Here is my issue.  I am running P3D on a 40" UHDTV.  using a Titan X video card.  Everything is perfect - but at 80% zoom, my primary gauge/display on my QW787 measures only 8" wide x ~7" high .  On a real 787 it is 12" wide x 9" high.  It seems we can't really fly at 100% zoom - because it will crop out eiter the bottom of the gauges or anything above the horizon.  So 80% seems optimal.  So going to a 55" UHDTV should give me bigger gauges?? 

Has anyone used a 55" UHDTV?  If so 

1. Would I see a big performance hit going from 40" to 55"?

2.  How big are your primary gauge/display on the 787? or even the 747 using 80% zoom)   I'd love to know so I can compare

You wouldn't see any performance hit, the number of pixels is the same. As for the rest, you have it figured out. To display something at life size the screen needs to be big enough to show the bits you want to see at life-size. This generally requires some compromise. The most convenient compromise is to simulate the out-of-the-window display only, which lends itself reasonably well to using a multi-monitor setup such as I use in my cockpit. But that means doing the panel some other way, maybe on another screen or screens. If you want the virtual cockpit, you really need a very big display and a head tracker. The only alternative is to go full surround with projectors, which will also mean compromising on the resolution and brightness.
