Philips OLED910 vs LG G5: which discounted flagship TV should you buy?

If you’ve spent any time at all reading the TV reviews here on What Hi-Fi?, you’ll know that panel technology alone does not make a TV.

Even televisions that use the same panel can look vastly different from one another, and that’s before you consider all the other things – such as features, design and sound quality – that might sway a buying decision one way or the other.

When the LG G5 was released last year, it sent the Micro Lens Array (MLA) tech that had been behind its flagship panels for the last two years packing, and replaced it with new, cutting-edge Primary RGB Tandem OLED panel technology.

A few other TVs also bought into this tech – notably the Panasonic Z95B and the Philips OLED910 – and since we’ve already put the LG G5 and the Z95B up against one another, it’s high time we considered how the Philips OLED910 compares with its panelmate too. Let the battle begin.

Philips OLED910 vs LG G5: pricing

Considering the LG G6 is currently prepping itself for the shelves, the LG G5 is now much cheaper than it was at launch (though perhaps not as cheap as it will be in a couple of months).

This price would have brought it much closer to the original price of the Philips OLED910 if a recent price drop from Philips hadn’t widened that gap once again. That is, of course, if you live in the UK or Europe – Philip OLEDs aren’t available in the US or Australia.

We tested both of these TVs at 65 inches, and currently you can pick up that size of the LG G5 for around £2499, while the OLED910 is available for as little as £1799.

The 65-inch G5 has gone as low as £1899 in the past, but we've never seen it available for less than the OLED910.

If 65 inches doesn’t suit your space, you’ll have more choice on size with the G5, which is available in 48, 55, 77, 83 and 97 inches – though it’s worth noting that the 48- and 97-inch sets do not use the Primary RGB Tandem panel, and so therefore will not reach the same brightness levels.

That, perhaps, makes the fewer size choices of the Philips OLED910 less of an issue, with the 55- and 77-inch options, alongside the 65-inch set, most likely covering the screen sizes most people want – and at considerably lower prices.

When it comes to pricing, then, the Philips takes an easy win.

Winner: Philips OLED910

Philips OLED910 vs LG G5: design

Whatever design you prefer is the right answer to which is best, but we’d argue there is more to like about the design of the Philips OLED910 over the LG G5.

The Kvadrat fabric covering the under-screen speaker gives it a stylish, furniture-esque look, and four-sided Ambilight only adds to its flair.

The G5, by comparison, is as slim (2.4cm) and attractive as its predecessors – but it’s a design that has gone unchanged since the G1.

It feels ready for a makeover, but there’s absolutely nothing to dislike here otherwise. The Zero Gap wall mount makes for a super flush fit if you are looking to mount it, but if not, be sure to look out for the version that comes with the tabletop stand – in the UK, that’s currently only available for the 55- and 65-inch versions.

Slim and sleek is all well and good, but we have to pay the OLED910 its dues for its greater aesthetic consideration.

WINNER: Philips OLED910

Philips OLED910 vs LG G5: features

We already know that the LG G5 and the Philips OLED910 share the same super-bright Primary RGB Tandem OLED panel, with peak brightness claims of up to 4000 nits, but what in their feature lists separates them?

For a start, behind those panels are, of course, two different processors – the Philips 9th Gen P5 and LG’s Alpha 11 AI Processor Gen 2. Both are the companies’ most powerful TV chipset, with AI smarts on board that claim to offer a helping hand when it comes to making the picture and sound the very best for what you’re watching.

In the G5, that includes AI Picture Pro and AI Sound Pro, the former covering off a range of picture enhancements, such as AI Perceived Object Enhancer (which aims to boost the three-dimensionality of the picture), AI Super Upscaling and OLED Dynamic Tone Mapping.

LG has also installed an AI chatbot into the G5, which is on hand to help you get your picture how you want it, or solve issues with your TV. For those who don’t feel confident trawling through a settings menu, you can say things such as “my TV isn’t bright enough” to have the settings automatically adjusted.

For the OLED910, the on-board AI helps to classify what it is you’re watching and adapt the picture quality to suit. It also offers similar AI-judged improvements to things such as sharpness, colour vibrancy and contrast, though as always you can turn these off if you prefer.

Elsewhere, the Philips OLED910 continues its commendable commitment to supporting all four of the current HDR formats – that’s HDR10+ and Dolby Vision, alongside the basic HDR10 and HLG.

The G5, by comparison, only supports Dolby Vision, HDR10 and HLG. That covers off the majority of content, in honesty, but the additional support on the OLED910 does keep you covered for absolutely everything, and futureproofed too.

Where the Philips really loses ground is in its connectivity, and this has a particular impact on gamers.

