di po ba apektado rin ang viewing distance nun kung galing ka sa 42 to 50 tpos ganun pa rin ang viewing distance mo katulad nun 42 pa lng ang t.v mo? tpos 50 ang palit mo so sa palagay nyo mas maappreciate yun pq kung same distance lng ang paglalagyan nyo ng t.v.?
Only kung MALAPIT ka masyado. Natural you'd see more of the "lines" ng bigger non-full HD panel if your viewing distance is close enough.
For example ne (this applies to full HD panels pero pareho rin ang basic idea). For a 42V panel, you can watch as close as 1.6 meters at optimum IQ. For a 50V panel, the minimum viewing distance for optimum IQ is 1.9 meters. So kung dati ka nang umuupo at 1.6 meters then upgraded to 50V, meron degradation sa IQ.
Sa kabilang dako, you can sit as far as you want, farther than the minimum viewing distance and the IQ would remain the same. Kase hindi na visible ang inherent imperfections ng non-full HD screen as you move away from it. Of course, liliit nga lang ang screen as you sit farther. So kung dati nang malayo ang upuan mo, upgrading from a 42V to a 50V non-full HD should NOT change the IQ. Lalaki ang nakikita mong screen by about 1.45X. Same IQ, bigger size - eh di mas maganda diba.
