Just talked to toastyX.
The reason your resolution is working is because it's not 1920x1440. Its 1920x1080, GPU scaled to 1920x1440. that's why you have a 1144 vertical total and that's also why your resolution you created in in the Nvidia control panel doesn't show up in ToastyX CRU when you open it. GPU scaled resolutions don't appear in CRU.
The only 1920x1440 resolution that you can create that is an actual resolution is 100hz refresh rate with a 1502 vertical total. And I'm not even sure if the older T series monitors will work with a vertical total that high. The Z series can use higher vertical totals because it improves the crosstalk of blur reduction mode. I'm not sure how the T series (Not the XL2430T, but the XL2420T / XL2720T) responds to VT tweaks though.
Question to BenQ XL2720T users
Re: Question to BenQ XL2720T users
Thanks, and sorry for being a bit late (I was on holiday). I ended up sending the 2720T back because it uses PWM for the backlight. The eBay seller had put this incorrectly as being flicker-free (the 2720z is). I loved it while gaming (100% brightness) but somehow my eyes felt worse than with my old monitor when browsing the web (30-50% brightness) without me really knowing why. PWM was the reason, and I used the phone on my camera to confirm that it does use PWM.
In the meantime, I got the Philips 272G5DYEB / 00 for quite cheap. It's also a very nice monitor, no PWM, and has the benefit of G-Sync. However, as far as I understand it, G-Sync only makes much sense when your FPS are below your refresh rate, and actually introduces input lag in CS:GO. I have not been able to confirm nor dismiss this claim as I have not been able to tell a difference after approx. 1 hour of testing each, at ~200-250 fps ingame. G-Sync does look quite good in GTA V however (50-90 fps).
The fact that my graphics card renders the 1920x1440 resolution might explain why the Philips immediately worked at this resolution as well.
It also has better image quality than the BenQ, but its stand is a lot worse (wobbly, less flexible) and it has a terribad OSD, no hardware profiles or quick switch like the BenQ does. It has a blur reduction mode (ULMB) but as with the BenQ the image is simply too dark even at the brightest setting. Some articles wrote about a crosshair function but I just don't have it on my model, customer service says it should be there.
So I'm not sure if G-Sync is worth the premium for a monitor at the moment. The 2720z might be better after all because it offers much better customisation (and it's 70€ cheaper than the Philips), while having PWM-free backlight over the 2720t.
It's a real shame the 2720G isn't going to be released, because it has everything I'm looking for.
Meanwhile, BenQs newest offering the 2730 only has FreeSync. Damn you, Nvidia!
