Testing Nvidia G-Sync on LG FreeSync Monitors! | The Tech Chap

What is G-Sync, Freesync, V-Sync and HDMI VRR?. Parsing

All PC-Gamers of the planet Earth, and console players, too, unites one problem-vertical ruptures of the image. And there seems to be a bunch of technologies that solve this problem:

Let’s look at the technologies of adaptive synchronization of the image today and for all today and for all.

For those who do not know. And what is the actual problem?

In order for the image to appear on the screen, at least two things must happen:

Conventional monitors operate at a frequency of 60 Hz, that is, they are able to withdraw 60 frames per second, and playing is 144 Hz and above.

But the graphic processor lives in a completely different world. In the games, everything is constantly changing: the foliage is swaying, the stream murmures, the enemies jump out of the corner. Each frame differs in its complexity, so a different amount of time takes a miscalculation.

In other words, the monitor has a constant frequency, and the video card has a variable.

So it turns out that for one cycle of updating the monitor, the video card can prepare more than one frame or less.

Because of this, not only that the smoothness of the picture suffers, the artifacts also appear in the form of vertical image ruptures. By the way, when watching films, such artifacts can also appear, because the movie is shot in 24 k/s.

Possible problems with Freesync on Nvidia

I have a pitch on RTX3070. I want to take the MSI Optix Mag301CR monitor. Main points: 200 HC and Freesync (there is no G-Sync Compatible in the list). I understand correctly that tears (tearing) will have it if the FPS will be more than 200, and in the case of it there will be less than 200? What will I have options for getting rid of gaps? V-Sync is likely and obvious the worst solution. How good it is to expect Freesync’a workout in the role of G-Sync? It seems that if the monitor is not in the “G-Sync Compatible” list, then Freesync can give out artifacts of the image and generally works in a narrower range of the duke than the monitor (not 1-200, for example 1-90), which is also not good, because This situation will not reveal the full potential of iron. What remains in this case? FASTSYNC? But as far as I know, he adds an input lag. Is it so? What are the problems at FastSync’e?

Yes, everything will work fine, you will include GSINK in the Nvidia panel and Frisink will work

Right. And the lower threshold has long won (see. LFC) on Mag301CR Freesync operates in the range of 48-200 Hz via DisplayPort or 48-180 via HDMI. But if the FPS drops below the treasured 48 frames, it will double / triple to get into the Frisinki range. Frisink problems are very rare. Personally, my YouTube in full.screen mode works with gaps, if hardware acceleration is included in chrome, but otherwise there were no complaints.

Damn, what kind of lfs? I also encountered rare failures below the lower threshold and it was uncomfortable.

Low Framerate Compensation Actually the same doubling of the FPS when falling below the threshold. Since most monitors are the lower threshold for frisinka. 48 FPS, the monitor must maintain a frequency of 96 Gz so that LFC works. Here look for your monitor: https: // www.AMD.COM/RU/Products/Freesync-monitors

Ah, that’s what it is. I have a monitor when a fps decreases to 60 and lower Gertzovka. It turns out at 70 FPS. 70 hertz, at 60 FPS. 120 hertz.

By the way, yes, it included on Monica the function of output frequency and tested, when the FPS in the games fell below 50, the frequency was doubled and it was 100

It seems like if the monitor is not on the “G-Sync Compatible” list. and generally works in a narrower range of the duke than the monitor gives out (not 1-200, but for example 1-90)

As I understand. this is even if G-Sync Compatible is a sticker. will be present. But not really. Upper border. There will be the upper boundary of the capabilities of the monitor (144, 200, but at least 100500), but the lower. on the position of conditional 48 fps (and if fps falls below. then the technology is turned off).

And in the entire range (from 1 to the ceiling of the monitor). These technologies work only on G-Sync (present, with a module) NVIDIA or on Freesync Radeon.

P.S. But I can be very wrong if not right. Correct.

Upper border. There will be the upper boundary of the capabilities of the monitor (144, 200, but at least 100500), but the lower. on the position of conditional 48 fps (and if fps falls below. then the technology is turned off).

The lower border in the same way depends on the possibility of a particular monitor, and this threshold is directly registered in the characteristics.

