I am definitly new here - a thread on RFD pointed me in this direction so I have been sifting through this, as well as the Catleap owner thread for the past few days.

I have also been looking around at sellers on ebay, and considering buying one of these panels over a much more expensive U27. So far, based on some very rough observations, it looks like 5-10% of people here who have received their monitors have had issues that would require the unit to be shipped back to Korea.

I checked how much this would cost from Canada - a minimum of $150.

So my question is: is there any way to buy one of these panels online with a warranty that would require the manufacturer (or some third party) to pay return shipping if the purchased unit becomes defective within the 1 year manufacturer's warranty coverage time frame? I don't think that the additional ebay square warranty ($50) even covers return shipping.

For me, $300-$400 for a monitor is too much if there is a significant probability (over 5% for me) that I would have to pay at least half the cost of the unit itself to ship it back and gamble again.

I will admit that I have not read every post in the 383 pages of this thread. I have searched though and have not come up with a clear answer.

My question is two fold. First, will these monitors work with an nVidia GTX480 video card? The GTX480 is not specifically mentioned in any of the grids that are posted with the monitor information on some sellers eBay listings. It does seem that the grid is copied from one seller to another so any deficiencies in the original grid just get re-advertised over and over.

The specs on the GTX480 are:

Display Support:
YesMulti Monitor
2560x1600Maximum Digital Resolution
2048x1536Maximum VGA Resolution
YesHDCP
YesHDMI
Two Dual Link DVI, Mini HDMIStandard Display Connectors
InternalAudio Input for HDMI
[http://www.geforce.com/hardware/desktop-gpus/geforce-gtx-480/specifications]

I see that this card is dual link DVI and supports a maximum DIGITAL resolution of 2560x1600. It seems to me that this card falls within the requirements of the monitors discussed in this thread.

And now for the second portion of the question. If the GTX 480 is supported does it only work once the operating system (Windows or OS X [hackintosh]) is booted and not at the BIOS portion of the boot. Is it correct that BIOS boots at a VESA resolution of 640x480? In particular my motherboard is a Gigabyte GA-EX58-UD5.

I look forward to any information that you may be able to provide to help clear up my confusion regarding this topic.

Sincerely,
Hackintosh 2

Hello,

I just received my Shiman QH270-IPSB today from GreenSum. Unpacked it, set it up with my 11" MacBook Air and Mini DisplayPort to Dual-Link DVI Adapter and the high-quality Monoprice Dual-DVI cable and...

...nothing. :-(

The MacBook Air will not recognize the display no matter what I try:

1. I tried the included cable instead of the MonoPrice one -- nope.

2. Reset PRAM on the MBA, rebooted, etc. When I reboot the MBA with the monitor plugged in, the computer behaves as if there is a second monitor attached. I'm assuming login information is on Shimian but the display is just black, so I can't log in, and on my MBA display I just get the linen background. When I unplug the display adapter, the login screen returns to the MBA screen.

3. Shimian displays a solid red light when off (I'm assuming?), and when it's on there is no light. When I shut it off the light goes blue for a second, the screen flickers, and then the light goes to a solid red. No idea what this sequence means.

4. All cables are secured and tightened.


Unfortunately, I don't have another machine with a DualDVI output to test with nor another laptop to try the adapter with. I did try the displayport -> dualdvi adapter with another 22" monitor and it seems to work okay.


Any thoughts?!?!?

I'm not sure ,but I don't think any integrated graphics card will support any higher resolution then 1200p.

It's supposed to work.

@bom and @Eagle1337 I appreciate both of your replies.

In the end, I disabled my Firmware password on the MBA, reset the PRAM (cmd-opt-P-R at boot), burned some sage, did a little circle dance and boom the monitor came up. Unplugged and replugged the displayport adapter and it came back up again, so that's a good sign. Running at the full 2560x1440 with the Monoprice mini-displayport -> Dual DVI adapter and the included dvi cable.


Some notes:

* Thing thing is amazing. I have a 27" iMac at home and this is certainly on par. I haven't peeked too closely for dead / stuck pixels but I think there may be one or two. No big deal.

* Stand isn't great but the design of the housing is pretty clean. I like the tempered glass / flush look.

* I'm using a Spyder4Express icc profile someone posted up and that evened out the colours quite nicely.

* Shipping to Edmonton, Alberta, Canada took 6 days, including a long weekend (Victoria Day long weekend here in Canada)

* Didn't pay any duties. Package was marked with a value of $190 USD.

* Double-wrapped bubble wrap on the outside. Box was in great shape.

* That's my dog. He's awesome.


If anyone has any OSX-specific things they'd like to see, let me know.

Thanks!

Here's the one I'm using. I can't remember where I got it from.
