ViewSonic VA2455sm 24-Inch
- Edited
Hi --,
- Yes it is a true 8 bit
- Our Flicker free tech nearly eliminates the flicker at all brightness levels with the LED backlighting
Regards
Hello,
I'm considering purchasing the ViewSonic VA2455sm and I need to verify two things:
- SuperClear Pro technology provides true 8-bit color performance
Because it uses 8-bit, that means there is no dithering (FRC) occurring correct?
6-bit often using FRC dithering to simulate 8-bit.
- Flicker-Free
Is there any brightness range that would cause PWM to occur? Or is it PWM-free through the entire range (0-100)?
Thank you!
Slacor But I also remember using the my old tube monitor and never dealing with any of this.
CRT's never used dithering and some of them had very high refresh rates. I had a CRT long ago that could do more than 120hz and it never gave me problems even after this issue started nearly 5 years ago.
It was an Viewsonic Optiquest V95 and cost more than $3000 over 15 years ago and could do nearly 2k resolution.
After using this monitor for about half a week, I have to say this is much better then my Dell U2414H.
It's semi-old tech (DVI and VGA only!) and has some ghosting, but I'm becoming nearly symptom free which is phenomenal.
We'll see how it progresses.
Slacor Thanks for the update. I can't find any for sale on eBay or elsewhere. Mind if I ask where you purchased it and if there are any more available? Considering trying it.

I got it here
There was a refurbished one I got very cheaply (making it easier to trial).
There's a "newer model" that is flicker free but doesn't specify whether 8 bit or 6 bit.
If you want to try the new one, I would suggest contacting them and asking them.
I'm using this monitor along with a nvidia card on linux, all of which has allowed me eliminated the usage of dithering. So it was not this monitor alone that "made everything better" is regards to dithering.

Slacor Appreciate it. I just ordered a BenQ 8 bit / Flicker free panel suggested by JTL. If I don't have any luck I'm bookmarking this ViewSonic and will give it a run. When using a monitor such as this in combination with an Nvidia GPU, is there any setting that needs to be changed in the Nvidia control panel, or should as-is be fine?
ThackeryBinks There's some discussion of that here
Slacor Thanks again. Just read that whole page. If I'm not mistaken, Windows + Nvidia + PWM free 8 Bit monitor shouldn't require any setting changes in the registry or Nvidia control panel, right? Unless we're to use the dithering.exe file in conjunction with the above formula?
ThackeryBinks The dithering exe for for Intel cards. And regardless I have ideas of something "more permanent" than an EXE for Intel Cards to control dithering/PWM
ThackeryBinks we have a first report that a new NVIDIA card seems to be worse than an older one: https://ledstrain.org/d/124-gtx-1070/9

So the new model Slacor was talking about uses 6bit+FRC. Will attach email and datasheet later.
Hi JTL,
I grab this from the data sheet - Colors 16.7M (6bit + Hi-FRC)
I have attached it
Let me know if you have any questions.

Hello
I'm just wondering if the ViewSonic VA2465smh uses a 6-bit or 8-bit color depth, and if it uses dithering/FRC technology for 8-bit.
Thanks
