A 48-inch TV that RTINGS reviewed as a monitor is easy to misread as a TV review. This LG OLED48C6PUA review leans on that write-up, in which RTINGS reviewed the 48-inch LG C6 (its model table lists it as OLED48C6PUA) using settings chosen to better represent PC-monitor use.

No testing of ours went into this page. Statements about the test and its results come from RTINGS, while the limits described in the section on what this test doesn’t tell a TV buyer are ours, and we quote no scores or measurements.

RTINGS rates the screen very highly for PC gaming, and it lists VRR flicker and the lack of DisplayPort as its two Cons. The sections that follow cover how the 48-inch differs from other C6 sizes, what that testing covers, and what it leaves open.

LG C6 48-Inch Review: How This Size Differs From Other C6 Models

The Panel

RTINGS’ model table lists the 48-inch with a Tandem OLED panel and a Brightness Booster, and it shows the 42-inch, 55-inch and 65-inch C6 models with WOLED panels.

According to RTINGS, the 48-inch is the only C6 size with a Tandem panel, similar to the one in the C6H, a variant the table lists at 77 and 83 inches. RTINGS also says that Tandem panel is more colorful than the panels in the other C6 sizes.

Why It Matters for Other C6 Coverage

Per RTINGS, its results for this TV aren’t comparable to its TV results for the 65-inch C6 and the 77-inch C6H, because monitors and TVs are tested in different ways. Those TV pages therefore shouldn’t be used to judge this size.

What RTINGS Actually Tested

A TV Reviewed on the Monitor Side

RTINGS titles it the LG C6 48″ OLED Monitor Review and describes the set as a 48-inch TV that’s popular to use as a monitor. It says it used different settings from those in its TV tests, chosen to represent use with a PC.

LG OLED48C6PUA Review: Which Model Code RTINGS Reviewed

RTINGS says it bought and tested the 48-inch LG C6, and that its results are valid only for that size. Its model table lists the 48-inch as OLED48C6PUA and adds that full model codes vary between regions and retailers.

The part of the page we have doesn’t name the code of the unit it tested, so it’s worth matching the size and checking the code on any listing you’re considering.

What RTINGS Liked About It

Picture

RTINGS reports deep blacks that hold up in any environment, bright highlights in HDR, and a wide range of vivid colors. Those findings come from RTINGS’ PC-use settings.

Gaming

For PC gaming, RTINGS’ verdict is strongly positive. It points to smooth output at 165Hz, a very fast response time with minimal blur, low input lag, and a large 48-inch screen it calls immersive.

The review lists 165Hz as available in the TV’s Game Optimizer mode, alongside FreeSync Premium, G-SYNC compatibility and HDMI 2.1 bandwidth.

Trade-Offs to Weigh

VRR Flicker

RTINGS describes the VRR flicker as noticeable and says it could be distracting if your PC can’t hold a steady frame rate. It lists the flicker among its two Cons, so it’s the first item to set against the praise above.

No DisplayPort

RTINGS says the TV has HDMI 2.1 bandwidth but, unlike modern monitors, no DisplayPort inputs. That matters if your desk setup depends on DisplayPort.

Text Sharpness and Desk Hardware

The review says low pixel density makes some in-game text look blurry. It also notes that, as a TV, it lacks features most monitors have, such as an ergonomic stand or a KVM switch.

What This Test Doesn’t Tell a TV Buyer

Monitor Settings, Not TV Settings

RTINGS used different settings here than in its TV tests and says the two sets of results aren’t comparable. RTINGS’ settings were chosen to represent PC use, so for couch viewing of broadcasts, sports or streaming this page has nothing to go on.

One Size, One Source

The review covers the 48-inch only, and RTINGS’ own table shows other C6 sizes with different panels. This article rests on RTINGS’ written summary alone, with no LG documentation and no testing of our own.

Questions to Settle Elsewhere

Because we quote no scores or measurements and have no second source, this page can’t say how the TV sounds, how it looks in TV mode, or how it suits living-room viewing. Those need other evidence before you decide.

The Good, the Bad, and the Ugly

Pros

• ✅ Deep blacks — RTINGS says they hold up in any environment.
• ✅ Bright HDR highlights and vivid colors — a wide range of color, per RTINGS.
• ✅ Sharp motion and low input lag — RTINGS lists both for PC gaming, with the low lag holding at 165Hz in any mode.
• ✅ 165Hz with variable refresh — FreeSync Premium and G-SYNC compatibility are both listed.

Cons

• ❌ Distracting VRR flicker — RTINGS lists it among its two Cons.
• ❌ No DisplayPort inputs — RTINGS lists the lack of them as a Con.

The Ugly

The praise and the flicker point at the same use: a buyer whose PC can’t hold a steady frame rate has to weigh the two against each other.

A second limit is the evidence itself: with RTINGS’ PC-use settings, a buyer who wants TV-mode results has less to go on than the headline praise suggests.

Who Should Buy This — and Who Shouldn’t

Buy This If

This is a fit for PC players who want a big 48-inch OLED to game on, can live without DisplayPort, and can tolerate the VRR flicker RTINGS describes. Think of it as a review written for PC use that happens to be about a TV.

Skip This If

Skip it if your PC needs a DisplayPort connection, if flicker with variable refresh would bother you, or if you want TV-test results.

Final Verdict

Where the LG C6 48-Inch Fits

The case for this TV rests on PC gaming, with the flicker and the missing DisplayPort as the offsets. This LG OLED48C6PUA review can’t stretch that to TV-mode use, and the size and model code on your listing still need checking.
