Dell S2716DG - Dells first G-sync

^ Have you tried going into the monitor options and turning off deep sleep mode?

yes mate all turned off now ..only the middle monitor was on off as i turned that off ages ago , i just dont want to see if they do go into sleep mode now in case i cant get them back out again . perhaps deep sleep mode on the screens has something to do with it will find out when i have to unplug all the screens to put them on a bracket .

enjoying them at the moment and cant even tell they are TN panels and games are so smooth . and better than the X34 i had .
 
In many cases the banding is actually present in the source material (i.e. game). That is particularly the case for fog or smoke, such as in Zavod Graveyard Shift. It's far less computationally expensive to render scenes in such a way that causes fairly abrupt brightness steps (i.e. banding) than to have a completely smooth transition, regardless of how good the monitor is. This can sometimes be hidden by having elevated gamma and is also exacerbated by gamma that is too low.

The native gamma of the S2716DG is particularly low and is obviously corrected in the centre of the screen if you profile. Depending on how extensive the adjustments are elsewhere, this correction can actually exacerbate banding in fact. Additionally, it is only correct at the centre of the screen, and as above 'correct' gamma could simply reveal inherent problems with the game itself. You may notice that the banding is less obvious towards the top of the screen?

Thanks for the reply. Honestly I don't really notice it on particular region of the screen but just in certain scenarios in game like where there is volumetric fog, clouds or just a shadowy area in a movie.

I did ask the author of Displaycalgui about where should a colorimeter be placed for calibration, as one blog said it should be where white level is closest to 6500c at the default out of the box settings (Part 5)
http://www.damiensymonds.net/cal_i1DP_pc1.html

However his reply was just to place it in the center, so I did my calibration from there.
 
They are better than the 1st 1 i had , they all do have slight cloudy banding but can only see this at night and a complete black back ground or at boot up .

my only problem is when the monitors go to sleep after a certain time that when they wake up when i move the mouse is that only 1 screen comes on and is a pain to get all back on , in some instances none of them will come back on ..when only 1 monitor comes on it goes back to sli (maximize 3D performance) and i ave to do the whole process again . this all then works , but if i mess with bezel correction all 3 monitors go blank .

Ive asked this question on another thread but to nobody knows whats going on . might ring overclockers and ask one of there guru's .

but when it works it works and my 2x980ti runs the resolution 7680x1440p brilliantly on most games on max setttings , Project cars i get over 100+ fps on max settings even with AA on and ultra grass .

only game to bring it to its knees is Crysis 3 where i get about 40-80 depending on settings , i get 80 if i take off AA and tone down a few settings like water and post processing down a notch . what an experience though . got dizzy at first when using them for first time , but the thing i can do now i.e play football manager in windowed mode and still browse the net and do other things on the other 2 screens .

















just need to get a good bracket now . as im very limited to where i want the screens as the right hand is way to much inwards and just a tad on the left , as i only want a slight curve and not a big one .

Amazing setup mate :):eek:
 
Anyone had problems with the displayport?

Came home today and the dell would just go to sleep, it didn't show up in nvidea controls but if i woke the monitor by re-selecting DP input the G-sync notification would pop up (2nd screen) but still state no signal.

While i sit here with no picture but not in sleep mode i can see the monitor in Device manager (not in display properties).

Eventually i turned it off and on again as the PC was booting and then it was okay again...

Sad note i manage to damage the bezel and mark the screen... as i tipped the monitor to check the cable I failed to notice I was laying it against the metal frame of my K65 keyboard....all because the DP failed to detect / be detected.

Yes, this is true, the banding is often the result of the source material. The game I mentioned above - Never Alone - has inherent banding which manifests across all the different screens I tested it on - IPS, TN, VA, Plasma and AMOLED. The difference really is one of degree but none of the panels were able to "remove" it completely. The S2716DG is simply the worst panel I have at "masking" banding. It's theoretically possible to address the source material through a dithering or debanding shader with Reshade/Sweetfx but this can be tricky and may introduce it's own problems. If I get a chance I might try Reshade in the next few days and report back.

It's very interesting that you mention this as I find that the banding occurs the further away you move from the centre of the screen. Now that I think about it I don't recall ever seeing banding at the centre.

