I thought I'd drop my 2 cents since researching a monitor can be really hard and it might help some people some time.

I own those monitors long enough to draw some conclusions. My s2716dg is from early 2016, it's the first revision. My xb241yu is from late 2017 and it's the bmiprz version. So let's go one by one, form most to least important in my opinion.

Colors on both monitors:
When it comes to color banding, s2716dg is clearly inferior. It has no factory calibration while acer has several gamma presets to choose from, and none of them produce any significant color banding. It's marginal on the acer but very pronounced on s2716dg. Acer has built in saturation control, so you don't have to do anything through nvcp. The acer also has more color regulation options (not only rgb, but also yellow,magenta and cyan levels).

Acer clearly wins here unless you have a color calibration device.

Gaming:

Acer is a 165hz monitor, while dell is 144hz. Both support ULMB, but Dell in ULMB mode is just too dark even at 100%. Acer has no problems running a bright image in ulmb. In g-sync mode, both have excellent pixel response time and the image in motion is razor sharp, but dell very clearly has more color artifacts in extreme mode, while on acer it's well within the limits of acceptable and goes unnoticed most of the time. You have to put the s2716dg is the normal response mode, which gets rid of most overshoot but you can see more blur and slower pixel response.
Xb241yu has the osd setting for displaying refresh rate number and different aimpoints, while s2716dg has none of those features.

Overall, in fast motion, acer feels faster and more accurate with colors while also having the features I mentioned above, which I use all the time.

Another win for acer

Image sharpness and size:

Dell is bigger, so it makes it better for browsing the internet. I wish I could say that about videos too, but color banding really lets you down here, therefore I prefer xb241yu for movies and videos. In gaming, the image produced by xb241yu is sharper and there's less visible aliasing due to higher dpi. Dell is quite sharp too, but in some games you can clearly see some aliasing.

Build quality:

The build quality is fine one the dell and has good height regulation. But the acer feel more premium here too. It feels much more sturdy and well built, it has height regulation and full pivot. When I try to shake my desk the dell get wobbly too, but the acer does not thanks to excellent build quality and firm feet. On the xb241yu you'll also find a big spike protruding out of the back, which looks badass and is great for hanging your headphones.


All in all, I feel like s2716dg could have been sooo much better if they had spent more work on the osd, which is ver,very basic. Acer wins the osd options comparison by a landslide, and that's mostly what makes the xb241yu a much better display overall. It's an impressive little monitor for gaming, I can't even find one weakness for the acer. When I had s2716dg only, it felt great, but after 7 months of running them side by side, I clearly see s2716dg has a lot of shortcomings in comparison to xb241yu. I felt like the difference is big enough to write those few words for you.

When it comes to build quality - Dell all the way, but in this case Dell 2716DG has the wrong build, because it is meant for gaming, yet it's build like an office or studio monitor, and the Acer is specifically build for gaming. However, that Dell 2716DG was a big disappointment, just because how bland it's colors are! I came to realization that all that NVIDIA G-SYNC stuff, 144 Hz refresh rate, 3.5 ms input lag and 1 ms black pixel reaction time are less important than pure color quality!

Depends, it'd take 144hz, g-sync and speed over colors any day. I had mx27aq before s2716dg but got rid of it pretty quickly. Fixed 60hz is just bad for gaming, and I can't live with ips glow and backlight bleed in every corner. Dell stomps it for gaming purposes despite the fact that it does have flaws.
Most of the blame,like I said above, comes from bad factory calibration and weak ass OSD. XB241YU has the same 8-bit TN panel but colors are saturated and there's a lot less banding.

Dell has some excellent value for its price despite some flaws.

Pros
1.Often sell at $350 for now. (I paid mine for $500 year ago).
2.1440p G-Sync 144Hz ULMB.
3.Excellent response time. Probably one of the fastest TN monitor in the world (by real measure not some bullshit number *cough* 1ms *cough* claimed by manufacturers).
With 2.8ms average and 4.5ms highest. Even most of 240Hz monitor cannot match. Exceptionally for ULMB that need fast response time.
4.Color is good when properly calibrated.
5.Dell use light anti-glare coating unlike ASUS / ACER on their 1440p 144Hz counterparts.
6.Can combined G-Sync + ULMB with unofficial method.
7.Dell on-site service.

Cons.
1.Color banding !! This is major flaw for me but I found some workaround method to deal with it. But now the method no longer work since 397.31 and Nvidia will not fix it for me so I have to accept slightly banding.
2.Slight overshoot when scrolling sites with grey background and black text. But this is unnoticeable in games or other sites.
3.Deep sleep bug. Have to disable it. Not a big deal for me.
4.No gamma setting in OSD. Probably the banding will be much better if Dell include it.

Yeah, it's a beast for gaming. The ULMB brightness bug is really a deal breaker though. It's too dark even at 100% brightness in ULMB mode.

What is your brightness in normal mode ? Mine is 26 and that is very close to 100 in ULMB.

26 is way too dark for me. 40-50 is what i like.

Thank's for your inputs enterprise24, those were really on point marks to think about.

Illuminosity-ghosting in overdriven TN's is a given and you should have settled for ULMB - that won't be much different from the in-motion calibrated gamma level.
2716 is a good display. Make no mistake about it. All displays above an unspecified tier run into some form of tonal overshooting. The setup for in-motion calibration would look pretty undersaturated and the setup for still pictures would, again, bleach all gradients. There is no magic bullet except for making separate setup profiles, though TN pixels would still oscillate at switch periods. You could make adjustments to LCD timers to take a look how it responds. Normally longer blank intervals should settle the gamma for longer pans every frame but that would burn more display pixel clock - limited by the video adapter interface bandwidth, pretty much.

frame synchronisation is a lot more important to me than minor overshoot.


btw, don't I know you from ocn.net ? I remember someone with the same nickname.
