Question about Samsung LS49A950UIUXEN

Hello. Yes, the KVM/USB Hub is very very unreliable.
I have opened a ticket with samsung, but nonreal solution was provided.. instead of fixing the issues they explained me a lot of „bla bla“ why it‘s normal to be so unreliable. I was writting them about the following:
- USB Hub is only working on USB 2.1 speeds when high resolution is activated
- USB devices are unresponsive 5-10 seconds after the monitor wakes up
- sometimes, after the monitor wakes up, the usb hub does not work at all and I have to restart it
- sometimes, after sleeping over night, in the morning my laptop wakes up from sleep but the monitor is totally unresponsive. Buttons are useless - you have to plug out the power cable for 2 seconds
- automatic source detection and switching works only in maximum 10% of the cases - really shameful
- when the monitor is sleeping, you have to randomly press the buttons for 10-15 seconds before any menu pops-out on the screen on order to manually select the new source, because the new source is not detected automatically

The light bleeding is awful. I feel that the monitor is like an awful cheap products where they sell numbers but with horrible user experience

And I am not a critical guy, but this time I am really disappointed
