I'm looking to buy a DisplayPort cable that's over 5 meters for my 240Hz ultrawide monitor, and I'm a bit confused. I read that going for a cheap $25 cable might lead to issues like black screens, and I've seen recommendations for $130 cables. Should I invest in the expensive one, or would the cheaper option work fine?

Honestly, I wouldn't trust a $25 DisplayPort cable for that length. For high refresh rates over long distances, you really should consider a fiber optic DisplayPort cable, even though they're pricier.
You could give the $25 one a shot. If it doesn’t work out, just return it and find something better. Just make sure to check out the reviews first!
Keep in mind that you usually don’t get DisplayPort cables longer than 3 meters without some potential issues. Beyond that, it really depends on whether you have an active cable, and even then, it's a bit of a gamble depending on the monitor. Reputable vendors might try to mislead with their certifications, so stay cautious with brands. If you have a 3440x1440 240Hz monitor, you might be fine; however, for 4K 240Hz, it could get tricky.

I saw that too! The reviews for the cheap one are really glowing, but the $130 cable has mixed reviews (2.5 stars). How do I know if it works well?
