With their combination of a sleek, Ambilight-enhanced design, competitive pricing and uniquely punchy pictures, Philips’ award-winning 2018 OLED 
flatscreens were hard to resist. That hasn’t stopped 
the brand from taking things up another gear with its 2019 models, though.

The first improvement that stands out on the new 55in 55OLED804 is Dolby Vision compatibility. This would be welcome on any TV, but it’s given extra significance here by the fact that Philips has also supported the rival HDR10+ format since last year.

Dolby Vision and HDR10+ are dynamic HDR variants that add extra scene-by-scene data to help TVs deliver more accurate images. Yet Philips is the only brand, 
bar Panasonic, accommodating both systems, meaning 55OLED804 owners will always get the best picture quality a stream or 4K Blu-ray has to offer, no matter what format it’s mastered in. It'd be a boon if all TV brands would take such a consumer-facing, format-neutral approach.

Philips has also further upgraded its already powerful P5 picture processing engine. This introduces a whole second processing chip’s worth of extra power, and improvements to three of the five picture ‘pillars’ that 
give P5 its name. For starters, Philips' Perfect Natural Reality (PNR) system for converting standard dynamic range images to HDR now supports specular detection (for picking out and emphasising bright spots of light); region classification (to localise the way the HDR upgrade is applied); and skin tone protection (so that skin tones are detected and preserved during PNR’s colour-widening process).

The revised P5 processor brings new detail protection and restoration features too, as well as a system for removing jaggedness from angled lines. This all adds up 
to more apparent detail and image depth.

Tweaked noise reduction systems, says Philips, now reduce contouring and deliver more intelligent bit-depth calculation, while new ‘sparse filtering’ stops noise reduction generating unwanted side effects such as softened motion sharpness.

And there are also some improvements specific 
to playback of native HDR content. Namely better reproduction of shadow detail in dark areas (which at times appeared rather crushed on last year’s models); enhanced colour and contrast; brighter light peaks; less banding noise over fine colour blends; and less detail loss in the brightest parts of aggressive HDR images.

Philips 55OLED804 design and smart features
The 55OLED804 looks gorgeous. The screen is surrounded by a minimalist dark frame, offset by an attractive metallic outer trim. It sits low on a pair of chrome bar feet, while most of the panel’s rear is sensationally slim and beautifully finished in brushed metal.

This classy design is boosted by Ambilight, which casts coloured light from three of the screen’s sides to create 
a relaxing and immersive experience (but do reduce the light’s intensity slightly from its default setting).

Audio comes from a 2.1-channel array with tweeters 
and midbass joined by a rear-mounted woofer. This will hopefully see the 55OLED804 get mileage out of the built-in Dolby Atmos decoder Philips has added this year.

The set's remote features a reasonably logical layout, direct buttons for Netflix, Rakuten and voice search, 
and a full QWERTY keyboard on the back – although 
the need for this is reduced by built-in Google Assistant voice recognition (Amazon Alexa is also supported via external devices).

Smarts on the 55OLED804 come courtesy of Android TV. The latest Oreo version improves over previous generations, particularly relating to customisation options and the emphasis given to video services. Amazon Video, Netflix, Rakuten, BBC iPlayer, GooglePlay Movies, and YouTube are all present and correct. While the ITV Hub suddenly appeared during my time with the TV, Android still doesn’t support the All4 or My 5 catchup TV services.

And I still find the system frustrating. The home page takes over the whole screen and won’t let you return to what you were watching simply by pressing the Back key. 
It runs relatively stably on Philips' TVs, though.

Philips 55OLED804 performance
The 55OLED804’s pictures instantly look superior to those of its predecessor. Thanks, chiefly, to some extra precision and control.

This is at its most obvious when it comes to contrast. 
As revealed during the tough sequence in Sapper Morton’s kitchen near the start of Blade Runner 2049 (4K Blu-ray), this new Philips does a better job of retaining subtlety in shadowy areas, like the shaded half of K’s face, and the unlit corners of the room.

The improved specular highlight system is also evident in the shot where K’s Spinner flies towards Morton’s abode, as tiny lights on a distant hillside glimmer with intensity and precision.

