LG C4 OLED evo 42-Inch TV vs Roku Pro Series OLED

The LG C4 is the better pick for most people deciding between these two. It has four HDMI 2.1 ports, G-Sync and FreeSync Premium, Dolby Vision and near-perfect blacks from self-lit pixels, and reviewers consistently praise its picture and easy setup. The Roku Pro Series is a QLED Mini-LED set with a simpler Roku interface, side-firing speakers and hands-free voice support, but it has only two HDMI ports and no Dolby Vision on the 42-inch class. Choose the LG for gaming and dark-room movies; choose the Roku for a bright room and the easiest smart TV interface.

  • Choose the LG C4 if you game on a console or PC, watch movies in a dark room, or want four HDMI 2.1 ports and G-Sync support.
  • Choose the Roku Pro Series if you want the simplest smart TV interface, hands-free voice control, or a larger screen for a bright living room.

Reviewers rate the C4 highly, calling it an excellent TV with a very clear picture and simple plug-and-play setup. Packaging and wall-mounting drew praise, and one owner reported no eye strain using it as a computer monitor. Complaints were few: the Magic Remote's roving cursor is hard for elderly users, and one unit reportedly showed burn-in.

Questions and answers

Which is better for gaming, the LG C4 or the Roku Pro Series?
The LG C4. It has four HDMI 2.1 ports, G-Sync certification, FreeSync Premium and a 120 Hz panel, so you can connect a console and a PC without a switcher. The Roku Pro Series also does 120 Hz with VRR and FreeSync Premium Pro, but two HDMI ports limit you.
Which has better picture quality in a dark room?
The LG C4. OLED pixels switch off individually, so blacks are truly black and contrast is near infinite. The Roku Pro Series is a Mini-LED QLED set, which gets bright but shows some blooming around bright objects on dark backgrounds.
Is the Roku Pro Series easier to use?
Yes for most people. Roku OS has a simple home screen and a straightforward remote, and the set supports Google Assistant and Alexa. LG's webOS is also well organized, but the Magic Remote's pointer takes getting used to, and some older users find it hard.
Which lasts longer, OLED or QLED?
Both should last many years, but OLED can develop burn-in from static logos, tickers or game HUDs left on for long stretches. QLED has no burn-in risk. LG covers the C4 panel for burn-in for five years in the US, and reviewers report only rare burn-in cases.
Should I step up to the Roku Pro Series for a bigger screen?
If you want 55 inches or larger, the Roku Pro Series is the only option here, since this LG C4 listing is 42 inches. If 42 inches fits your room, the LG gives you better contrast and more gaming ports for the same class of TV.
Does the LG C4 support Dolby Vision and Dolby Atmos?
Yes. The C4 supports Dolby Vision, HDR10 and HLG, plus Dolby Atmos through its speakers. The Roku Pro Series supports Dolby Vision IQ, HDR10+ and Dolby Atmos, so both cover the main formats.
