Re: does gsync use bandwidth?

Adaptive-sync uses zero additional bandwidth after the monitor sends its initial EDID/DisplayID table, relying on a timer in the GPU to know when a new frame can/must be sent. G-sync sends trace amounts of data polling the display every time a new frame is ready. More bandwidth is lost just keeping ...

Re: nVidia Interview - Why G-Sync Is Superior to FreeSync

I believe the point he's trying to make is that the amount of overdrive needed is dependent on the refresh rate, hence the G-Sync module keeping previous frames in memory and adjusting overdrive calculations on a per-frame basis. Every G-Sync monitor will have this capability but most FreeSync moni...

Re: nVidia Interview - Why G-Sync Is Superior to FreeSync

The interview does bring up the interesting point about the increased ghosting in the Adaptive-sync panels, but it does a very bad job discussing the underlying reasoning IMO. I was under the impression that ghosting is mostly a product of back-end T-CON behavior, which has little to nothing to do w...

Re: Monitor firmware upgrade to support Adaptive Sync

I think that these adaptive-sync options generally require a frame buffer in the monitor, to allow regular updates to the LCD when the PC isn't sending them often though. Some monitors might not have a full frame buffer, or at least one with full storage (e.g. RTC) only a few lines of buffer. The R...

Re: G Sync is only DRM

While I appreciate a lot of the technical innovation Nvidia has done, my regard on the net benefit to consumers differs a bit from yours. IMO, their walled garden style of feature releases substantially hurt the adoption of stereoscopic displays and physics engines in the cases of 3DVision and PhysX...

Re: G Sync is only DRM

Because VESA Adaptive-sync is just a protocol and not a defined hardware implementation, the only thing on your list DP 1.2a/1.3+AS scalers couldn't do in theory is the partial screen updating. Any AS scaler with a full frame buffer could advertise 0 Hz minimum input and do self-refresh, as well as ...

Re: G Sync is only DRM

So it looks like in the mobile space at least Nvidia is willing to brand a setup indistinguishable from Adaptive-sync (plus whatever GPU/driver side logic needed) as being G-sync. The open question is then which way they choose going forward on the desktop. Continue using proprietary monitor FPGA mo...

Re: G Sync is only DRM

I would be very carefull with this driver if this is indeed true then nvidia will get a bad name. If this is not true however it might be a very good opportunity to install some nasty malware on your system. It seems too good to be true to me. Maybe I am a bit paranoid however about this but its st...

Re: G Sync is only DRM

Does this make it more likely that we'll see combo G-Sync/Freesync screens, because they're probably similar internally? Or less likely, because simultaneous support for Freesync would violate Nvidia's terms? It means that somebody proved nothing stops Nvidia GPUs from using vanilla Adaptive-sync p...

Re: Any signs of 4k+ 16:10 Monitors coming?

I hope not. Just because im getting really sick of these 16:10 nostalgians QQing in EVERY forum. what? 3840x2160 isnt enough for you? It's because 16:10/4:3 resolutions are typically just taller-with-equal-width versions of 16:9 instead of 16:9 being wider versions of 16:10/4:3. (See: 1920x1200/192...
