I am having a problem with my JVC AV-48WP74 RPTV connected by DVI to Radeon 9600XT (WinXP Pro with Radeon 4.10 drivers). The vidcard automatically detects a 1080i monitor and sets the resolution as such(1980x1080i). But on any open windows there is severe flickering, to the point where text is unreadable (ie. in I.E.). I can switch the display to 1280x720p, which eliminates the flicker but still gives severe overscan, distortion at the edges, and is somewhat fuzzy. Using Powerstrip to shrink the display dimensions, shows the distortion. I think it may be downconverting it to 480p.


I have powerstrip and would like to run 1776x1000i in 1980x1080i timings if I could just get rid of the flickering. I have a hunch that the scan rate (vertical) of the vid card is not exactly matching the one for my display, but I'm afraid to mess with it for fear of destroying my TV. Is there anyone out there that can help or has any ideas/comments on the matter?


For reference, the rest of my system is:


AMD Athlon XP 2600+

Asus A7N8X-E Deluxe (w/ SoundStorm audio via digital coax to receiver)

2x256MB PC2700 RAM

Sapphire Radeon 9600XT

200GB Maxtor (8MB buffer)

Windows XP Pro SP2

Catalyst 4.10 (w/Control Panels)

nForce 5.10 drivers


Any help would be appreciated

I guess that's what I'm asking...I don't see flicker with HDTV in 1080i, nor with SD material in 480i, but that's through my component inputs. I've seen in another thread someone said that 1776x1000i results in much less flicker on their RPTV, so I'll try that tonight.


I'd still like to hear some input on what I can expect to get from this. I'd hate to think that I'd spent $500+ to upgrade my PC and can't even get picture that's really any better than an S-video image out of it.


Also, on a unrelated note, does anyone have any recommendations as to what setting(s) in ffdshow would be best to remove blockiness/pixelation in DivX movies. I know I can't increase the image resolution (not talking about image resize), but I'm just looking to clean up the images, as they are very "noisy" and blocky around certain lines (like the large credits at the beginning of a movie). My guess is I'm probably looking for some kind of noise filter, but there are an awful lot of them (noise, 3dNoise, luma/chroma sharpen, etc.) in many different categories. I'm kind of a newb at ffdshow, so I'd appreciate any help.


Thanks in advance...
