What does the COR Score mean?
One consistent scale makes different publishers’ ratings easier to compare. The original review still tells you why a critic reached that verdict.

Check the match
Identify the TV range and the version reviewed. Check the reviewed version alongside the specifications for your chosen size.
Compare on one scale
Convert usable ratings to five points, count each publisher once and give each critic equal weight.
Require three critics
Show the average to two decimal places after three distinct critics. Otherwise display tbd, keeping individual reviews visible.
Find the best fit by considering the score alongside the critic count, review dates, tested size and the strengths that matter to you. A range score brings together the included reviews; it is not a separate test of every screen size.

Your questions, answered
TCL C745K FAQs
How many expert reviews are available for TCL C745K?
This page currently includes 2 scored critic reviews. Each publisher counts once. Follow the review cards for the original verdict and the version that was tested.
What is the COR Score for TCL C745K?
The COR Score is tbd. We publish a combined score only after at least three distinct critics have usable ratings. Any individual reviews already available remain visible.
Which UK versions of TCL C745K are listed?
The verified model options are 55-inch 55C745K, 75-inch 75C745K. Select the exact code in the specification section. A range review does not establish that each screen size was tested separately.
How should I compare retailer offers?
Match the complete UK model code, screen size, condition and included accessories. Check delivery, stock and the final total at the retailer. Search links help you find listings and are labelled separately from matched price offers.
Do all screen sizes have the same specifications?
Check the panel for your exact UK model. Dimensions, mounting points, accessories and other features can vary by size. Selecting a size also selects that model in the buying panel.
What is the difference between native refresh rate and VRR?
Native refresh rate describes the panel’s normal refresh specification. VRR lets the refresh rate follow a compatible game signal within a supported range. A quoted VRR maximum is not the native rate; check the source device, resolution and input together.
How do I check that this TV will fit my room?
Use the width and height for your selected model, then check the stand footprint or VESA mounting pattern. Allow room for cables and ventilation using the manufacturer’s installation guidance.
Should I add a soundbar?
Read the critic’s sound assessment first. A soundbar may suit a larger room or a preference for stronger bass and clearer dialogue. Check the TV and soundbar connection requirements, including eARC where supported.
Does every critic review cover my selected size?
The COR Score brings together reviews of the model range. Each card identifies the tested version where the publisher provides it. Use size-specific findings alongside the specification panel for the model you intend to buy.
Where can I compare other TVs?
Use the comparison table and TV buying guides on this page, or browse the TV category and brand directory. Compare review evidence, the features you will use and available prices together.
