Note: Again, forgive the pictures. I do not have a real camera. They should still contain the information wanted.

This is the back of the stand with the monitor and plastic cap removed. As you can see, the base on the left side is warped - probably due to shipping this monitor with the stand on. I gripped the left side as close to the front (closest to the monitor) as I could and pulled it away from the center of the base. I also has to pull the right side into the base probably 1° in, and I now have level portrait mode...

That I'll never use.

Moving on! I decided while the monitor was apart I'd take pictures of all the PCBs and any other miscellany.

This is found mounted on the right side of the back. You can see it through the vents on the back of your monitor.

Here is the last PCB I could find. This one and the previous hook up via the flat cable that you see in the previous PCB and the slot in the middle of this one. I couldn't get a picture of the backside of this PCB, I wasn't feeling dexterous at the time.

Well, that's it! I haven't looked at the Yamakasi PCBs to know the difference. Any information on that'd be great.

My new battle station is here.

FAQs

1. What is this I keep hearing about the power brick?
Users are reporting that the supplied power adapter isn't compatible with US outlets (110v). The text reads, "AC 230V ~ 50/60Hz 1.2A". I have personally tested it with my multimeter and was able to get a constant 60Hz line frequency and ~24v DC. If you're still paranoid, you can buy a similar adapter on eBay or a step down/up transformer. Some users have contacted dcsamsungmall whom acknolwedges the problem and will replace the adapter free of charge (maybe not).

Hi,
New update for adaptor.
I have got answer from manufacture technician team.
They don't recommend to use 220v adaptor at USA. It can cause some problem.
Appropriated adopter should be used.
We are planning purchase free volt adaptor but is little bit expensive.
So it effect price of crossover monitor in the future.
Thank you

FROM: dcsamsungmall
From today we will replace the adopter for 110v adaptor to US.CANADA
You can get 110v adaptor.
Then, this last one below seemed like a generic email sent out likely to his various customers thus far, as opposed to the two above which were private messages to me on ebay...

Hi,
Thank you for shopping from us.
We believe you are using our crossover monitor without problem.
But some customer who are live in USA $ CANADA has complaint regarding A/C Adapter.
We believe you are using this monitor with correct A/C adapter (110v) , but if you are still using A/C Adapter for Korea (220v).
It could be trouble in the future. So we recommend you to change to appropriated adaptor.
If you have inquiry please feel free contact me.
Dcsamsungmall
Best regards
Here is the original email again that I had sent him just yesterday:

TO: dcsamsungmall
It seems you are selling many of these monitors to USA & Canada. I know because I learned about it on an internet forum. Recently some people have been having problems with these monitors just stop working and we are wondering if this is because of the power brick that it ships with - Picture:http://img534.imageshack.us/img534/4660/dsc0785.png In USA & Canada the voltage is 110-120V, but the power brick shows 220V. Can you please inquire with the manufacturer if it is safe to connect this power adapter to 120V or if this could cause problems with the monitor or even cause a fire?If the manufacturer says we should not run it at 110-120V, can you please ask for exact specifications of power adapter, ideally if you have a URL of a model number we can buy only to replace it? Thanks in advance!

It's not that none of the adapters can handle US voltage....but the inconsistency with which that translates to 24v is the problem.

HE IS GOING TO SHIP ME A COMPATIBLE ADAPTER.....FREE OF CHARGE.

If you're going to buy a Crossover, or any other monitor, buy from dcSamsungMall. Excellent customer service.

2. Is this similar to the Yamasaki Catleap, Achieva Shimian, and PCBank 3View I keep hear about?
Yes, they all use the same LG S-IPS 8-bit LED panel. The difference is the circuity that drives the monitor. However, a review for PCBank 3View showed it have a slightly lower input lag than the rest.

3. Then does this monitor overclock?
Currently only early batches of Catleaps (2B) are known to overclock past 60Hz. The same cannot be said about CrossOver which are most likely locked at 60Hz.

