Laptop HDMI conection to  3 TV's

I have a problem with a HDMI connection to 3 TV’s.
I have installed 2 Cat6 cables of about 130 to 150 feet to each TV.
I installed a HDMI converter from HDMI to 2 Cat6 to each TV and connected to a 1 to 4 splitter connected to a laptop.
The laptop is setup to have the HDMI as an extended Monitor.
The problem is that the TV’s blinks on and off every 5 to 10 minutes not all at once, one blinks more frequent than the others.
If I connect a different laptop it does not blink. Both laptop OS is Window 7

My question is, can the HDMI port on laptops vary output capacity or does the extended monitor of the HDMI configuration be configured differently.

Is the splitter powered? I assume it is not, when you describe you get different results with 2 different laptops.

When 'projecting' over long distance, you should think of equipment that is capable of doing so, you got the CAT6 cabling (should suffice) but a splitter like this one may improve your results:

(both claim to go up to 200ft - 1080i / 110ft - 1080p)

Thanks for the info,
is it not possible that the HDMI port have different output capacity on different laptops.

How would it work well on one laptop not another.

Yes this is possible, cable quality will be a factor as well.

You did not answer my question whether your splitter is powered or not. Is it?

Possible, sure.

>> Yes the spliter is powered.
What brand/type of splitter do you have and what is your resolution (1080i/p 720)?

it may a have been a combination of a few thing, i replaced 2 of the 3 HDMI converters to a single port cat5/cat6, i replaced the HDNI spliter and changed the laptop resolution to 1280 x 720.

Thank You
