Just so every one knows, the Flat Panels Timer is very inaccurate. The SMT Tool is the only reliable program for measuring input lag apart from using an oscilloscope which only PRAD.de does.

Flat Panels HD timer falls under the Stopwatch w/ Vsync category in terms of inaccuracy vs an oscilloscope or the SMT Tool.

An example of the Stop Watch/FPDH Timers inaccuracy can be found in most of TFT Central's reviews. Take the Dell U2212hm for example, they "measured" 24ms. PRAD.de used an oscilloscope and measured 1ms of input lag on the U2212hm. TFT Central "measured" 10.6ms for the U2412hm while PRAD measured 0.9ms. TFT Central measured 15ms for the Asus ML239H while PRAD measure 1.5ms.

PRAD did test the scaler free HP ZR2740W and it had 4.9ms of input lag. These Korean models should be similar.

Unless the SMT Tool or an oscilloscope are used any input lag value you come across will be wrong.

Has anyone succesfully VESA-mounted a Catleap? Looking at the pictures, it looks like even after removing tho back grey-cover, there is still a leg that you need to remove. Just wondering how difficult that process is. Thanks!

Check out the catleap club through the link in the first post. There's a visual breakdown of it there.

Did anyone receive a crossover yet? Or are people still waiting for it to arrive? Seems there is a lot of hype for this product.

You are right but the reason i put those results there is to compare my two displays. Using the same method on both should keep the error equal or at least close between them. Based on visual observation i can tell you the lag is noticeable and I think if it would have been between 0 and 5 ms difference i wouldn't notice.

I wanna stress that i never compared to any crt or any other reference display that has 0 lag.
Also i aknowledge that there many variables which i didn't take in consideration or some which i can't control but with the tools i have is the best i can do.

It's good that you pointed out that the results might be incorrect. Every day we learn new things and it's good to have accurate information.

So I just ordered the CROSSOVER 27Q LED-P 27" DVI Computer Monitor (QHD) 2560X1440 16:9 Pivot...
Hopefully I'll get a fully functioning unit...

same here comrade , let's hope for the best! I am pretty optimistic, the odds have been pretty good for non-tempered glass models across Achieva and Catleap brands. I will post pics and stuff as soon as possible but I did request a dead pixel check so it will probably be sometime next week before mine arrives. I ordered from dream-seller in case anyone is curious.

I pulled the trigger and purchased a 3View PCBank PB2700 last night from Dream-seller! It's the cheapest with the best reviewed and has the potential to sit the lowest given its double jointed stand. My desk is kind of high so the height was a bit of a factor. If the stand doesn't live up to my expectations, I could probably get a replacement mount/stand for the ~$80 difference between the 3View PCBank and the Crossover LED-P so I thought why not.

Dream-seller has already marked it as shipped so hopefully stock isn't an issue on this monitor since it has lower demand or was that Green-sum who marked items as shipped before he actually shipped? Still waiting on tracking information though - so excited! My first ever ebay purchase too lol!

Pulled the trigger on the catleap for $369.50 from Green-sum on ebay. I had to email to get the tracking number, but it should be here today woot. So excited, hopefully no dead pixels or especially no DOA. Although, for the price I could live with 1 or 2 dead pixels if they are off to the side. Still hoping for none of course.
