I have had a response from Hazro regarding the banding issues:
"Dear Customer,
This notification is intended for Hazro customers affected
by any of the problems outlined below. If any of the issues do not affect your monitor, please discard this message and announcement.
----------------------------------------------------------
ISSUES:
----------------------------------------------------------
- Banding on gradient backgrounds and images.
- Random pixelation i.e. 'sparking' of pixels.
----------------------------------------------------------
CAUSES:
----------------------------------------------------------
- Banding is caused due to improper configuration of the
scaler engine used on the AD Board Controller.
- Sparking of pixels is caused due to interference between
I/O connector board and main controller board.
----------------------------------------------------------
RESOLUTIONS:
----------------------------------------------------------
- Hazro have developed a firmware fix which reconfigures the
scalers gradation values at set resolutions. Hazro are
looking into 'packaging' the firmware to allow customers to
carry out the fix themselves [i.e. in the form of a software
upgrade].
- Further shielding of the harness cable linking the I/O
connector board and the Controller board totally eliminates
all sparking issues.
----------------------------------------------------------
ACTIONS AND TIMELINE:
----------------------------------------------------------
HZ24Wi [24" MONITORS ONLY]:
- Should a software 'self installable' firmware upgrade not
be possible, the product will warrant an RMA where Hazro
engineers will upgrade each monitor individually. Hazro will
inform all customers of the outcome of this [i.e. whether it can be done by Hazro or the user] on or by:
THURSDAY 11th SEPTEMBER
- The product is to be returned to Hazro for RMA. Shielding
requires the monitor to be opened and only Hazro engineers
are permitted to do so.
HZ26Wi [26" MONITORS ONLY]:
As above; however, the firmware will be ready one week AFTER the completion of the firmware fix for the 24" HZ24Wi. If the firmware is not user installable i.e. we are unable to 'package' the firmware into a .exe or .dmg file, the same RMA process applies as stated above.
* If a customer has reported BOTH of the above issues on the SAME monitor, the monitor must be returned for RMA only AFTER:
THURSDAY 11th SEPTEMBER
----------------------------------------------------------
CONDITIONS:
----------------------------------------------------------
The above issues affect only a handful of monitors. Hazro
will strictly enforce the Warranty Policy which can be found
in all instruction manuals and also on-line at:
http://www.hazro.co.uk/downloads/Hazro_Manual_v3.pdf
Please refer to the 'Miscellaneous Issues' section and point
3 in particular."
