ViewSonic XG2431 Discussion Thread [Blur Busters Approved XG2431 - 24" 240Hz IPS with Best Strobing]

If you want to copy a max hz mode you need to lock the horizontal Khz in cru.

Don't get hung up on getting perfect refresh rate numbers like 60.000 just get it as close as possible so all your modes have the exact same scanrate as your native mode. then they are guaranteed to work.

Easiest way is to just copy and paste from your native mode in cru, lock the horizontal Khz by clicking the button and bump vertical totals up until you get it as close as possible to your desired refreshrate, I prefer a little bit over then under.

This method failed over a certain VT for me at least on my monitor. Another user was able to go higher than me in this thread though, so I can only assume tolerances are different between units or I just lost at the monitor lottery.

Questions to anyone who has received the monitor already: How are the colors on this display being that it is 6-bit + FRC? Is there any noticeable banding?

Thank you.

very strange those modes should be identical to using vrr at max hz at the same fps

You're telling me, I literally spent probably around 6 hours over 3 days trying to work it out and figure out why it wouldn't work. I'll post some screenshots later and see if anyone can see if i went wrong somewhere.

I've seen better consistency than that -- I've never seen same-firmware differences. This may be more GPU differences (AMD vs NVIDIA) as some drivers have bugs with certain VTs. Settings like HDR versus 8bit/10bit GPU versus other changes to the GPU signal has far more of an effect (e.g. older/newer GPU of various different brands) Also, if you have multimonitor, try single-monitor during VT tweaking before reconnecting your extra monitors.

Here are some ToastyX screenshots of the highest VTs I could set.

Thanks for the post with the screenshots!

You probably need a higher Overdrive Gain for 240 Hz than for 180 Hz. Try 1920 pixels/sec at www.testufo.com/crosstalk for easier OD Gain fine-tuning. I'll be adding adjustable TestUFO crosstalk animation speed in an upcoming version of Strobe Utility, since faster scrolling speeds makes it easier to fine-tune.

You're right, I do have a 3 monitor setup, so I disconnected the other two and tried again. Still the same results. I'm running the latest Nvidia drivers on a 3080 for more details. Not running HDR or freesync or anything.

I think it might be relevant to note that, turning on freesync on this monitor freezes my PC every single time. Not sure if that's a driver issue or an issue with the monitor itself though. I never use freesync so I didn't notice before. Gsync works fine on my older AOC monitor though.

I was feeling like the XG2431 was slightly laggy in 60hz mode, so I tested it against my AOC G2460 in 144hz mode.



XG2431 on left, G2460 on right.

I'm not sure if there's problems doing duplicate display with different refresh rates on 2 different monitors, but this is the result I got. Is this within normal range?

This was with hardware accel on in chrome and ultra low latency mode on, vsync off in Nvidia. I twice as much lag with hardware accel off in chrome and low latency mode on normal, vsync on app default.

What type of test is that?

[Chilicrunch]

It's from Lagom's LCD test page. I cloned the output of the two displays and took a photo. It's not gonna be very accurate, and it can only compare the lag between the monitors being tested, but it's enough to see that there's a decent amount of lag in 60hz mode for the XG2431. It's definitely less than the other monitors I have at 60hz though and I'm not concerned about it at all for anything other than fighting games.
