..unless I just happen to find a Sony GDM-FW900 at a flea market or something. 😆😁
Don't even bother finding a good FW900. They are made on the much older platform than 2070SB, F520 and other top of the line 4x3 crts and die way quicker because of a range of problems: tube, flyback, etc.
Not even mentioning that it tooks 20-30 minutes to warm up from a cold start and lower peak brightness. It's just a one big headache compared to a last gen 4x3 crts.
I've had 2 faulty ones and sincerely regret every meter I carryed those monsters LOL

How do you hook up these 2070SB / FW900 etc monitors to video cards that only have displayport?

Hi just got the monitor and just wanted to ask something. I can't seem to access the BIOS. XG2431 will show [No Display] until windows login. I had to use another monitor to show BIOS. Is this something that I can fix?

This can affect some motherboard with some displays -- try turn on/off FreeSync in the monitor's OSD. It will swap to a different set of EDIDs, one of which should show the BIOS.

If this fails, open a ticket with ViewSonic support (and share with me) so I can reach out to the XG2431 dev team. Thanks!

Hello, Chief. Сan u tell me, does this monitor support 240Hz strobbing? That is, will I have 240Hz with strobbing on, or will the frequency be lower? Sorry for my English.

240hz strobing is supported but will have higher crosstalk.

I’m curious, what is the approximate brightness of this monitor at various strobe widths for 60hz? Is this posted anywhere?

What would the 60hz MPRT/strobe duration be at around 100 nits?

Yes. This monitor supports strobing from ~59 Hz through 240 Hz in essentially 0.001 Hz increments. You can strobe at any custom Hz you want!

There is a continuous continuum of strobe quality from lowest Hz to highest Hz.

Still far lower than many other IPS monitors -- it's the best 240 Hz strobed IPS I've seen so far.

It is a continuous continuum of slightly improving strobe (by a fraction of a percent) crosstalk for every Hz you get below max Hz, until the crosstalk pretty much nearly zeros out (at ~120Hz QFT / large VT and below), it can be tuned to be barely visible at 144 Hz, but many don't mind 180Hz-240Hz strobe -- it depends on your personal threshold for seeing crosstalk especially at the top/bottom edges.

The center perfect crosstalk-free zone becomes taller and taller the more Hz you go below max Hz, which is due to a law of physics effect in the ratio of refreshtime:GtGtime ... Basically the refresh cycle time versus the pixel response time. ALL panels in humankind have worse crosstalk at max Hz. That's why NVIDIA locks ULMB below max Hz, but all Blur Busters Approved monitors always unlocks the strobe max Hz, so you choose to strobe lower Hz at lower crosstalk, or max Hz with more crosstalk.

Supported pulse widths is 1% to 40% of a refresh cycle, so you can guesstimate it as percentages of max-brightness. However, there is a light amount (safe) of voltage boosting, so it will be slightly brighter than that minimum baseline -- probably exceeding approximately 200 nits at Light thanks to the voltage boosted strobes. (just like the XG270 does too). The sweet spot pulse width is usually either Normal or Extreme for most people, when using Large Vertical Totals at 60 Hz, which is capable of going darn near-zero-crosstalk during 25-30% pulse width.

PureXP default pulse width settings:

Light = 40% of refresh cycle
Normal = 30% of refresh cycle
Extreme = 20% of refresh cycle
Ultra = 10% of refresh cycle
Custom = Tunable 1% to 40% via ViewSonic Strobe Utility.

MPRTs will match pulse width, so pulse width 20 means MPRT(100%) will be 20/100ths of a refresh cycle, by the pure Blur Busters Law mathematics, excluding backlight decay effects (capacitors, fast backlight phosphor, etc) which adds approximately ~0.1ms. For most pulse widths, that is an insignificant error margin, and MPRT(100%) of a good strobe backlight pretty much exactly matches pulse width in milliseconds.

I will let reviewers test the actual brightness -- feel free to vote at RTINGS Suggest-a-Monitor for the XG2431 to be reviewed.

I've sent a ticket with ViewSonic support and I have yet to receive a reply. So I've tried using an HDMI cable to plug my monitor, BIOS seems to post when using an HDMI. With a displayport cable, I can't get a BIOS post. is there a reason for this?
