1920x1200 should be fine via single link dvi, but lets let an actual owner of one of these chime in.

#### LagunaX

Think u need dual link dvi cuz my hdmi only gave me 1920 res.

But it worked right? I don't want to dismantle my current Windows computer and put together the Hackintosh only to not have a monitor to use it with. As long as the display still works, albeit at a lower resolution, I'm fine.

Hey guys, I have a quick question. I know that this monitor requires dual link DVI in order to display the full resolution, but will it display 1920x1200 if connected to a single link DVI port? I've yet to purchase a video card with dual link DVI for my Hackintosh, and the motherboard only has a single link DVI port. Would I be able to use the monitor at all? My motherboard manual says that the maximum resolution output from the DVI port is 1920x1200.
No. If the monitor has the "multi input" with an HDMI then yes, it will display at 1920x1080. Single link DVI doesn't work and the single input models.

I think it depends if you have scaler in the screen or not.
If the screen has HDMI/VGA ect then i think it will work but i can't be sure as i don't have one with those inputs.

When i tried with mine (only has the DVI) it would not work with a mainboard that only had single link DVI.

Bingo, that's what you get with the multi input versions.

Now my Catleap Q270 is not displaying image anymore. I unplugged the DVI cable from my 2win card, to check my sr-2 folding rig time per frame, but when i switched back to my main rig, it just refused to work.

I plug the power brick in the wall, little green light appear on it. Now plug the brick into the monitor: red light on it for a few seconds, then either a) i don't plug anything else, the red red starts to flash on and off ; or b) i plug a confirmed working dvi cable coming from a known-good running rig to see the light stop flashing, turn green, see the screen power on (it turns from the no power black to more led like black. I think you get what i mean. Up to this time, my usual desktop would appear and that is the way it behove since i bought it back in last August), see the screen go off after half a second, and watch the light return to red-flash state.

I had a guy at work (the electronic technician we call when our many-hundreds-thousands $start going crazy) open it up and it confirmed that there is power in it and the problem seems to be in the little pcb in it. Could this be bought anywhere? Contacting the seller led to being asked to ship back to korea, wich would cost in the 400-500$ range according to my estimator. That is not going to happen.

I'm asking here in hope of finding people who have gone through some trouble with their screen, and what exactly could be the option of a canadian fellow when things go sour...

I say thank you to the TPU community in advance, as i know this place (the whole tpu forums) is just awesome.

Only solution I know of would be to take it to a TV repair person. I have one with a bad PCB on it as well.

It's worth a try. Did you get yours repaired?

Man that sucks and fear of such is a main reason I don't have one of these already.

Open it up and post a well lit picture showing the caps on the power PCB

No, not yet. I bought a new Shimian for now.. and it's much nicer.

The best i can provide is the pictures the guy emailed me. I don't have the skils and tools to tear it apart.

Just wanted to confirm that the monitor does NOT display any output when hooked to a single link DVI port. The power indicator flashes green, but there is never anything on the screen. I've been thinking about downgrading to a 1920x1200 24" monitor since 27" is way too damn big anyway, I should take this as an opportunity to do just that.

Has anyone looked into getting the 30" 2560x1600 versions of these monitors?

If only my KVM didn't support up to 1920x1200. *le sigh*

I remember seeing catleap has a model awhile back, but it was \$550 or so at the time.

Yeah these seem to be the "latest thing" out of Korea now with more and more popping up from various sellers. If you are really looking for more info and experiences (and not just potentially that of TPU members) then head over to the various busy threads at overclock.net.

#### DOM

anyone picked up one of these Korean 27" screens off ebay ?

so there has been some Yamakasi that just stopped working ?

My Yamakasi works just fine.... had it for several months now. Looks like Erockers shit the bed though.

OCN has a monster thread on these, not sure if any died there or not. But loooooooooooove mine!

Me too.

Even with the shitty stand, it's still miles better then my old monitor.

Erocker had problems with his?? Didn't know: sucks

Yeah he uses a Shimian now I think.

erocker broke his Catleap when he took it apart to replace the stand, it wasn't so much a defect with the monitor as it was just misfortune and probably poor design. I took my Catleap apart to replace the stand and darn near broke it myself, the bezel was impossible to pry open. Even beyond that, the fact that you have to disassemble the monitor to install a VESA stand is ludicrous.

I should mention that my perfect pixel Catleap sprouted a stuck red pixel a few months into my ownership... but it seems to be a rare occurrence.

#### DOM

Okay so the ones I'm looking at are good then ?

basically they're all the same screen just different housing brand name?
