1. The VG248QE uses PWM. It either scales with the refresh rate (6x) or older versions only go up to 360Hz which is utter garbage. Even at 864Hz it's still objectively inferior to PWM free dimming. Older versions of the BenQ XL2411T also used PWM, but can't even find those anymore because the newer versions are the same price and better and the XL2411Z is also the same price and far better.

2. The colours are bad and in Lightboost they'll make your eyes bleed. Unless you think RGB works fine with just 2 colours. RGB coverage is fine, so if you invest 200$ in a colorimeter, instead of getting the XL2411Z which is the same price and comes with better colours out of the box or get a 500$ monitor which will be far better than either, and then spend 3 days calibrating it the colours will be ok.

3. See #7. At 350$ in Canada the VG248QE is a terrible deal and it's hard not to beat it. Because the XL2411Z is still better, hands down, and goes for 330$. http://ca.pcpartpicker.com/product/GbNp99/benq-monitor-xl2411z

And that's just one monitor, there's others as well.
tl;dr
VG248QE:
pros: none
cons: all of them
Fuck that thing.
