The RS530K is available in either 32in or 40in and looks relatively similar in terms of specifications. It also has a 60Hz panel but the resolution is FHD (1,920 x 1,080) rather than UHD (3,840 x 2,160). Similarly, while there is support for the HDR10 and HLG formats, you don’t get the more advanced HDR10+ and Dolby Vision format support found with the RC630K.

Sound is inferior to that of the C845, with the subwoofer omitted to leave a two-channel 30W system that’s Dolby Atmos compatible. TCL tells us that the main difference is in the design, with the P715K being "more premium" in that regard. However, the P615K doesn't have the hands-free voice control support offered in the P715K either. Roku took care of the streaming side of this TV, so there's a wide selection of services to choose from.

The most affordable new entry in TCL’s lineup is the C645 series. There’s still support for HLG, HDR 10, HDR 10+ and Dolby Vision IQ, but the quantum dot LED panel does without FALD and has a native refresh rate of 60Hz. The 43EP658’s quad-core processor drives an Android 9.0 operating system and Android TV smart TV interface – which is, let’s be honest, a better and more sophisticated specification than the TCL’s price might suggest is possible. The audio setup is the same as that of the C745, with two 15W speakers that support DTS-HD, DTS Virtual:X and Dolby Atmos.

The World’s End is an HDR10+ master, with all the theoretical advantages the dynamic metadata standard offers. But the TCL’s HDR compatibility extends only as far as HLG and HDR10. So the occasional bit of BBC iPlayer 4K content (Seven Worlds, One Planet for instance) is maximised by the 43EP658 – at least as far as that’s possible with a 300-nit peak brightness. But it can only apply HDR10 static metadata to the HDR10+ disc, and as a consequence some of the luminosity and detail lurking in the dingy interiors of the film’s numerous pubs is left behind.

This SmartTV promises to keep you entertained. Equipped with Freeview Play, whichgives you the biggest shows live and on demand all together in one place for free, provides over 70 TV channels, 15 HD channels and seven on-demand players. It also has theAndroid 9.0 operating system – featuring apps like Google Home, YouTube, Disney+ and Netflix in glorious 4K resolution.Not only can you add more apps from its vast library, but it is also easy to integrate withanandroid smart phone.Although its android-based technology may not be the easiest menu system for many users, for those looking for extra apps and a little more from their TV, is certainly givesyoumore! Chintzy remote aside, TCL's 4-Series should work for people who want 4K and HDR support without going broke. Its image quality is probably going to be more than good enough for a large majority of its intended audience and it scales all the way up to 75 inches. Sound TL;DR Not as unpleasant as some alternative TVs, but still not really up to much Other panels to ponder

There are of course a few key differences between the 2022 and 2023 models. The C835K can’t hit the same levels of brightness as its successor, with peak brightness of 1,500 nits compared to 2,000 nits. It also uses an older processor – AiPQ 2.0 – meaning HDR tone-mapping and general processing aren’t quite as impressive. There’s no 98in option either, and the speaker system is powered differently, with two 15W drivers and a single 30W driver in place of the pair of 25W drivers and single 20W driver on the C835K.Some quite fundamental audio/video syncing problems manifest themselves, too. The TCL doesn’t have any problems keeping the pictures and the sound of an off-air broadcast synchronised, but content delivered either by disc or by streaming service can fall out of harmony. If your disc player, like the Samsung UBD-M9500 used for the majority of this test, has some adjustment in terms of sound delay this trait can be overcome. But for streamed content, all the viewer can do is watch the mouths move and wait for the dialogue to come. The C635K also runs the AiPQ 2.0 processor and is able to hit a peak brightness of 500 nits, which is actually slightly higher than the 450 nits the C645K is rated at. Like the two 2022 models above, the C635K runs the Android TV operating system rather than Google TV.
