Red led indicating Gsync ? whats that all about ?

When you go into the X34 OSD settings, under the one with the wrench symbol (I think, I'm not at home right now) are the settings for the LED below the front bezel. You can select its color, and you can also change its mode to "MNT". I have NO idea what MNT technically stands for but when you select this mode, the light will be white when g-sync is not active and then will turn whatever color you select (in my case, red) when g-sync IS active.

So when you are first booting up your computer, the LED will be white until you get into the Windows desktop then it turns red (or whatever color you select). And when you load up a game, the LED will go back to white for a few seconds while the game is loading up and then turn red again generally when you get into the games full screen title menu.

Its just a way to visually confirm that g-sync is active (at least, according to the monitor anyway).

Sorry you are correct, my mistake.

I am not sure if the issues we're seeing with the X34 are panel related or perhaps more likely due to the fact it's a 60Hz native panel that has been overclocked to within an inch of its life. This can't always be a good thing.

Right so I had a quick look once again into the horizontal scan line issue.

Prior to updating my drivers I noticed scan line issues in the pendulum test. I also had it noticable when I played fishing planet.

After installing the latest nvidia drivers that were released yesterday, I still notice the lines in the pendulum test, however, I cant detect them at all in fishing planet anymore.

Now i couldnt give two ****s if the pendulum test does that as long as my gaming doesnt.

Can you guys share your findings after updating the drivers too thanks

Well I'm not sure how I feel about this. I have nearly a perfect monitor. I can not produce any known issues. Back light bleed is almost none existent. No crazy lines that I have seen. But I can only do 95Hz

I'd keep it. See my earlier post about what kind of graphics hardware you need to push 80+ FPS in far cry 4 and Arma 3.....

I have 2 x Titan Xs + a 5960x, all highly over clocked and under a custom water loop and the instant I start setting every in game graphic option to its max setting, I only get 70-80 FPS in Far Cry 4 and you don't even want to guess what I get in Arma 3 when you start pushing up that view distance slider smile.gif

This is exciting news if driver updates are resolving the problem. We need more people (@drfish, you play fishing planet too) to confirm this to ensure it's not a one-off.

I knew that Nvidia was not just doing variable refresh rate but also doing some algorithms in the background to vary the pixel response too. And I suspected that this algorithm (not being tuned to widescreen or some other reason) was messing with the X34 and producing the scan lines. I assumed that the dynamic pixel response was coded in the G-sync firmware but if it is also in the drivers, it could explain how your game doesn't show the lines anymore.

(This is all speculation.)

EDIT: Wait, you said you installed the latest drivers. Did you remember to turn on G-sync in the NVCP after installation before going into the game? Just making sure

As far as I know, every monitor maker has to send their panel to Nvidia for G-sync certification before they allow it to be sold as a G-sync monitor. (source: one of the PCper videos with Tom Peterson).
So, I think they must have taken this panel through its paces for overclocking to 100Hz with G-sync. But just like Overclocking a CPU varies from unit to unit, despite their testing on a few panels, not all units coming out of the assembly line will be equally overclockable. In the case of these monitors, I don't know what is limiting the max refresh. G-sync electronics, panel properties, or DP bandwidth limitations?

Keep it. You could never tell the difference in a blind test.

OK, been doing some testing. Using the NVIDIA pendulum test, there are some faint horizontal lines that start from about 30% from the right edge of the display, slowly grow in "strength" to about 50% heading left, and then from 50% to the left end about the same "intensity" while using G_Sync. 30% and to the right edge is devoid of the lines.

So far, no monitor settings have had any affect. Appears completely related to the G_Sync module. For some reason, the grey color of the hills in the back of the pendulum test make it most apparent.

I have to figure out why in Windows 10 with G-Sync on, it's almost non existent. Seems to also be game dependent. I don't know if it's because of the games individual color palette. In some games its virtually impossible to see, in others a bit more easy.

It is faint enough that I have to lean in and get my eyes about 8 inches away to see it in the pendulum test as really "noticeable". If I sit back in my normal 24"-30" viewing distance, I have to look real hard to notice it. In most games and in Windows 10 it is completely unnoticeable.

Refresh rate also does not affect it. Look's identical at 60 Hz as it does at 100 Hz. Simply a function of turning G-Sync on and off. So far seeing how faint it is; it's not a deal breaker. It's kinda one of those "you only see it if you really look for it" deals. I will hook up my TN Swift tomorrow to see how that compares. I am curious though as to why these faint horizontal lines exist and why they are only on part of the screen. (They are too faint to take a picture of.)

More to come tomorrow..

Do any owner can film what you actully see while playing/watching movie so we can see the impact of the blb/ips glow (not shdowplay or internal software) thank you
