Just got the beauty today, very pleased with it on normal TV (on the decent quality Sky stations!) and thought it was time to connect it to the PC and watch some of the HD files. Sometime ago, I borrowed LG LCD HD capable screen, which I connected to the PC via DVI to DVI cable, turned on PC and watched it auto-detect the screen and set the resolution. The Win XP desktop looked cracking on it, as did the HD. This time, connected the DVI cable to Pioneer HDMI socket and turned on. May have missed it but never saw it say it had detected new screen, but it did boot up and display my desktop. However, looks rather poor, letters are poorly defined and the edges of the applications are off screen. If I run an application the FILE menu is just off screen if I go full screen, the bottom half of the task bar is off screen - that type of thing. Go into XP settings and it just has a PLUG & PLAY monitor as the display device, and try as I might I cannot get it to "detect" the Pioneer. nor can I res the resolution to the native for my panel. Tried using the nVideo desktop control video (for my FX 5600 Pro card) and try as I might, I could not get the crisp display I had on the LCD I borrowed. I could make the display larger or smaller in overall size, but could not get the detail I expected - the lettering on icons still looked p*s poor. Changing the resolution here had no effect apart from making the overall picture bigger or smaller. Each time I made a change in the nVidea software and the screen updated, the Pioneer "on screen" display popped on to say it was 720p, 1080i - but all that did was make overall display bigger or smaller. Frustrated - I turn to the good people here for help Am guessing I need to tell XP the monitor type I have plugged it into, but how???
