The best Prime Day OLED TV deal: LG C5 vs. Samsung S90F

A lot of savvy shoppers save big-ticket purchases for major shopping events like Amazon Prime Day or Black Friday, and that's exactly what the Mashable shopping team recommends. These are the two best times of year to find deals on TVs, and this year's best Prime Day deals don't disappoint. Speaking of Prime Day 2026, two of the best OLED TVs in the world are down to their lowest-ever prices.

The Samsung S90F 65-inch OLED TV is marked down to $1,197.99, while the 65-inch LG C5 OLED has a Prime Day price of $1,199. With a price difference of just $2, which should you choose?

As Mashable's tech editor, I'm here to help you decide. I also have very good news: There are no wrong decisions here.

Why buy the Samsung S90F OLED TV during Prime Day

If money was no object, we'd certainly spring for Samsung's flagship OLED, the S95F, which features Art Mode and the same anti-glare technology that made The Frame Art TV from Samsung so famous. But for most people, money is most definitely an object. Hence, the S90F. While you lose out on these two critical features, these two TVs are otherwise extremely similar.

Technically, the S90F is a mid-range set, but is still has a high native refresh rate of 144Hz, a gorgeous 4K OLED display, and an AI processor for upscaling content. It also has a peak brightness of 1,600 nits, which is bright enough for virtually any indoor setting.

Plus, Samsung TVs have a reputation for lasting a long time, and the Samsung smart TV UX is pretty painless.

Why buy the LG C5 OLED TV during Prime Day?

While Samsung has caught up quite a bit in recent years, LG had the OLED TV market on lock for quite awhile. LG's famous C Series TVs have won tons of TV of the year awards, and you can always count on the new C Series release to be one of, if not the best, TV of the year. However, until we see the new LG C6 go on sale, a lot of TV reviewers are still recommending the 2025 C5 model, which already has a killer display and feature set.

Like the S90F, the LG C5 supports HDR10 and HLG, but unlike the Samsung, it does support Dolby Vision. Most reviewers agree that the Samsung is slightly brighter, though not noticeably so.

Overall, these TVs have remarkably similar specs, which probably explains the near-identical price tags.

My choice: Samsung by a hair

Overall, I can't say that one of these TV's is definitively better than the other. The choice ultimately comes down to which product ecosystem you prefer, and for my money, that's Samsung. For what it's worth, my colleagues at CNET recently named the Samsung S90F the best TV to buy in 2026, with LG as a close runner-up. (Disclosure: CNET and Mashable are both owned by the same parent company, Ziff Davis.)

Other sizes of these TVs are on sale for Prime Day 2026, but I think 65-inch, flat-screen TVs are the Platonic ideal for this product category. Like I said, there are no bad choices here:

• Samsung 65-inch S90F OLED 4K TV — $1,197.99 $1,697.99 (save $500)  ✅

• LG C5 Series 65-inch OLED 4K TV — $1,199.99 $1,396.99 (save $197)
