TV Answer Man, do you know if Sunday’s NASCAR race, the Straight Talk Wireless 400 will be in 4K? – Gene, Pittsburgh. 

Gene, the NASCAR Straight Talk Wireless 400 today, March 23 2025, will be available in upscaled 4K. The race, which will be broadcast by Fox at 3 p.m. today, will take place at the Homestead-Miami Speedway in Homestead, Florida. Fs1 will simulcast the race in High-Definition.

How Can You Watch Fox In 4K?

Fox’s 4K live sports broadcasts can be seen in 4K on the Fox Sports app by logging in with your TV Everywhere user name and password from your pay TV provider. (Note that the Fox Now app is no longer available.)

The pay TV services that normally Fox games in 4K on special 4K channels are DIRECTV, Dish, Sling TV, Comcast, Verizon, Optimum, DIRECTV Stream, YouTube TV, and FuboTV. (In FuboTV markets where the Fox affiliate is provided with your programming package.) Check your on-screen guide for more details.

What Does Upscaled Fox 4K Look Like?

Fox’s 4K live sports broadcasts are upscaled from 1080p HDR (High Dynamic Range). Upscaling is the process when one video format is converted to another. Fox takes the 1080p HDR signal and converts it to a 4K format. Upscaling 4K is not considered as good as native 4K, but the inclusion of HDR can offer heightened colors and vividness. ESPN also upscaled its 4K broadcasts from a 1080p HD signal.

Is It Worth Watching Fox In Upscaled 4K?

Yes. From personal experience, I can assure you the picture is usually better. The high-def image from a Fox affiliate sometimes lacks detail and makes you wonder if it’s actually in high-def. However, the 4K image removes the blurriness and adds a realistic feel to the picture.

Gene, hope that answers your question. Happy viewing and stay safe!
