Hey guys!

Stumbled upon this thread today and I'm pretty excited.

I'm looking to upgrade and this couldn't have come at a better time... Although, the question is, Crossover, Achieva, or Yamakasi??

It seems there's quite a bit of models from gloss/matte, pixel perfect/non-tested, alternate pcb, etc.

I was wondering if anyone could recommend me one of these models?

I'm looking for a matte screen, preferably 100hz+ overclock-ability, and perfect pixels. Inputs doesn't matter. I'm fine with one DVI.

I'm hearing the Yamakusi is the one to look into. Any thoughts?

100hz+ models are exclusive, google it and you will find an alternate site where you can find those. I think all of these are glossy displays. Achieva or Catleap is the way to go. Some have reported dead pixels on models that were sold as perfect pixels on eBay....so its a gamble really.

Ah, thanks for the input.

I think I'll go for a regular, non-tested Catleap and just prepare myself to complain and send it back if it's severely flawed... Expecting the worst seems to work best for me.

In theory, if a sound cord is not plugged into an Achieva IPSBS, the speakers should be 'off' and not consume any power? I won't be using monitor speakers, but there's a seller who's substituting LITE monitors with IPSBS as a "promotion", and I'd like to know if I should message him and say that I don't want the substitution to happen. Any possible issues with having speakers in these panels? Like any buzzing and what not.

Ta-Planet has limited supplies of Yamakasi 120hz in stock right now. Not cheap however. I have a pixel perfect Shimian in transit right now.

Prad's Review of the Achieva Shimian QH300 is up, it received their lowest rating

http://www.prad.de/new/monitore/test/2012/test-shimian-qh300.html

Below is my interpretation

+Good Viewing Angles
+Good Screen Uniformity
+Good Pixel Response Times
+100% sRGB Coverage
-Typical Grainy Matte Coating
-Mediocre Contrast/blacks (700:1 only at the max brightness...30" IPS pretty much always have mediocre contrast)
-Contrast is greatly reduced when you turn down the brightness (450:1 after calibration @140cdm/2 which is horrendous imo)
-Have to keep the displays brightness cranked to keep the contrast around 700:1
-Over 1 frame of Input Lag
-Distorted 16:9 image (stretched) with external sources (consoles/blu ray players)
-Power Consumption

That review is for the 30 inch. Any reviews for the 27 inch?

I don't know why, but I had a helluva time finding the correct Power Brick for my new Shimian QH270-Lite, so to save the next paranoid guy the trouble, here's what you need to know.

The only issue when searching for a replacement power adapter / ac adapter / power brick / for the supplied 220v version is that anything you find on eBay is the wrong polarity (Pins 2 & 4 are positive, when you need pins 1 & 3 positive).

Before I found the correct power brick with 120v needed for us Americans, I purchased the following: Power Bright VC200W Voltage Transformer 200 Watt Step Up/Down 110 Volt - 220 Volt (http://www.amazon.com/gp/product/B000MW83OG/ref=oh_details_o00_s00_i01).

Then a few hours later, I found the correct power supply on eBay by chance (and this one didn't cost $300+ like the other I came across).

Just do a search for the following on eBay: EFL-2202W

This should return a couple Power Supplies/Adapters that are the correct polarity AND voltage for American use for roughly $23/each: http://www.ebay.com/sch/i.html?_from=R40&_trksid=m570.l2736&_nkw=EFL-2202W+

The Nanjing Frontek that came with my Shimian may or may not be of questionable quality based on other posts, but for that small investment for a new PSU, you can rest assured you're not sending the wrong voltage to your new monitor.

And my new Power Bright Step Up/Step Down Voltage transformer on the way? Well, it's always good to have one of those on hand since I have lots of friends always coming to stay with me from foreign countries, so I don't feel any regret for buying one of those too because I know it'll get some use eventually.

I hope this post helps someone that was in my same situation today.

Enjoy your pixels. I know I will.

Just wondering if anyone has gotten the Potalion with a mac, yet? I asked BCC and the seller said it is the same as the Shimian except the design is different.

Did you end up buying one of these for your macbook.

I just received the Potalion monitor today and hooked up to my 27" imac mid-2011 model, and all I'm getting is a black screen. The iMac seems to 'see' the display and allows me to choose the resolution and correctly lists 2560x1440 as the default option, but just getting black on the Potalion.
