this g-sync, designed to eliminate tearing and reduce input lag.
wouldn't buying a 120hz 2ms monitor or more be the same?!
No, it would help slightly with tearing but it wouldn't come close to solving the problems that G-Sync solves.
This is a good, short explanation of what G-Sync is, what it aims to solve, and why no current technology can achieve the same effects.
also, the DIY kit is only for a single monitor. the g-sync monitors next year will only be compatible with new gen cards, and certain drivers.
couldn't they of adapted or widened the technology for people with flatscreen Tv's, other monitors etc. that would be awesome, and probably boost NVidia gpu sales!
Neither NVidia nor any other company could have made this backwards compatible with existing LCDs. The technology is so different from current standards and requires such extensive modification to the hardware that it is not reasonable to expect any end user to do. However, while I am looking forward to G-sync, I hope to see newer monitors coming with slots for these cards as opposed to integrated solutions so that you don't have to pay the up front cost for G-sync in your monitor if you don't plan to use it. This would also broaden the choices for people who want G-sync monitors.
I agree the single ASUS monitor restriction at launch is a downside, but at this point it seems like any traditional launch product, which requires close collaboration among all of the companies involved. Realistically there are not many revolutionary products that launch with broad market support, it takes time to build up the market.
to me its a good bit of innovation but a bit restricted.
I agree that it is restrictive. At the same time I would rather have a few validated solutions compared to a mass release with many combinations of incompatible or buggy hardware. You have to draw the line somewhere in order to make the project scope manageable.
The biggest challenge NVidia is going to have is to convince people what G-Sync is and why they should buy it. AMD has it easy as they can say "Mantle = More FPS," but it takes an entire article or a live demonstration to convince someone of the benefits of G-Sync.
