I'm all for 120hz+ though but not necessarily at the loss of image quality / odd monitor behavior.

Is the Qnix QX2710 Matt finish also the semi-gloss finish? Or are you talking about the full glossy version of the panel?

The "matte" version of the Qnix is semi-gloss. It's the best matte finish out of all the Korean panels however, in the end it's still a coating on the panel itself which could alter clarity.

Then try a lower overclock. I don't think 85hz affects the image at all if any. The extra 25hz still makes a pretty big difference.

You can also use madvr's smooth motion filter. It will keep the video framerate static but create 4 duplicate frames in between each real frame. This keeps the "cinema" look but still increases fluidity without causing the "soap opera" effect. The fact is that you are playing video that was filmed in 24fps and upconverting it to 120fps with smooth video project(SVP) it can look awkward or goofy. Using a frame duplicator can increase smoothness but keep the look and feel the movie was supposed to have. I have done a lot of testing with this and my rule of thumb is keep life action the same framerate with duplication(madvr) and ANY animation or CGI can be upconverted with SVP with not real negative awkward effects.

It may be my opinion but if you use SVP on live film it makes it look cartoony which is why i favor smooth motion. But if you use it on already animated video it doesn't bother too much.

Just some thoughts

Yeah even running at 72hz over 60hz looks a lot better thumb.gif

For now I decided to go with 60hz. I'm actually a little surprised that some people would go to a lower image quality panel and resolution like 1080p just to get 120hz. I think the difference with 1440p and a better panel is huge compared to the difference with a faster pixel rate.

On the movie issue - most movies are 24Hz/25Hz, so watching on a 60Hz causes tearing. Over many years our brains learn to completely filter out and ignore this tearing.

Now moe to 120Hz, which is an integer multiple of 24Hz and very nearly of 25Hz. This throws our brain out of sync as we don't expect it to be smooth. Given time though we will learn to appreciate it. Higher fps movies do look better but require a bit of getting used to.

As a side note: all 25Hz movies were originally shot at 24Hz, so you should use ReClock to fix that.

No, they use 3:2 pulldown which means the first frame gets displayed 3 times, the second frame two times, and so on until 24 frames are displayed 60 times. This is why you don't get tearing with 24FPS movies at 60Hz.

Unless the movies are shot at 120Hz, any smoothing by means of interpolation and not duplication (which happens already) is inaccurate and does not look very realistic.

Fantastic program, also fixes audio sampling rate to match the FPS change. Has exclusive audio modes (e.g. WASAPI).

Note: 25Hz (FPS) movies shot at 24Hz can lose around 5 minutes for a 2 hour movie, compared to 24FPS. That is a lot...ReClock FTW.

Note to those who are asking about whether overclocking a monitor is safe or not: Aside from the empirical evidence that it doesn't seem to cause any issues over time (years) other than the extra heat emitted by the controller chip, these single-input Korean monitors (all?) come with the EP269 controller, which is natively capable of a 450MHz pixel clock. How I see it, any pixel clock below 450MHz is considered an underclock tongue.gif meaning 60Hz is way below what the monitor can achieve at its native capabilities, which is ~106-110Hz generally for 450MHz (according to ToastyX).

This also makes sense why you should work at keeping the pixel clock at or below 450MHz. Spartan F8 has reported that doing so greatly reduces / eliminates the side effects of overclocking such as gamma shift (darkness), brightness uniformity issues (between the left and right parts of the screen), etc...

Getting my monitor soon, will report gamma and brightness uniformity with different pixel clocks using a Spyder4 colorimeter.

You know. I was thinking we need to do some EDID editing or spoofing or something to get these monitors recognized by the os that way we wont need another monitor to work on it when switching drivers or installing a new os. I'm starting to look into it, but this is also another important area. This getting a guide showing rolling of the tray to fix BLB. Cooling guide. Possible overvolting/volt mods(shouldnt need very much here). We also are going to need deeper understandings of Nvidia and ATI drivers. I am very experienced with Nvidia drivers and have figured out quite a bit about them. Like the fact this is the most important Nvidia Key in the whole registry.

