If computer with DVI is turned on first, TV won't wake up from standby mode. They are connected via DVI-HDMI cable. I had to call Tosh for several days. According to them, their engineers tested same configuration and had same problem. So they believe it is NORMAL with this TV. They said "You have turn TV first then turn DVI PC next" I cannot think that this can be normal for any TV. So I am going to return it. Be aware if you plan to use PC with DVI for this TV!!!!! You shouldn't buy this TV in such case. Another factor is, this tosh can do upto 1024x768 using pc monitor cable whereas Samsung 46" can do 1280x720 using pc monitor cable. With Tosh, I get full wide screen but stretched 1024x768. With Samsung, you get full wide screen at native 1280x720, no stretching. My colleague has Samsung so this is all facts. Please note that this is about PC RGB connection not HDMI. Where can I buy Samsung btw? My colleague bought it from comet at 1950 inc delivery.
