ViewSonic XG2401 refresh rate paradox

[dreamer]

Hello everyone,

I just found a conflicting spec about XG2401.

http://www.viewsoniceurope.com/eu/produ ... php#pSpecs

You can see from the specs the frequency is 24-120hz. Isn't it supposed to be a 144hz monitor.

Is it overclocked or something? or just an amateur typo?

So it's just a typo then.

Still it's weird they made that type of mistake.

Is there a way to understand that if the panel is overclocked or not?

No it's not a typo.

144hz is *STILL* not a standard refresh rate, as far as timings go.

In normal frequency range and timings, refresh rates usually go up only to 123-128 hz.
Officially it's 123hz, which is why ToastyX Custom resolution utility will not allow you to enter a standard refresh rate higher than 123hz.

Whether anything higher than 123hz works depends purely on the monitor firmware.
Once you go past that (usually 129hz+), you need reduced blank (Lower vertical total).

So does that mean it's overclocked? I didn't see any other 144hz monitor having 120hz max freq. range in datasheets.

Also it says 24-144 here for example http://gaming.viewsonic.com/XG2401/ Why these specs are conflicting. Really weird.

It's typo. All 24" TN 144Hz monitors based on same lcd panel so it doesn't matter overclocked it or not.

Didn't know that. Which panel they use?

[Falkentyne]

I think he's referring to the AU Optronics M240HW01 I think.
Pretty much every 1080p 144hz TN uses this. Even the LG 24GM77 was proven to use this.
