Benq blur reductionv s lightboost on a VG248QE
I play FPS games competitively and am currently playing on a VG248QE at 120hz with lightboost. I'm curious how this compares to Benq monitors with built in blur reduction. I've heard that BENQ monitors are basically superior to ASUS/almost all gaming monitors. What are your opinions? Does BENQ's built in blur reduction reduce brightness like lightboost does? Is it is effective as lightboost? How do you guys think the VG248QE compares in general to similar BENQ monitors? I'm asking all of these questions in relation to competitive FPS. I know some monitors are better for various functions, but I'm really just interested in what will make it easiest to see and track players in an FPS.

Re: Benq blur reductionv s lightboost on a VG248QE
The Benq monitors (Except the XL2430T which has 3d vision 2 removed) also have lightboost.
The 24" benq monitors have the same lightboost quality as the VG248QE lightboost, as the panels are the exact same model, and lightboost uses internal parameters for overdrive, bypassing both Asus Tracefree and Benq's AMA.
Lightboost mode on the 27" monitors is significantly worse than on the 24" models (this also applies to the Asus 27" screens also).
You may not know this, but the VG248QE's lightboost is much more adjustable than Benq's lightboost. Even though both look identical at default settings, you can improve Asus lightboost drastically to make it look almost perfect.
As you know, on this test on your Asus, which you can test right now, you notice there is some inverse artifacts and ghosting at the bottom of the screen, right?

Well, at the default contrast of 76 in Lightboost on the Vg248, the bottom of the screen looks pretty bad, right?
You can improve this somewhat by setting the contrast to 0. Try it.
Looks better, right? But you can still see some inverse artifacts.
Now, unlike the Benq, you can go in the service menu for the VG248QE, and adjust a value called overdrive gain.
And even though Tracefree is disabled (unchangeable) in lightboost mode, you can STILL change the gain!
The gain is linked to the non lightboost tracefree value, BUT they are NOT the same. Even though changing the tracefree value also changes the OD gain to the corresponding value (00, 03, 06, 09, 0C (12), 0f (15), changing the overdrive gain does NOT change the tracefree value. But lowering the tracefree value also lowers the gain, so there are two parameters at work here. The gain is accessible in Lightboost.
You can do a nice trick here. First let the monitor warm up for at least 1 hour (if it was off), then enter the service menu, while in Lightboost mode, change the OD gain to 0C and then exit and lower the contrast to 0.
Then compare the bottom of the screen:

Notice the difference?
it looks **perfect**.
And there is only a very very mild reduction in this perfect in the top. There is absolutely no other monitor or ULMB/overdrive setting that can match this. Test it out.
This can't be done on the Benq because there is no way to adjust any sort of overdrive gain through its much worse service menu (actually the factory menu, service menu#2, as service menu#1 has the benq blur reduction strobe settings, which have nothing to do with overdrive).
As far as comparing Asus lightboost to Benq lightboost (assuming both are at default=both look the same) and Benq blur reduction:
Note: Asus lightboost=Benq lightboost.
Asus lightboost trashes the contrast ratio even at default contrast, down to <450:1
Asus lightboost trashes the gamma curve and makes things more washed out. This improves a lot after the monitor has been warmed up, so this becomes a very low factor, but is really massive on a cold screen.
Asus lightboost trashes the colors and gives the picture a very 'cool' feel, almost as if the Kelvins are too high.
Asus lightboost locks you out of the OSD adjustments.
Asus lightboost can cause a purple tint to appear on what should be pure white, particularly at higher contrast.
Asus lightboost has VERY nice overdrive/ghosting quality (which can be improved even more on the VG248QE but not on the Benq Z).
Asus lightboost only works at 100, 110 and 120hz.
Asus lightboost has the minimum levels of "strobe crosstalk", with only a mild amount of crosstalk at the very bottom of the screen. The crosstalk level is so low that it needs no adjustments.
Asus lightboost overdrive ghosting quality is even better than ULMB (with the gsync VG248 module) or ULMB on the newer gsync monitors (if you can handle the horrible contrast ratio and muted colors, though).
Benq blur reduction works from 60hz to 144 hz in 1 hz increments, thus is far more adjustable and can run at odd, custom refresh rates.
Benq blur reduction with single strobe=on can work at 60hz for console/arcade emulators and 60hz/60 FPS locked games.
Benq blur reduction does not lock you out of the OSD settings; you have full gamma, contrast and brightness and color options.
Benq blur reduction allows vertical total tweaks via custom resolutions, to improve the strobe crosstalk (the default crosstalk is massive and too high), to make it very close to lightboost's crosstalk.
Benq blur reduction has much higher levels of strobe crosstalk at the bottom of the screen than Lightboost. You can use the "strobe phase" service menu setting to change the position of this crosstalk.
Benq blur reduction allows more adjustment of the persistence (strobe duty) which is like the "Lightboost 10-100" setting, except you can adjust it even lower than what 10% allowed, going as low as 0.167ms or 0.08 ms persistence for the most blur reduction (at 144 hz refresh rate, but you won't be able to see barely anything) up to 5.0ms (which is far too bright and worthless).
Benq blur reduction has FAR worse overdrive and overdrive artifacts and inverse ghosting than Lightboost--by far. Benq's AMA is simply way too aggressive. Only the XL2720Z with version 4 firmware has an extra hidden AMA setting which you can use to make AMA high (In blur reduction mode ONLY) equal to lightboost's internal calibration, but this also requires lowering the contrast, or the normal ghosting will be too excessive).
Benq blur reduction does not requires an Nvidia card, and can even be used on a console.

Where do you access the OD gain in the Asus menu? My vg248qe is almost 3 years old, i don't know if that changes anything.

Re: Benq blur reductionv s lightboost on a VG248QE
As I said, the service menu.
Yes it does change things. Even though the defaults are okay, lowering od gain from 0F to 0C (15 to 12) combined with dropping contrast to 0 makes the ghosting literally ZERO. The monitor should be warmed up 1hr + for best results.

Re: Benq blur reductionv s lightboost on a VG248QE
Sorry i should have been more clear. I meant to say does having an older vg248qe change the service menu? The reason i ask is because i cannot find a OD gain option in the monitors menu.

Re: Benq blur reductionv s lightboost on a VG248QE
It's NOT in the OSD. It's in the service menu.
Power off the monitor, hold the middle button + Power, release the middle button when the screen appears (the Asus logo should be bypassed).
