Do you happen to know if the monitor is receiving 133Hz or just the limit of the graphics card? And does it play well with the games at that refresh rate? And if you don't mind to upload the monitor .inf of this 133Hz?

Thanks

The highest I actually use to "Play" is around 124hz because it's fully perfect without any issues even after extended periods. Why 124 and not just 120hz? Well..as we go up higher, it has trouble actually putting out the refresh rate it's supposed to. For example, a 120hz display will put out 119-121hz. But this monitor, set to 120hz, will put out 115-119hz. So by going up to 123-124hz, I end up with an active 119hz-121hz.

And yes, the refresh rate will act and behave properly, IF you follow the OC guide in my signature below. Otherwise half of your games will revert back to 60hz when you play them. The limitation, even at 537mhz pixel clock didn't come from the card. At that refresh rate, your horizontal refresh rate is at 199khz. It's the 200khz which is the limit (I'm assuming from the PCB...because even at 200khz...that's ridiculously high. lol). But realistically...running a 60hz panel at nearly 222% of its stated specifications is scary. It follows the standard rule of Overclocking. Find your maximum OC, then bring it down a bit for long-term stability.

As for the inf, I already mentioned going through my youtube guide linked in my sig! There is a downloadable package in the video description that contains all tools and drivers, along with video guidance on how to use them. So don't worry about anything. Just get your hands on a B series monitor and you'll be set. wink.gif


I was thinking about 3 identical screens but if we are not forcing the refresh rate thru the drivers will have issues. What do you think?

Well the driver I've provided lets the computer think the monitor is capable of handling 120hz just fine. So that shouldn't be an issue. You should be able to run 3 at 120hz no problem. Assuming you have 3x dual-link dvi ports.

17. April UPDATE

Sorry guys! I haven't been watching the thread closely the last couple of days! (lack of updates)

Last thursday, I was told that they would have a second meeting with witech(the manufacture) friday!
Unfortunately (since we are 11 hrs apart in timezone) I didn't catch him friday or monday!

But i did get a quick word from him today!

They are comming!!

Once again everyone agreed that this will be made, they are currently working on a webshop system. where you will be able to buy the monitor!

As soon I get any more updates on specs and price, i will let you know.


Added to OP aswell.. along with HyperMatrix 100+ hz guides! Thank you alot for making them!

Okay, as per Ken's request once again, I'll clear up some misinformation regarding cable bandwidth and monitor refresh rates:

My message to Ken:

KK, did some number crunching for you. The effective data rate of a dual link DVI cable is 7.92 Gbits/second. With this in mind, the highest resolution dual link DVI supports at 120hz is 1920*1200. How do we know this? 1920*1200 = 2,304,000 pixels, 2304000 x 120(hz) = 276,480,000 x 24(bit color) = 6,635,520,000 or 6.63 Gbits/sec.

For a resolution of 2560*1440, lets do the math:

2560*1440 = 3,686,400 x 120(hz) = 442,368,000 pixels per second x 24(bit color) = 10,616,832,000 bits per second or 10.6 Gbits/second.

Dual-link DVI effective data rate = 7.92 Gbits/sec
HDMI 1.3/1.4 effective data rate = 8.16 Gbits/sec
DisplayPort 1.0/1.1 effective data rate = 8.64 Gbits/sec

2560*1440 @ 120hz = 10.61=Gbits/sec which is well over all of these.

Displayport 1.2 effective data rate = 17.28 Gbits/sec
HDMI Type B effective data rate = 20.40 Gbits/sec

Those would work with 2560*1440 @ 120hz

From the write up I did, I would hypothesize that the hardware is indeed pumping out 2560*1440 @ 120hz or greater, but the bandwidth is being exceeded and the monitor is is not showing many of the frames. Just like when you're gaming at 120hz yet you have a 60hz monitor, you're missing half the frames the hardware is pumping out.

So if that's true - and that's some pretty good math. That means that 120hz is not really a reality on these monitors? Rather people are getting over 60hz, but nowhere near 120hz. More like the exact point that bandwidth runs out?

Or is it possible that the refresh can be pushed beyond the effective rating? (Yes, I am ignorant in regards some specific things - yes, I understand this)

I dunno man. I notice an actual difference going between 100hz and 125hz. In the testing I've done, when I'm running it at 120hz at 16 bit colour, I get (as reported by refresh tester in powerstrip) 120hz. If I jump to 32 bit colour, however, the limitation kicks in to play and I get 115-118hz. I compensate for that by running it at 124hz, which at 32-bit colour, gives me my roughly 119hz-121hz. And even this is only possible after the cable has been warmed up. Off a cold boot of the monitor, I have to start out at around 106hz. And only as the monitor and cable warm up can I start switching to higher resolutions. And this happens on a very linear progression.

I should probably add that cable quality does come into play here as well as the limitation being referred to is moreso the copper cabling, than the dual link dvi interface, as the interface is technically capable of 9.9Gbps, and some higher quality cables claim to be able to actually do the full 9.9Gbps.

And as I like to call it..."I'm OVERCLOCKIN COPPER, bleepwords" tongue.gif
