Yamakasi Catleap LCD

[Nathelion]

Did anyone else read about that Yamasaki Catleap LCD that people over on OCN are all gung ho about? Apparently they managed to overclock them to do 120Hz, which would be a first for 1440p AFAIK:

Since there evidently exists a panel capable of 120Hz, it hopefully won't be too long until we see 1440p panels retailing at that speed in the channel.

Honestly, you have to realize that it's completely out of spec. They are running the pixel clock way higher than specified, and don't be surprised if a few months down the road they brick the TMDS transmitter of the DVI port on the card. Concept wise it's nice, but in practice it's probably the most dangerous overclocking thing they are doing with their computers.

That resolution + refresh will only be available on Display Port, when it becomes available.

 

[Nathelion]

True - I'm sure there will be issues with that OC down the line.

However, isn't the bigger story here that there is fact exists an LCD panel capable of those refresh rates at that resolution in the first place? It should be a fairly small step for device makers to improve controller electronics and add DisplayPort to a monitor with this panel and be able to sell it as a 120Hz 3D monitor.

I'd always assumed that the big challenge with 120Hz was to get the panel to refresh that fast in the first place - it would seem that there exists at least some panels able to do that at 1440p now.

Have one and really enjoying it!

Hm. I wonder...

You have to realize that it's completely out of spec. They are running the [CPU processor, GPU processor, Memory Controller] way higher than specified, and don't be surprised if a few months down the road they [brick/burn out/degrade] the [CPU/GPU/Memory Controller].

Not saying it's not risky, but the TMDS transmitter is rated to 340 mhz minimum, beyond which is considered overclocking the TMDS transmitter. 340 mhz corresponds to a 85hz refresh rate on 2560x1440. Going to 100 hz (400hz, where I'm sitting now for gaming), that's only a 18% overclock. Mind you, this is the limit that Nvidia specifies in their 5xx series cards.

That most people have not even considered overclocking their monitors, that this is kind of uncharted territory, to be sure, that is risky. But is the TMDS transmitter especially susceptible to damage due to overclock? I don't see why it would be. I would think it has a similar kind of tolerance that most electronics have (whether or not it's useful/possible to overclock them).

Why did you post this ?

I could get into a 2560x1440 100hz IPS...

 

[bunnyfubbles]

I'd be interested, but 1080p@120Hz is already enough of a money sink for my hardware to try and keep 1920x1080 driven @ 120fps, it almost hurts trying imagine trying to feed 1440@120.

where is GK110 when you need it?

I love my 2209wa

uhhhh, what was that shiny thing that I just saw?
Curse you OP!!

I've been thinking about buying it too....lol

I'm running a 20/30/20 PLP setup right now and I'm getting really annoyed that I can't do eyefinity or nvidia surround. I'm tempted to ditch it in favor of three of these things in portrait. I would do 3x30" but that's just stupid money to be dropping into a machine that gets used for nothing but web surfing.

Buy it buy it buy it!

Just kidding. But for once, my impulse buy resulted in something quite unique. I don't think I can get a better LCD monitor on the market for gaming at the moment. And for $400. Unfortunately, it doesn't seem my setup can get 120hz; my monitor/video card combo maxes out at 116 hz. So close, yet so far.

I would temper any expectations of >60hz operation though; the vast majority of the monitors received have not been capable of > 60hz operation. A minority of users have gotten the correct internal electronics capable of driving 1440p @ 120hz.

That being said, 1440p 8-bit IPS monitor for ~$350.

Buy it! Don't think! I have the 3007WFP-HC and couldn't resist! I'm actually ashamed to say that I enjoy the Catleap more

I'm having a hard time finding a picture to verify, do these things use standard VESA mounts?

I have a parabolic arm that holds my current setup and will never go back to individual stands for multi-monitor setups.

Yes, they do. The Catleap requires some disassembly to get to the VESA mounts. The VESA mounts themselves are a little cheap, but they work. I've mounted my Catleap on an Ergotron MX monitor arm. The Catleaps are VESA 75mm.

 

[Viper GTS]

Hmm you're not making it any easier to not do it.

I've got this arm, should work nicely:

My current setup fits on it but it's absolutely the max it will do width wise.

I have one. Came with 4 dead pixels. The manufacturer changed out to cheaper components starting the end of February. As such, the newer versions don't 'overclock' past 62-67hz. Also it is a glossy panel, the reflections do get quite annoying in the day time.

 

[Nathelion]

It looks like some people at OCN are trying to petition the manufacturer to bring a limited run of the original (overclockable) monitor back. We'll see how that pans out. Without the OC it's more dubious whether it's worth it. It's still 1440p IPS at $400, but you don't get a warranty, the build quality/stand is craptastic, and there seems to be a comparatively high incidence of dead pixels.

If only it weren't for shipping. The base price is ~$230...

 

[arkcom]

There's also the Shimian for $325, and going down every day. They seem slightly worse than the Catleap, according to the OCN poll.

[bunnyfubbles]

yeah, there's simply no way I'd waste my time with one of these if it couldn't do 100+Hz

already have a Dell U2711 to complement my 120Hz 1080p monitors, there is just no way I'm going back to 60Hz for gaming

 

[bradley]

I had read anecdotal reports regarding these Korean LG-based monitors how overclocking above 70Hz does not come without dropped frames. I'm letting others be the guinea pigs and waiting for a further price drop before making the leap myself. I might just end up buying a few.

 

[Gloomy]

I have a Crossover 27" with the adjustable stand. It's pretty sturdy. Doesn't wiggle while I type like I heard the Catleap does, and I'm typing on a Model M so I really have to hammer the keys...

For what it's worth, mine is not dropping frames unless my video card is unable to keep up. I thought it was dropping frames when I was running 85 hz on a HD 5770, but that was just 'cause the thing was too slow at 2D clocks to push 85 hz.
