LG 75PK640S0UA 75" 4K UHD Commercial TV, webOS 25, Replaces 75UR640S9UD

The LG 75PK640S0UA is a 75-inch 4K commercial television built for businesses that need a large screen running all day. It replaces the earlier 75UR640S9UD and runs on webOS 25, so you can schedule content, lock the settings and manage it over the network without a separate media player.

75-inch 4K UHD Direct LED display

A 3840 x 2160 panel on a 75-inch screen keeps text sharp even when people read it from across a lobby or a classroom. Direct LED backlighting spreads light evenly behind the whole panel instead of only from the edges, which keeps brightness consistent from corner to corner during long hours of use.

• 3840 x 2160 (4K UHD) resolution
• Direct LED backlight, flat panel
• 300 nits brightness, 1200:1 contrast
• 60Hz refresh, 8ms response
• HDR10 Pro and HLG support
• K25Lp picture processor

webOS 25 with built-in content management

webOS runs on the screen itself, so simple signage and menu boards do not need an external player or PC. The Launcher Bar, web browser, IP streaming support and timer scheduling are built in, and the display can be controlled over the network or through RS-232C from an AV system.

Built-in tuners for live TV

Unlike a pure signage panel, this model has ATSC, NTSC and Clear QAM tuners built in. Connect an antenna or a hotel or office cable feed and it shows live channels with no set-top box. That makes it a fit for waiting rooms, break rooms, bars, gyms and hotel properties that need both TV and scheduled content on the same screen.

Full commercial connectivity

• 2 x HDMI
• 1 x USB Type-A
• RF In for antenna or cable
• RJ45 Gigabit LAN
• RS-232C In (3.5mm) for AV control systems
• IR Out (3.5mm)
• Optical Digital Audio Out
• External Speaker Out (3.5mm)
• Built-in Wi-Fi (802.11ac) and Bluetooth

Two 10W speakers are built in, so small rooms need no extra audio. For larger spaces, run the optical or external speaker output to a sound system.

Mounting and installation

The display uses a 300 x 300 mm VESA pattern. If you are replacing an older 75UR640S9UD, check your bracket — that model used 400 x 400 mm and your existing mount may not line up. A table stand is included for counter and desk placement.

3-year limited warranty

LG covers this display with a 3-year limited warranty, which is longer than the 1-year cover on consumer televisions and is what most business and education purchase rules require. Assembled in Mexico.

Frequently asked questions

Is this the same as the 75UR640S9UD?
No. The 75PK640S0UA is the replacement model. The panel size and resolution are the same, but the VESA pattern changed from 400 x 400 to 300 x 300, brightness is 300 nits instead of 330, and it runs webOS 25.

Can it show live TV channels?
Yes. ATSC, NTSC and Clear QAM tuners are built in. No cable box needed for a standard antenna or Clear QAM feed.

Can I run it 24 hours a day?
It is a commercial display built for extended daily operation in business settings. For true 24/7 continuous signage, ask us about LG's dedicated signage series instead.

Does it work in portrait?
Confirm with us before ordering. Portrait orientation was supported on the previous UR640S model and we are verifying it on the PK640S.

What size mount do I need?
300 x 300 mm VESA, rated for at least 52 lb.
