LG 27GK750F-B - 240Hz, 27" 1ms Blur reduction, Freesync

[mushi]

mine is still ok since I've applied the fix on the first post on the first day I got the screen.

here's my attempt to record video with my phone the testufo, using the tips chief said on the post (focus on the text above, and then pan manually):

looks good i have a cynical eye too. i'm a happy user
do you experts notice anything wrong?

Hi, I wanted to ask if the results are good, once with G-Sync and once with LG MBR. my monitor is the lg 27gk750b-f

Hey,

Great photos! Did you use stationary camera (OK for strobe crosstalk, if exposure is limited to exactly one refresh cycle) or pursuit camera (best for universal display motion blur photography).

For more accurate strobe crosstalk photography, please use www.testufo.com/ghosting and follow the handwave smartphone instructions. The sync track makes it easier to tell whether you pursuited correctly or not.

Hey,

I used a 960fps camera to get these photos. I've tested a few monitors before, but the lg 27gk750b-f is just amazing with the MBR function.
I currently have the ViewSonic xg270 and the Asus VG279QM
and i will send them back and stay with my old gk750 because it is simply the best ( Watch first 2 photos)

and sorry for my bad english guys

May I ask if there's a point overclock the vertical total if I'm using freesync? Does it make a difference?

AFAIK, you'll get marginally lower display lag near the center of your screen.

Thanks! For some reason when I OC my display with CRU it doesn't detect as an freesync display. So I'll probably not ocing for now =)

Overclocked vertical total is useful for strobe crosstalk reductions and/or latency reductions.

That said, decision whether to overclock the vertical total OR overclock the refresh rate, depends on panel capabilities. For example, max-unoverclocked-Hz with overclocked Vertical Total, sometimes means the monitor can handle an overclocked Hz with a reduced vertical total.

Monitors does not always work this way especially if they use TCONs that scan-converts (see this Quick Frame Transport related post where some panels refresh at a different scanout velocity than the cable), and monitors can sometimes pop up an unwanted symbollic "OUT OF RANGE" during Hz overclocking even if the panel theoretically works overclocked just fine.

Thank you very much Chief! I'll try to OC again later, just need to find why it just doesn't detect Freesync on the AMD Driver. I just love all the knowledge and kindness that people on this community have to help! Happy Holidays!

so I followed the advice in this thread to set up a custom res with CRU to eliminate the stutter issue with ULMB. The issue is that I play games at 1728x1080 stretched (16:10, used to play 1680x1050 but made a custom res for this) and with stretched res I'm getting the stutter issue. Can anyone give advice on how to set up my custom res to eliminate the stutter? Obviously using the same pixel timings for 1920x1080 doesn't work for the smaller res.

Some ULMB monitors have incompatibility with monitor scaling with ULMB. Use GPU scaling instead with ULMB.
