A decade ago, if you wanted to buy a big-screen TV (basically anything over 65 inches), you’d expect to pay at least $5,000. If you were shopping at the more premium end of the market, that price could go well higher.

Fast forward to the present, and 65-inch TVs have become the standard. 75-inch TVs have become widely popular, too. And naturally, the price of these big-screen TVs has gone way, way down.

Depending on the make and model, you can expect to spend between $600 and $1,200 on most 65-inch TVs today. For a larger 75-inch TV, you can expect to spend between $800 and $1,500 on a similar model.

That said, if you know where to look (and when to shop), you can get a significantly better deal on a big-screen TV. In fact, the deal might seem too good to be true … but it’s not.

Take TCL’s Q77K series as an example. Released in 2025, it’s one of the brand’s most entry-level smart TVs, but it’s packed with features that most modern TV shoppers want.

The 4K QLED TV features a high contrast HVA panel, packs a 144Hz refresh rate, and supports most of today’s popular HDR technologies (including HDR PRO+ Dolby Vision, HDR10+, HDR10 and HLG).

Additionally, it comes baked with a Google TV smart operating system to quickly access all your favorite streaming services.

TCL sells its Q77K series as a Costco-exclusive in North America. It comes in multiple different sizes, ranging from 55 inches to 98 inches. (Yes, TVs get quite big in 2026.)

For those particularly looking for a 75-inch TV, Costco is running a pretty incredible deal on the 75-inch model of TCL’s Q77K series right now.

Availability and pricing

The TCL 75Q77K, or the 75-inch Q77K series, normally sells for $749. This is pretty cheap for a 75-inch TV as it stands. But right now, Costco is discounting the TV by another $250.

That’s right, you can score this massive 75-inch TV for less than $500.

The deal is live now. It runs through March 29th.