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Video\{B202520C-37BC-47EC-91D3-AB0FF93DCA86}\0000

The GUID string is of course always variable just look for the one that has the 0000 0001 0002 0003 keys(the folder icons in the registry are called keys in the file tree) and go to the 0000 folder. To change the video modes the games can see edit the NV_Modes string trying to follow the examples of the other entries you can also edit this string when installing drivers by extracting the driver install package with winrar extract here in a new folder(label it so you can tell your different custom driver installs apart also when installing custom drivers which most of you already know you must DISABLE DRIVER SIGNING ENFORCEMENT VIA TESTMODE NFORCERS HQ APP or shutdown /r /o via cmdline or powershell then navigate to the advanced mode restart in the bcd blue menus http://www.eightforums.com/tutorials/4924-advanced-startup-settings-boot-windows-8-a.html). Then go to the Display Driver section nvdisp.inf and find the nv_modes string and edit the values there. You'lll notice the nvidia drivers are broken up into different sections section 01 etc etc at the very end of the nvdisp.inf you will see different driver designations which are Nvidias internal designations for the various cards.

Example from 326.80 x64 Drivers(always install main branch not opengl sidebranch)
NVIDIA_DEV.10D8 = "NVIDIA NVS 300"
NVIDIA_DEV.1180 = "NVIDIA GeForce GTX 680"
NVIDIA_DEV.1183 = "NVIDIA GeForce GTX 660 Ti"
NVIDIA_DEV.1184 = "NVIDIA GeForce GTX 770"
Just search your graphics card name. This gives us the designation for a 680 of NVIDIA_DEV.1180 and 770 of NVIDIA_DEV.1184 which are the same chip and the 770 on refrence design is supposed to have higher specd samsung ram instead of hynix which is probably more expensive. Now search these strings from the top of the file. Lets assume we are installing to Windows 8.1 on a GTX 770.

We get:
%NVIDIA_DEV.10D8% = Section020, PCI\VEN_10DE&DEV_10D8
%NVIDIA_DEV.1180% = Section091, PCI\VEN_10DE&DEV_1180
%NVIDIA_DEV.1183% = Section091, PCI\VEN_10DE&DEV_1183
%NVIDIA_DEV.1184% = Section091, PCI\VEN_10DE&DEV_1184
This tells us which sections the installer is going to jump to install the correct driver files(.dll files which are basically modular loadable exe files loaded by the kernel or other exes).

But make sure you get the correct section for your corresponding OS.
Which is determined with this string section
[Manufacturer]
%NVIDIA_A% = NVIDIA_SetA_Devices,NTamd64.6.0,NTamd64.6.1,NTamd64.6.2,NTamd64.6.3

Necessitating you choose the correct long list of
%NVIDIA_DEV.10D8% = Section020, PCI\VEN_10DE&DEV_10D8
%NVIDIA_DEV.1180% = Section091, PCI\VEN_10DE&DEV_1180
%NVIDIA_DEV.1183% = Section091, PCI\VEN_10DE&DEV_1183
%NVIDIA_DEV.1184% = Section091, PCI\VEN_10DE&DEV_1184

From the proper sections headered
[NVIDIA_SetA_Devices.NTamd64.6.0] = NT 6.0 = Vista or Server 2008
[NVIDIA_SetA_Devices.NTamd64.6.1]= NT 6.1 = Windows 7 or Server 2008 R2
[NVIDIA_SetA_Devices.NTamd64.6.2]= NT 6.2 = Windows 8 or Server 2012
[NVIDIA_SetA_Devices.NTamd64.6.3]= NT 6.3 = Windows 8.1
This is why if you got the latest Windows 8.1 RTM Build 6.3.9600.16384 Leak you'll notice the same microsoft internal build number.(I also read recently that a .1+ means a kernel revision meaning faster processing similar to a minor CPU upgrade)

