Why has there not been any talk about this? Unless I'm understanding this article wrong this monitor is the first to have blur reduction working at 144hz. Asus ROG Swift PG278Q, Acer Predator XB270HU, earlier BenQ monitors etc. only have blur reduction at max 120hz, no?
Is this THE monitor to get for competetive gaming at the moment?
BenQ XL2730Z has blur reduction working at 144hz(?)

no, with all the crosstalk it would look (I believe) even worse then 120hz.

I see, but why do they have a picture like this:lexlazootin wrote:no, with all the crosstalk it would look (I believe) even worse then 120hz.
and then say "The image was slightly cleaner at 144Hz than at 120Hz due to the higher frequency of the strobe."
Though in that pic it looks like the blur reduction at 120hz way looks better...

Um, The Benq XL2730Z just came out.
You do know that the OLDER Z series monitors (XL2411Z, XL2420Z, XL2720Z) also had blur reduction working at 144 hz, right?
The problem with 144 hz blur reduction is the strobe crosstalk. You can't use vertical total tweaks at 144 hz because 144 hz won't even work with normal timings anyway; it uses reduced vblank timings--which is why video cards won't downclock while idle at 144 hz. So using a VT tweak is impossible.
100 hz and 120hz both support increasing the vertical total from 1125 (the default on 1080p screens) to 1500.
It's currently UNKNOWN if the XL2730Z supports vertical total tweaks, and if it does, only 100 hz and 120hz would work with it.
It's also possible that a 100 hz vertical total tweak with XL2730Z would "fix" the reported out of sync strobing at 100hz in the tftcentral review. One person said he was able to use a VT tweak but the screen went out of range after a value (forgot if he said 2000; remember this is a 1440p panel). But no strobe crosstalk was tested comparing VT tweaks to without VT tweaks yet.
I PM'd the reviewer of the tftcentral 2730z review to see if he can test VT tweaks if they improve the bottom area crosstalk (assuming strobe phase=000 / Area =000).
About the picture:
That picture talks about overdrive ghosting during blur reduction.
Strobe crosstalk due to the monitor not completing a gtg transition during a vertical blank period is a different problem, and that crosstalk is exactly what the poster above you is talking about. (since 144 hz can not use VT tweaks to improve the crosstalk).
VT tweaks increase the vertical blanking period time, btw (by increasing the vertical total value).

Are you saying that a GPU can't work at e.g. 50% of its capacity if you play an old game on say low settings running at 144 hz/fps. The GPU will stay hot and consume 100% energy?Falkentyne wrote:144 hz won't even work with normal timings anyway; it uses reduced vblank timings--which is why video cards won't downclock while idle at 144 hz.
