Copy 17.3" B173ZAN01.0 G-Sync certified EDID to 15.6" B156ZAN02.0 -> 15.6" true-4K G-Sync P650?

15.6" Clevos seem to offer the following panels for the 4K option:
- Samsung LTN156FL02-101: G-Sync; PenTile (RG/BW) not-true-4K; avg contrast
- Sharp LQ156D1JX01B/JW04: No G-Sync; true-4K; great contrast

Some 17.3" Clevos offer the AUO B173ZAN01.0, a true-4K panel with G-Sync certification.

The idea: Source an AUO B156ZAN02.0 (15.6", true 4K), clone the EDID from the B173ZAN01.0 to it, and install it in a Clevo P650 with G-Sync enabled. Voila, 15.6" true-4K G-Sync P650.

Any ideas on whether or not something like this would work?

 

My EE friend seemed to think it could work.

I'd love to see someone try it or an expert disprove it.

 

It would make the 15.6" g-sync certified and it'd run fine on the 17.3" edid (even their colour coordinates are fairly close). Unfortunately, it will not give you g-sync unless you also have a g-sync certified gpu and (v)bios.

Could buy the LTN156FL02-101 g-sync system and swap its panel with the edid-hacked Sharp. The pixel layout may be different from the Sharp, but wouldn't call the LTN pentile since those have a half-resolution screen (the rest being interpolated by the screen itself) and this Samsung has the normal 3840x2160 resolution, meaning that all its pixels are active. To be sure; if it were a 'true' pentile then this edid-hack trick would not work.

ps.
If you're going to do this mod, could you copy/paste the edid from the LTN? Have one copy, but not sure if it is the g-sync certified version.

 

There is no way to get g-sync enabled through EDID swap.

 

What's the technical reason?

 

money

 

That's what I'm referring to. Put this panel in a machine that is otherwise already setup for G-Sync.

The LTN156FL02-101 is PenTile (RG/BW), but to my understanding it takes in a standard signal and the panel itself downsamples it. I don't know enough to 100% say that's how it works though.

G-Sync already enabled on the machine, I'm just referring to 'hacking' a panel to spoof certification on it as well. Panel similar to one that is already G-Sync certified.

 

I just mean if you had the tools to stupidly do this, would it still not work? Like swap out the controllers too or something?

 

There is no technical but financial reason for NVIDIA to do this:
G-sync is a simple driver feature, so is SLI, Optimus or 3Dvision. BUT all of these features require a valid NVIDIA license code in firmware and doing the above will not generate a valid license and hence keep the driver from activation. G-sync license requires CPU family, motherboard model, GPU model & screen to match in order to activate.
Change one of them in and it breaks the chain and invalidates the license. External g-sync screens are a different story and will work just fine, but using an internal screen which has not been licensed and paid for in that specific combination will not work, no matter if it has been licensed on other models.

 

guess nvidia is a happy merchant eh?

 

Then it would work; reading out the edid is the only method for the driver to know what panel is present. Would be nice if the firmware-modded panel can run 75Hz or more with ease, of course.

That might be possible, too. It would be a terrible waste, though; that'd be asking the gpu to draw/compute pixels that will never be used. Might as well have sent the half-res image and double the framerate instead.

 

Yeah that's exactly what happens, I do believe. Which is part of why I think it's a particularly poor scenario that the only G-Sync '4K' 15.6" panel is a not-true-4K one.

 

Nvidia have not changed since the beginning in this respect so I am amused people seem surprised still.
