Need HDMI extender, I went to: Roku | HDMI® extender; but it says the SN number is incorrect that i enter, but it is correct.

First, the HDMI extender is only available for the Roku Stick, not the other players. In fact the extender cable will not work on a regular player because the connectors on the end need to both be male for the regular player and the extender has a male and female connector.

If your Roku is a Stick, then you've likely made an error in the serial number. Sometimes the number 0 is confused with the letter O, and the number 5 with the letter S. The best way to ensure you have it correct is to copy your serial number from your user page (https://my.roku.com) and paste it into the extender request page.

There's nothing special about the Roku HDMI extension, it's just a short (4 inches or so) HDMI cord with an HDMI plug at one end and an HDMI socket at the other. I use a non-Roku one several feet long to locate my Streaming Stick in an equipment closet on the other side of the wall from my TV. You may be able to find an HDMI extension locally and not have to wait for someone to ship it to you.

Alternately, you can make your own HDMI extension by  connecting a standard male-to-male HDMI cord to a female-female HDMI connecter.

I travel with this combination. Not all hotel TVs have a convenient place to plug in a Roku Stick, so having the cable and a female-female adapter gives me flexibility.

Roku should include the free HDMI extender in the packaging for the Roku Sticks since it's well known that using the extender can improve performance. There is plenty of space to include it in the box if it were slightly redesigned to accommodate it.

If you get a Fire TV Stick it will come with an HDMI extender in the box, yet Roku makes you jump through hoops in order to get one. You must type in your serial number then wait several days for it to arrive in the mail, all of that is ridiculous and unnecessary if they just included it.

Also your Roku Stick has two serial numbers, there is a physical one printed on the box and on the back of the Roku Stick itself, then another digital serial number that you can view on your TV screen when you go to your system settings on the Roku. I believe when you go to your Roku account and find your device it displays the same digital serial number there. My guess is you entered the wrong one and that's why it won't accept.

When entering your serial number to order the free HDMI extender you need to make sure to enter the serial number that is printed on the actual Roku box and Roku Stick, do not enter the digital serial number because it won't accept that. I had this same problem when I entered the wrong digital serial number and it told me it was a wrong number.

This is another thing that Roku completely fails to make clear when asking for your serial number, this whole situation with the HDMI extenders from Roku is a joke! Roku, just put the extender in the box along with everything else and end all this nonsense!
