Dell S2716DG 1440 144 Hz G-Sync Owners Thread - Page 173

post #1721 of 4833
Ok so I'm planning to get this monitor here in South Africa. Only 1 shop has this but it's MUCH MUCH cheaper than the rog swift pg278q and even the pg279q is a lot more expensive than the pg278q so this is about the cheapest 1440p g-sync monitor out there. I'm planning on upgrading from a Qnix qx2710 @ 110hz PLS panel. On 110hz the qnix do get a bit dark but not notices anything that bothers me so much except the usual screen tear or stutter and G-sync will solve this for me. I have a 980 ti 4790k @ 4.6ghz and 16GB 2400mhz ram so it's high end gaming pc. I'm just scared I'm buying something and should rather wait for a monitor with most common issues like vertical lines, Pixel Inversion, etc resolved. But are these issues really that bad or just minor. I guess it's luck of the draw with monitors these days unless you get professional monitors but then you suffer g-sync and higher refresh rate.

I just got mine this morning. First impressions (I used it for a 5 minutes and left for work) was pretty crappy colors. Even coming from an existing TN panel.. I have the BenQ XL2430T. I'll have to adjust that when I get home.

Questions for anyone that are playing CS:GO competitively (I mean that lightly... like ESEA, CEVO, etc, I'm not a pro nor intend to be one). Coming from the XL2430T @ 144Hz and fps_max 300, what do I want to adjust here? I have 2 980s in SLI (I had them running individually before) and a 5960X @ 4.6GHz. I would expect no frame drops .. and constant 300fps with my old setup. Even with my old setup I'd drop to 280-290 before.

After turning G-Sync on it wasn't natural. Again, this was a 5 minute impression. The colors were bad as I already stated. But there seemed to be frame drops. When I'd hit escape to go to the game menu there would be a freeze/delay. I'm not sure that's normal.

Anyone with this monitor that plays CS:GO - how do you feel about it?

I did a 3-step process:
  1. use X-Rite's ColorMunki Display to get 6500K with 100cd
  2. use X-Rite's ColorMunki Display to get 6500K with native
  3. spend hours and hours in dispcalGUI, low calibration speed, 6500K, gamma 2.2 with around 2k samples

For ColorMunki's software there was a need to use softMCCS to read back what exact settings it set since MCCS is bugged on this monitor and will reset it to factory defaults on reboot. So after it finished 1. and 2. I had to do simple maths to actually get what to set in the OSD.

Gamma is really wrong by default. Either use nV control panel to correct it or get a calibration device wink.gif

I'd try disabling SLI, running G-SYNC with VSync OFF and fps_max at 140 or even 120 for example. Basically experiment, it's a complex issue with many variables.



You can take a look at this article. It's quite old, I'm not sure whether it's fixed in newest CS:GO or the drivers.

I calibrated it 3 times with 2 programs, first two were to get the optimal OSD settings like brightness and RGB and the final one was to get the final ICM profile (with ReShade LUT generated from it).

I ran your profile and settings through displaycal:

Current calibration response:
20:19:45,427 Black level = 0.1238 cd/m^2
20:19:45,427 50% level = 20.84 cd/m^2
20:19:45,427 White level = 92.88 cd/m^2
20:19:45,427 Aprox. gamma = 2.16
20:19:45,428 Contrast ratio = 750:1
20:19:45,428 White chromaticity coordinates 0.3058, 0.3189
20:19:45,428 White Correlated Color Temperature = 7006K, DE 2K to locus = 2.4
20:19:45,430 White Correlated Daylight Temperature = 7011K, DE 2K to locus = 2.5
20:19:45,430 White Visual Color Temperature = 6901K, DE 2K to locus = 2.3
20:19:45,430 White Visual Daylight Temperature = 7124K, DE 2K to locus = 2.4


It's just that your CR beats TFT centrals and they use a £2k spectrometer and my results were near enough the same as theirs. I understand that each panel is different but look at the white temp, it's way off.

Very interesting read. Going to try GSYNC + fps_max 143 when I get home to see if it feels any better.

Silly question maybe, but why 143 vs 144 vs 145? When I do fps_max 145, it sticks at 143. It all seems odd, I would expect the behavior to be locked in at 144... somewhere smile.gif

Also for calibration device, http://www.amazon.com/Datacolor-S5P100-Spyder5PRO/dp/B00UBSL31Q/ref=sr_1_2?ie=UTF8&qid=1453838816&sr=8-2&keywords=monitor+calibration would work?

I have no explanation other than methodology and software used. They use LaCie Blue Eye Pro which I do not know, but isn't it quite dated?

Setting the engine FPS limit below G-SYNC's maximal value with VSync being off allows for the minimal input lag while keeping G-SYNC working all the time. When FPS goes over G-SYNC limit then VSync dictates what happens: when it's on then the driver actually limits FPS just like classical VSync does which can lead to input lag. When it's off then G-SYNC stops working and FPS is not capped - just like classical VSync off setting.

A good engine self-limiting will always be better than forcing it through the driver.

Keep in mind that nVidia actually recommends G-SYNC on with VSync on. I found that it depends on the game and requires experimentation. Just check what works best wink.gif

For the calibration device I'd advise reading Argyll CMS' documentation which has a list of supported hardware. This open-source colour management system is used by dispcalGUI which I found to be more powerful than X-Rite's default software. I chose X-Rite ColorMunki Display since it has the same hardware as the more expensive version, it's just slower at measurement and seems to be the best bang for the buck.
