I bought 2 x CrossOver 27Q in May 2012.
Glad that both lasted till now. Actually one of them got a failed LED backlight PCB, which I managed to get it replaced.
One of the power adapter spoilt also and I replaced it.
On 12 Jul 2018, my other monitor's power adapter spoilt. Thankfully, I already got a spare 24V 5A power adapter, so change it and it is working again.
Now, I got a good problem. Both of this monitor are using Dual DVI. I am using Zotac GTX 970 8GB now and this graphic card has 2 x Dual DVI port. I tried to find a GTX 1070 / 1080 graphic card that has 2 x Dual DVI port but seems like none has it.
So in order for me to upgrade my graphic card, I will have to change both monitor also. I can get "Active DVI to Display Port" converter but they are like $150-$170 each. So really no point.
