Still very decent frame-rate and perfectly playable. Good to know a 680 can do it. I'm actually quite interested how would 680 handle surround with 3x 2560x1440 I would guess that still above 30 fps but its just pure speculation.

Unfortunately nVidia dont support 5 screens so I'm atm walled into AMD garden for now. Got my screens before these awesome value Koreans came around so still at 1920x1080 per screen but hey I'm saving up and when funds allow then I would like to get couple of these 27'' as well. Lets say three .. just for the sake of comparison wink.gif Would have to get separate card for these three tho. And as 680 is pretty good .. well see well see .. I'll need the displays first.

Warning: I would recommend not buying from red-cap. Their listings state they test their monitors and have a warranty, but they sent me a display that was damaged before shipment. This is their response:

"1. about the bezel, sorry for that , the manufacturer , Crossover, is a Small and medium enterprise , so the exterior condition of some monitors might be not good comparing to Big company (apple , samsung ) we'd like to apologize for that behalf of the manuafacturer. but it is slight problem and we hope you understand for that."

Here is the damaged light:
It seems way too excessive. This is mine, not a crossover but it's the same panel really.


Return it imo.

You can try to return it. I don't think any sellers specify the amount of yellowing that constitutes a replacement.

I had that problem and I Bigclothcraft was excellent and rectified the issue. Mine was a bit worse than yours and BCC offered a replacement (he pays for return) or a $100USD refund. As if wasn't a big problem unless it's on an almost white page I just sold it to my friend and BCC offered me $110USD off a new one. This time he said he will check for any imperfections at all. Took him about a week longer to check and was sent out last night. Should arrive tomorrow.

See if you can get it replaced, most sellers are nice.

The power led changes from red to blue when connected to a video source, and the brightness buttons cause the led to flicker for a couple seconds before stopping.
I pulled the back side off, and found an issue on the LED Driver board. A mosfet on the board that was burned and some of the insulation on the board is curled back. I believe I found a replacement, and once it gets here, I will replace the mosfet.
This issue is most likely caused by the cheap/faulty power adapter, and could be the source of the yellowing forming on some screens after being on for a long time.
I have pictures of the board and issue, but they are on my phone and I'll have to upload them later.
Also, for the guy with the green screen issue, that sounds like the video processor has overheated, and separated from the motherboard. If there is someone in your area that does laptop video chip reflows, they should be able to repair the board, but it will most likely cost several hours labor.

If this were true, brand new panels wouldn't be coming with a fair amount of yellow tint right out of the box. It would imply that they have been in use for a while before getting packaged and shipped, but many are sent straight from factory warehouses or only opened to test proper operation / number of bad pixels. Perhaps it can contribute to the worsening of the tint over time, but something else contributes to the initial amount of tint.

I was reading through the thread, and someone had said they smelled it, and there was a yellow spot forming in one side of the screen. This is the yellowing I was referring to, not the overall yellow tint out of the box.

Thanks for the input. It has been several days of emailing back and forth with red-cap but it sounds like they are going to let me return it, still waiting for them to send me details on how, I keep asking.
post #2079 of 6483
After reading several weeks (for sure more than a month), I've ordered the Crossover 27Q LED-P from Accessorieswhole (ebay).
Luckily I've got only one pixel defect. Its defect is weird. Usually, it's a dead pixel. But it's a bright red stuck pixel if the background is white. It is in the mid, but on the top of the screen. So it's still acceptable.

I've ordered from Accessorieswhole because he guarants that there are only 3 defective pixels. No matter which type of defective pixel. He's also the only one who's selling A+ Crossover monitors. Have a look at his auctions with pixel perfect options. He have photos from A+ labeled parcels of ALL Crossover models.

Most of all other sellers just refund you 10$ per pixel defect. But probably you would get a full refund if you tell them claim via PayPal. With Accessorieswhole you surely would get a 100% Pixel Perfect monitor. Otherwise he would refund you it immediately.

I DIDN'T ordered my Crossover with Pixel Perfect due the fact that the chance of a flawless monitor is still high and because 3 defective pixels should be still acceptable. And 100$ more for Pixel Perfect was just a little bit too much for me. 50$, okay. But no 100$.

I hope this helps some people here smile.gif

by the way: These lazy fed-ex couriers are lazy. If you google it, you'll notice that it's known that they just throw the memo in your mailbox to inform you that they "unfortunately" missed you. In my case, it was just lazyness by the courier. I was not at home, but two other family members were at home for sure. So, if you're planning to order (with urgency) from oversea and if it's possible, you may better choose any other courier instead of Fed-Ex.
