OLED and gsync

I have in mind to buy a 4k oled, I was oriented on the panasonic (lz980) but I would like to understand if they have gsync or not (having nvidia as gpu) and if it is a necessary thing for the tv to have it (I know panasonic generally have only amd freesync and vrr), among other things I read that sony and panasonic do not put gsync in their tv, but vrr, so what are the differences between vrr and gsync?
 
I have an LG C2 OLED 4k 65inch and it comes with Gysnc/VRR. It's definitely good to have especially when the display is 120hz. VRR is basically just the HDMI standard version of Gsync/Freesync, they function basically the same. It's very easy to setup a TV with VRR in the Nvidia control panel, you basically just toggle it on and it will be recognized as a Gsync compatible display.
 
Gsync implies another chip on the screen to handle synchronisation between the screen and the graphics card. VRR/Freesync do the same thing within the HDMI/DisplayPort standard.
 
Been pretty impressed so far with my C2. We have an old C9 back in the bedroom that we hardly use. Has some dead pixels around the edges which apparently is a common problem with aged units. Hoping this C2 doesn't develop that problem because I'd like to get at least 3 and more like 4-5 years out of this TV.
 
I was reading about OLED fringing text issues, how Microsoft doesn't want to fix cleartype because the issue will "go away" at higher resolutions, etc.

I also happened to read about nvidia's DSR tech, which allows you to render at a higher resolution and scale it down. I don't have an OLED monitor (WoLED or otherwise) to test on.

I did this on my monitor and it's interesting. Was curious if the combination gives good results without cleartype enabled. Anyone want to try it out?


Cleartype: off
Nvidia control panel: Manage 3d settings
DSR Factor: 2.25x (also 1.78x, 1.5 and 1.2)
DSR Smoothness: 28% (17% to 100% I've tried)
Change Resolution: Dynamic Super resolution

or for less dots, more smoothness seems to help.

Cleartype: off
Nvidia control panel: Manage 3d settings
DSR Factor: 1.78x
DSR Smoothness: 65%
Change Resolution: Dynamic Super resolution
​

So, the nvidia control panel font is blurry and small, because it isn't dpi aware and scales, but everything else is looking great. Basically a cheat to get greyscale font smoothing. Anyone else confirm? Does the same hold true with WoLED and other OLED displays? (debating an HDR monitor, and the text rendering is giving me pause.)

DSR factor... the higher it goes the smaller the nvidia control panel app text gets and blurrier. browser, notepad, desktop, etc, all get crisper at the same apparent size. Smoothness of 65 seems to eliminate some wierd artifacts with the non-scaling text.

So, no one wants to do the experiment to let us know if it solves fringing issues/looks ok-to-good on an OLED? Shouldn't take more than a couple of minutes then you can change it back. :)
 
I don't connect my 55 inch OLED to my computer anymore as I don't like playing games on controller (don't have a setup w/ desk, tv, k+m).
