I have two Acer XG270HU monitors, and I loved them, until I discovered that AMD Graphics Overdrive disabled Freesync, among other Freesync issues. Well that wasn't the problem, because a firmware update was available that addressed the issues with Freesync. Then I discovered that I had to ship my two monitors 1,000km to the nearest Acer service center, for a price of over $100, to have a technician apply the firmware update.
Now I have updated firmware on all kinds of devices: dvd roms, ssd's, nic's, pcie firewire cards, routers, printers, and yes, even a monitor, more than once. I have never had a problem as a result of the upgrade process. I have bricked a couple of routers, but the problem was with the firmware, not with anything that went wrong with the actual application of the upgrade.
Firmware upgrades are par for the course these days. Just about any device you can name that has firmware will at some point require a firmware update to address specific issues. To require a customer to ship a device to a service center, at the customer's expense, to apply a firmware update, is flat out ridiculous.
If Acer thinks that there will be too many problems with people bricking their devices as a result of bad firmware updates, I can absolutely guarantee you that more devices will be damaged as a result of shipping, than will be bricked as a result of firmware updates, as long as the instructions for applying the updates are clear and concise.
Unless and until this policy changes I will never purchase another Acer product, and I will certainly not recommend Acer products to anyone else. I don't care if this post is deleted, as long as the message is passed along to representatives of Acer who have some responsibility for policy decisions of this nature...
