Upgrade ASUS VG248QE with G-SYNC Kit

First published October 21st, 2013

gsync-logoGood news:
The ASUS VG248QE monitor is G-SYNC upradeable!

Don’t know what G-SYNC is?
G-SYNC eliminates tearing, eliminates stutters and reduces input lag.
See GSYNC Preview Part One: Fluidity and Part Two: Input Lag.

DIY Upgrade Instructions:
1. You need an ASUS VG248QE monitor.
2. Purchase a G-SYNC DIY Upgrade Kit from NVIDIA.
3. Follow the Installation Guide (pdf) and the Video (YouTube) to install the upgrade.

NVIDIA says:
“For a limited time, we are making a G-SYNC Do-It-Yourself Kit available. If you have an ASUS VG248QE monitor, you can purchase the kit and mod your monitor. Assuming you are proficient with moding, this solution might be right for you. The installation process should take approximately 30 minutes.”

If you prefer G-SYNC to be already included, see List of G-SYNC Monitors.
Several monitors with G-SYNC built-in, are coming before the end of 2014.

    @Chief Blur Buster –
    Do you think that the G-Sync module will be a generic one? Ie, One size fits all so to speak. I ask as I am wondering if it can be fitted to an Asus VG278H/HE monitor as well?

    Also does the Benq XL2720T share the same panel as the Asus VG’s mentioned above? If so would the DIY upgrade then be applicable to the Benq? I know these questions may be a bit premature, but your experience/knowledge/opinions & expertise would be appreciated. As I am planning to upgrade my rig around Lightboost/G-Sync enabled screens.

    Thanks in advance. ;O)

    hey i’ve got a question mark, tbh am thinking of getting the asus VG248QE but my question is will there be any decrease in performance compared with Q1 incoming asus monitors since these would be g synic ready, even if a little nvidia hasn’t said any thing about this so am just wondering i think its important to know

    Any way to get into some kind of mailing list… would love to be one of the first suckers to do this XD also ill pics of the process

    another question. my end goal is to customize the horrible asus vg crosshairs, any chance you know of any tools t hat can access the firmware/hud elements,. or if there is a jtag/spi pinput is accesible?

    any info/input is apreciated. thanks

    • We’re not aware of JTAG tools to hack monitor firmware at this time, however, we’re aware that Display Corner in Switzerland did successfully reverse-engineer some elements of the LightBoost hardware:

      …Our disclaimer: (to keep manufacturers happy; they read our blog nowadays!). Bear in mind hacking monitors in this manner can be risky — there’s a high chance of bricking a monitor, and manufacturers aren’t happy if bricked monitors are returned for warranty claims.
      …Our support: But that doesn’t mean we’re not enthusiac at watching the user community do amazing things. Being 120Hz monitor news, we still report on interesting/exciting developments of end users doing interesting modifications on 120Hz monitors. Keep us tuned!

    Hi everyone, thanks for this website, i’ve just ordered an asus VG248QE and i would like to apply the DIY kit soon but i have a question:
    – am i able to use the Lightboost backlight strobing for 2d gaming if i do the modification? (i have a 3d emitter so it’s supposed to work right?)

    You say the exe to enable lightboost in 2d will not work with the g-sync modification, but i should not need it as i have the emitter that’s right?


    • tigerman says:

      Ok i’ve read som more articles, no lightboost anymore with g-sync, there is now the ULMB, but it cannot be used togheter with g-Sync as i was supposing, it’s technically much more difficult to be able to use both togheter due to the variable monitor refresh caused by g-sync.
      Same apply then for 3dvision, as the emitter actually needs a fixed framerate to send the signal correctly to the glasses.
      As i am both a lightboost and 3dvision user (and i dont’ care too much about colors) i feel that this g-sync upgrade doesn’t worth much for me.
      My opinion will change completely once they add the ability to use both g-sync and ULMB simultaneously.

    Do these add on boards include the ULMB technology? I have this monitor and am considering adding this board.

    • Yes, the GSYNC upgrade adds ULMB to your monitor.

      It is better than LightBoost in that there’s no color tinting (no more pink/purple tint), you can adjust the picture colors via the monitor (using a 3rd party utility), and you can run at more refresh rates (85Hz, 100Hz, and 120Hz).
