Conclusion
Samsung seldom put a foot wrong with their TV offerings these days, and in the UE55JS8500 they’ve crafted an enticing proposition for viewers wishing to board the High Dynamic Range train. The SUHD television boasts superb video processing, fluid motion handling, top-notch gaming responsiveness and of course HDR support, not to mention can be calibrated to a very high level of accuracy.
Versus the JS9000, the Samsung JS8500 obviously cannot undergo a One Connect Box hotswap to upgrade its processing. We also found the JS8?s pseudo-local dimming system to be slightly less effective than the JS9?s, therefore lessening the impact of HDR delivery. That said, the step-up model does cost at least £500 more. In any case, both are outstanding TVs, and we’re sure each will have its respective following depending on budget.
