20150604 - Panasonic CT-34WX59 = Piece of Junk


Waiting for "Updating dependencies...", time to reflect on a fail while CRT hunting...
Majority mass market consumer "HDTV ready" CRTs closing out the CRT TV era scanned out 1080i using an aperture grille (and some with a shadow mask) which could never resolve 1920x. Because of that they were effectively 960x540p displays limited to a smaller resolution by overscan. This is not a problem, this is exactly what I wanted. The CT-34WX59 is a 34" 16:9 CRT which can do 896x512 displayable at 60Hz via an HDMI cable and a custom modeline. I grabbed it for $10 on Craigslist. That was a 180 lbs mistake. I knew the display had a sharpen control, I didn't know Panasonic's idea of sharpen=0 adds ringing to everything: they don't support fully turn sharpening off. Some Panasonic displays don't have a Scan Velocity Modulation (SVM) disable, so just in case I opened up the TV and un-did the physical connector which I believed was for the SVM feature: didn't fix it. Attempted to find an override in the service menu, nothing there. Did some more testing: all 1920x1080i, 1920x540p, or 960x540p based modelines all get the same over-sharpening effect. Effectively this display was garbage even when new, avoid Panasonic when CRT hunting...
