    Arrow Anyone here consider themselves good at Audio/Video?

    Long story short, I have a GTX 285 OC with HDMI out to a 32" Sony Bravia KDL-32EX400 and when I play games and turn my character quickly, there is a momentary visual effect that I can explain no better than as the "green" channel of the RGB pixels being too "slow" to catch up and leaves a trail for but a fraction of a second.

    This isn't the biggest issue (aside from that, using it for browsing, Photoshop, etc, it looks gorgeous at 1920x1080)

    Anyone know what this could be? I've updated it to the latest firmware, the specs looked good on it (1920x1080, 60Hz)

    I have no idea what the response time is since Sony doesn't seem to list that, but could that be what's causing this issue?

    Sounds to me like a driver issue, I've had that problem before with NVIDIA chipsets.

    Have you checked to see if you have the latest driver version? (On their website).

    Yeah. I got the latest drivers. Don't know about settings in the nVidia control panel that would help with this.

    I also found the code to get into the TV's service menu:

    left, right, mute, center, mute, menu.

    There's a couple options in here, most notably separate RGB Gains and separate RGB Offsets, but I don't know what these do, and secondly, they don't seem to stick after I've changed them.

    what if you lower the resolution? it sounds like a response issue to me , like ghosting, but green chan ghosting is far more present on plasma

    I connected my computer to a regular LCD monitor (24" LG 1920x1200) but had to use a DVI to DVI cable (rather than my 32" Sony's DVI to HDMI cable) On that screen there was no ghosting.

    I've tried lowering the resolution, but it doesn't help. The "response time" sounds like the culprit, but I've no way of knowing what the Sony TV's is.

    One would have to think that a 1920x1200 32" LCD Monitor going for $1000 and a $500 32" 1920x1080 TV as a monitor would HAVE to have SOME differences in them. (The TV does have a lower DPI of about 60 compared to the monitor's 90) A slower response time may be another difference, but oddly, Sony doesn't show response times on any of their models.