Freesync panels with NVIDIA G-Sync turned ON

Forget these frisinki and gsinka, I have 2070Super and 240Hz Monika, there are more than 240Hz and much less, there will be no tears and other shit on the normal gland.

From an important for himself, he allocated. Connect the Display Port Monica Cable, I remember with HDMI I had some indirect jokes.

HDMI has a heap of versions there and you need exactly the one that can give out 240Hz at your resolution, and the monitor and on Vidyakha.

From personal experience. Also RTX 3070 and LG 32GK850F monitor with Freesync (NVIDIA is also not certified). In theory, you will have two technology settings. Basic and expanded. On an expanded one from 48 Hz to your monitor declared by the monitor. But my problem was such that if the FPS falls below approximately 50-55 the monitor begins to flicker like a strobe, especially if there is a blue sky in the frame and t.D. Now I am sitting on the base mode there from 60 Hz to nominal like. No problem. But I will tell you so if all this is turned off, you almost never see if you have a 120 frame in the game, and even more so 200 like Herz, then you will not notice that with Freesync, what’s with fastsync, what without it- or sync. And yes, you were correctly prompted for you correctly that connect by DisplayPort if there is an opportunity, for example, on my monitor if you connect via HDMI instead of 144 Herz will be only 120. P.S. By and large, at a high hertzovka and personnel frequency, this is all the fins. But if you have a synchronization and you want to have no gaps when the personnel frequency jumps from, say 45 to 90 fps and there was no delay in the input then these technologies will help.

You should not score. It is worth figure out a little. I will try to more briefly explain what I myself managed to find out (feel). Different monitors can behave differently (not all of them are certified by NVIDIA). FPS range matters, especially if it is lowered in the shorter way. As a result, we have the use of the lower border in 30 FPS, and the upper. The Device of Your Monica. If the FPS will get used to the kind of renewal of your Monica. Frisink no longer works. So for the best effect, it is advisable to lap the FPS just below your duke so that the FPS does not fly higher (for example, 198 at 200 Devil Monica). If you observe these conditions. In most cases, you get a smooth picture (without breaks). Unfortunately, Frisink is not always possible to work with different games, but in most cases this may already be factors that may disappear after the first renewal of the driver. It is better to play in full screen mode if possible. In general, good luck to you, I hope you made basic settings in the driver, and you can enjoy a smooth picture for a long time.

Oh yes, I forgot to say. People correctly advise. Connect all this business through the display port. Otherwise, you will not even see a Frisinka activation item even in the NVIDIA settings. And in general, the port of the port has a good bandwidth. If you directly briefly describe the algorithm of desirable actions to briefly. Frisink’s ON MOCHIK, ON it in the NVIDIA panel (put a box where there is a full.screen mode, as well as there is a galk from below), turn off a vertical in your games, play those games that you want with a smooth picture (in full screen mode with Lock FPS Your Hertzovka (preferably even a little lower, on the PUR FPS)).

Alternative methods for turning on the G-Sync or Freesync monitor

If the above settings are not available or G-Sync does not work on Windows 10, then in the NVIDIA control panel, follow the following actions:

1) Expand the branch “Settings 3D” 2) click on 3D3 settings) click the global settings tab

4) Select the parameter “Monitor Technology” 5) Use the opening menu and select the parameter compatible with G-Sync.6) Press the application button.

In addition, you may need to click the “change” section in the “display” section and apply a higher renewal frequency or other resolution so that G-Sync start working.

After you take these steps, G-Sync should start working on your Freesync monitor.

Why is G-Sync does not work and how to enable it

  • First you need to update the NVIDIA drivers to the video card to the latest version (at least 418.91!). Specialist. utilities to help;
  • Next, pay attention to the monitor connection integration. DisplayPort is required (1.2a!). Approx.: this chip will not work through HDMI;
  • The video card should be NVIDIA of the 10XX or 20XX series (Windows 10);
  • In the monitor settings, it is necessary to enable Freesync (t.e. Put this parameter into the “ON” / “included” mode).

AOC / As an example monitor settings

In most cases, after the tasks of such parameters-G-Sync will turn on automatically (with a parlor. compatibility of the monitor and default settings of the drivers). NVIDIA and AMD on sites, by the way, have their own lists of “proven” and compatible monitors.

