I really love benq blur reduction, I want a different monitor but I can't see them giving the same experience and benq hasn't brought and as far as I know, isn't bringing out new monitors for awhile still.. wanting something like IPS with blur reduction magic..

I just played some TF2 on the 4ms IPS and was experiencing some very mild motion sickness. The constant blur when running around on a small map and spinning 180 degrees to prevent backstabs started to give me some very mild motion sickness. It's like being drunk where your vision is smeared until you stop to focus on something. I can't see IPS doing well with any game that requires you to change directions quickly (FPS) unless it has a blur-reduction like the Acer XB270HU bprz or ASUS PG279Q (both g-sync monitors unfortunately). My Trace Free setting is at the recommended level of 60.

This is actually pretty surprising given almost every 4ms IPS owner on the internet swears 3ms wont matter or won't be noticeable to anyone who isn't a professional gamer. I hate to use the term fanboy-ism -- since at the end of the day we all love video games -- but that must be what it is. I would guess they haven't used comparable TN and IPS monitors side-by-side. There is a difference and it is definitely noticeable (in my opinion).

That feel when my i5-3570K is struggling with 1440p TF2 because the source engine is so CPU dependent. 390 at 51C... rolleyes.gif

EDIT
Also if I understand correctly, given the way blur reduction blacks out the screen for so many milliseconds per frame, I would expect an IPS to be much dimmer than a TN for the same "low blur" performance. An IPS won't finish forming the image until the last 2-3 ms of each frame display. Please correct me if I'm wrong.

Yes you're wrong.
An IPS would have more "Strobe crosstalk" than a TN due to slower pixel transition times, while a TN would have more "overdrive artifacts" due to often too aggressive overdrive circuits (though good TN's have more adjustments). But keep in mind that most Gsync monitors do not allow you to adjust the overdrive settings in ULMB mode so you're stuck with what they give you.

I can't explain strobe crosstalk here but what I can say is crosstalk is seeing the next (or previous, depending on WHEN the strobe signal begins or ends during a refresh (strobe phase, which most monitors do not allow you to change) frame superimposed on the current frame, because the pixels haven't transitioned their colors fast enough (the data from the previous frame) by the time the next frame data is sent to them. Both TN and IPS panels will have strobe crosstalk. The reason why ULMB doesn't work at 144hz refresh rate is not because it CAN'T do it, but because crosstalk would cover literally half of the screen!

OLED's would have absolutely ZERO crosstalk. CRT's have ZERO crosstalk as their response times are in the nanoseconds.

Older versions of the Benq blur reduction monitors allowed you to "extend" the vertical blanking period via custom resolutions, effectively cutting crosstalk by as much as 33%-90%, although this probably makes no sense to anyone here. But think of having the strobe crosstalk from a 2560x1440 monitor, and resizing the entire screen so it fits on a 1920x1080 monitor, so the 'remaining' crosstalk from the 1080->1440 vertical area is literally cut off and not visible.

The dimness from single strobe blur reduction is based on how long the monitor backlight is blanked out or turned on during each refresh, which is the pulse width timing. IPS or TN doesn't matter here. The strength of the backlight itself is what matters.

CS:GO gamer here getting ready to join the glorious 144Hz master race. My BenQ XL2730Z is being delivered today, any suggestions on how I should set it up from the experienced peanut gallery here?

Okay "CS:GO gamers"...

Can we talk about this screen and how it fits to CS:GO?

There is one thing that annoys me a lot - and that is, that all low resolutions get upscaled to 1920x1080 if 120 or 144Hz is chosen.
And this, on a 2560 x1440 display.

This means upscalling 2 times: additional blur, additional latency!

Or am I wrong? Why can't I have modes like 1024x768 or 1280x960 or 16:10 like 1280 x 800 at high frequency via DP?
And if it wants to upsacale, why not to native 2560x1440.

I'm no pro and by god I don't have any intention of playing at those garbage resolutions they play at for the sake of having fat player models. I don't have $1800 in skins to make them appear like crap on screen. Hell I don't even want to go under 1440p to 1080p, much less any of those 4:3 god awful resolutions pros use.

Then maybe get with the times and use 2560x1440? All this constant spam and harassment about 1024x768 and people upgrading their monitors to use ancient resolutions gets annoying. Fast. Like why bother buying a new monitor if people intend to use ancient resolutions? Just use the OLD monitor for crying out loud.

