Benq XL2430T Settings

Its more expensive and I don't really care about the display port or s switch

I did have the 2411z before and it was good but it was returned due to stuck pixels - is easier to set up than the 2430t

I know but the problem is DVI is starting to get phased out. As you know the Radeon FuryX doesn't even come with DVI ports, and once you let the hardware genie out of the bottle.....you know...... Even Gsync monitors (which don't apply to you) are DP only (although newer revisions will have HDMI 2.0 ports at least). Plus do you REALLY want to keep going through the monitor menus to change profiles when you can press 1 button externally to do it? I mean you can set customized key to "picture mode" and get to the list automatically, but after so many profile switches, it's a pain.

The display ports and the s switch would be nice but that would mean an extra £100 and I don't see it being worth that much

With the 2430t setting up VT tweak 1500 was really easy - Is it as simple as that with the 2411z or do I need to use other software as well

Its the same on all of the Z series (the XL2430T is really an XL2430Z. It just doesn't have lightboost).

The XL2430T has a fix that it can identify the correct refresh rate when a VT tweak is being used. The XL2420Z, XL2411Z and XL2720Z will report 60hz whenever a VT Tweak is being used. This is how you knew a VT Tweak was active --by checking if the OSD reported 60hz or not. This trick doesn't work (afaik) on the XL2430T anymore. At least not according to another person who tested that the VT tweak was ACTIVE and working (proof: the backlight shut off at AREA 60 / Strobe Phase 60) but the OSD reported 120hz instead of 60hz.

question:
Do you care about blur reduction and overdrive quality? Do the overdrive artifacts bother you?

[drakefive55]

I don't even know what VT tweak does but the only reason I liked it so much on the 2430t was because when blur reduction was on the screen wasn't very bright and the vt tweak made it brighter

Check the Benq section and go back in the archive or read the howto on the main page.
It explains what the VT tweak does.

By increasing the internal "Vertical Total" value while KEEPING the physical screen size the same, you increase the vertical blanking period, because the vertical size is increased. Internally, this forces the scaler to work with a larger "virtual" workspace, which has the effect of giving the panel more time to complete pixel to pixel transitions during backlight strobing. The result of this is it reduces the amount of "strobe crosstalk", which is a very thick double image, which is pixels in transition between strobe pulses. The image below this strobe pulse crosstalk (e.g. higher strobe phase value or higher "area" value in the OSD) actually has 1 lower frame of total input lag than the image above the strobe crosstalk. Using a vertical total tweak pushes the crosstalk boundary zone farther downwards (since the vertical total is increased, the workspace is increased so the crosstalk area is pushed farther down the screen).

The reason the screen becomes BRIGHTER is because when the panel is run out of specification due to vertical total tweaks, the "60hz" backlight pulse width "persistence" values are used instead of the defaults. The 60hz pulse widths are 0.167ms per point of Intensity / Strobe Duty, so on the Z monitors, strobe duty 001 is 0.167ms persistence and strobe duty 030 is 0.167ms x 30=5.01ms persistence.

Without a VT tweak its 0.1ms per point at 100hz and 0.08ms per point at 120hz and 0.07ms per point at 144hz.
144hz can not use VT tweaks but using VT tweaks at any other refresh rate (up to 125hz custom) changes the persistence to 0.167ms per point (60hz persistence values).

This is why the XL2411Z, 20Z and xl2720Z will report 60hz when using a VT tweak. For some reason the Xl2430T reports the correct refresh rate.

Appreciate you explaining that it makes it a bit easier

On the 2430t to do the VT tweak I had to do was create a custom resolution in my nvidia control panel and set a setting to '1500' would it be the exact same for the 2411z

I have an AMD card.
Should work for any monitor, regardless of brand, depending on its limits.

Hi Everyone,

I just purchased the XL2430t monitor (came from a 2420G which had a grey line, RMA'd) and have a very tough time trying to color calibrate and get this thing going for both desktop use and CSGO.

I have followed the above examples and had a few questions:

- The Strobe Duty and phase in the service menu are the same as the blur reduction area and intensity? (so no need to use the service menu)
- Single strobe is better to be on than off?
- Is there a particularly good overall configuration at 120hz (with or without VT tweaks) and 144hz?

I have been trying to set this up for a week now since RMA'ing the gsync monitor and feel I have made a terrible mistake (should have just kept the other). The colors regardless of how long I spend to calibrate, seem to be off (top of screen to bottom of screen seems to fade out) . Any assistance would be much appreciated and I thank you all for contributing so far in the thread. Its been a good read!

The new changes in the XL2430T simply seem to cause everyone problems. IF you don't like the results just get an XL2420G if you want to try gsync on an Nvidia card (in Z mode its 100% identical to XL2420Z) or an XL2420Z with the version 4 firmware (note that on the 24" monitors with V4 firmware, setting AMA to high *After* enabling blur reduction reduces the AMA intensity by about 5% (on the XL2720Z it's about 50%, which is much better).

If you want better overdrive through a hidden AMA blur reduction setting (less intense overdrive artifacts, much lower than XL2420Z/XL2411Z/XL2430T unless you are using lightboost mode (XL2430T does not have lightboost btw), then XL2720Z with firmware v4. Note that for Lightboost users, the 24" monitors ALWAYS have better (much less intense) overdrive in Lightboost mode than the 2720Z does. But only the XL2720Z has a new AMA setting that was thrown in by Benq on V4 without any notice and unfortunately it only applies to blur reduction.
