XL2411Z - How to set up VT 1500

[Falkentyne]

I did not apply the Nvidia pixel clock patcher - No idea where to get it from

But I managed to apply a VT of 1500 and it seems fine (I am getting a lot of ghosting in this though http://www.testufo.com/#test=ghosting - the bottom image almost has 3 layers but maybe this is just the monitor) Do I need the nvidia pixel clock patcher - I didn't see it in any of the guides

the pixel clock patcher is mentioned in the how-to in the guide on the main website!! like at the beginning!!! How do you say you never saw it?

I followed a guide on youtube not on here

I did apply the nvidia pixel clock patcher afterwards but I don't think I needed it as I was able to set VT tweak in the nvidia control panel

Your ability to apply a VT Tweak in the control panel has NOTHING to do with it 'working' or not working!
The VT tweak will not work (the custom resolution will be ignored by the driver and the defaults used) if the pixel clock patcher is not working (thus=darker screen).

The VT Tweak will still be SHOWN....it just won't be used. You can even enter invalid values like 1600 VT.

The easiest way to see if the clock patcher is working is to check the OSD information. if it reports "60hz" when you're at 120hz. it's working.

VT tweak is working

It's the ghosting I'm really annoyed with now you can even notice it when scrolling down web pages - Anything be done about this ? Any settings in service menu

This can only be improved on the XL2720Z V4. Benq (for some reason no one knows) did not include the new AMA low (Lightboost type setting) on the 24" monitors.

The only thing you can do is drop the contrast from 50 to 40. This will only improve certain color transitions/boundaries by a small amount, or use Lightboost mode and deal with the washed out colors.

If you are on Version 4 firmware, you can go to AMA, highlight high and if it's already on high, press whatever button on XL2411Z is "back" (left). This will lower the AMA intensity by about 5%, which will be less of an effect than lowering contrast from 50 to 40, but will affect all transitions. It's not much but but well... (note: this didn't work in V2 firmware).

Or you can use Lightboost mode, which has much lower overdrive intensity (uses per-line overdrive and nowhere near as aggressive) and looks 10x better (but you lose all gamma and color control).

While all of the 27" monitor's lightboost mode have higher ghosting artifacts than lightboost mode on the 24" monitors (E.g. comparing the Asus VG278 and VG248; the VG278 exhibits more ghosting in lightboost, as the 27" monitors tend to keep a much higher static contrast ratio in LB mode while the 24" monitors drop to <450:1), but can be improved by lowering to 0 contrast), the Benq XL2720Z has what appears to be an undocumented "lightboost" type AMA setting for Blur reduction mode, which (at low contrast) has the same lightboost overdrive level (which we can call AMA low; turning on MBR and setting/toggling AMA to high afterwards will reduce the AMA intensity by about 50%!) and will be identical if you compare both LB and BBR both at contrast 0 (with the exception of per-line overdrive not in BBR mode and needing a VT tweak, while lightboost has a built in VT "Tweak" (LC panel update/accelerated scanout) automatically).

It's a shame that this new AMA setting was not included on the 24" monitors. It may have been a test for the XL2730Z or something...

i have persistence on 2ms

is this to much
