Got my IPSB in today. Doesn't seem to like anything over 65hz, so either it's my video card (8800gtx) or the shimian's just aren't going to be accepting higher refresh rates like the catleaps are.

Can't wait for the backlight bleed pics.
How does the ghosting compare to other 27in monitors?
Surprised at the Catleap feedback because it "looks" so much more polished than the Shimian.
It leans about 1/4" when measuring edge to edge. I tried pushing it to the left but it doesn't help.

My comment about the backlight was actually a pro, not a con. It doesn't flicker more than a CCFL monitor.

The pixel response times seem typical of an IPS panel without overdrive.



85 Hz proof pics (catleap):

I set the camera's shutter speed to 1/10th of a second and took pictures at 60 Hz and 85 Hz.

I used Refresh Rate Multitool, which is a program that synchronizes with the monitor's refresh rate and draws a bar moving from left to right once per frame.

60 Hz:
catleap-bars-60hz.jpg

85 Hz:
catleap-bars-85hz.jpg

Notice how more bars are drawn in the same amount of time at 85 Hz, and no bars are skipped.



I also did the old mouse cursor test:

60 Hz:
catleap-mouse-60hz.jpg

85 Hz:
catleap-mouse-85hz.jpg

Notice how more cursors are drawn in the same amount of time with less spacing between each cursor. The movement is perfectly smooth with no skipped frames.

Note: If you do the cursor test, make sure to use a 1000 Hz or 500 Hz mouse, otherwise it may look like it's skipping due to mismatched rates.

For reference, this is how skipped frames look like:

This is the real deal. It can actually do higher refresh rates properly, and NVIDIA users might be able to get more than 85 Hz if the pixel clock is not limited to 330 MHz.

The 97 Hz limit seems to be due to the pixel clock hitting the DAC limit of 400 MHz. I bet it could hit 100 Hz if the timing parameters were bumped down a bit, but I don't have an NVIDIA card to test this with.

Wow, I wonder why the Achievas have such a hard time breaking 70hz while the Catleaps can go to 97. They use the same panel, don't they?

Also, it's important to note that Dream Seller doesn't wrap everything in bubble wrap. dcSamsungMall is still worth a try then.

My Catleap just came in. Triple bubble wrapped. thumb.gif
post #685 of 4784
smile.gif sucks for people buying Achivia ..go CATLEAP! seem like catleap is the better deal..97hz+!!! thats almost freaken 120hz monitor for free!

holy crap i am glad i stumbled across this thread. i ordered a Dell U2412M for $300 yesterday but I was getting an estimated delivery of 3/20.

Found this thread and immediately cancelled my Dell order and just placed an order for the Catleap Q270.

My dream monitor is essentially this monitor but 16:10 AR. I never expected to be able to get such a high resolution for this cheap...for $415 shipped I'm not going to complain. The added resolution over the Dell makes up for the weaker AR for sure.

I'll be posting when I get mine in the mail.

just got the achievia. VESA mounting was important for me. I have a tripple monitor stand(supposed to hold 3x 20-24in monitors) so I will just put this in the middle and my current 23.6 asus on one of the sides vertically for web browsing. should work nice. So becuase of that im not worried about the stand. the refresh rate also isnt that big a deal for me, since ive only ever used 60hz. so if i can get a little higher, yay? if not owell, hah. Today is friday so prolly wont come till next week, but when it does ill give my opinion on it. Had my monitor for...going on 4 years ish so i figured it was an ok time for an upgrade!
new toys, yay

60hz vs 97hz ...you will notice your computer ((seem)) to move smoother. That's what I feel when I switched from 60hz to 75hz..

See picture of mounting screws at the bottom
how long are the screws? Is it possible to insert a small washer on the right side between the base and the stand to "offset" the tilt?

The catleap was confirmed a few hours ago buy Toasty to have vesa mounting holes. They are just covered out of the box:

"It does have VESA mounting holes in the back, but it's covered by that gray plastic which you have to break off to access them. The gray plastic was already breaking off out of the box, so I might as well remove it since it serves no purpose. The rest of the monitor is intact."