I have found that if my PC goes to sleep, I need to power the monitor off then on to get it started. Not too much of a problem, I assumed it was the displayport hand shaking, as I have never used it before, only the HDMI. There may have been another way, but clearly the PC woke up OK, just unable to wake the monitor. (I only have one monitor connected).
 
mhh i have small whitish grayish dot in a upper right corner in a inside bezel its not dead pixel as when monitor is off it still there :confused:

Normally I'd probably chalk it up to inexperience in recent panels on my part, but I've just come from a Sony W Series 32" 1080p TV which I'd gotten because my PC usage shifted away from gaming and more toward watching movies and series/anime - obviously I was at a point where the sheer size of the pixels and having a 32 inch screen to game on when I'm sat about 50cm from it was getting too much.

Whilst the upgrade in resolution and PPI has certainly made all my games look nicer (without even mentioning the amazing transition from 60hz to 144 and g-sync), the banding is severely noticable almost everywhere, not just with sources where the banding would be present anyway.

On the plus side, there doesn't seem to be any backlight bleed at all, no dead or stuck pixels, no dust behind the panel, and I haven't notice any issues with pixel inversion despite failing that online test where the moving image is supposed to look identical to the stationary one. Dell's QC (or possibly just their manufacturing process) really is top notch.

On the down side, the banding really is pretty damn bad, and it only seems to worsen when using any of the custom .icm profiles that are around on overclock.net forums/tftcentral, and also worsens if I enable Flux at all.

I'd have sprung for an IPS panel, but even then I'd be looking at a lottery on the backlight bleed and dead pixels, reflection from the frames on some of them, and I'd be paying around 80% more than I paid for this one.

Seems even in 2016 you just can't get monitor perfection without drawbacks or risks lol

It's very interesting that you mention this as I find that the banding occurs the further away you move from the centre of the screen. Now that I think about it I don't recall ever seeing banding at the centre.

If this panel was 8 bit + dithering (Is that smoothing?) would the banding be less noticeable? Just load up CSGO and the splash screen that shows the CT at the start has banding also and that is slap bang in the center of the screen.

I'm going to take out my Asus VG278H and compare because it really is bugging me now.

I've tried 3DLUT with Reshade and it doesn't do much tbh with banding.
 
These panels do have some banding - tbh I've just accepted it as the price of a panel as responsive with high res and high refresh rates :S I only notice it though on the windows login screen and some gradients in the steam client so for me its easy to forget about.

EDIT: Or atleast with the settings I'm using on my Swift its rarely noticeable but I know it is there.
 
Here's an example of the banding without and with the 'night mode' function on my phone:

I haven't tried it myself but the debanding filters in Reshade apparently add extra information to the source material which can assist in limiting banding at source but I'd image it could cause unintended consequences/side effects in some circumstances. Its essentially modding the game itself to smooth out the banding at source, rather than addressing the problem of the panel. It might well work satisfactorily with some games but it seems a bit of an extreme measure as a long term solution.

Are you kidding, is this panel only 6 bit ?
I mean wtf, I been taking for granted that it was 8 bit like the now pretty old TN Rog Swift :eek:

If it only is 6 bit then we have the answer about the ugly banding I guess :(
 
Anyone with a S2716DG...

Do you get like a strobing effect, almost like a flicker, happen during loading screens of games and 3DMark?

I don't notice this effect whilst playing games or web browsing or watching stream, generally it happens on some loading screens.

It's odd, its certainly not stopping me enjoying the screen whilst gaming. Just wanted to know if its only me.

Might be becasue i can't run it at maximum refresh rate of 144Hz as my 2 x 670's in SLI only give me an option of 120Hz.

Disable G-SYNC and see if you still get it - seems to be a problem with G-SYNC (happens on them all) when the framerate drops to 0 momentarily i.e. in the middle of the game loading something - for some reason it seems to happen more on some driver revisions and not on others.

Happy now, was worried i had a fault with my monitor as getting flickering on loading screens for GTA V and 3D Mark, just disabled G-SYNC and it goes away.
 
ocd settings

Brightness 29
Contrast 75
Custom color: 97 Red, 99 Green, 96 Blue

nVidia Control Panel:

Brightness: 40%
Contrast: 37%
Gamma set to 0.78

Some people add more digital vibrance 53 to 55 % i left mine at 50.

edit missed a setting

Does anyone else find these settings a bit dark or is it just me?
