/gp/help/customer/display.html?nodeId=541260 the seller has to provide a return address IN the US or free returns to the international address.

why pick a korean 42" when there are 40" Tvs and monitors capable of 4:4:4 4k@60Hz at sale for less?

If this wasabi mango could do 1080p@120Hz as well...

That should be enough not to buy this.

Only buy items that are of highest quality you can afford.

Yup.

Read the XB270HU thread. That unit has a US affiliation, it's returnable, has a full US warranty, yet is plagued with so many QC issues. Would you gamble $1.2k on something with effectively no warranty, unknown quality control, that you have to go to Ebay/Amazon arbitration to request a refund? You do pay more for the privilege of returns, ensuring a defect free unit, and a full warranty. I personally could not live with a single dead pixel or one dust under the screen.

For those wanting an IPS 4k monitor, why not go for the LG TV? It's 4:4:4 and IPS.

Pretty sure they just copy pasted that from one of the various Korean 1440p monitor's page. I mean, this monitor doesn't even have a DVI port, so I don't really know why it would make any mention of it.

LG TVs typically use PWM, random Korean off-brands are typically smart enough to use direct current. It also has the added benefit (to some) of having a DP 1.2 port.

On quality control, perhaps. But the people interested already know that before buying, so what's your point?

The monitor very obviously has a scalar because it's multi-input, and there's pictures of it being used with a PS3, so the compatibility copy-pasta is clearly incorrect. Dream-seller posted the same thing on the X-STAR's QX/DP2710's (single input; no scalar) page.

Every monitor known to man has a scalar. The issue is if it's any good? 85% of scalars on monitors are garbage and non-native res look like crap.

If a seller can't even get the specs right on their advertising page, how confident are you that what you think you are buying is what you're going to get?

Having a scalar means it would accept laptop/console connections and adapters, whether or not it displays non-native resolutions well is not what I was referring to. The point is: the information posted is erroneous. I'm correcting that, as WorldExclusive's original post was based on the notion that it does not accept certain signals.

Korean sellers have been caught lying in the past, but generally only about overclockability. There's not really much they can lie about here, considering it's been confirmed to run 4:4:4 by Korean owners. I mean, what else is there? Regardless, there's always a risk factor to buying from a Korean vendor, and we'll never know anything unless some brave soul buys one. That brave soul appears to be aldoxzx, and I'm quite interested in hearing how his purchase goes.

Speaking of which, this isn't actually advertised as flicker-free. So aldoxzx, if you'd be so kind, please check for PWM using this test (instructions are at the top).
 
Let's hope that somone gets a review up soon, in English.
This monitor might be FANTASTIC and a near perfect 40" 4K monitor with an IPS screen (which would make me, as a photographer, very happy)


...or it may not ;-)

Now down to ~$800 shipped on eBay

Someone got it at overclockers and says it has ~15/20ms latency.
Click to expand...

He compared it to his other monitor, which he believes has 1ms of latency. Since that is the response time only, he got it wrong. He said it was 15-20ms behind his PB287Q . The PB287Q which he compared it against is 16ms behind the Dell 3007WFP.
http://techreport.com/review/26510/4k-for-649-asus-pb287q-monitor-reviewed/5

Let's say the Dell 3007WFP response time is 14ms. This review didn't have the lag, but let's be generous and put it down as around 5ms. The input lag on the Dell is probably around 19ms.
http://www.tftcentral.co.uk/guides/content/dell_3007wfp.htm

The PB287Q is 16ms behind the Dell. The Wasabi Mango is at 15-20 ms behind the PB287Q, so let's say a frame at 16ms. 19 + 16+ 16 = about 50ms of lag.

Let me know if my conclusion is off based on the data provided.

Ignore his testing.

Timer based methods of measuring input lag are always horribly inaccurate, prone to extreme user error (very common), and are completely useless when compared against a non-CRT.

You can read about input lag testing methods here.

Disregard his testing; read above.
 
Hey guys what is the quality of this panel? I dont understand why it is so cheap being a AH-IPS panel.

How does this monitor compare in picture quality and colour to the likes of the philips BDM4065UC
 
Careful! I noticed that Newegg was selling 2 versions of this monitor. The "Perfect Pixel" and a cheaper version that can up to 10 bad Pixels. The cheapest price now on EBay at this time is $750.00 and is the SE Version that can have bad pixels.
 
Im tempted to get one too, but still very sceptical because of the low price. I really believe what you pay is what you get.

It's your choice to have ignorant beliefs. The UHD 420 is not that much cheaper than the name brand 40" 4k displays, and Wasabi Mango only advertises and operates in Korea while the big brands advertise and operate world wide. Guess who has higher operating costs and needs to make up for operating costs with higher prices?

Anyway, I see you have been asking silly questions in unrelated threads in [H] and OCN (asking about the Wasabi Mango vs. Philips in Crossover 44k thread) as well about comparisons of un-tested products (Wasabi Mango UHD 420) vs reviewed ones. Until proper reviews come out, no one can provide definitive answers, and it is highly unlikely that someone will buy both. AHVA/IPS/PLS panels with accurate colour presets have more vibrant and even colours while VA panels have darker blacks, less glow, slightly slower pixel response times in most cases, and far more motion blur+flicker if they use low frequency PWM (4k 40" Philips and 4k Samsung TVs).

Please explain to me how it is silly to ask questions about a product before purchasing it? Isnt that what normal ppl do.

A google search of wasabi mango uhd420 resulted in links to those crossover threads because people were posting about wasabi mango in those threads, the reason why I asked in there.

So basically, at minimum at best this UHD420 still has very high input lag?

Ok so according to you it is silly, to ask about a product that people are already discussing in a different monitor thread, found by a google search.

So we must be all silly including google, because I didnt search for 'crossover'.
 
The numbers may not be accurate, but it's definitely slower than the PB287Q which is a slow monitor in the first place. You can still make conclusions based on the limited information.

Low price? It isn't a huge difference from name brand 4K sets. LG themselves sell 4K IPS for not much more, the 31MU97 can be had for $1170 on Amazon right now. Or the 49UB8500 - $1190.

Even though it's slower than the PB287q, it is still ok for gaming as long as it is under 25ms input lag which this monitor should have by the sounds of it.

PB287Q measured at 10.6ms
http://www.displaylag.com/asus-pb287q-review/

As "inaccurate" timer test shows this monitor 20 ms behind that makes it's input lag roughly 30.6ms
Click to expand...

Should also add that the leo bodnar test is inaccurate by up to 9ms; the PB287Q most likely has virtually zero input-lag based on that review.

=DEAD= actually measured around 22.5 ms with SMTT2.

However, I've noticed =dead= also measured 27.9 ms for the 27" PB279Q, whereas prad (oscilloscope) and pcmonitors (SMTT2) both had measurements well under 1 frame of input-lag. Someone is clearly wrong here; prad has been known to have inaccurate measurements in the past, but generally all the reviewers using SMTT2 have been pretty close to the same, and =DEAD= is a pretty experienced reviewer. I suppose there's a possibly that he received units with different firmware.

Thank you SO much. You are pretty much the only source out there that i've found that has user reviewed this panel. I'm curious if you could chime in on light bleed? Over here, a user is explaining that the IPS light bleed on a monitor this big, sitting so close may not be a great experience: http://www.overclock.net/t/1549360/crossover-44k-uhd-led-40-inch-monitor/790

Any input would be appreciated. -THANKS!
