Haha u bet. I survey viewsonic product for a long time and end up with acer duet to 144hz lol.

this vid must be made by one of you

Hi,to anybody who bought the kg240a. Could you post the picture of the box or manual that shows that the monitor is really the kg420a instead of the non A version.

Because in amd website, the kg240 support freesync up to 75hz while kg420a support up to 144hz.

I check idealtech and they listed kg420a around rm 899 and i found kg420 price the same at IT hypermart. My theory is that its actually the same product but i cant really differentiate whether its the A or non A version because the image on the box doest really indicate which version is it

Hi guys.I'm planning on buying one of these monitors this weekend.So from what i read KG240A is better than XB240H?Is it due to it having freesync?I don't have an AMD card though.

No, KG240A is not better than XB240H. It is not about it having freesync either.

Is it because KG240A is cheaper than XB240H by rm100?

Just tried my new Acer KG240(A). This is my first and only seen 144Hz, I have not tested or seen other model, only Youtube. It is the cheapest 144Hz monitor available for November 2016 at RRP RM899, or you can find it at about RM858 + delivery in Lazada, cheaper with RM30 or RM50 discount code. The next best freesync is AOC G2460PF @ around RM1150, with Nvidia Adaptive Sync too, which has a very good stand compare to flimsy Acer KG. In U.S. both Acer KG & AOC are in the same price (USD 199), but in Malaysia it's RM300++ apart. BenQ XL2411Z and Asus VG248QE are at around RM1250 but they're like 3 years old without Freesync etc.

"A" or "Non A"?
It is very confusing as some sticker (even the sticker behind monitor) says just KG240, no "A"; whereas only 1 sticker from the box says it's version "A". & Acer website only has 1 type of model, but AMD freesync website says there's 2 version (which it says non-A has freesync range of 40-75). So I guess there's only 1 model in Malaysia, it could be written as "A" or "non-A" version, but basically same model (I assume).

Lower limit Freesync range?
"Unknown to 144Hz" so far. Can't seem to find the lower limit of freesync in the web. Unfortunately I'm using 280X with Tahiti based so there is no Freesync supported, so I can't test the lower limit.

Brightness 250 cd/m² or 350 cd/m²?
The Acer site says 250 whereas the box says 350 cd/m². I cant measure without tools & I cant find any site has any review for this KG series yet.

Monitor stand
VERY FLIMSY. You can tilt forward/backward only. I'm not even sure if my panel is locked with the stand, if you're moving, make sure to grab the stand just in case it falls off. (Compare to next RM300 more expensive competitor AOC G2460PF, which allows you to tilt, updown, turn 360 to vertical and horizontal etc.)

Additional info
- All cables are provided (DP, HDMI, DVI, Power)
- I've problems when opened games, screen flicker (failed) in 144Hz mode, but worked in 120Hz. So I downloaded KG240 driver and update via Windows 10 test mode for unsigned driver. Game works, but I'm not even sure it is the driver installation that fixes the problem. Still need more time to explore. (Not sure if official, http://acer-us.com/6779_3_KG240/ or http://www.acer.com/ac/en/US/content/drivers)
- Black level adjustment is available for colour calibration
- Overdrive is available in "Off" "Normal" "Extreme"

thank your for insight on the KG240A.

btw is there any seller for acer XF240H in malaysia?

Don't think it is available in Malaysia.

Your next best bet should be AOC G2460PF @ about RM1185 including delivery to peninsula (http://www.lelong.com.my/aoc-24-led-monitor-g2460pf-hypetech-173232605-2017-01-Sale-P.htm) which have 144Hz Freesync, USB ports and much better stand.

I'm so torn between KG240A and G2460Pf. I don't know if the difference of RM340 worth it or not. G2460Pf looks like it does have better build quality and panel arggh so conflicted

Hi.
This is really a good thread.
I just upgraded my GPU from radeon HD 7870 to GTX 1060 and I am still a noob about this freesync and g-sync monitor. My current monitor is just a Philips IPS 60Hz. Looking fwd to upgrade my monitor to 144Hz. Since Freesync monitor is a lot cheaper than G-sync monitor, I would like to buy one. My question is can I enjoy the benefit of 144Hz Freesync monitor with my Nvidia gpu? Will there be any display issue? Please advise..

You can use a 144Hz Freesync monitor with your Nvidia GPU, but you cannot enable Freesync.

Ok.. I understand...Can I still enjoy frame rate of up to 144FPS? Will it cause image tearing or other issue.

Yes, the monitor will support up to 144Hz. Just enable V-Sync to eliminate screen tearing.

Thanks aim for AOC

I finally found Viewxonic XG240 sold in Malaysia. Slightly expensive than AOC g2460PF but people are saying this is the best 1080 144hz freesync monitor.

viewnet at lowyat is selling it too but at RM 1299

ya lowyat viewnet is selling xg2401, the price should be rm1299 but i think u can ask the sale person in there to give u some reduction on the price.

Side note, from the looks, my KG240A are identical to XB240H (no gsync) & the new XF240H (freesync) , so my guess is, KG240A (144hz freesync) is same as XF240H (144hz freesync) they're the same panel, just different stand.

Any ghosting at 144hz? Honestly I don't care about pivot, swivel or height adjustment that much as long as the panel works just fine. Might as well save RM 300 if the monitor is okay.
