Here is my ghetto solution for the catleap stand problems:
catleap-cups.jpg
The stack of cups evens out the monitor and stops it from wobbling. It actually works quite well. Whatever you wedge under there needs to be about 10.5 cm tall.

Also, here's my catleap's backlight:

The bottom right is a little bit brighter, but it's fine otherwise. There is no edge bleeding.

The panel is the same, but the controllers are probably different. This particular panel is directly driven internally by a DisplayPort signal, so something has to convert dual-link DVI to DisplayPort. The catleap seems to have a very simple controller that accepts whatever you give it and sends it to the panel. It can't handle non-native resolutions at all. The shimian's controller might not be as simple, or their particular implementation might not be able to handle higher refresh rates.

I contacted ST when we were posting these questions - way back in the thread - and they said it would be covered based on the FAQ. Of course they could say no later on, but it was enough for me to order my Catleap with the warranty. thumb.gif

I mentioned on another forum that I found this:

http://blog.naver.com/PostView.nhn?blogId=shinchkr&logNo=20125954902

Its a complete teardown of a Crossover with clear shots of the board and driver chips. I like the Crossover the best of the 3, so I'm hoping one of the ebay guys starts selling it. Otherwise I'll look at using a shopping service. Anyway I thought someone smarter might be able to make sense of some of the pics. I mentioned on the other forum that it appears there are solder points for a DSub connector, not sure if you could just solder a DSub or component RCAs on though.

I believe that is the power light.

I have sent an email to Dreamseller asking if he can stock the Crossover as that is the one I am interested in because it has a good stand. I'll be sure to let you know what his response is when I get one.

Does the glow increase if you increase the brightness?

Anyone here from CA, Los Angeles and ordered these monitor and its been "locked" up in "inbound custom" for like 3-4 days already? God mine still showing "inbound custom" .. sucks
post #940 of 4784
so i suppose im confused a bit, ive read through the majority of the posts here and over at {-}ardforums and these monitors looks great albeit the catleap might jump out at me more lower problems it seems and non tempered glass.

I really want to buy this however the biggest thing holding my back is the unavailible OSD controls?

im coming from a 24in hp lp2475, and it had quite a bit of control as far as brightness, contrast, color temp 6500k & 9300k. From reading all these posts i believe the only thing you can control on these monitors is the brightness correct? if so do we know what the native color temp is? and how might this effect our ability to customize our own color presets.

I know this is a good deal regardless i just want to weigh my options! thanks guys!

Also im confused ive heard of people getting non tempered glass Achieva's. Are these just rare? i think my biggest thing with Achievas are the dust between the glass.
