VHBW Replacment for LG Monitor Power Cord 19V DC Power Supply for LG Electronics 27" 24" 23" 22" 20" 19" LCD LED HD TV Monitor Widescreen Power Adapter Cord

Why I reached for this adapter

A missing or damaged power brick can sideline a perfectly good monitor, so I keep a few reliable replacements in my kit. I added the VHBW adapter to cover LG’s 19V monitors that use the 6.5 × 4.4 mm barrel connector with a center pin. Over several weeks, I used it on a couple of LG displays at my desk and a wall-mounted setup in a small studio, paying attention to the basics that matter with power gear: fit, stability, heat, noise, and cable reach.

What it is, in plain terms

This is a 19V DC, 2.1A (40W) external power adapter designed for LG monitors and some smaller LG TVs that use a barrel plug with an inner pin. It accepts 100–240V AC input (so it works worldwide) and claims the usual protection circuitry: over-voltage, over-current, over-load, and short-circuit. The cable length is a practical 9.8 feet end-to-end.

The simplified takeaway: if your LG monitor label reads “DC 19V” and the original brick used a 6.5 × 4.4 mm connector with a center pin, this adapter is intended to be a drop-in replacement.

Setup and compatibility checks

Power adapters aren’t universal. Before connecting anything, I always run through a quick checklist:

• Match voltage exactly: 19V on the monitor and 19V on the adapter.
• Current must meet or exceed what the display asks for. This brick supplies up to 2.1A (40W). If your monitor label requires, say, 19V 1.5A or 19V 2.0A, you’re clear. If it needs 2.5A or more, you’ll want a higher-wattage unit.
• Confirm the connector: 6.5 mm outer diameter, 4.4 mm inner diameter, with a center pin. It needs to insert snugly with no wobble.

With those boxes checked, setup is plug-and-play. I connected it to two LG monitors that specify 19V at under 40W and use the center-pin barrel. The plug seated securely with the right friction, and the monitors powered up immediately.

A quick note because it comes up often: this is not for Peloton bikes or for larger smart TVs that use higher-wattage supplies or different plug sizes. If you’re replacing a TV power brick, double-check the current requirement—many televisions exceed 40W.

Day-to-day performance

Once connected, I care about three things: does the display power up consistently, does it stay stable, and does the adapter behave itself.

• Power stability: Both monitors woke promptly from cold start and from sleep without hiccups. I saw no flicker or dropout while switching inputs or changing refresh rates.
• Electrical noise: I didn’t hear coil whine from the brick, and the displays behaved normally—no on-screen artifacts or menu glitches that can sometimes hint at dirty power.
• Heat: Under typical office use (web, office apps, sustained brightness at ~60–70%), the brick warmed up but stayed comfortably in the “warm touch” zone. Nothing unusual for a 40W-class supply.

In short, it performed like an OEM brick should: invisible in daily use.

Build quality and design

The enclosure is light and compact for its wattage class. The plastic shell doesn’t flex under a squeeze, and the strain relief on both DC and AC ends is decent. The barrel plug itself has clean machining and a firm spring contact that feels confidence-inspiring when you seat it.

This isn’t a ruggedized unit, and I wouldn’t subject it to frequent travel abuse without a bit of care, but for a desktop or wall-mounted install it’s more than adequate. It balanced well on a power strip without hanging awkwardly or tugging on the cable.

Cable length and mounting flexibility

The roughly 9.8-foot total reach is the quiet hero here. I used the adapter on a wall-mounted monitor where the original cord came up short; the extra length let me route along a channel and reach an outlet lower on the wall without adding an extension. At a sit–stand desk, that extra slack prevented the brick from fighting the lift mechanism. If cable length has ever forced you into annoying power strip placements, this is an easy quality-of-life upgrade.

Safety and reliability

The adapter is marked CE/FCC/RoHS and advertises the standard protection suite (OVP, OCP, OLP, SCP). I didn’t trip any protection during use, but it’s the sort of circuitry you hope never to notice. More practically, the unit behaved predictably on surge-protected strips and on a UPS without false trips. There was no excessive heat even after hours of sustained use, and no audible clicking or cycling.

One subtle positive: the center pin and barrel tolerances feel right. Poorly spec’d connectors can arc during insertion or make intermittent contact; I didn’t run into that here.

What to watch out for

No power adapter is truly universal, and there are a few situations where this one won’t be the right choice:

• Higher-wattage displays: Some ultrawides and larger LG screens ask for more than 40W (for example, 19V at 2.5A or 3.4A). Undersupplying current can cause startup failures or intermittent shutdowns. Check the rating plate on the monitor first.
• Different connector sizes: LG has used multiple barrel sizes across models. If your original plug is 5.5 × 2.1 mm or 5.5 × 2.5 mm (no inner pin), this adapter won’t fit.
• TVs vs. monitors: A number of LG TVs use 19V but at much higher amperage; others use 12V or 24V. Don’t assume interchangeability just because the plug looks similar.
• Specialty gear: This isn’t intended for bikes, docks, or laptops that happen to use 19V but with different wiring or power negotiation.

If you’re unsure, match the three things—voltage (19V), current (≤2.1A required), and the 6.5 × 4.4 mm center-pin connector—before buying.

Practical tips from use

• Check the label on your original adapter or the back of the monitor. You’re looking for “DC 19V” and a current figure equal to or less than 2.1A.
• If the original brick is missing, a quick search of your exact model plus “power adapter” often turns up the official rating; cross-reference a couple of sources to be safe.
• For older LG models, shine a light into the DC jack—you can usually see the center pin that this adapter mates with.
• If you’re mounting the brick under a desk, give it some breathing room. Even efficient 40W supplies need airflow to avoid heat buildup.

Value and warranty

Compared to OEM bricks, the VHBW adapter hits a friendlier price point without obvious compromises in everyday use. The one-year exchange promise is basic but reasonable for a commodity power supply. Given the build, protections, and cable length, it’s a sensible buy if it meets your spec.

Who this is for

• Owners of LG 19V monitors that require 40W or less and use the 6.5 × 4.4 mm center-pin connector.
• Anyone who needs a little extra cable reach for wall mounts or sit–stand desks.
• IT folks who want a reliable, labeled spare in the drawer for common LG display models.

Who should look elsewhere:

• Users with higher-wattage ultrawides or TVs that exceed 40W.
• Setups using different barrel sizes, USB-C power delivery, or proprietary DC tips.

Recommendation

I recommend this VHBW adapter for LG monitors that match its 19V, ≤40W, 6.5 × 4.4 mm center-pin spec. In my testing it delivered stable power, stayed quiet and reasonably cool, and the longer cable made placement easier for both wall and desk setups. The safety features and worldwide voltage support add confidence, and the price undercuts many OEM replacements without the usual fit-and-finish trade-offs. Just do the quick compatibility check up front—voltage, current, connector—and it’s an easy, dependable fix for a lost or failing LG power brick.