Without being able to do side-by-side comparisons, I’d say that baseline brightness levels with HDR content seem slightly lower than they were on the 2018 OLED803. However, refinement in the darkest and brightest parts of the picture lead to a more consistent, natural and dynamic-feeling image.

It’s a similar situation with colour. There’s less banding – pretty much zero, in fact – in tricky shots such as the dusk beach scene in Exodus: Gods and Kings (4K Blu-ray), or the ultra-bright white clouds throughout the UHD BD of Pan. This produces a more precise look to shading and blending, even if outside of Philips' Vivid preset colour tones don’t always feel as flat-out intense as they did last year.

For much of the time the aforementioned Vivid mode delivers the most eye-catching, punchy pictures. But it can go too far at times. Extreme content, such as the sun-drenched clouds when Peter arrives in Neverland, looks clipped and blown, while the sand in Mad Max: Fury Road (4K BD) can appear almost like it’s been painted orange.

There are tools to help you calm the Vivid mode down, but other presets offer outstanding results with a near-perfect balance of dynamism, subtlety and consistency. And noticeable in all of them is the impact of Philips' new skin tone processing, which gives faces a more believable and refined look. Mad Max: Fury Road no longer have a distracting fizzy feel. This 
is true even without using Philips’ noise reduction system, although I'd suggest you can set this to Minimum without having to worry about unwanted side effects.

The 55OLED804’s enhanced image precision versus 2018’s models is underlined by its Dolby Vision and HDR10+ support. These both bring subtle improvements to dynamic range and, in Dolby Vision’s case, colour refinement. Unexpectedly, the TV is able to apply some of Philips’ own video tweakery to Dolby Vision images, rather than 
the Dolby mode disabling TV processing, as it usually 
does. Dolby Vision Bright retains Philips’ source analysis, sharpness enhancement and motion processing systems. The Dolby Vision Dark preset turns off all the Philips processing if you prefer.

If you do plump for the Bright mode, I’d recommend switching motion processing from Standard to Movie, 
as Standard does generate artefacts.

With my Oppo UDP-205 4K Blu-ray player, dark Dolby Vision scenes appeared on the 55OLED804 with strangely elevated black levels. Switching to a Panasonic DP-UB820 resulted in no such problems. In fact, with this deck Dolby Vision delivered just the sort of extra dynamism (deeper blacks, punchier peaks) I’d hope to see. Philips is investigating the Oppo Dolby Vision issue, but hadn’t confirmed a fix by the time of writing.

The TV's brightness on a white 10 per cent HDR window in HDR Personal mode measured 750 nits briefly, before dropping to around 640. In Vivid mode it hits nearly 900 nits, settling down to around 770. In HDR Movie mode, 
the set is stable at 650 nits.

While I'm talking measurements, input lag over HDMI was around 32ms when using the TV’s Game picture preset.

Away from 4K HDR, the set's processing works wonders on standard dynamic range/HD content. Detail levels approach those of true 4K, without exaggerating noise 
or adding grittiness. The Perfect Natural Reality HDR conversion system, meanwhile, introduces a nicely judged increase in an SDR picture's brightness range without excessive or yellowy white peaks or black crush. So while 
I understand the purist appeal of leaving SDR images relatively untouched, I think you’ll struggle to live without PNR once you’ve tried it. Again I’d suggest sticking with the Minimum setting, though.

Where this TV falters is with its audio. In the plus column there’s an impressive amount of detail and scale to the soundstage, especially if you call in the (off by default) Dolby Atmos height option. And vocals sound surprisingly clear for a TV with no forward-firing speakers. A lack of bass leaves its delivery feeling a bit thin, however – even 
to the point of harshness with some settings or very dense mixes. Add an external sound system if you can.

Philips 55OLED804 verdict
Accepting this caveat (and my gripes about Android TV), I'd say Philips has again struck gold with the 55OLED804. It's keenly priced, offers slightly less aggressive but much more refined pictures than its predecessors, has Ambilight and Philips’ processing power to set it apart from OLED rivals, and, best of all, its support for both HDR10+ and Dolby Vision shows an admirable desire to give AV fans what they want. Impressive.
