I completely passed on the plasma & LED/LCD waves (so I could finally finish my degree), and it looks like my rusty/trusty old Toshiba 50HX81 rptv is now showing signs that a failure may be close-at-hand. I've done a bit of reading here and elsewhere, so now I'm posting to get some well-considered opinions. Budget-wise, $2k is about as high as I'm willing to consider, and I'm not really loyal to any particular brand. I've decided I'd like to jump on the 4K bandwagon despite the minimal content, and a 55" panel is the preferred starting point. I'm leaning toward OLED, but the reports I've read regarding burn-in and reduced brightness over time makes me wonder if I should sacrifice black levels for panel longevity in an LED display. (As it is, I can see evidence of pillar-box burn-in on my RPTV from extended viewing of TCM programming.) All I need is a reasonably good display for general-purpose viewing (and console/PC gaming)--not the best of the best like a Sony A9F, but something that's maybe a step or 2 down from that? SmartTV is a convergence of functions I really could do without. Dolby Vision & HDR would be nice to have, though. Thoughts?
