Blur Busters Forums

Hi everyone.

I have a BenQ XL2420Z monitor that came with firmware V2 installed. On this version, my HDMI port doesn’t work.
After doing some research, I found out this was a common issue with that firmware version.

I’ve been trying to find a link to download firmware V4, but all the links I’ve come across (including the ones on this forum and the Blurbusters page) are no longer working — which makes sense, given the age of this monitor.

Could some kind soul please help me out and share the V4 firmware for the XL2420Z?

Big thanks in advance!

Here's V4 for XL2420Z.

I'll add a mega link as well. This includes firmwares for other Benq monitors: XL2720Z, XL2411Z, XL2420Z, XL2430T.
