Benq 2720Z no difference in blur reduction?

[Falkentyne]

Open a text document in windows notepad.
When you use the mouse to scroll the notepad around, is the text smooth?
If it is and the browser isn't, then it's a browser problem.
Maybe check windows visual preferences (in system) or if aero is disabled (but testufo requires aero) or browser hw acceleration.

1) it's not, it's very blurry, i cannot read it even if i move it just a little. I don't think it's browser related. I have Aero turned on and i'm sure hw acceleration is on. On this page http://www.testufo.com/framerates-text on 'vertical test' I can clearly see text in the left window, so i see big difference between 120 and 60fps, but in practice in any word document or any browser, everything is blured if i scroll it. I also see very visible ghosting effect. The only place where it works as it should is this ufo test page. I'm on 120Mhz on desktop with settings set as you told me in this thread.

2) I also have another question, how should i define 144Mhz mode? Because for example Sleeping dogs doesn't allow me to use any other Mhz than 144, and based on your recommendations i only added 100Mhz and 120Mhz in CRU. 144 is undefined, meaning it's with default values. should it stay like that?

[Falkentyne]

144hz isn't a standard refresh rate. it's an overclock; no monitor can currently use 144 hz with standard timings. 144 hz uses reduced blank, and thus you can't use a VT tweak on it. It will go out of range.

I have NO idea why you are getting blurry scrolling. I can only see that happening at 85 hz and under refresh rates, where single strobe "off" sets double strobe. But 86+hz will always single strobe (but having single strobe "off" causes some minor bugs on 2720z, with strobe settings not always being used right away).

I think i will return this monitor, ask for refund and buy normal one. I don't see any reason to spend twice amount of money for exactly same quality. Blurring/Ghosting in games was never a big problem for me, it is not that annoying on standard 60Mhz. And blurring in Windows is exactly the same on 120/144Mhz as is on 60Mhz it seems. The only place where i can see the difference is in this specially designed test (ufotest). not in real life unfortunately.

but thank you for your help anyway! i learned some stuff, thank you for your time and advices.

P.S. unless you could recommend me another monitor? i have AMD card, so maybe i should wait for freesync?

[Falkentyne]

Waiting for freesync is a smart choice.
Look at the 2730Z...

Please, stop saying "MHz". We may be centuries or milleniums away from 144000000Hz monitors .

To stay on topic: if motion blur isn't a problem for you, freesync will be good for you, as Falkentyne said. Everyone likes minimal input lag and tear-free smoothness. 1440p IPS Freesync monitors are coming very soon.

sorry, of course it's Hz

as to newer freesync monitors, i'm just a little worried that 1440p is a little too much to keep 120fps (or 144fps) in games. I have amd r9 290x, and according to many reviews it's not that fast http://www.tomshardware.com/reviews/rad ... 650-8.html

for example arma III gives 66fps in 1080p and only 46fps in 1440p, other games are slighty faster but not many (if any at all) can be played with 120fps in 1440p. But i guess there will be no Benq 1080p 27" with freesync...

i could buy second 290x card but well... one quite modern card should be enough for gaming, it was expensive enough. the only monitor already annouced with 1080p and 144Hz is ViewSonic VX2701mh. What are your experiences with ViewSonic? Never had one.

P.S. http://www.trustedreviews.com/viewsonic-vg2401mh-review 6/10, it will be very similar to that one i'm sure... not really encouraging

What are possible reasons to get a brightness pulsing malfunction? I frequently have the phenomenon of ~1Hz pulsing in brightness levels, very pronounced on when displaying brighter colors. I have V3 firmware, VT tweak, 120Hz, blur buster anti-strobe, pixel clock patcher (happened the same with and without PCP). It's worked fine before but now I get this problem.

different directX games cause problems? I get on reboot now too.

Failing HD 7870?

What VT value are you using?
Some values are incompatible at certain refresh rates. Incompatible values will cause pulsating/stuttering/freezing in the monitor scalar.

the "Lightboost" (high) VT tweak range is 1497-1502. This uses accelerated scanout (increased vblank interval) equal to Lightboost.
But some values will cause pulsating backlight (stuttering frame sync error) at different refresh rates. There is no difference in visual performance in crosstalk reduction between 1497-1502; they all do the exact same thing, but you must choose the correct number per refresh rate (requires testing).

At 100hz, VT 1354 is ok, VT 1350 is NOT. VT 1500 and VT 1502 is ok.
At 120hz, VT 1500, VT 1499 is ok. VT 1502 is not (sometimes works sometimes pulsates)
At 125hz VT 1497 is ok.
At 91hz (e.g. Call of duty 91 fps games) VT 1498 is best.
At 85hz, only VT 1501 works.

I was using 1350 at 120Hz, it worked great for awhile.

So you're saying 1500 at 120Hz should work better?
