I'd say it's definitely a buy at this price especially with the added warranty through Costco. The 83" B is almost identical to the 83" C (same processor), it's just not as bright (except in game mode for some reason). I have this tv in my basement and it is plenty bright for me. Unless they just have a ton of stock, I can't imagine the price getting lower especially with the whole tariff uncertainty. If you're in the market for a large OLED, I'd buy this without hesitation.

Some references:
RTings: https://www.rtings.com/tv/reviews/lg/b4-oled
"The 83-inch model shares a lot of similarities with the LG C4 OLED. It uses LG's Alpha 9 AI Processor Gen7, supports a 144Hz refresh rate, has three USB ports, and has a 2.2 channel speaker system, all of which are the same as the C4. Due to these shared features, we expect the 83-inch model to perform more in line with the C4. However, it doesn't have LG's Brightness Booster technology like the C4 does, so it isn't as bright overall."

Video comparison: https://youtu.be/3ew4vXcmDgU?si=czjkuzphz7lFUKmg

Edit: it's part of the buy more save more promo, so you can get a pretty awesome deal by combining it with a Gladiator rack for another $100. https://www.costco.com/.product.1...ue&nf=true
After researching to the point of madness, I purchased this from Costco 3 weeks ago. When you buy the B4 83", you are essentially buying a C4 83". It has all the same internal components as the C4 in this size. You will be amazed if never owning an OLED TV. If you are on the fence, just do it.

Is the 83B4 an upgrade over the 83C1? https://www.rtings.com/tv/tools/c...9540/21421
Not a fair comparison. The B4 review uses Rtings' latest, more strict, testing method (v2.0), while the C1 review uses the prior testing method (v1.11).

The relevant portion of the comparison are the brightness numbers:

Hallway Lights (~1950 cd/m²)

647 cd/m²
639 cd/m²
Yellow Skyscraper (~700 cd/m²)

467 cd/m²
369 cd/m²
Landscape Pool (~300 cd/m²)

258 cd/m²
142 cd/m²
Peak 2% Window

685 cd/m²
751 cd/m²
Peak 10% Window

675 cd/m²
747 cd/m²
Peak 25% Window

509 cd/m²
412 cd/m²
Peak 50% Window

328 cd/m²
277 cd/m²
Peak 100% Window

147 cd/m²
131 cd/m²
Sustained 2% Window

678 cd/m²
729 cd/m²
Sustained 10% Window

666 cd/m²
725 cd/m²
Sustained 25% Window

501 cd/m²
392 cd/m²
Sustained 50% Window

326 cd/m²
263 cd/m²
Sustained 100% Window

144 cd/m²
125 cd/m²

They are similar - the C1 wins in specular highlights, while the B4 wins in sustained 25% window and larger due to less aggressive ABL.

This reflects positively on the B4 because the C1 is a higher tier at a higher price point. Still, it looks like changing from C1 to B4 is a side-grade.

They aren't comparable how you are trying to compare them, not just due to the different test benches, but also due to the fact that the 83" B4 is essentially a reskinned C4 (only the 83" size is like that) makes it even less so.

It will be a bigger upgrade than it appears on paper, however having owned quite a few OLEDs imo most people would only notice a big difference aka upgrade when moving at least 5 gens up with the B and C lines.

I've been on the fence for the C4 for a long time. The picture is just superb. I reckon, I can expect the same from this B4, after all the posts above.

One quick question for the TV experts. Will this TV perform well, in a well lit room, with high windows, and the occasion direct sunlight on the TV?

My opinion is that no OLED will perform well with direct sunlight shining right on it. As long as that is during times you don't watch a ton of TV, it will prob be fine. This is prob in the top 5 OLED sets that would be best for your situation though. The only thing this doesn't have compared to the C4 is the brightness enhancer, which admittedly would be a plus for your situation. All OLEDs perform best in a dim room, unfortunate facts.

Thanks. Good to know. There is about 1-2hours of direct sunlight, and we rarely use the TV during those times. So I think its OK. I pulled the trigger. Its B4 that performs like a C4, and I know I like the C4. And its Costco! So.... all good. This is a great deal.

TV gurus - is this a good one? $2k for 83" OLED seems good, but i don't track OLED prices
For almost everybody - YES.

For those looking for every specific things from a TV - NO

It is that 95/5 lifestyle. The B series has jumped up incredibly but it's also just because OLEDs themselves are getting stagnant. A B2 ain't the same as a B4. Have fun with this!

OLEDs are not good fit for direct sunlight. Not only ruins the picture quality in the moment, but also degrades the panel faster.

You should look for a Mini LED, which excels in bright rooms, can handle direct sunlight better, and no risk of burn in.

The TCL QM8 85 inch on Amazon for $1800 is a great option for your use case.

Side note, I don't think the C4 is worth it over this 83 B4 with the same internals.

I saw the regular B4, C4, and G4 side by side at Best Buy. B4 & C4 are so close that most people would be better off saving their money and get the B4, or spend the extra on the G4 for a more substantial and noticeable upgrade. And for any other size besides 83, the Samsung S90D is another great option with QD-OLED (the 83 S90D is WOLED and inferior to LG)

Thanks for the commentary. Yeah my last upgrade was 65B6 to 83C1. 65B6 is sitting in my basement.

I might just hold off another year.

FYI: The extended warranty/protection plan is a joke. For about two months now I've been trying to get my 65" Samsung S95B (from Costco) repaired. Repair turned into a failed repair, turned into a "replacement", but the only replacement option I've been given is a $350 Hisense QLED. When I asked for a review it's "we'll contact you within about 24hr." They didn't. When I called again they tried to tell me that the Hisense was a "newer, upgraded" version of my Samsung. I told them that's patently false, they need to give me a more comparable OLED option. Now I'll wait another "1-2 days", probably without any follow up. Tempted to grab this and just unload whatever nonsense they end up giving me but hesitant knowing the extended warranty is pretty much pointless
From what I remember on another post long ago, this warranty company requires you to continuously push them for a proper equivalent replacement. They will always low-ball you with a crappy replacement in the hopes that you accept it. Don't give in, and keep pushing. It's a crappy process but as long as you are persistent you'll eventually get what you want (at least, I hope so!).

Imo the screen is way to big for competitive gaming where input lag would really be an issue, but for a TV it is great.
