BenQ XL2411Z Is this normal? [Solved]

[tangelo]

Hello. I just bought my BenQ and I'm trying to adjust the settings for my liking.

So far there has been many problems like all the blacks are very bright and grayish + there is very annoying ghosting (or crosstalk?) while playing some games like Diablo3. The game actually looks better without the blur reduction, but it's a pain to always adjust the settings as the brightness goes up huge amounts when disabling the blur reduction.

Anyway, I've tried to use the VT trick but having an AMD card I've needed to use the toasty's app for it. I can't really see any difference with the VT enabled or using the "normal" resolution.

I'm asking you people, is this really the best this monitor can offer when Blur Reduction is on and VT trick applied at 1080p@ 120Hz? Override is on, Persistence is at 2ms and Crosstalk is at zero. AMA is HIGH, Instant Mode is ON




Any input and tips would be really welcome.

PS. Is there a way way to make a different settings for Blur Reduction and certain brightness vs. Blur Reduction off and different brightness that I could change via couple of inputs on the monitor's buttons, not having to need to browse all the sub directories and such? Also I haven't figured out how to load those settings I've saved in "Gamer1" etc. If I browse the different Picture modes from the menu and choose Gamer1 it's nothing like when I saved it...

Thanks.

I can't speak for XL2411Z, I have XL2430T, none of those issues you said exist on mine.

Maybe you need firmware upgrade v2, what browser are you running the test on?

Noticed this too while playing Diablo with 120hz/144hz. Everything on the screen "stutters" or become blurry while you move except your character, it doesn't matter if its up/down, or left-right. Item name labels become slightly unreadable if you move too.

There is a solution to this, but it requires an NVIDIA GPU: http://forums.guru3d.com/showthread.php?t=393714

I think this is the game's fault and not our monitor, more on this: http://us.battle.net/d3/en/forum/topic/ ... ?page=2#22

Not the monitor, to me is a double image effect when the game FPS drops near half of your Hz.

ie.
144Hz with 72FPS or lower
120Hz with 60FPS or lower.

My monitor has the V2 firmware.

I run the test on Chrome and always check that the test gets properly synced. I don't think it's a problem with the test nor my browser.

EDIT: Good info about the Diablo matter on that url, thanks gamerscore.

Judging from your screenshots, looks like the VT tweak isn't working.

You should not have ANY crosstalk thick double image at the bottom of the screen at all, and with the VT 1500 tweak, only the very top should have a crosstalk zone (if you use 1.0ms or lower persistence, it should be almost off the screen).

Your screen looks like a stock screen without any VT tweaks.

Can you post the timings in CRU.exe (custom resolution utility) that you have for 120hz and 100hz?
Can you post the pixel clock MHz that it says?

Did you run 'restart64.exe " (toastyx experimental driver restarter)? (you don't need to reboot the computer after running the toastyX pixle patcher or making VT changes or adding resolutions).

Forgot to add:
IF you're using the VT 1500 tweak at 120hz, which I DO suggest you use, please use the 24" compatible monitor timings:

120hz:
1920x1080 resolution
Front porch 48/3 (default is 88/4)
Sync Width 32/5 (default is 44/5)
Horizontal / Vertical total 2080 / 1500 (default is 2200/1500)
Using the defaults at 120hz will push the DVI way too high at 396 MHz, the screen will show corruption.
Pixel clock should show 374.xx mhz.

For 100 hz:
1920x1080:
front porch 88/4
Sync width 44/5
HT/VT: 2200/1500
Pixel clock should be exactly 330.00 MHz (this should not require the pixel clock patcher, but if you did masterotaku's 1502, it will, as you will be JUST higher than 330.00).

If you get problems with the 100hz showing out of range or something, then use the same values for 120hz: 48/3 front porch, 32/5 sync width, 2080 HT, 1500 VT, that will put you at 317 mhz.

I followed the instructions on the http://www.blurbusters.com/benq/strobe-utility/ -page so I haven't tried using 1500, only 1350.



Here is the list of resolutions available from windows settings. Pardon the Finnish language.



I don't know what you mean by "pixel clock MHz" I hope the info is available on the cru screenshot.

I did run the restart64.exe and even tried rebooting the computer. Didn't notice any change.
For me the problem is that I'm unable to check anywhere if the VT tweak is "on" or not. Only my eyes, and like I said, I really can't see any difference :/

I edited my above post.
Change the edit for 120hz to match the values I wrote. Make sure the pixel clock says 374 MHz after you do it.
Add 100hz for good measure. It doesn't hurt. I prefer 100hz anyway because its easier to maintain 100hz than 120hz in some games, and also ghosting when strobing tends to be lower at a lower refresh rate (lightboost worked like this; 100hz looks cleaner than 120hz)

BTW while you're online before you reboot, can you go into the monitor OSD While you're at 120hz right now, if possible, and tell me what it says your current refresh rate is (in System->information?)

When I first got the 2720Z, I also thought the VT tweaks weren't making a difference. Took me awhile to figure out that they weren't even working in the first place. I found out when I entered the 374 MHz 120hz VT 1500 timings and 120hz completely vanished from the CCC. Originally it had 336.96, but it was using the defaults as 336.96 is close enough to the dvi limit of 330 to not vanish as an improper resolution. When I had 396 MHz the first time, it (120 hz) vanished and only 100hz worked.
Then I realized the pixel clock limits were never patched, and this time I saw a massive difference in crosstalk at 100hz and 120hz showed swimming pixels (396 MHz is too high). When I lowered the porch and sync values and used 2080 horizontal total instead of 2200, 120hz went to 374 MHz and VT 1500 worked fine.

Since "display mode" aspect settings become unusuable with any VT tweaks, might as well use VT 1500 whenever possible

I need to go AFK for an hour or so, but I'll report back when I return.

EDIT: The monitor OSD says Current Resolution 1920x1080@120, same with Optimum resolution.

[Falkentyne]

Sounds good.
If you have any problems with the 120hz timings, try 100hz and post a screenshot (remember with my timings your pixel clock should show EXACTLY 330.00 MHz at 100hz).

Then in your testufo screen, you should have no thick bars at *ALL* at the bottom. You should see some regular ghosting at the bottom but nothing like the blurry crosstalk mess you had before. I can't do testufo at 120hz because internet explorer only goes at 67 fps (known issue) so I do all my testing at 100hz.

Hint:
If your monitor OSD shows 60 hz, you did the VT tweaks correctly.
If the OSD shows 100hz or 120hz, it's not using the tweaks and is using the default resolution settings.

Edit 2:
Just like I thought: the Vt tweaks aren't being used at all. I had the same problem originally.
Please try redownloading the ToastyX patcher and use the 1.3 patcher version.
