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

[Chief Blur Buster]

To clarify is this at the 1920 pixel speed or thr 960 or whatever the stock one is ?

They look like 960 pixels/sec to me.

[teo]

indeed, those were 960/s. I edited that post to drop those attachments for now, but feel free to follow my attempts in the other thread. I added a quick try of 1920 and will try for more tomorrow.

I just got mine in today. Im newish to the website and cant figure out how to post photos/videos but as far as motion clarity without strobing, its pretty impressive. I have it on ultra fast response time and honestly haven’t noticed any sort of ghosting. It’s probably the cleanest image in motion that ive seen. And I’ve owned the alienware aw2521hf, Asus xg248q, asus vg258qm, BenQ xl2540-2540k, Benq xl2411, Viewsonic xg2530 and the xg2402. Most recently coming from the LG 27GP83B 1440p 165hz but I for some reason always end up back at 1080p 240hz lol

Good to hear! Mines on order, I will be comparing to the VG258QM soon.
What are you thoughts on the VG258QM vs the XG2431 ? Do you think I will have a new main ? haha

Definitely the XG2431. Picture quality is way better

[kyube]

Is the XG2431 overclockable? I'd love doing 250 fps VRR on it, 240 doesnt cut it ;/

strobe rate is necessarily hardware-linked to refresh rate for all fixed Hz modes from ~59 Hz to ~241 Hz

What about ~49hz to 58hz range?
There's plenty of old arcade games that were below 59hz like for example:
Mortal Kombat 54.706840hz
R-Type 55.017606hz
etc.

VRR strobing even in a limited capacity would be very useful for syncing with MAME emulation.
Like for example you mention Sonic the Hedgehog and 60hz strobing but the Sega Genesis/Mega Drive didn't run at 60hz it ran at exactly 59.92274 Hz(and 49.701459 Hz for PAL regions). Even a small fraction of a difference like that and you'll see some stutter immediately.

Due to flicker reasons, I could not convince ViewSonic to lower the strobe range any further.

However, I was able to convince other vendors such as Spectrum to support 48Hz and up strobing (Eve Spectrum Strobe Utility). Be noted that panel uses KSF phosphor though. However, it’s an excellent MAME panel for multiple reasons. Most people in this thread is looking for ViewSonic over Eve, but there you go — for MAME users, that’s another 60Hz strober that has an even-lower 50Hz strobe option — if 50Hz single strobe is important to you.

I will keep trying to convince manufacturers to permit a lower strobe Hz, at least via a hidden “Minimum Strobe Hz” adjustment setting, that can unlock all the way down to 48Hz.

For Advanced Users:
Undocumented 50 Hz Single Strobe PureXP Trick on ViewSonic XG2431 with RetroArch
That said, ViewSonic XG2431 can do 50Hz single strobe via RetroArch’s software based BFI at 150Hz in a fully “image retention proof” way. With the XG2431, you do need to use 150Hz + PureXP in order to get native-looking 50Hz single strobe with the best quality in RetroArch which now supports more than 2:1 black frame insertion multiples (100, 150, 200, 250, 300, 350Hz, etc for 50Hz emulation) for appropriate refresh-rate-capable monitors. For zero-crosstalk 50Hz on XG2431 with emulators, simultaneously combining hardware strobe and software blackk frames enables 50Hz PAL single strobing on XG2431. 50/150 and 60/180 three-frame black frame insertion is completely immune to image retention effects from software black frame insertion. For best effect, you ideally want 150Hz+QFT+PureXP+Strobe Utility+RetroArch BFI (3-frame BFI sequence via 2 blacked-out, 1 visible) will do the trick without any side effects of any kind except dimmer appearance. It is hackier than hardware 50Hz single strobe, but otherwise looks identical to hardware 50Hz single strobe — at least it can be done.

Understandable I suppose since global strobe is quite harsh to the eyes. I do wonder if using a higher MPRT value(like say 2ms or 3ms) at say below the 59hz range would lessen flicker to an acceptable level for Viewsonic.
That said VRR Strobing for 59hz and above would be great for syncing to a huge range of old arcade and console games so that the user doesn't have to set the refresh rates manually for every game and I suppose below that range you could double-strobe(or set it to a higher MPRT value).

There are arcade games that range from as low as 16hz to ones as high as 100hz or higher.
Popular games likes Midway's Rampage ran at an interlaced 512x480i at 60hz(which MAME reports as 30hz due to it being interlaced) so that's something to think about for the future but I suppose these edge cases are a long way off.
But bottom of the line there are literally thousands of arcade games that fall below 59hz.

If you don't mind 60Hz flicker for the best-in-class 60Hz motion blur reduction -- then XG2431 is currently the gold standard in "60Hz CRT emulating" direct-view LCD on the market at the moment at three-figure prices. I've never seen a desktop LCD mimick the motion clarity of a 60Hz CRT as well as the XG2431 can in this cost class.

Optional: For advanced users, if you want zero crosstalk at 60 Hz, you'll want to use the Vertical Total 4500 mode (Quick Frame Transport) for lower-latency strobing at 60 Hz with perfect zero duplicate images with zero strobe crosstalk top/center/bottom, in a crosstalkless LCD. The instructions are at the bottom of www.blurbusters.com/xg2431
If you do these tweaks, you can even eliminate the ultra-faint crosstalk to perfect zero strobe crosstalk. It does it even better than the old gold standards (XL2411's etc) and it can do massively bigger vertical totals too, which manages to fully zero-out strobe crosstalk double images at 60Hz even for top/bottom edge. The only other LCD I've seen do CRT motion clarity as well as XG2431 (after QFT mode tuning + Strobe Utility tuning) is the Oculus Quest 2 VR LCD and the Valve Index VR LCD. As you are already aware, a mandatory criteria of Blur Busters Approved 2.0 is retro-friendly motion blur reduction.

Are there Pursuit pictures of this 60hz mode?
and how about the 120hz mode? How does it compare to the XG270.. with high Vertical Totals?

Why arent there any comprehensive reviews or pursuit photos out yet? Are you please able to take/share some pursuit photos yourself, Chief?

...I'm still on the fence about buying this monitor.. because right now I'm setup with x3 XL2720z's and the AMA Low tweak on them is magnificent for 60hz single strobe and 120hz.

XG2431 was so tight in shipping quantities until recently, and ViewSonic held back review units. I will ask if they’re finally shipping review units. It’s their decision. These monitors use special chips (higher end scaler/TCON chips which are sometimes custom-fabbed) and chips are in severe shortages lately.

The same shortages affecting everything have been severely affecting these new upgraded 23.8” 240Hz IPS gaming monitor panels with apparently better quality than 25” IPS gaming monitor panels.

Are you please able to take/share some pursuit photos yourself, Chief?

I might, as a Special Blur Busters Approved edition, after shipping quantities become sufficient.

Also — Blur Busters isn’t a monitor reviewer (except for Special Editions such as GSYNC 101). We don’t want to compete against the users of Blur Busters testing inventions used by dozens of reviewers. See www.blurbusters.com/inventions

Strobe Utility tuned QFT modes on XG2431 significantly outperforms XG270 in strobing (which doesn’t support Strobe Utility), even 240Hz strobing is significantly better too.

Guys better be quick, Amazon US has some in stock! Not a third party seller, just ordered one. Was checking all day randomly, they had total of 4, still 3 left.

All gone, took less than 1 hour.
