2 of 4 customers found the following review helpful: Don't buy these, 2008-05-16 These cables work well with 720P or below, but they don't work at all with cable boxes with true 1080P or with Blu-Ray at full resolution. Sorry, price and quality do matter. I bought 3 of these and none worked, but one $39 name brand cable from Target cured all of my Blu-Ray problems.
