Query: Bad performance

I have tried to use these adapters for the last six months at work and at home. My company ordered several of them recently but we had to give up on them. I tried them with my home laptop and the same results.The laptops crashed very often (BSD) for no reason, and also when trying to open .mov files. The resolution is not good, and the refresh rate is very slow. I work for the IT department, and I tried to troubleshoot it by contacting the Tritton tech service. I installed the newest drivers/firmware. No luck. I had to return the device.Note: Our company tried a couple other adapters but they had the same performance. We had to buy DVI connectors and use docking stations.If you are looking for an adapter with great definition, and great performance try something else.