If the G-Sync does not “turn on”, it is necessary to manually change a number of parameters in the video card settings.

To do this, press the right mouse button in any free place of the desktop. in the menu that appears, select the “NVIDIA control panel” item.

Next, you need to find and open the G-Sync Adjustment menu (in English. “Set Up G-Sync”). In this tab, turn on G-Sync!

Turn on G-Sync (NVIDIA control panel)

After you need to go to the “3D Parameters Management” tab, and in the “global parameters” in the line “Vertical synchrome-impulse” set “G-Sync”. Cm. An example below.

Note: Instead of masonry “Vertical synchroimpulse” you may have another tab “Monitor Technology”-if you have it, you also need to set “G-Sync”.

Actually, after such “manipulations” G-Sync should start working. And the quality of the picture will become an order of magnitude better (no more breaks).

Close to the topic!

Vertical synchronization (Vsync) in games: what is it and why is it necessary, how to turn it on / disable it.

What to do with V-Sync if I have G-Sync? Leave on or disable it?

This is the most common dilemma of owners of monitors with G-Sync. It is customary to think that this technology completely replaces the classic V-Sync, which can be completely disconnected in the NVIDIA control panel or simply ignored.

First you need to understand the difference between them. The task of both functions is theoretically the same. overcoming the effect of the screen rupture. But the method of action is significantly different.

V-Sync synchronizes personnel, adjusting them to a constant frequency of monitor update. Therefore, the function acts as an intermediary, capturing the picture and, accordingly, display of the frame, so in order to adapt them to a constant frequency of frames, thereby prevent the image breakdown. As a result, this can lead to Input Lag (delay), because the V-Sync must first “capture and streamline” the image, and only then bring it to the screen.

G-Sync works exactly the opposite. It adjusts not the image, but the frequency of the monitor update to the number of personnel displayed on the screen. Everything is done hardware using the G-Sync module built into the monitor, so there is no additional delay in displaying the picture, as is the case in the case of vertical synchronization. This is its main advantage.

The whole problem is that G-Sync works is good only when the FPS is in the supported frequency range of the update. This range captures frequencies from 30 Hz to the value as the monitor supports as much as possible (60Hz or 144Hz). That is, this technology works in full range, when the FPS does not fall below 30 and does not exceed 60 or 144 frames per second, depending on the maximum support for the update frequency. It looks very good, given below infographics created by the Blurbusters service.

What will happen if the frame rate per second goes beyond this range? G-Sync will not be able to configure the screen update, so that it doesn’t work outside the range. You will find exactly the same problems as on an ordinary monitor without G-Sync and classical vertical synchronization will work. If it is turned off, then the screen ruptures occur. If it is turned on, you will not see the gap effect, but an IPUT LAG will appear (delay).

Therefore, in your interests to remain in the G-Sync update range, which is at least 30 Hz and the maximum of how much the monitor supports (most often 144 Hz, but there are 60 Hz displays). How to do it? Using the appropriate parameters of vertical synchronization, as well as through limiting the maximum number of FPS.

What, therefore, out of this conclusion? In a situation where the number of personnel per second falls below 30 FPS, you still need to leave the on vertical synchronization on. These are rare cases, but if it comes to them, then the V-Sync guarantees that the effect of the rupture of the picture will not arise. If the upper limit is exceeded, then everything is simple here-you need to limit the maximum number of personnel per second, so as not to approach the upper boundary, at the intersection of which V-Sync is turned on, thereby ensuring the continuous work of G-Sync.

sync, freesync, monitor

Therefore, if you have a monitor of 144 Hz, you need to enable FPS limit at 142 so as not to approach the upper limit. If the monitor 60 Hz. set the limit 58. Even if the computer is able to make more FPS, then it will not do it. Then the V-Sync will not turn on and only G-Sync will be active.

Requirements for the use of technology

Without further continuation, you can say briefly: support is not available for absolutely all connections between GeForce video cards and Freesync displays. This is not necessarily due to the intentions of NVIDIA to use only its own products. Just the AMD dynamic update function has its own requirements, which should be fulfilled. Therefore, you need to check that the video card maintains the relevant standards, so the display is connected to it through the corresponding cable.

