The verdict
A new C4 at a sizeable discount is still a strong OLED, with measured peak brightness around 1,050 to 1,150 nits on the 65-inch. LG's own store listed every size as out of stock on the day this was checked, and this research did not verify current retailer stock, so confirm it is new, carries the standard warranty and costs clearly less than the C5 or C6 before buying. The 42 and 48-inch sizes do not list the Brightness Booster feature.
The LG C4 is the 2024 model of LG's popular C-series OLED, sold in 42, 48, 55, 65, 77 and 83 inches. It uses an Alpha 9 Gen7 processor, a WOLED panel, webOS 24 and four HDMI inputs listed for 4K 120Hz with VRR up to 144Hz. Reviewers praised its brightness jump over the C3, its gaming features and its webOS software, but noted ordinary sound and a missing HDR10+ and ATSC 3.0 tuner.
Strengths
- Tom's Guide and Trusted Reviews measured about 1,049 and 1,150 nits of HDR peak brightness on a 10% window, a clear step up from the C3.
- Four HDMI inputs listed for 4K 120Hz with VRR up to 144Hz, and Boost-mode input lag of 9.2ms in Tom's Guide's lab.
- Dolby Vision, HDR10 and HLG are supported, with AirPlay 2, Google Cast and the webOS 24 platform.
- Six sizes from 42 to 83 inches, including a compact 42-inch.
- What Hi-Fi called the picture a big improvement on the C3 in brightness and sharpness.
Weak spots
- Tom's Guide called the built-in sound ordinary, so plan on a soundbar.
- No HDR10+ and no ATSC 3.0 tuner.
- Two generations behind: the C5 and C6 add newer processors and, on the C6, 165Hz gaming.
- Wi-Fi 5 and Bluetooth 5.1, older than the Wi-Fi 6E and Bluetooth 5.3 on the 2025 models.
- LG's US store showed every size out of stock when checked, so supply depends on remaining retailer inventory.
Great for
- Buyers who find a new C4 at a clearly lower price than the C5
- Console and PC gamers who want 4K 120Hz or 144Hz
- Mixed movie, sport and streaming use in a living room
Skip if
- Shoppers who want a current model with the longest software support
- Anyone who needs HDR10+
- Bright rooms that need the highest brightness

What reviewers found
Summaries in our own words. Follow the link to read each review in full.
Found the C4 a winner in most areas, with excellent picture, gaming and features. It held back from the top spot for ordinary sound, a price above its performance, tough rivals from Samsung and Sony, and no HDR10+ or ATSC 3.0 tuner.
Read the originalDescribed the C4 as a large upgrade over the dull C3, with a brighter, sharper and more dynamic picture.
Read the originalMeasured about 1,150 nits peak on a 10% window and 13ms input lag in Game mode, and liked the premium design, game-settings tools and the tweaked webOS.

What owners are saying
From Reddit and forums, paraphrased with a link to the original discussion. Community reports are anecdotal.
An owner says their C4 has been left running around the clock as a sports TV for about a year without visible burn-in, and suggests a protection plan that covers burn-in for peace of mind.

Questions
Is the LG C4 still worth buying?
Only if you can find a new unit at a clear discount to the C5 or C6. Lab tests put its 65-inch peak brightness at roughly 1,050 to 1,150 nits, which was strong when it launched. LG's store listed every size as out of stock on the day this was checked.
What are the exact US model numbers?
OLED42C4PUA, OLED48C4PUA, OLED55C4PUA, OLED65C4PUA, OLED77C4PUA and OLED83C4PUA, all taken from LG's US product pages.
Do all C4 sizes have the same features?
Mostly. LG's tables list Brightness Booster for the 55-inch and larger sizes but not for the 42 and 48-inch, and the 42-inch has 2.0-channel speakers rather than 2.2.
Does the C4 support HDR10+ or DTS?
It does not list HDR10+. LG lists DTS:X as pass-through only, with no DTS decoder in its codec list.
How does the C4 compare for gaming?
Tom's Guide measured 9.2ms input lag with Boost on, and LG lists 4K 120Hz and VRR up to 144Hz on all four HDMI inputs.
