I installed a 43 inch 4k LG smart TV along with 2 regular 32 inch LG smart TV's in a motorhome. Main purpose was tv upgrades and best picture available when watching satellite. So my tvs all feed off of an older 4 outputs x 1 input. My HDMI cables are 10 meters long. Everything looks great on TV's from satellite except the picture in the 43 inch 4k HDMI input. It's fuzzy no matter what I do. Any fix for it?

First swap around some of the cables so you can test with a known working cable.

See if the fuzziness follows the cable or stays with the 43" TV.

And try swapping ports on the splitter.

If you have an unused splitter port purchase install a terminator cap - not the same as the usual dust cover caps often provided.

You can usually purchase smaller packs at big box stores: Home Depot, Best Buy, Walmart....


Then consider that splitter itself may have a problem. Try another splitter - even a 2 or 3 port to test.

Splitting a signal does degrade its strength: some devices are more sensitive to (or maybe more...

Splitting a signal does degrade its strength: some devices are more sensitive to (or maybe more tolerant of) than others to such degradation.

Overall, the hope is to find the problem anywhere else but in the 43" TV.

Unfortunately a life on the road may be just too much vibration and something inside the 43" is not holding up.
