G-Sync support for laptop display ?

[Mohamed_45]

I wan't to know how G-Sync work with laptop display, as i'm planning to buy a replacement screen for my laptop's poor display, my laptop has GTX1070 but doesn't support G-Sync , i found a display on Ebay that fits my laptop and supports G-Sync (B156HAN04.2), will my laptop support G-Sync if i installed this model. ?

Your 1070 *doesn't* support G-Sync? That seems a bit odd. Having said that, if your GPU does not support it, swapping in a display that does won't matter. Both pieces of gear need to support the standard to make it work.

All 1070's, mobile or otherwise, support Gsync. The Panel in the laptop didn't. If you swap to a gsync panel, you should be good to go.

So if i changed the display to a G-Sync compatible screen would my machine support G-Sync or is it a module thing that should be available in the laptop to support G-Sync , i'm asking because i haven't found anything on the net to explain G-Sync work ?
How do you change a panel ?
How do you know if the panel supports G-Sync or not ?

 

[SkyBill40]

G-Sync is tied to the GPU and the display as it's a hardware thing. Both need to have the technology to make them work as designed. As for changing the panel, that's something I don't have any experience in doing. The only way to know if the panel supports it or not is to verify the model and documentation for it.

The laptop itself didn't support G-Sync , came with a standard panel, could G-sync work if i installed a G-Sync compatible panel ?

That would be accurate.

MERGED QUESTION
Question from Mohamed_45 : "G-Sync on laptops.. ?"

Does the laptop with G-Sync comes with a special G-Sync module to run the display or only the display has this module or compatible G-Sync screen can work without a special module.. i'm asking because i was looking to change my display on my Laptop to a better one that is G-Sync compatible ..
Please i need a professional answer ..

You asked this question in a previous thread and it was already answered: In order for G-Sync to work, both the GPU and display have to carry the technology. You can't have one without the other and expect it to work. What laptop do you have, specifically, and what screen are you looking to put into place? Don't leave anything out if you want an answer seeing you left the other thread hanging and which was was started on 20 JUL 18.:

Finally, here is the answer you're after and the website from where it was taken:

"Another major difference is the proprietary nature of G-Sync, which requires a special Nvidia chip to be installed in the monitor or laptop."

I have the TRACER II from CyberPowerPC with a 1070

After looking it over, changing the screen out won't likely be sufficient as the mobo in the laptop likely doesn't have the required Nvidia G-Sync chip to make that work. That being said, there's more than enough horsepower in that 1070 to run anything being played on that machine at high frame rates with details turned all the way up.

So, in essence, you've got a nice laptop... but one that doesn't support G-Sync. Enjoy it for what it is or sell it and buy something else. Best of luck either way.

Acc this, the mobile cards use a software gsync solution. There does not appear to be separate hardware necessary on the mobo side ,other than possibly a cable change:

so i checked Nvidia forums .. and the Display should be connected directly to the GPU in order for G-Sync to work.. no special module is required for laptops.. then again i don't know how to tell if your Display is connected directly to the GPU ?

 

[SkyBill40]

If that's accurate, why then would the website I supplied which involves laptops not say so? Are you saying they're not accurate? Go ahead and buy that display and if you try and install it only to find it still doesn't work as you expect or that you can't return it... it'll be on you. The Ars article says nothing about Cyberpower laptops. Take note of that.

You've been advised and warned accordingly. Good luck.

It's true the G-Sync requires a special modules for Desktops external displays only.. laptops however don't need a special module only the Display should be connected to the GPU directly with eDP not through the iGPU ..which what i'm asking now if anyone knows how to tell if you have a direct connection to the Display with the GPU instead of the routed through iGPU

Another important thing to consider is seeing that laptop displays are not necessarily meant to be changed or swapped out, there is a chance that the replacement you're considering buying may not be on that laptop manufacturer's "white list" for compatibility. So, as before, there is a substantial risk in buying a different display and not having it work as desired.

If you want a guaranteed G-Sync laptop... buy a better one from the start.
