Well, I was in market for the Crossover and visited their site. They now have a overclock model 2730MD and -P for the guys here who want to run at 125Hz. Personally, I was in market for the 27Q LED-P but surfing for so long got me to think about the 30Q5 Pro (75Hz 5ms) or the 2730MD (125Hz 6ms) I'm in more favor of the 30" since they give 102% color gamut vs 72% since I'll be mostly using this for Photoshop editing pictures of my kids. What do you guys think about these new monitors? The 30" runs about $500 plus shipping if you know some people in Korea that might ship it to you. I'll be asking my friends over there to ship it after making sure there is no defect, stuck, dead pixel. Perfect Pixel on ebay on 27Q LED-P runs at $499 shipping included so I guess I can spend nother $100 or $150 more to ship it from Korea on the 30"

http://crosslcd.co.kr/main.html?tmp=product&pg=2730MD-P it's new and they advertise it to be over clocking model capable of 125Hz Most likely they won't be selling this unit for awhile since I'm sure they are running low on stock just to keep the PC cafes in korea. Every street in Korea pretty much has a PC Cafe and they are mostly for gamers and they usually have 50 to 100 PCs there.

Oops, I see the link already given. Anyhow looks pretty cool!!

Awww man i JUST pulled the trigger on a white Crossover 27Q not even two days ago, after months and months and tens of hours of research into upgrading my 8 year old dying 21" Samsung CRT, to buy my first ever LCD! Now that it's literally on the plane on its way here i see this

I've put up with a random green tinge on this monitor for about a year, i would've happily waited a little longer and spent an extra $100-$150 for 120hz.

Well, 2730MD isn't even listed on gmarket. Still under production maybe. When it hits the US I think it'll be around $550 to $600. I'm just few days away from pulling the trigger on a 30Q5 Pro since I won't be gaming. I wonder what color calibration tool I need to buy to make those colors true. By the way, there is a seller on ebay that sells the 27Q LED-P that is supposed to have a A+ panel. The seller claims to have the only model that is perfect pixel from the manufacturer not the second hand or seller rating. I looked it up and seems to be true. So, if I can't find a Perfect Pixel model on the 30Q5 Pro, I might just get the 27Q for now.

Just wanted to post that I've went ahead and ordered the 2730md-p. I've actually already gotten the tracking info minutes ago. From the looks of it, I might be one of the first in the States lay my hands on one of these as according to eBay only 1 has been sold and I must assume that's me.

This will be my first Korean IPS and I'm hoping the claims of 125hz aren't just smoke. I won't be terribly disappointed if it is as I'm really in it for the gorgeous picture I hear so much about. I currently game on a 23" 120hz LG TN display and like it but for some reason I've got an itch to check out these larger Korean IPS monitors.

Registered here to get the ball rolling, will let everyone know what I think when I get it and have time to tinker with the refresh a bit. With that said, does anyone know of a good tutorial to follow for display overclocking? A brief search brought up a Youtube video I think will suffice though any tips would be appreciated.

Specs:
GTX 680 stock
i5-2500k stock
128ssd Windows 7 x64

http://www.ebay.com/itm/New-27-Inch-Crossover-2730MD-LED-Pivot-HDMI-1-4a-2560x1440-WQHD-S-IPS-Monitor-/130781649105?pt=Computer_Monitors&hash=item1e733198d1

I'm pretty sure the P at the end of the model number only designates that it has a different, higher quality stand which pivots.

As for if it scales at 1440p, well I guess I'll find out. Heard some discussion that some people think that there is a scaler at all will be enough to eliminate the possibility of an overclock that high. We shall see. I aim to find out

Very interested to hear your thoughts when you get it.

I will be certain to come back here and let people know my findings on this monitor. The monitor has already shipped. Based on others accounts of shipping from this seller, unless I have any issues with customs, I should have it by the 15-17 of October. Might take me a day or two after receiving to determine OC'ability. It's my first display OC, hoping it goes smoothly. Of course it may not OC at all so there is that.

