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

[James Freeman]

Bumping the question, is there a 'hack' to strobe at 48Hz?

I used to have a XG2431 batch that can do <60Hz strobing. Although pulse width and other strobe utility settings were locked and pulse was too dim/short. It was probably a bug that they later fixed becase newer units can't do that anymore.

Ah, pity.
A good solution for film effect is to strobe at 72Hz or even 96Hz with BFI form the video player, but I can't find a good BFI solution for MPC-HC.

Try 96Hz + DesktopBFI running at REALTIME priority. This simulates 35mm effect pretty well, even without PureXP.

(Note: For those crazy low-Hz stuff, you could also concurrently enable PureXP with DesktopBFI, if you want low persistence 30-59Hz single strobe).

[James Freeman]

Thanks Chief.

Another question, is there a way to further lower the minimum brightness?
With Brightness at 0 I get 85 nit which is quite bright, my reference is 60 nit to which I set all my monitors.

I can reach 60 nit with strobing but sometimes I don't want that, or the PWM setting in the Service Menu but I can't save that.
It would be very convenient to have a non-strobing Brightness (PWM) option in the Strobe Utility that can go lower than 0.

Yes its very easy to lower the brightness as low as you want

go to the service menu power off monitor then hold down middle button and power button to turn on then press power button and change ISET value all the way down

This will make the screen as dim or bright as you want I have reached a max brightness of 1000 nits overclocked until the monitor powered off as self protection.

[James Freeman]

Thank you.

I thought ISET is only effective with strobing, apparently not only.
Also, CEC PWM is the regular brightness setting, on my monitor it goes from 23-81 which is equivalent to 0-100 in the menu.
All the settings jump back to default (but not the value) as soon as any DDC/CI command is sent form the Strobe Utility.

I don't understand why some manufacturers lock the minimum brightness to some arbitrary number, it is eye straining to work in a dim environment if the minimum brightness is still too bright.
Plus it makes it impossible to adjust the same minimum brightness with multiple monitor setup if the reference is lower on other monitors.

The XG2431 can obviously go lower than 80nit for minimum brightness as I see from the CEC PWM value in the service menu, but why ViewSonic locked the minimum to such high value?
My My Gigabyte M32Q at minimum brightness is at 60nit which is still a touch brighter than what I need in a dim room.
DELL U2723QE can go as low as 33nit at minimum brightness which is perfect for productivity in any environment.

If there is one thing that makes me angry is a great monitor with high minimum brightness.
A firmware update can easily fix that, especially if Chief pulls some strings at ViewSonic.

[James Freeman]

Sharing an idea.

I've noticed that the response time of the monitor at 60Hz is slower than at higher refresh rates, which is expected because the frame buffer at 60Hz is still 16.7ms.
An easy test with dual monitor configuration where you move a window up and down halfway between where the monitors meet, the 60Hz side is much slower.
A 60Hz Stobed mode has the motion clarity of a CRT and the lag of a buffered LCD at 60Hz.

What if we want strobed 60Hz with the faster response of higher refresh rates?

Solution:
Fraction Rate Strobing
A hardware half/third/quarter rate strobing that will effectively remove the need of QFT, BFI, or whatever hack we are doing now for a clear 60Hz (and lower) strobing image and have all the benefits of the higher Hz multiplies.

One can dream.

Update it's now 2 months using my XG2431 overclocked LED Voltage to 660 nits or 275 nit strobed.

ISET 157 and PWM 40

Monitor still works perfect, used it in heated room no AC and still works perfect and is COOLER produces LESS heat then when running it stock in HDR mode

I can conclude that once strobing is enabled becausethe backlight is being turned on and off 120 times a second it means it's still working LESS hard than being on constant in HDR hence less wear and tear on the hardware.

So 275 nit overclocked strobed is 100% safe, if anything had to happen it would have already happened this is totally safe therefore it means the engineer at viewsonic capped it at 200 nits because he was either lazy or an idiot.

The real question is if I should try 295 nits overclocked strobed with ISET 170, that might be pushing it but then the XG270 was 295 nit strobed from the factory

All in all I ordered a GLOSSY QD-OLED ultra wide 34" monitor AOC ARGOM from Amazon for a blackfriday price of only $600, I will replace this XG2431 because I can't stand this ugly hazy hideous dull nasty matte coating that this uses, those garbage Zowie monitors also have the same nasty matte coating.

Also games like GTFO and Warhammer 40K DarkTide looks WAY better on OLED without any nasty IPS glow.
Not to mention the absolute beauty of a Glossy Coating

[Discorz]

Very nice!

In that case I bet it can handle ISET 170 (300 nits at PWM 40, 750 nits pulse). Are u ready to take the chance?

Disclaimer: Do so at own risk;

I am enjoying reading thread even though due to liability reasons I can't make specific ISET recommendations (increased voltage-boosted strobing), just like Intel can't sanction uncapped overvolting of their CPUs -- power users enjoy pushing limits and crowdsourcing settings from each other -- but it's still risky.

I enjoy watching users hack their monitors; but I can't promise no damage. The risk is definitely there, and there is definitely certain setting combos that started to create significant overheat fault problems (e.g. pulsewidths and ISETs to maximum values).

Low temperatures are usually a good sign but can't guarantee a circuit doesn't fry or create accelerated LED wear and tear (e.g. reduced hours); be aware that there are risks other than heat too.

You can already sorta defacto do that by combining DesktopBFI and PureXP, or using software with software-based black frame insertion.

Basically using software BFI to black-out refresh cycles that you don't want to be strobed.
