In addition to the recommendations such as James', it may be worth some time looking at teardown videos (YouTube, iFixit, etc.) and FCC filings (the internal photos entry among all of the documents) to get an idea of construction. You won't know if you get a similarly well-performing sample like James' or an out-of-spec dud when you make the purchase decision.....unless 17 other PSTC members recommend the same make/model. ;-)
Also, maybe a colleague on the list would have insight for the construction of medical class 4K displays versus consumer class in the event there are better regulatory margins that accompany the grayscale/color rendering performance requirements (whether implemented in hardware or firmware). >From my experience, there has been a shift in the display industry when looking at internal construction where ferrite beads, metal foil tapes, outer metal chassis have disappeared and it's now an LCD panel with its own regulatory behaviors and several PCBs (power supply, TCON, scaler, WiFi, etc.) bolted on the back with a mix of flex and discrete wire harnesses....all covered by a rear plastic cover. Some of the shift is a function of moving from CCFL to LED backlighting, some from having strictly digital I/O and probably a few other factors like better PCB design/layout to ensure robust high speed I/O performance. And a last option depending on time/$$ for comparison testing may be to use a different display load (projector, HDMI extender, etc.) to understand the relative behaviors. -Adam in Atlanta On Tue, Jan 10, 2017 at 5:30 AM, Pawson, James <[email protected]> wrote: > Hi Brent, > > > > I’ve had some success with a (now slightly old) Samsung 4k TV that wasn’t > too noisy, model UE48JU7000T. > > > > James > > > > > > > > *From:* Brent DeWitt [mailto:[email protected]] > *Sent:* 10 January 2017 01:57 > *To:* [email protected] > *Subject:* [PSES] lowest emissions 4k TV? > > > > Hi group, > > > > Any suggestions on the best available 4k TV for emissions testing > support?
