Yamakasi Catleap Monitor Club - Page 226

Well, that's a pretty tough proposition. We'll start with the easy ones:

-HDMI is definitely out, as it's pretty much like a single-link DVI. You're not going to get enough bandwidth out of the port.
-It would be technically possible to produce a VGA converter capable of doing this, but it's highly unlikely that the RAMDACs in your system are good enough to drive it. Additionally, nobody bothers making such a thing (because the analog hardware required in the converter to interpret a resolution that high is very expensive, and it's such a niche market as to basically not exist)
-USB is a possibility, with the caveat that that's a *lot* of pixels to be driving over the 480mbps allotted, even compressed. If you *do* find a USB video card that supports such a high resolution, image quality (due to compression) or framerate will suffer.

So... you don't have a lot of good options, unfortunately. Is a docking station available for your notebook that might have a proper dual-link DVI out?

Rightly or wrongly, this gives me piece of mind that I didn't pay extra for nothing.

If anyone can read Korean, see the sticker in the picture.

interesting how it has the Chinese character:



on the sticker (meaning none). Didn't think Korean used Chinese symbols at all anymore.

Just got mine, took 3 days to get to my doorstep in Seattle area. No bright pixels or dead pixels.

The stand seems fine, doesn't wabble isn't lopsided.
post #2255 of 11285
Mine just showed as shipped. I hope it comes in with no dead pixels or dust in the panel.

That would be a wrong assumption that you paid extra and got something tangible in return. Would you have gotten the exact same panel if you had not gotten the perfect pixel garuntee? Quite possibly.

The reason why I think it is a scam lies along these lines --> Manufacturer has 1000 monitors, of which 10% of them have some sort of stuck, dead or hot pixel. What does the manufacturer do? Sell them all for $100 each. Each $100 000. One dude has a bright idea! Sell the "perfect" ones as "perfect pixel" monitors for more! Let's say 100 people bought the perfect pixel ones for $200. Everyone else buys the normal ones. Manufacturer, with the same stock has now made $110 000, and all they needed to do was to brand them slightly differently. The base models have now decreased in value, but they still sell them at the same price. The perfect pixel ones they've charge a premium for, when people would ordinarily only have a 10% chance of getting some sort of defect anyways.

But what happens when people catch on? Oh, but you need the Pixel Perfect one 'cause everyone else is getting it, and if everyone gets it, then the chances of you getting a defect is higher since all the good ones were taken! So everyone buys the perfect pixel version. The manufacturer just sends out what they made, defects and all. Some of the people with bad monitors complain, they refund some money and take some losses in returns. Meanwhile, they've increased their revenue by 90% (and profit by FAR more) and they haven't improved anything as far as the quality of the monitors are concerned. They've managed to charge $200 for ALL of the good ones, and the bad ones they've managed to sell for the base price. And everyone that got a good monitor thinks they got their money's worth, when in fact, all that has happened is that the manufacturer has made a ton more money off of basically nothing.

In this particular case, it's an even bigger scam; there's no conceivable way we'll return these monitors. People aren't going to return defective "perfect pixel" monitors, which is the worst case scenario for the manufacturer. Now, the worst case scenario is that people demand a refund for their perfect pixel extra cost, and so they gladly return the money. They've managed to charge a premium to those willing to pay it, and those who've paid it don't really get any benefit from having paid it at all.

In the end, once this reaches equilibrium, only the manufacturer benefits from this perfect pixel policy. Everyone who bought the perfect pixel ones are happy because they got what they wanted, except they paid more for what they might have gotten without paying for it. The people who have to buy the non-perfect ones aren't happy because they, through no fault of their own, have been screwed by people who are willing to pay more (and thus the incentive to pay more increases in a positive feedback loop) and the manufacturer is ecstatic because they made a bunch of money from essentially nothing.

Basically,
1. if everyone played the pixel lottery, then everyone would have had a 90% chance of a perfect panel. The manufacturer makes normal profits.
2. If everyone payed for the perfect pixel garuntee, then everyone would have a 90% chance of a perfect panel. The manufacturer profits big time.
3. If only a small set of people pay for a perfect pixel garuntee, then those small number of people get a benefit, and everyone else is screwed. The manufacturer profits more than the base case.

3) Solder a 0.1 - 1 micro-Farad capacitor to the free end of the resistor in step 2.
4) Unsolder diode #704 and put this diode in place of resistor #725 (220 Ohm). White striped cathode will be on the right relative to the picture.
5) Connect with a wire the capacitor from step 3 to the left terminal of the empty diode terminal #704.

I took a closer look at the area shown in the picture on the boards I have; it would appear that the board photographed is a 2C variant, or it at least has a backlight driver section that matches my 2C and does *not* match the 2B board (the layouts are slightly different).

Can anybody reporting backlight unevenness list whether they have a 2C or 2B variant please?

I just get my 2B catleap SE (without speaker) today, I am located in Busan Korea so i get it for around 265,000 krw which is around 250 usd
It is not a steal, it is a rob!

I am in my lab now and I try it with my lab PC(just i3 and gt430m) and i got it to 97hz
just using the nvidia control panel custom resolution, as easy as a pie
When i get home later i will try it with my 2600k and 560ti
hopefully can boost pass 100hz

Anyway, my catleap is also leaning to the right side
i rmb i saw some1 posted the same, he use some plastic waste cup to stack up and hold the monitor from leaning to the right
any1 else the same? how to solve this in a better way beside buying a vesa mount?

450
for reference, this is my 2B serial number, u may also note that the orange color sticker on the top, it say zero defect version, i got it for normal price instead of premium price!

Hey guys. I posted a new video on youtube that offers further proof to the 124hz claim. The interesting thing I found, though, is that the actual vertical refresh rate is unstable at 32 bit colour because of the heavy bandwidth requirement. I did some calculations on a website as well that, well, anyway...the video will explain. So what I had to do was create a more stable 124hz environment, so that with the reduced vertical refresh limit @32 bit colour, would still put out 119-121hz, which is exactly what a standard 120hz monitor would display at something like 1080p!

Cheers.

Edit: And yes, as usual, I'm video taping my sessions using my iPad. So it's still 1080p...but not the greatest 1080p. And it's super shaky. I gotta find a better way to do this. tongue.gif

mmm they look great... would a gtx580 with 1596mb be enough to utilise its goodness?
