There is a slight clouding effect like with the Dell but since I got this Acer cheaper at Amazon I will keep it because this fact mitigates this particular flaw. This dark clouding effect seems to be quite a common problem with tft lcds. I checked several other monitors around here and most of them have it in one or the other intensity. I think I take a look inside of an old one and see what it is just out of curiosity and maybe try this or that to see what helps and what not.

The ulmb mode of the XB271HUA uses a more aggressive pixel overdrive than the dell. In ulmb mode I can see a ghosting effect on color transitions from bright to dark, for example from from white sun to the blue sky. because of ulmb this is not easy to capture on video without getting strobe artifacts. these are not visible in normal or gsync mode.

Another difference: the dell has a good power efficiency. at 35 brightness: ~25W, acer same brightness: ~34W

I have a question regarding a correct G Sync setup. I searched internet on the correct usage of V Sync with G Sync and it seems to me that every person says a different thing.

Before I ask a question, I'd like to state two things based on my understanding. Please do correct me if I'm mistaken.
1. You only get 1/2 of frame rate *if* rendered frame rate cannot keep up with monitor's refresh rate. Eg. 144 -> 72 -> 36 -> 18
2. G Sync is inclusive of V Sync.

Based on the above points, I've been using G Sync set up as follows:
- In-game V Sync option = disabled.
- NVCP V Sync option = disabled.
- NVCP G Sync option = enabled.
- Frame rate limit to 144 FPS. (via RivaTunner or nVIDIA Inspector)

However, searching the internet, there also are many people who claim that V Sync in NVCP needs to be enabled for G Sync to work correctly. confused.gif
Hence, suggested settings from those people seems to be:
- In-game V Sync = disabled.
- NVCP G Sync = enabled.
- NVCP V Sync = enabled.
In this case, I guess there's no need to set frame rate limiter.

Can anyone shed light on the correct G Sync setup ??

With that being said, there are exception for games like CS:GO where I can maintain constant 128 FPS almost all the time. (CS:GO's maximum tickrate supported is 128Hz) In these cases, I opt for ULMB rather than G Sync.
For games like this, I've been using the following settings:
- In-game V Sync option = disabled.
- NVCP V Sync option = disabled.
- NVCP G Sync option = disabled.
- NVCP ULMB option = enabled.
- Frame rate limit to 128 FPS. (fps_max 128 cvar)

It's written on the box with S/N, manufactured date etc.

For me i always see my NVCP vsync going back to enabled, it doesn't seem to ever want to stick on disabled for long. That said i think the best thing to do is leave Vsync enabled in NVCP, limit fps of games to around 135fps, anything closer to the 144fps cap of gsync will start introducing the input lag associated with vsync. With a 135fps cap you'll be playing with vsync off levels of lag. And of course leave vsync disabled in games always. Also ULMB adds some input lag as well, so for CSGO you may not want to use it if you're hardcore competitive, otherwise the amount it adds is negligible. Ideally really for a game like CSGO you just want to not use gsync or ulmb and let the fps hit its uncapped 300fps cap.

It's my understanding that this is the correct setup, and you can either enable vsync in-game or in NVCP, with NVCP being the better option. Frame limiting will prevent you from going into full vsync and possibly causing input lag. You should also test your frame limiting because it will usually allow some wiggle room, so setting it to something like 138 might actually be necessary to prevent going over 144.

What does the box say and do the serial numbers match one another on the box and behind the monitor? May 2016 should definitely be A02 or A03.

Whoops! Im an idiot! For some reason I jumped to a bunch of conclusions in my head about it saying Rev A01, when it clearly says Rev A03 on the box. I had overlooked that little slip on the side as I thought it was shipping stuff. It said Rev A01 on on some piece of paper in the box, but I guess that was incorrect! Sorry for the stupidity!
