This is the third LG page on this site, and it opens like the other two: there is nothing here to disable over ADB. Both the OLED B5 and the 2025 UHD UA range run webOS 25, which is not Android. No USB debugging, no sideloading, no list of packages to go through.
What you can do is in the webOS guide, and the first job is switching off Live Plus, the content recognition that ships enabled.
One note on naming before we go on: LG's 2025 UHD range is the UA series.
UT sets are from 2024 and UR sets from 2023. If the model in front of you
starts with UT or UR, it is old stock.
The real question: how does a B5 differ from a C5?
It is the brand's most common buying doubt, and it is answered by putting LG's two tables side by side. Ten lines change.
The processor: "α8 AI Processor 4K Gen2" on the B5 against "α9 AI Processor 4K Gen8" on the C5. Upscaling drops with it, and so does tone mapping, which the C5 calls "OLED Dynamic Tone Mapping Pro" and the B5 lists without the "OLED" in front.
The refresh rate: both declare a 120 Hz panel, but the C5 says "120Hz Nativos (VRR 144Hz)" and the B5 just "120Hz Native", with "VRR (Variable Refresh Rate): Yes (Up to 120Hz)". There is no 144.
The sound: "20W" and "2.0 channel" on the B5 against "40W" and "2.2 Canales" on the C5. Half the watts and no subwoofer.
The eARC: and here is the detail almost nobody mentions. On the C5 and G5 the sheet says "eARC (HDMI 2)"; on the B5 it says "eARC (HDMI 3)". If you are coming from an older LG and you plug the soundbar in where you always did, you will get no sound.
Then three smaller cuts: two USB instead of three, HFR limited to "4K 120 fps (HDMI)" where the C5 says "(HDMI, RF, USB)", and the disappearance of the "Control por Voz sin Mando" field, voice control with no remote.
And where they are identical
In nearly everything else, and that deserves saying just as plainly. Both declare "4K OLED", "Dolby Vision / HDR10 / HLG", "4ea (supports 4K 120Hz, eARC, VRR, ALLM, QMS (4 port))", G-Sync and FreeSync, "Auto Calibration", AI Picture Pro, Wi-Fi 6, Bluetooth 5.3, the Magic Remote in the box, VESA 300 x 200 and webOS 25.
The 65-inch B5 measures "1449 x 832 x 45.9" millimetres and weighs "17.1" kilos; the C5, "1441 x 826 x 45,1" and "16,6". Half a millimetre and half a kilo.
What does change visibly is the stand: the C5 uses a 470 x 230 centre pedestal, the B5 a "1057 x 235" crossbar that needs a cabinet almost as wide as the set.
The B5's brightness, and where LG publishes it
Here is a curiosity. The B5 page carries no brightness figure at all. The only one LG publishes is buried in the C5's small print: "50% more brightness is obtained in 3% window size portions of the screen compared to LG OLED B5 models (900 Nits) in SDR".
So: 900 nits, measured in a 3% window and in SDR, against the C5's 1,500. That is the real panel difference, and it is what separates an entry OLED from a high-end one. Watching at night you barely notice; in a bright room you do.
The B5's four HDMI, with no bandwidth figure
On the C5, LG's FAQ closes the matter: "All HDMI ports support the full HDMI 2.1 bandwidth (48Gbps)".
That sentence is not on the B5 page, in English or in Spanish. Nor on the UA pages. The B5's four ports declare 4K at 120 Hz, VRR, ALLM and QMS, which is what a current console needs, but LG does not write the 48 Gbps figure here and I am not going to write it for them.
The UA range: what falls away below the QNED
The UA75 and UA73 declare "4K UHD", "Backlight Type: Direct" (direct-lit, curiously, where the QNED80A is edge-lit) "60Hz Native", "VRR: Yes (Up to 60Hz)" and "α7 AI Processor 4K Gen8".
HDR stops at "HDR10 / HLG": there is no Dolby Vision. And the sound is "20W" in "2.0 channel" with no Dolby Atmos, which the B5 does have.
Ports drop to "3ea (supports eARC, ALLM)", with "eARC (HDMI 2)". Three HDMI, one taken by the soundbar, two left.
But the cut you feel daily is another one: the remote field says "Standard Remote". The Magic Remote is not included. And without it there is no voice: recognition is listed as "Ready (requires Magic Remote)". Turned around, this is a television that arrives with no microphone in the box.
UA73 or UA75: the higher number buys you nothing
I laid the two 65-inch tables on top of each other expecting to find the difference. There are three, and all three favour the cheaper set.
The 65UA73006LA declares "Bluetooth Support: Yes (v 5.1)" and "USB Input: x2 (v 2.0)". The 65UA75006LA, "v 5.0" and "x1". An older Bluetooth and half the USB ports on the senior model.
The UA73 is also slimmer ("1446 x 831 x 59.8" against "1455 x 841 x 67.9") and lighter ("15.6" kilos against "16.5") and it takes VESA 400 x 400 instead of 300 x 200.
Panel, processor, HDR, ports, sound, Wi-Fi and system: identical. The UA74006LB is in turn identical to the UA75 except for "Auto Calibration", which only the UA75 declares, and AirPlay 2 against AirPlay.
Power
From the sheets regulated by EU Regulation 2019/2013. The 65-inch B5: class F at 91.8 W in SDR and class G at 167 W in HDR. The 48-inch: class G at 64.8 W. The 77-inch: 115 W and 215 W.
The 65UA75006LA: class F at 100 W in SDR and G at 152 W. The 65UA73006LA: 102 W and 135 W. Yes, the 65-inch UHD draws more in SDR than the OLED of the same size.
Standby is 0.5 W, and networked standby 2.0 W, on every one of them.
How long they will keep updating it
The three clocks from the earlier pages are still here. The UK page for the B5 and those for the 65-inch UA sets say the same thing: "The security update is supported until: 31/12/2029".
The Re:New programme keeps its small print (five years of webOS system renewals) along with the warning that accepting one "may cause the loss of certain features present in the previous version".
And the regulated sheet declares 8 years of software and firmware updates, spare parts and product support from the date the model leaves the market.
The microphone is not in the television
From the regulated sheet, on every model: "Voice recognition sensor available: No" and "Room presence sensor available: No". On the B5 the microphone lives in the Magic Remote; on the UA range there is no microphone anywhere unless you buy that remote separately.
How to tell whether this page is about your set
The European codes look like OLED65B56LA, 65UA75006LA and
65UA73006LA. What matters are the characters after the size: B5, or
UA73/UA74/UA75. They are on the sticker at the back and under
Settings → Support → TV Information. Within the B5, all five sizes carry
the same electronics: no surprises like the 43-inch QNED87A.
What can actually come off
The same as on any LG running webOS 25: Live Plus first, walked through step by step in the webOS guide; then personalised ads and recommendations, spread over several privacy screens; and last, the apps webOS lets you uninstall.
The gaps in this page
LG publishes no brightness figure in nits for the UA range, no dimming zone count, and no RAM or internal storage for any of these models. Nor does it give the HDMI bandwidth of the B5 or the UA, a figure it does write down for the C5.
