144Hz monitor - yes this is a thing

If ASUS make this in a 23" format then I think I've found my next monitor.

It's too bad it's a 1080p 27" screen, the pixel density is far too low. I will be checking it out though to see if it's worthwhile or noticeable from 120Hz.

1080p kinda hits the bandwidth limits of HDMI when running at such high refresh rates.

I wish things would move on to DisplayPort's already!!!

I've heard conflicting statements on whether or not Displayport or something called Thunderbolt (I think) can do 2560x1600 at 120hz.

As for 144Hz, why? Such a seemingly random number and barely a step beyond 120Hz. Would've thought 240Hz would have been the next one tbh.

From wiki;
17.28 Gbit/s of effective video bandwidth, enough for supporting 4 simultaneous 1080p60 displays (CEA-861 timings) or 2,560 × 1,600 × 30 bit @120 Hz (CVT-R timings)


So if you had a dual link displayport adaptor, could theoretically get 35gb/s for 3840x2160 @ 120hz.

I think 144hz is possibly the absolute maximum for hdmi to handle at that resolution.

Those "200hz" TV's you see in the shop, aren't strictly 200hz. They generate "fake" frames between 100hz images to make it appear smoother.. that, among other things, is why they have such high input lag & aren't really 200hz.

I think you mean Dual Link DVI-D, no 120hz monitor that i've seen or heard of accepts 120hz through HDMI (It has enough bandwidth but it's used for Audio on top of the Video).

Things can now move to display port since both nVIDIA and AMD are now using them, previously only AMD were.

exe3 wrote:I've heard conflicting statements on whether or not Displayport or something called Thunderbolt (I think) can do 2560x1600 at 120hz.

DVI-D Dual Link = 9.9 Gbit (330 MHz)
DisplayPort v1.0/1.1 = 10.8 Gbit (360 MHz)
DisplayPort v1.2 = 21.6 Gbit (720 MHz)

2560x1600 @ 60hz = Bandwidth:8.75 Gbit (w/overhead) or 245.76 MHz.
2560x1600 @ 120hz = Bandwidth:17.5 Gbit (w/overhead) or 491.52 MHz
1920x1080 @ 60hz = Bandwidth:4.43 Gbit (w/overhead) or 124.42 MHz.
1920x1080 @ 120hz = Bandwidth:8.86 Gbit (w/overhead) or 248.83 MHz
Source, may not be right but they look close from memory.

Getting the most out of Dual Link DVI-D I suspect, no one else has done it and so it should sell somewhat profitably.

As above.

Interpolated frames, as you said processes your input and then ups that to 200hz, not an input/output of 200hz.
It's a good feature as it makes low resolution up scaling look much better (harder to see the pixels) and obviously much smoother, it will make distortions around fast moving objects sometimes though which detracts from the look.

It's actually a fun discussion topic, watch movies in there true frame rate (usually 23.976fps) or watch it with the interpolated frames which makes it look more 'lifelike'?

Thanks for clearing that up! Wasn't quite sure on exact details.

Might check this monitor out closer to release..

Wikipedia states that Displayport v1.2 has only 17.28GBit/s hence why i've been seeing conflicting statements.

I hate the 'fast forward' look of those but it seems to vary from screen to screen. I like when a screen can get the smooth motion without making everything look like it's set to fast forward.

Business Wire wrote:DisplayPort v1.2 increases performance by doubling the maximum data transfer rate from 10.8 Gbps (Giga-bits-per-second) to 21.6 Gbps, greatly increasing display resolution, color depths, refresh rates, and multiple display capabilities.

Display Ports DevCon Presentation PDF also states the 21.6Gbps.

It's an interesting effect, the audio is still in sync but you perceive it to be going in fast forward. I only remember seeing it when I first used a 200hz screen and I haven't seen it since.

Well with The Hobbit at 48fps, that will definitely be interesting to see in the cinemas. I might wait until DisplayPort becomes the big thing in monitors to get a 3D, until then my U2410 and its smexy colours are gonna stay :D

Im thinking of upping to a 680 with DP as im looking ata 120hz monitor and i dont want to rely on dl-dvi. HDMI is effectivly dying out in the computer/monitor field whilst its coming into mainstream with consoles and TV.

i have been using dp cables at work for the past 8 months, and the move to them has been worth it, but in the home space its only just getting there.

Is lovely to use! I've been using display port for the past hmmm, 3 years! Noticed most dell monitors seem to have support for it now days :)

Cheeky monkey,

So much easier to fit than vga/dvi for installations (did 500+ machines over the summer, booyah) plus with ivy now out and the IGP on the cpu means dual screens on our fleet (990's) when used with vga... most high end dells' have it, and i think 23's from the p2311 have had it...

hehe, yeh it had to be an rog product didn't it?
Overclock your monitor now!

no really, thats what i'm sure this is.... just an attempt to get people who have to have bigger badder **** than their neighbour's money.

The difference from 120hz would be minimal at best imo.

Nobody cares about a 10% improvement but this is 20% ... ... ... and that is advertising gold

The fact that it is along the lines of "New improved BLUE washing powder" isn't so important