On the LG G5, you have four full bandwidth HDMI 2.1 sockets, all capable of handling 4K/165Hz signals with VRR and ALLM (which covers off the 4K/120Hz max for consoles and 4K/144Hz for fancy PCs), while the OLED910 only has two, with a maximum limit of 4K/144Hz.

One of the HDMI 2.1 sockets also doubles as the eARC port, so you’ll be reduced to just one for your gaming machines if you need it for a soundbar or other sound system. That's not the end of the world if you don't mind any further devices being limited to 4K/60Hz, but it will be an annoyance to many gamers.

We’d also lean towards the LG G5’s webOS platform over the OLED910’s Google TV platform. For us, webOS wins on ease of use and speed, but it also offers a more comprehensive selection of streaming apps, with BBC iPlayer currently missing from Google TV.

It’s closely run in this section, with some wins on both sides. But we think the TV with the best, most impactful features for most users is the LG G5.

WINNER: LG G5

Philips OLED910 vs LG G5: picture quality

Given that both of these TVs received five-star reviews, you can imagine there’s little to grumble about in the way they handle pictures. However, even with the same panel behind them, there are differences in their delivery that might sway your buying decision.

Thanks to that new Primary RGB Tandem OLED panel, the G5 and OLED910 are noticeably brighter than their predecessors, and – most importantly – handle their additional nits well.

Philips does seem to put HDR levels of brightness behind SDR content on all of its picture modes though, which is something we wish was optional, even if it doesn’t impact the overall picture performance.

Colour handling is excellent on both, with punchy and vibrant pictures that clearly benefit from the additional colour volume afforded by this panel. There’s the occasional oversaturation of skin tones in some scenes on the Philips OLED910 that we don’t notice as much in the G5, but overall both sets balance vibrancy and accuracy with few complaints.

Both offer Filmmaker Mode alongside a whole host of other picture options – it’s the picture setting we recommend, since it is the most accurate and usually switches off all additional processing. However, we actually found the OLED910 leaves some of it turned on, mostly for helping the TV to look its best at various levels of ambient lighting.

It’s worth experimenting here and deciding for yourself if there’s any positive impact, but if you’re particularly against any form of added processing, some extra care will be required in the OLED910’s menus to make sure it’s all off.

You can expect sharp, detailed and insightful pictures from both TVs. If pushed, we’d say the Philips gets closer to the solidity and three dimensionism of the Award-winning Sony Bravia 8 II, which is also helped by the OLED910’s better handling of dark scenes – there’s a slight black crush from the LG G5 that means you lose some shadow details in the darkest parts of a picture.

Overall there are some pros and cons for both TVs, but both offer a superb picture with lots to like. We’re chalking this one up as a draw.

Winner: draw

Philips OLED910 vs LG G5: sound quality

While these TVs might come close in picture quality, when it comes to sound quality, there is a clear winner.

The LG G5 offers a 60W 4.2-channel system, while the Philips OLED910 has a 3.1-channel 81W system, produced by B&W, that sits underneath the screen like a soundbar.

Overall, the G5’s performance is disappointing. Even with our preferred Cinema preset, it just isn’t able to dig deep and deliver much bass at all, nor is it very assured with low-level dynamics, meaning dialogue often sounds lifeless and dull.

It’s a really unexciting sound, which means, without a doubt, you’ll need to add to the G5 by way of a soundbar or surround sound system.

However, the Philips OLED910 proves that not all TV sound has to be bad, and manages to deliver a wide, detailed sound, with good effect placement (even with Atmos sounds), impressive weight and a really lovely tonal balance by TV standards.

Dynamics are impressive for a TV too, and there’s a much better handling of low-level dynamics, meaning voices have realism and character, while bigger volume changes are handled well too.

There’s a little softness to deep bass, but you’ll be hard pushed to find a TV that sounds better.

Of course, a good soundbar will be even better, but you’d need to invest in something around the level of the Sonos Arc Ultra for a significant upgrade on what this TV can do.

WINNER: Philips OLED910

Philips OLED910 vs LG G5: verdict

As always, there can only be one winner, and given how close these TVs come in key areas such as picture quality, the value offered by the Philips OLED910 is hard to ignore.

Throw in nice-to-haves such as Ambilight, a pretty great built-in sound system and a living room-friendly design, and that saving over the G5 starts to look even tastier.

However, this particular head to head isn’t cut and dried by any means, and if gaming is a key consideration for you, we might be inclined to recommend the LG G5 because of the additional HDMI 2.1 ports.

The better smart system and full complement of catch up apps is also a mark in the G5’s column, as is that stunningly slim wall-mounted design, which might be worth the additional outlay.

Still, the Philips OLED910 is to be applauded for how much it offers at such a great price.

Getting a 65-inch TV with a performance this good for well under the £2000 mark is nothing short of a bargain. If you choose it as your next TV, we think you’ll be very happy indeed.

OVERALL WINNER: Philips OLED910