Cheers

OMG It's HERE!!! lol. Woke up this afternoon and it's sitting on my couch, thank god roommates were around to sign for it. Seriously though, it shipped Friday from South Korea and it's sitting in my living room on Monday afternoon. That has got to be expensive for them!

Time to dig in

This monitor uses the same multi-input board as the Witech Multi Limited Edition, and a monitor pulled before release from Achieva Shimian, and one released by First Semiconductor (I have a prototype of it). The reason for that is the 125hz operation is bogus. The dvi controller board allows an input of up to 125hz. So your computer will say "Heya. I'm sending 125hz (or 130hz, in my case) to your monitor! All is well!". The monitor is saying "Oh sweet! A 125hz input! I can totally take that! Thank you!." Then it tries to pass it to the Timing controller attached to the LCD panel and the monitor is like "Hey...TCON...buddy, I got 125 of these frames for you. What??? What do you mean you can only accept 60 from me? Fine...I'll send you frame 1, 3, 5, 8, 10, 12, 15, etc...."

Basically...it frame skips. It will accept an input higher than 60hz. The OSD will tell you that it's outputting 125hz. But it only ever sends a 60hz signal to the LCD panel itself. Sorry to burst your bubble.

Edit: My comments are in regards to the 27" model. I don't have any info on the 30" monitor. It's very well possible that it hits 75hz.

Ok, so I admit I am new to the display overclocking thing but it's not looking great.

I am able to go overclock all the way up to 120hz and get an image though it doesn't look like it's any smoother than the default 60hz. I also get artifacting at 90hz and above. I am currently using the dvi-d cable from my older 120hz monitor and haven't tried the supplied cable yet or hdmi 1.4a.

Also have a stuck green pixel on the left hand of the screen which is wish I could say is hard to notice but it sticks out pretty bad on dark scenes. Light bleeding on off-center bottom left as well. Not ideal as of yet. Will do some further testing.

** It appears HyperMatrix is correct. His explanation would describe what I've noticed. Oh well.

Oh crap, I guess I better cancel my order before they ship. Thanks for the heads up and do you think you might be able to return your order?

Ah well - to good to be true. I love my CrossOver LED-P - was really hoping they'd make a 120hz+ version .

I've sent an eBay message asking for a refund.

The lack of 120hz did not affect my choice to return. The stuck green pixel, excessive light bleed, poor black levels, ghosting, and poor scaling/image quality over hdmi did. In fact if the monitor did OC to 120hz I still don't think I'd stick with it.. I already have a 120hz TN that in all honesty has much better IQ imo. Was expecting more from IPS. Oh well. Maybe I got a dud? Hard to say without anything comparable to check it against.

Really wish I could have looked at this first but as it stands I don't see myself using it over the display it was meant to replace. It's pretty much a downgrade in every sense except size.

He should accept the return, but it's highly probable he'll make me pay return shipping which will sting. Still better than being out the whole $450 with a monitor I won't use.

As with everything, your results may vary.

Cheers

Try this to fix that stuck pixel http://www.flexcode.org/lcd2.html - you can also try "massaging" the area. I'm sure you can google and there are a few home brew methods you can try.

As for the Backlight bleed - make sure youre not confusing it with "IPS Glow" - that looks like this http://www.youtube.com/watch?v=-eA2IjlotJU

to tell the difference, move your head side to side, youll see the IPS glow move as you move. Or take a pic of your screen about 3ft+ away (preferably 5-10 ft) - make sure youre level, in a completely dark room using the "Black" option in that LCD Repair tool link i pasted above.

To fix IPS glow - view the display a bit further back, im about 1.5 feet away, in darker games like Left 4 Dead 2 - i set the brightness lower and move the monitor further back still.

Thanks jerrolds, +REP

Pretty sure it's light bleed. I did look from multiple angles and the bright spot did not move.

The pixel issue was something I was aware of that I could possibly resolve. I did some slight massaging and the color flash video's for about 10 minutes or so to no avail. I could put some more time in it if that were my only issue though with everything else I'm just not satisfied with the overall quality of the monitor. The stand though is fantastic. Really like that part of it.

It's already back in the box waiting for instruction from seller. Think I learned a lesson about the whole "grass is greener" saying.

Cheers
