I have HLN617 with firmware 209 and run it through my HTPC with ATI 9800 Pro with Catalyst 3.7. It looks like 209 firmware does not have proper DVI driver, or Catalyst drivers when running 9800 Pro just have a problem with 209 and can not read it properly. Anyway, none of the Catalyst drivers (I believe the first one I used was 3.2) ever recognized Sammy as 1280x720 device. It was recognized as either 800x600, or more recently by 3.7 as 1280x768. So every time I upgrade drivers, I have to teach them [email protected] resolution via Powerstrip.
At first I tought Catalyst [email protected], and then never used Powerstip again letting XP manage resolution. Then I noticed that Powerstrip 3.4 had two 1280x720 timings within 60hz - one called "HDTV standard" and the other one "LCD". I played with both and noticed that LCD gave me better PQ. Then I upgraded to Powerstrip 3.45 (latest version) and this one has third option "DVI/HDCP derived". Well, this one works best with my system. On test patterns from VE and DVE it shows best resolution, color fidelity, etc. Was it possible that Sammy was re-scaling the image with other [email protected] timings?
Anybody had similar experiences? What are your timings for driving Sammy? Input will be appreciated.