This will be the last time I ever comment on ancient resolutions anymore. But for 4:3 at 1920x1080 sized monitors, you can create a 1440x1080 custom detailed resolution in ToastyX CRU at 60hz, then use GPU scaling for the higher refresh rates (this is good for benq blur reduction 1.0 Z series monitors using VT tweaks to lower crosstalk for blur reduction while keeping their 1920x1080 VT tweaks active). use the video card control panel to select 1:1 or fullscreen.

for 4:3 2560x1440 resolutions, create a custom detailed 1920x1440 resolution at 60hz and use GPU scaling for the higher refresh rates and the video card control panel to select 1:1 or fullscreen.

if you want a display scaled 1440x1080 or 1920x1440 resolution instead of GPU scaled (for those who complain about 2 frames of added input lag or some crap because they can't awp with 8 ms of input lag), create a custom detailed resolution at the exact refresh rate you want, e.g. 1920x1440@120hz or 1440x1080@120hz (you can't do this for 144hz, you will need to use GPU scaling or deal with it). Then you will have a display scaled 4:3 resolution but it will be locked in fullscreen because the monitor OSD will not allow you to select 1:1, if the vertical size matches the native vertical size! There are 2 ways you can try to get around it (maybe):

1) change the vertical total (VT) value to a slightly lower amount until the 1:1 option in the OSD becomes available (this may or may not work or may cause strange things to happen)

2) change the active vertical size from 1440 to 1439 or 1080 to 1079.

Its a CS:GO related thing. Most pros play at those 4:3/stretched/black bars resolutions because it makes the player models appear fat/wider on screen. Making it feel easier to target them and it also makes it easier to engage enemies at long distances.

The problem is when i try to play CS GO in Deathmatches or Casual, the FPS vary from 80 to 140, and its not fluid as it should. I tried with, and without freesync (of course with DP connection, and 144mhz chosen on windows). Dumb down the ingame video settings to the minimum, and still almost the same FPS's everytime.

My GPU is a MSI R9 390, and my CPU although not that powerful, is a Phenom II X6 1055t, which i would assume, would be more than enough to have FPS's >144 in CS GO with very low settings.

Another big diference i saw ingame with the new monitor, is that when i access video settings, it hangs for a few seconds, sometimes gets a black screen for 1 or 2 seconds. It also happens when i apply any new change. I hear the click sound repeating itself a few times, then after a few seconds, its ok....

Any thoughts?

thanxs in advance,
Luís

What operating system are you using? If its Windows 7 then there are two hotfixes you may need to install. Making sure Windows 7 isn't randomly parking your cores. Read this: http://www.tomshardware.com/answers/id-2065810/amd-8350-quad-cores-unparking-cores-win.html

These are the Windows 7 hotfixes:

https://support.microsoft.com/en-us/kb/2646060

NOTE: THESE TWO HOTFIXES ARE ONLY FOR WINDOWS 7 USERS. WIN 8/8.1/10 ARE NOT AFFECTED

@Falkentyne

I did not ask you in specific any question, plus I already know the things you wrote there. I already used custom 1440x1080 on my old 1920x1080 screen and promoted this online.

Why should me or others play CS:GO at 2560x1440 including the official best CS:GO player (according to hltv) who uses this screen?

I buy a 2560x1440 gaming!!! screen because I want this space - at the desktop and maybe some games. But a user can decide on a game by game basis, which resolution to use.

What I asked in my post was, why that screen does this weird double upscalling! Simple question, right?

@Falkentyne I respect your kowledge, but as annoyed as you are of my question, one might be by your CONSTANT placement of your "blur reduction" "VT tweaks" "crosstalk" agenda over various forums where it makes no sense.

Right, so I got the monitor and I just got it up and running. Praise jebus no dead pixels but I do have a solid white line one pixel wide on the right side of the panel. I can only assume its the backlight. Either way its only visible if I am in full screen on a solid black image. Doesn't bother me as I never see it. So my question then is what should I use for color calibration as that is the only thing that feels supremely off right now.

Also when I turn on blur reduction the screen dims and it appears to me as if the image appears more pixelated. Don't know how else to describe it. Never used a monitor with blur reduction so is that normal? Granted I just went from a 4K panel whose pixel density is high to this panel that isn't as saturated so I don't really know how it should look. All I know is that when I played CSGO, good lawd, the smoothness was off the charts. Going from 60Hz to 144Hz is clearly noticeable.
