Chinese manufacturer TCL has announced not one but two new TV lines to add to its already substantial stable of television models. As of today, the new TCL P638K (ranging from 43” to 75”) series and the C645K series (ranging from 43” to 75”) is available via Argos' online store, with prices starting at an exceptionally low £269.

We'll start with the cheaper TCL P638K, a 4K HDR model which combines HDR10 and 60Hz Motion Clarity for what the manufacturer teases will be a "detailed and smooth picture quality". The P638K is further fitted out with multiple HDMI inputs, Auto Low Latency Mode and support for the HDR10 format (obviously).

It's also furnished with TCL's 'Game Master' mode which, according to the brand's official website, 'enhances your gaming experience by turning off the video processing on the TV for smoother visuals'. Essentially this appears to just be an ALLM feature, unlike the 'Game Master Pro' mode seen on higher-end models such as the Award-winning TCL C845K, which adds VRR.

As is the norm these days, the P638K is fully operational as a Smart TV, boasting what TCL claims is its 'most advanced system ever', with Android TV and Google Assistant both baked in as standard.

Moving over to the slightly more expensive TCL C645K, it's a similar story in terms of features and connectivity options, although there are a few added tricks and treats that go some way to justifying that slightly increased price tag. The C645K, for instance, features TCL's AMD FreeSync tech for smoother gameplay with fewer artefacts at pretty much any frame rate, reducing those pesky issues with choppy rates and janky rendering that can pull you out of your session on Elden Ring.

The C645K also packs in Dual Line Gate technology (DLG), which essentially auto-adjusts on-screen content for a higher refresh rate and lower latency. Like the P638K, the more premium model utilises Android TV software and comes with Google TV and built-in Google Assistant for hands-free voice control.

One of the big distinctions with the more expensive model is the inclusion of QLED. Peak brightness is still only a claimed 450 nits, but the C645K's Quantum Dots should allow it to reproduce better and more vibrant colours. HDR support is widened to include Dolby Vision and HDR10+, which should help with the right content, too.

Currently on sale online at Argos, the TCL P638K Series is available in the following sizes:

43 inches: £269
50 inches: £319
55 inches: £349
65 inches: £439
75 inches: £749

The TCL C645K Series, meanwhile, is available in the following sizes:

43 inches: £329
50 inches: £359
