So here is what I found out from Nvidia's website as my source for some answers because there are questions you guys haven't asked.
Eventually for "Select
' monitors and various resolutions.
Q: What are the resolutions of G-SYNC monitors?
A: NVIDIA G-SYNC enabled monitors will be available in a variety of resolutions from 1920x1080, to 2560x1440 to 4Kx2K. The ASUS VG248QE NVIDIA G-SYNC enabled monitor has a max resolution of 1920x1080.
Q: What display companies are planning on introducing G-SYNC monitors?
A: Many of the industry’s leading monitor manufacturers have already included G-SYNC in their product roadmaps for 2014. Among the first planning to roll out the technology are ASUS, BenQ, Phillips and ViewSonic.
It's safe to say you can tack on $100 - $175 to current
monitor prices in addition to their current cost when they come enabled. Example ASUS PB278Q cost about $600 now on sale, when they come out with a G-Sync version expect to pay $700 - $775 usd. Kit only works on ASUS VG248QE and not your existing monitor.
Q: How much more does G-SYNC add to the cost of a monitor?
A: The NVIDIA G-SYNC Do-it-yourself kit will cost approximately $175.
The G-Sync Kit is only for specific monitor ASUS VG248QE and not other existing ones = you have to buy a new G-sync monitor.
Q: When will I be able to purchase this?
A: The NVIDIA G-SYNC Do-it-yourself kits for the ASUS VG248QE monitor will be available for purchase later this year. We will have more information to come on how and when to get G-SYNC enabled monitors in the future.
Doesn't work for all games.
Q: Does NVIDIA G-SYNC work for all games?
A: NVIDIA G-SYNC works with all games. However, we have found some games that do not behave well and for those games we recommend that users take advantage of our control panel’s ability to disable G-SYNC per game. Games that NVIDIA discovers that have trouble with G-SYNC will be disabled by default in our driver.
The limitations: Not for the Korean monitors.
You cannot over clock a 60 Hz monitor that is multi-input with scalers, which is every monitor except some of the Korean monitors like QNIX at 2560 x 1440 resolution. Any over clock on the list of on-board companies that offer 60 Hz 2560 x1 440 monitors WILL frame skip. No over clocking capability.
So you'll have to make the choice to either go 1080p for 120 Hz - 144 hz or when ever they finally come out with 1440p for 60 Hz refresh rate G-sync enabled and no in between alternatives.
I wouldn't mind buying a new 2560 x 1440 resolution monitor I guess
because I already play on one at 60 Hz but how many people will be inclined to buy a new monitor just for G-sync?
How long will we have to wait for 2560 x 1440 monitors to hit the stores?
Personally I'm not going back to 1080p monitor and if you aren't when can we expect 1440p to be supported? What time frame before these become available?Here's the SOURCE of FAQ's
