Hello,

i recently broke my g752 screen. I bought a replacement screen which i installed properly, screen is working just fine.

But I have a few questions about it if someone could help.

1 - my new screen is a generic one, so for 75 euros i assume it doesn't come with gsync right? Highest refresh rate i can choose in settings is 60hz.

2 - if you had to buy one lcd panel, which one would you choose ? is the original g752 an IPS one ? and is the difference between IPS and others noticeable ?

3 - i could go without gsync and ips......but there's another problem which makes me wonder if i am gonna send the panel back or not.....I explain :


since i installed it, the brightness constantly changes, goes bright when looking at a white screen (google for example), and dark when looking at a black screen (geforce experience).

I tried everything possible :

-disable adaptive brightness
-delete it from the registry
-no intel graphics in g752 so the solutions with intel control panel don't work
-there's no "automatic brightness" setting in windows (creators update 1709 i think)
-impossible to install splendid utility on this windows 10 build
-revert to asus official site nvidia drivers

none of this worked....does anybody have the same problem?

And, most important, is it a software or hardware issue ? Noticed it with the new screen, but what if (during two days without screen i plugged the pc on my tv) windows just updated itself and the screen is no responsible....?

Thank you for reading 'til the end, and sorry for my english, i'm french ^^

I would go with as high as you can within your budget. The G752 is one of the nicer screens. I would try and find a direct replacement if possible. Im not sure about gsync and where the hardware is for it when it comes to the screen. I would think it would be embedded somewhere? I know G-Sync goes with the display normally as all cards back to the GTX 650Ti support it.

I know my 75Hz G-Sync capable display in my G752 is a LG Phillips LP173WF4-SPF1. Although Im not sure which have G-Sync on ebay and which may not. I know some of the G752's did not have G-Sync.

Looks like they can be had for not much more then you paid for your current one?

In anycase, good luck! You're braver than me taking apart the lid and getting to the display. Cant be easy.

Thanks for your advices.

Mine is an "exactly the same at the beginning" SPF4
Don't know if I could mount an SPF1 on mine.

Anyone with a solution for the changing brightness thing ?

I think I found something.

On this french site reviewing an Acer gaming laptop, when it comes to the screen, they say this computer comes with a dynamic backlighting screen that is impossible to desactivate.

I think my new screen might be the same, and that nor windows, nor Nvidia is responsible for this.

I will investigate a bit more on that feature.....but which ****ty manufacturer implements a feature that you can't turn off.....it's a nonsense.....let people decide !

So for those like me who searched for weeks about adaptive brightness, messed with their regedit registry and more......ut's just your lcd panel....nothing you can do about it.
