Have to be careful there or you might start a flame war between the "Spending any more than 3 cents for an HDMI cable is highway robbery, it's just zeros and ones!" crowd versus the "But premium cables actually are manufactured better and will avoid potential problems" folks.
Bottom line, buy pretty much any cable with the HDMI logo that explicitly states "High Speed."
Preferably get it from a recognizable brand rather than the absolute cheapest generic cable you can find. It doesn't have to be a super premium cable and doesn't have to cost a lot, unless your needs are exceptional (for example a very long run, a high EMI/RFI/humidity/sulfur environment, very frequent plugging/unplugging/flexing, and/or marginal devices on one end or the other) or if you care a lot about aesthetics and theoretically better reliability and are willing to pay an extra premium for it. Some people are, and that's fine, it's their choice.
I have also actually encountered problems caused by damaged, defective, or non-high speed rated cables that cause dropouts, flickering, "sparkles" or no signal at all. So it's always a good idea to try a new cable to eliminate that factor first and verify it's actually a device problem.
