Several burn-ins (e.g. from Youtube etc).
The only downside with getting a new C4/C5 panel is that the new panels are significantly narrower than the original C7 panel (for the 65″ I think the new panels are 12.6 mm narrower than the original one). Meaning that the edges will not align with the lower glass panel…. The picture quality should be really bad to sacrifice esthetics (Eclipse is a successful and timeless design IMO)!
If STBbrackets could have provided a 3 edges “click-on-frame” to fill in the 6.3mm width on each of the 3 sides for the new panel, I think upgrading would be a no-brainer!
