I've tried searching the thread but I don't have time right now to read through 91 pages of posts... are the Catleaps consistently reaching 80hz or higher at 2560x1440, from the sound of it? What about the Achieva/Shimian? Should they both technically reach it other than the EDID since they're the same panel? Is there any disadvantage to the Catleap other than the higher stock stand (which I don't care about)? I saw a summary claiming the Catleaps have a high defect rate or somesuch but the poll doesn't reflect that....


I always knew that IPS had better color accuracy and that whole bit. Just had to see for myself. :)

 

I have my monitor at 100Hz. But nothing really feels different from 60Hz. Any tests I can do to differentiate the two refresh rates?

Yep, adds better "depth" to the picture and more vibrancy in my opinion as well when I've done side-by-sides. Glad you're happy with it! smile.gif

Thanks for the extra result... as far as hz testing, you can try the setup ToastyX did to make sure it's working, otherwise really it's just supposed to be less juddery if being driven at >= the refresh rate of the panel.

Don't know if i made a mistake since i have a 27" samsung led 120hz monitor but i already have a buyer for the capleap if i don't like it

I'm in the same boat as you, will be interesting to see if the Catleap can compare to the Samsung in games. The higher hz definitely has me intrigued. I'd be pretty happy with anything over 80hz on an S-IPS at that resolution.

Just placed my order for the Catleap Q270 from dream-seller. Hopefully no defect and a big upgrade from my LG 32" 1080p TV monitor.

I also noticed a fair amount of back light bleeding at the lower right hand side of the screen.

Try playing a game with vsync on and see where your cap fps is. If it is running max 100fps or over 60fps then you are running higher hz

Do you notice any uneven whites displayed on bottom third of screen?

The defect rate claimed by that guy was
1: Back when only 6 samples were in, 4 good: 2 flawed
2: Calculated wrong as 4good/2bad is a 33% defect rate, not 50% as stated.

It is looking MUCH more promising now that more results are in (current rate is 20%) with no more reports of bad monitors for a few pages. It also seems that 3-4 posters thus far have been able to consistently reach 80-85+ Hz on the Catleaps.

Pretty even whites. I have uneven blacks.

120hz monitors and CRTs are perfect for measuring ghosting/input lag and other things on unknown monitors like this. At whatever refresh rate you set the Catleap to, could you run this test?

http://www.lagom.nl/lcd-test/response_time.php

Then post the results for comparison? If you have an SLR handy, that would be even better, as we could definitively measure ghosting and input lag on the "overclocked" Catleap.

I would do it, but I don't even have a fast TN panel to compare it to.
