Got an Acer Predator XB241YU, turned out to be faulty... Also in general I didn't like it either, it had a lot of glare, 24" is a bit small... So it got returned.
Looking for a new one now.

What's everyones suggestion? My budget is likely about $600ish. I'm mainly wanting to use this for Battlefield 1. I'm not sure how well my System will handle all games in 1440P/ Ultra, I'd like to get at least 60FPS but I'm unsure if the 1070 can do that for all games. It might just be my experience with BF1 and its incredibly poor optimization. 

I NEED a Gsync monitor, that is very important. I'm unsure if the 144hz is necessary to be completely honest. For web browsing and watching TV/ videos, most videos are native at 1080P/60hz... When I had the Acer Predator it had problems running with another screen, standalone I saw 0 difference running that screen vs a 1080P 60hz for web browsing/ movies/ videos. 

Specs:
i7 6700k
EVGA 1070 FTW 
16GB Gskill TridentZ 3200mhz
ASUS Z170 PRO
EVGA 750W G2
Samsung EVO SSD


Thanks!

Dell S2716DG here. Great monitor and fits your budget.

Wooohah
Thanks guys! 

I was considering the ASUS ROG monitor like Sajin said, the difference between that ASUS ROG and the Dell mainly is going to be the panel type right? I believe the ASUS is a IPS which has better color, and the Dell is a TN which may be a few ms faster?

And either of you run a secondary monitor just for general browsing that's a lower resolution or lower refresh rate? 

The PG278Q is a TN panel. The PG279Q is the IPS one (for about $100-150 more). I love my PG279Q although IPS glow is something you'll have to get used to. (NOT backlight bleed...there's a difference)

Yes I run the S2716DG and a 4k 60 Hz samsung monitor as secondary. S2716DG is indeed TN but has the best color and viewing angles of any TN I have used. The ASUS ROG are very nice as well.

If you've been exposed to IPS technology, it's really hard to go from IPS to TN.
The same can be said for 144Hz > 60Hz.
 
I initially upgraded two ASUS PA238Q monitors to two BenQ Zowie XL2430's. The BenQ monitors were nice but they were TN panels and it was something I just couldn't get past. Things looked washed out and viewing angles felt extreme even slightly off. I loved 144Hz though and going back to the ASUS PA238Q IPS screens was hard because 60fps now seemed choppy!
 
I ended up returning the XL2430 monitors, which were great but I'd just been accustomed to IPS for so long it was impossible for me to be happy.
 
That brings me to recently, at this point my requirements were:
144Hz
IPS
 
I found that this combination is actually particularly rare, where the only options are;
Acer Predator XB271HU
ASUS ROG PG279Q
 
Both are 144Hz/165Hz OC + IPS Panel + G-Sync + 1440p
 
These are both £600-£700 monitors so it was a big investment but it felt like the only way it would feel like an upgrade.
 
After reading reviews/videos of these two monitors I decided to go with the ASUS ones as it seems like the build quality is a step above Acer's and the way you interact with the monitor was better (joystick on back). Also since I will have them mounted on a Vesa stand, I could get rid of the ASUS ROG branding, but this was not the case for the red predator logo on the Acers.
 
Bare in mind though, with both of these monitors - it is a lottery as to if you will get a good panel. The Acer seems to have a slightly better average of a good panel but I'm not of current quality control issues. When I get mine, if it is bad, I'll return it and reorder another. Amazon is amazing with returns.
 
If I was you I'd either;

• One of the ASUS 27/1440/TN/G-Sync monitors. (BenQ ones do not offer G-Sync)
• The SG Dell monitors that are 27/TN/G-sync/1440/60Hz+
• Or save a little longer and make the full upgrade that will cover you for years to come (IPS/144Hz+/1440/G-Sync) Where 1440p will probably move to be the standard, where 1070s+ can run fps exceeding 60 so you'll want the extra Hz to see them, the G-sync for fluidity and 27 inches for that slightly bigger screen you're after.

 
 
 

Its not so much not being able to afford a better monitor, its just so much as seeing if its honestly worth spending so much.
I've always used a TN panel, and I think i've always used 60hz as well so I don't know what an IPS panel physically will look like.

I'm seeing that i'll pretty much be spending at least $700 for a 1440P/144hz/Gsync/IPS monitor, I'm kinda wishing I'd gotten a 1080 initially :/
I'll likely go with one of the ASUS ROG ones, it seems like generally those are the best out there and what most people run.

The thing is I might likely have to get a 1080P 144hz or a second 144hz monitor to run alongside the 1440P that I get. I've heard that running a 144hz and a 60hz monitor as a secondary monitor can lead to terrible stuttering. Not sure if you guys have any suggestions there, i'd be just for browsing, no need for anything pricey, I may even just go for refurbished.

What do you mean by lottery if I get a good panel? Do you mean like dead pixels? Or the monitor just not functioning properly out of the box due to QC? 

Thanks guys 

You can still run with vsync on even if you're not pegging your FPS at the refresh rate.  With a Gsync display, I find using vsync on the best.  It will maintain the refresh you use (if capable), yet when not, runs very smooth.  No tearing or stuttering.

You want V-sync turned off in game when you use G-sync, turning on V-sync will interfere with G-sync and basically turn it off. You can have V-sync on in the NV control panel but want it off in game for sure.

Yes, setting vsync for the each game profile in the NVCPL (vsync disabled in-game) is the way to go if you choose to use vsync.  And it works flawlessly using Gsync.  No stuttering, no tearing.  I should have been more clear in my post above.

Yeah I'll probably have to go into a store and compare. 
I've always run with a TN panel and i'll be honest... I find the colors a bit washed out. Like for whatever reason whenever I watch gameplay videos on youtube the color of the explosions and fire is very vivid the colors are very vivid and pop out.
But with my TN panels they just kinda seem a bit... washed out or greyer. 

I'll probably go see the IPS panel in person and see how much of a difference it makes haha, but i'll definitely probably be getting one of the ASUS ROG monitors. 
I'll probably be doing a bit of photo editing in the near future, so I believe an IPS panel will help with that. For me a huge thing is color accuracy and picture quality being clear. Some people say IPS has a pretty big noticible difference, some people say there really isn't :/ I think its probably just up to the person/ monitor, so i'll take a look at one in person.

Thanks guys :^) 

Yeah, for example the DELL S2716DG looks rather abysmal out of the box, colors are low saturation and gamma is way off. But once calibrated, it's a rather beautiful display.
