I think this is a new TV/Monitor and it's really a dirt cheap ($400 USD) 4k60Hz 4:4:4 PVA screen.
Most obvious problem is no DisplayPort but it does have 4x HDMI 2.0 so that is manageable with the Club 3D adapter). Second most obvious problem is that these sellers aren't the usual players but they don't seem too bad, either. Are there any other obvious problems with this screen?
At $400, it's taken some of my attention away from buying a UHD430. This is mega-cheap!
So anyway, anybody have any experience with this or know anything useful to help me know whether to buy this or not? I'm not willing to be a guinea pig (sorry).
UPDATE: Previous versions of the eBay listings mentioned IPS as a feature. This mention of IPS in the eBay listings are being corrected. I figured that was incorrect.
A bummer with the UHD430 is that there is only one DP. I've got two other systems that I'd like to hook up to the monitor and they only have DP connectors. I've got a pair of DP-to-HDMI cables but they don't support 4K@60.
Sooo... I am speculating that I think we're about to see the next generation of Wasabi Mango products. Not only do we have this new U400 model but the UHD430 models seemed to disappear off of eBay last night (although the UHD490 models are all still there). I find it hard to believe that it was a coincidence that all of those different sellers (4+?) simultaneously pulled their listings for the UHD430 last night unless there's a reason for it.
I don't know anything about the actual manufacturers. Any way to find out more information? I think a lot of people would like to know if they should hold off a few days/weeks on a purchase if a new generation of product is about to hit. Sadly, I think we're probably a year too soon to see DisplayPort 1.4 but one can wish, right? ;-)
I've been following the story about the Korean screens since TS started talking about them. I myself am looking to replace my 24'' Iiyama ProLite B2403WS, which in 2008 was the cream of what you could buy as an LCD screen here in Europe and cost the ridiculous sum of 850$. But I'm still using it and plan to continue using it for LANs. I'm telling you this to press the fact that I'm the kind of person who'll buy very expensive but durable stuff and keep it until it's dead and unrepairable. The drawback with these screens is that you're playing the lottery each time. @wendell Seems to never have had any trouble with his screens in regards to dead pixels. Some, on the other hand, have had really bad experiences. And having to send the stuff back will immediately ruin the deal. Not to mention that the seller changed his terms a couple times in terms of dead pixels counts. To sum it up, you have no guarantees. I'd recommend you find the videos TS has made on the monitors and check the thread pertaining to the videos. You'll identify people who are well informed and other who've given feedback, sometimes pretty bad, sometimes good. I'll throw my hat in the ring at some point, but my strategy will be to pay the guy extra so that he checks the screen himself for any defects. I'm ready to pay more up front rather than waste my time later.
I would say that I have a different stint on things, too. I am willing to pay less for the risk of rolling the dice and having a few dead pixels. Out of the 50+ korean monitors (different models, 27s, 40s, etc) I've had maybe 3 or 4 I've had to return in warranty (one and maybe two of those was not right away, one was damaged in shipping).
So if I want something absolutely guaranteed perfect, I might buy something else. For the volume I deal with I would say it is a "commercial" level so maybe that colors my choice a bit. However the substantial savings makes it worth it.
I would say maybe 10% have dead or stuck pixels but honestly that type of thing doesn't bother me unless it is very severe or there are a lot of them. Does it bother me if I were paying full retail? You bet. Half off a comparable monitor? I'm willing to tolerate more.
I recognize that sometimes you roll the dice and lose, too, which is nothing to be upset about. For me the net overall savings is it is still worth it. but if you just buy one monitor I can see how you might be upset if you lose the lottery.
It's a lot like buying an overclockable cpu from intel. you might lose the lottery, or you might win. Just know what you're buying going into it. :)
You can have good luck or bad luck, its basicly just a lottery. Those panels are of course cheap for a reason. You could allmost buy 3 panels for the price of one A brand panel, and thats of course the thing, especialy if you need a volume of them. But if you loose the lottery with a single panel, i still think that you could send it back under warenty right?
I think it also realy depends on the usage goal you have for a monitor. If you are an graphical designer and you realy need a decent panel, then those Korean panels are most likely not a thing for you. But it would be better to buy something A brandend like an LG AH-ips or so.
Yeah, I definitely understand the lottery nature of the game. Even with all big box and some (not all) online stores, we're moving towards that lottery game even there with how often they're beginning to resell returned DOA items as new. I don't like it, of course, but I understand it. And if I understand it, then it's a set of parameters I can work within. You know, kinda like politics at work: I don't like them but I can deal with it. As others have said, the massive cost savings make the game with playing. And there's a chance I could be in the market for a larger bulk purchase for my developers if I like the first screen well enough.