4. Are there any US sellers or do I have to buy from someone in Korea?
Since this monitor is strictly produced overseas (mainly S. Korea), the only way in order to get a hold of some in the States is by doing a group order (100+). Right now bQvle is working on acquiring a price estimate for a 100Hz Yamakasi Catleap Q270.

5. What's the difference between the 27Q LED and LED-P?
LED-P can pivot (-P "Pivot") or rotate vertically as shown here. Other than that, they are essentially the same display.

6. Is there any IQ between tempered glass and the regular gloss display?
No difference whatsoever. Same picture quality but the tempered glass model has more of a Apple feel. You also risk getting dust stuck behind the glass barrier.

7. What's the difference between a A-, A or A+ display?
While these use the same LG S-IPS panels found in Dell, HP, or Apple monitors they are the "rejects" so to speak that didn't quite meet the company's quality standards. In our case, we might have some minor backlight bleed (normally found in the bottom right-hand corner) and some dead or stuck pixels.

If you have any questions about the CrossOver, or know which questions are likely to come up often, PM them to me so I can get them answered for the FAQ.

I plan on answering concerns about overclocking, the power brick, and build quality.
Anything else, please PM me!

Getting the folks who are working on the Catleap overclocking and PCB comparisons in here to see what we have from the other thread and how it compares to what they've found so far might be good for discussion to get this thread moving.

Also, wow... dcsamsumgmall's prices on CrossOvers just shot WAY up, $479.50 for the LED-P and $461.40 for the fixed stand.

Some things you might want to consider adding to the OP:

adeptus's informatoin on the power brick from the seller

akg102's info on the power brick aswell

MrSpoon's pictures of the internals

Your pictures!

Geglamash's setup

Geglamash's pictures

& let me reiterate what I said about the poll.. It's too tough, I think people are putting monitors they absolutely love in the "bad pixels" category because they have 1 stuck or dead pixel that they have to strain to even find and it doesn't bother them at all. Like me.

But they should still be put in the bad pixel category, even if it's just one. Or make another choice for "1 bad pixel". They still aren't "perfect" monitors.

I'm thinking about purchasing one of these monitors but I have a few questions, maybe some of you can help me out
smile.gif


1. The 27Q model here: http://www.ebay.com/itm/320865513557 is the stand just like in Jagz's picture (black with white trim) or is it completely white?

2. Can these ones still overclock the refresh rate?

I thought about getting the one with pivot but the fixed stand version looks nicer to me and I never really use tilt/pivot on my current monitor anyway.

Thanks.

1. That stand is black with a white trim.
2. I don't think we have enough people with CrossOvers to have a definitive answer, however it's highly unlikely these can go above 60-65Hz.

The LED-P stand is very sturdy, most similar to a dell. I needed height adjustment, but if you know you don't, say a couple bucks and get the more basic stand.
 
#18 ·
These monitors are great value nonetheless even if I can't overclock them but I thought I'd ask the question anyway. That's good to hear about the stand, I actually have a Dell monitor myself (U2311H) so I definitely know what you mean in terms of the quality level. I'm just finding that I never use it... so yea like you say, might as well save a few bucks in my case.

Thanks for the quick reply and answers.

Yep, I bought a replacement brick.
This is the one I bought, as its been verified to work by other members with similar monitors.

Ordered my Crossover LED-P from dream-seller, but he forced me to pay a 35$ shipping fee because EMS won't ship to Italy... still a damn good deal though, cheapest 27" 2560x1440 monitor starts at 600€ here.. hopefully it will arrive soon and unscathed

I would love this monitor and not be upset about a single stuck pixel.... However, the stuck pixel is bright green near the center of the damn monitor. I hope it gets unstuck so I can enjoy the monitor. Love the resolution and the IPS clarity. Any recommendations for color calibration?
 
#24 ·
If you have a stuck pixel try to gently massage the screen. I had a similar issue with my Ben Q (stuck red pixel) and it was fixed by massaging the area about an inch and a half around the stuck pixel. Just a thought.

From my experience there is no help for dead pixels. Hope this helps.