This causes the installer to daisy chain through the various sections installing the proper drivers for your graphics cards. This is why newer cards experience performance boosts on their release more than older cards because those are the dlls actively being developed in order to feed more data umpf to get them to drive at thier full potential while older cards will see limited performance increases because your older card is still running on the same old driver they designed for it(with possible recompile but I doubt this is done all the time new recompile with optimized/more developed compiler over time means faster code). One time back when I had my old 8800gtx sli I installed gtx 680 only drivers after I modded the nvdisp.inf designation sections as I have illustrated above to be able to install on all cards and once I installed these 680 only drivers on my 8880gtx sli I noticed immediately that the graphics looked more bullish and seemed to have more polygons even on older games(it was rendering better/differently it was immediately noticeable). Really a GPU is just a processor. I find it hard to believe that Directx 11 cant be run on older cards it seems to me to be a matter of codebase and driver control carried out by Microsoft and Nvidia to force us to buy newer cards(maybe a limited amount of it is hardware support but I doubt all of it).

Ok following the daisy chain of driver installer subsections from our example assuming we are using a GTX 770 we see %NVIDIA_DEV.1184% = Section091, PCI\VEN_10DE&DEV_1184. Meaning we should proceed down the nvdisp.inf subsections to Section091.
[Section091]
AddReg = nv_DRS_addreg
AddReg = nv_FTS_addreg
AddReg = nv_commonBase_addreg__01
AddReg = nv_commonDisplayModes_addreg__02
AddReg = nv_controlPanel_addreg
AddReg = nv_global_addreg
AddReg = nv_miscBase_addreg__15
AddReg = nv_opengl_addreg
AddReg = nv_timingRestrictions_addreg
CopyFiles = nv_Drs_copyfiles
CopyFiles = nv_cplSetup_copyfiles
CopyFiles = nv_detoured32_copyfiles
CopyFiles = nv_detoured_copyfiles
CopyFiles = nv_license_copyfiles
CopyFiles = nv_nvsmi_copyfiles
CopyFiles = nv_opencl_copyfiles
CopyFiles = nv_sysDrivers_copyfiles
CopyFiles = nv_system32_copyfiles__06
CopyFiles = nv_syswow64_copyfiles__06
DelFiles = nv_nvsmi_delfiles
DelFiles = nv_sysDrivers_delfiles
DelFiles = nv_system32_delfiles
DelFiles = nv_system64_delfiles
DelReg = nv_clearRegistrySwitches_delreg
FeatureScore = DA
NVAllowIR3DDriverPreStage = 1
NVSupport3DVision = 1
NVSupportDisplayUpdate = 1
NVSupportGFExperienceExtendedOptions = 1
NVSupportPhysx = 1
RegisterDLLs = nv_common_registerdll__02

[Section091.CoInstallers]
AddReg = nv_commonCoinstaller_addreg
CopyFiles = nv_coinstaller_copyfiles

[Section091.GeneralConfigData]
MaximumDeviceMemoryConfiguration = 128
MaximumNumberOfDevices = 4

[Section091.Services]
AddService = nvlddmkm, 0x00000002, nv_nvlddmkm_serviceInstall

As you will notice there is the line AddReg = nv_commonBase_addreg__01 and nv_commonDisplayModes_addreg__02 in [Section091].
If you are modifying drivers for others to use or just as good practice for your own use you want to add tweaks to the [nv_commonBase_addreg__0n(1,2,3,etc)] Sections all of them(you could probably also use [nv_commonCoinstaller_addreg] in [Section091.CoInstallers]) so that they will be added no matter which GPU or Operating system the drivers are being installed on and of course [nv_commonDisplayModes_addreg__0n(1,2,3,etc)] will be where the NV_Modes strings are to be able to edit your display resolutions and color bit depth. So this is a little crash course in the layout of the newer Nvidia Drivers over the last few years so you can understand and navigate their fairly straightforward layout to get you started on your own modding and tweaking. Cheers.

P.S. I am impressed by Windows 8.1 RTM 9600 its so much more smooth and lag and glitch free makes gaming and just general os usage far more relaxing; at the same time I have a substantial reg file of tweaks and make extensive use of process lasso.
