Just a quick heads up on a few items in this thread. Refresh rate being reported as 59Hz is a well documented windows 7 "bug" (not problem). this is due to the monitor actually being a television, and reporting a television refresh rate to the PC. The refresh rate is actually 59.94Hz when 59Hz is reported.

also, regrading poor/different picture quality in HDMI vs. DVI connections.
For those that get a different PQ when connecting to an HDMI input on their monitor/TV. Many (not all) monitors process/scale any video signal that is input through an HDMI connection. Typically in these senarios, the monitor is expecting a video type signal 1080p/720p...ect. rather than a computer type signal 1920x1080@60Hz (which is not interpreted as the same signal in a monitor that can switch off the processor). That is basically what is trying to be conveyed in the link to Tomshardware posted by BradlyW. In this case, the poster in that thread had the ability to turn off the video signal processor in his TV, by renaming the input with a PC tag. Another poster in the thread actually had a setting in the menu system to indicate that the input signal was from a PC.
Monitor manufacturers have been slow to implement these type of settings in monitors that are sold as television sets.
So basicly, your results will vary on any signal input through HDMI, solely based on how the monitor manufacturer has implemented the input. As BradleyW noticed, it's not always a bad thing, (athough it does introduce delay), the video processing in the monitor/TV, actually smoothed out his video. Good for video, bad for gaming. Anytime you need to start to play with the overscan function in your graphic driver to fix the displayed image on your monitor, you can be pretty sure that your monitor is doing something with the signal it is receiving. Hopefully if you have this problem, there is a setting in the monitor to disable the video processing that is going on.Edited by xandypx - 10/24/11 at 8:04am
