G-Sync Dongle Stick

I was thinking, why don't Nvidia create a G-Sync Dongle Stick? We would just plug it to our monitor, and it'd work independently of the monitor itself. We wouldn't have to buy a new monitor just to use G-Sync, it certainly would be widely spread, and if we decided to buy a new monitor, there it is... working with G-Sync!

 

Instead of using a module inside the monitor, which changes its refresh rate to adequate to the video card, the dongle could send empty/freeze signals on the overflown refreshs and synchronize it with what the video card requires. 

 

 

If it's possible, I'm certain Nvidia would profit a lot from it. Both from gamers buying their cards just to use with it, and also from dongle itself.

 

 

 

What do you think?

Easier said than done, they would need to create another proprietary port on the monitor just to get that working, takes up space, less likely that a company would support it other than just changing out the scalar inside the monitor.

If it was that easy they probably would have done that instead

If the way I described was/is possible there wouldn't be the need for another port. It'd work on a regular DP, maybe HDMI. 

It wouldn't need to change the monitor refresh rate, as is done by G-Sync now. It would just kinda "filter" the incoming signals to synchronize with the video card rate, and then pass to the monitor.

 

Like for example, a game is being played at 35fps, G-Sync as it's now, will change the monitor to 35Hz to sync with the video card.

The way I describe, the G-Sync dongle would keep the monitor default 60Hz (therefore it wouldn't need a new port or a module inside the monitor). Then it would sync those 60Hz with the 35Hz the video card is sending with fake/freeze/repeated signals inbetween. So, in that case, it would be 35 refreshs with "new" content, and 25 refreshs inbetween with fake/froze/repeated content.

 

So a refresh cycle'd be something like this:

 

0 = new content sent from the video card

- = fake/freeze/blank/repeated signal

0 - 0 - 0 0 - 0 0 - 0 0 - 0 - - - - 0 - 0 - 0 - 0 0 - - 0 - 0 - 0 0 0 0 - 0 0 - 0 0 - 0 0 - 0 - 0 0 0 - 0 - 0 - 0 0 - 0 (60Hz, real 35Hz, repeated 25Hz)

If it was that easy they probably would have done that instead

 

I thought that also, but maybe they didn't have the idea or something. Worth trying

0 = new content sent via the video card

- = fake/freeze/blank/repeated signal

0 - 0 - 0 0 - 0 0 - 0 0 - 0 - - - - 0 - 0 - 0 - 0 0 - - 0 - 0 - 0 0 0 0 - 0 0 - 0 0 - 0 0 - 0 - 0 0 0 - 0 - 0 - 0 0 - 0

Small problem is it's the scalar that does that, not something before it.

You mean scaler?

Ja das, English is hard for me today.

I don't think it would have to do with it. The signal would arrive at the monitor just as a normal signal.

The dongle would just "transform" the 35fps to 60fps with some repeated frames.
