From Forbes/John Archer's review:
Its the extra brightness LG has unearthed for 2017 that makes the most immediate impact. Whereas last year I found LG’s OLED TVs tending to leave high dynamic range content looking a little dark and prone to over-dominant black levels, this year you get not only a much more pronounced appreciation of the difference between HDR and SDR content, but also a much more balanced HDR picture. Now the much punchier brightness peaks share screen space effortlessly with more detailed, richer-looking dark areas, with neither seeming to dominate the other.
The OLED65E7 can also resolve much more detailing in bright areas. But crucially the OLED65E7 reduces this problem sufficiently that it only seldom caught my eye during my time with the set, whereas it was a routine distraction on last year’s models.
We’re used now to OLED TVs being able to deliver near perfect black colors under pretty specific content conditions. But the way the OLED65E7 delivers much defter and more extensive control over ‘near black’ light reproduction greatly expands those conditions, so that you’re far less likely to have the picture suddenly slip into greyness, or exhibit noise and/or a lack of tonal finesse in very dark areas.
There’s no overstating how much the OLED65E7’s more stable blacks improves the viewing experience, especially in combination with the enhanced brightness. It feels like OLED has gone from a display technology that can always cause jaws to drop in specific demo situations to one which can pretty much always cause jaws to drop in real-world, every day situations too.
TVs that deliver great black levels usually deliver ultra vibrant and rich-looking colors, and this is emphatically true of the OLED65E7. In fact, thanks to the extra brightness and more consistent and controlled black levels LG has delivered on its OLED TVs this year, the OLED65E7 joins the W7 in producing colors that look far more potent and rich than any I’ve witnessed on any previous OLED generation.
In fact, the OLED65E7’s handling of the wide color ranges on Ultra HD Blu-rays at times - usually when it comes to mid-bright and dark colors - looks slightly richer than that of Samsung’s Q9F TV.
We’re not done with the OLED65E7’s strengths yet, either. Its native 4K pictures look slightly crisper and more detailed than those of last year’s models. Its upscaled pictures look much more detailed and crisp than those of last year’s OLEDs.
In fact, colors look more stable off-axis than they did on 2016’s OLED TVs.
Motion is handled more cleanly. Color noise levels are generally much less aggressive than they were on last year’s sets. And finally, in a move which comes as a huge relief after the problems LG’s OLED TVs caused for gamers last year, input lag in HDR and SDR game modes is now limited to an excellent 21ms.
The really important thing about the OLED65E7 is that its picture glories are much more wide-ranging and all-encompassing than they were on last year’s OLED sets, meaning it delivers one of the most entrancing and flat-out beautiful images I’ve ever had the good fortune to clap eyes on.
