Non-Compatible HDMI Tv's

[Phase202]

Just recently purchased a 40" Dynex TV (which is Best Buy's brand) that came with 4 HDMI ports. None of them have fully worked with my HDMI ( full mirroring or stock). I Have now tried two different cables to no avail. I was ONCE able to get video, but no sound. Took it to Best Buy, had them try it out, worked perfectly. Went home for 2nd attempt, FAIL . Bought another cable from Monoprice (thanks to you PPCG peeps), bought some compressed non moisture dust remover and tried that one out, 2ND FAIL . Went back to Best Buy today and and tried my new cord on 4 other different TV's (Sharp, Sony, Toshiba, Insignia). Worked perfectly with all except the Insignia.

I Post this to say, in my recent trials, the HDMI is not Compatible with either Dynex or Insignia Brands. Just a warning for people having HDMI issues . Let me know if anyone else has other results.