See also  How To Connect The Camera To The Monitor

For the correct operation of the technology, you are required:

  • Video cards of the Pascal series (GTX 1000) and above.
  • Freesync monitor (not every model is compatible, especially on weak units, problems can arise).
  • DisplayPort 1 cable connection.2A (no HDMI support).
  • GeForce Game Ready drivers not lower than version 417.71.

The fact that the function can only be activated on the maps of the Pascal (GTX 1000), Turing (RTX 2000) and more new ones can be disappointed. For comparison, G-Sync even works on the GeForce GTX 600.

Why does Freesync require video adapters of the new series? This is due to the fact that the connection is required using DisplayPort 1.2A, this means that this standard supports the Pascal series and newer.

The connection also depends on the quality of the monitor. Officially, NVIDIA tested 400 models with this technology, but certified only 12 of them in quality and compatibility. But this does not mean that only these 12 certified models are suitable for use. you can turn on the function on absolutely all Freesync monitors connected to DisplayPort 1 cable.2A. And in most cases, it will work. This shows how high the company puts the bar regarding the requirements for the quality of models for their certification.

VRR and Freesync compatibility with G-Sync

On CES 2019, NVIDIA introduced the new G-Sync implementation-now the monitor synchronization will be provided by Variety Refresh Rate (VRR, present in HDMI 2.1) and video cards NVIDIA GTX 10 generations or NVIDIA RTX 20 generations. This technology requires a monitor with Freesync.

Of the 400 proven monitors with Freesync 12, the G-Sync G-Sync will definitely work from 400 proven monitors with Freesync 12 will definitely operate at full power G-Sync

This significantly expands the list of suitable monitors, and also gives a chance that any monitor will be able to work with G-Sync.

With the development of synchronization technologies, it is worth waiting for more and more new methods that combine quality and accessibility. Perhaps very soon the owner of a very budget computer will be able to play without any interference.

List of monitors certified by NVIDIA to launch G-Sync on Freesync

On the day of writing management (January 18, 2019.) NVIDIA certified only twelve Freesync monitors, on which you can run the G-Sync solution. The list is ridiculously short, but, fortunately, these are not all the models that include the solution of green. On the Web, thanks to the Reddit user under the Cryptoel pseudonym, the Google document has appeared, to which a special form allows anyone to add a monitor model that managed to launch G-Sync. Below you will find an official list of certified monitors:

AMD Freesync vs Nvidia G-Sync

The competitor of the AMD-NVIDIA company, and it is called G-Sync, has a dynamic change in the frequency of the screen update. The principle of work by Freesync and G-Sync is largely similar, but AMD has synchronization control is entrusted to a video processor, and NVIDIA has a monitor in which a special controller is built-in. This determines the advantages and disadvantages of both technologies.

So, due to which Freesync wins the G-Sync and vice versa:

  • Monitors and Freesync do not require the installation of an expensive controller, which means that both for the manufacturer and the buyer are cheaper. The price of devices “sharpened” under AMD is less than 80-100.
  • For the use of Freesync technology, unlike G-Sync, equipment manufacturers do not pay licensed deductions, so its ecosystem covers an increasing number of various devices. Today these are not only monitors for PC, but also laptops and TVs.
  • Freesync supports the display update in the range of 30-240 Hz, and G-Sync is only 30-144 Hz. For modern games, this difference is not too relevant, but AMD has a decent tank for the future.
  • G-Sync is compatible with a much larger number of video cards models, including obsolete, such as GTX 650 Ti.

So what is better: Freesync or G-Sync? The use of both technologies gives a picture of approximately the same quality, so it will not work to call one a clear leader, and the second lagging behind, alas, it will not work. The graphics in the game depends on many factors and to a greater extent. on the characteristics, performance, combination of iron, also on the properties of the game itself. Graphics improvement technologies only reveal the potential laid down in devices. If you like NVIDIA products more, then G-Sync is better for you, if AMD is Freesync. Both that and the other is definitely not bad, so the best assistant in choosing is your personal taste.
