I have my pc downstairs with a 4k 55’ tv. Upstairs i have another of the same tv sitting right over the tv thats downstairs. Sometimes i want to play upstairs, as its pretty cold downstairs. I thought a long hdmi cable would do, but i cant just drill a hole in floor and stuff it through. Also, buying a streaming device is not the best option, as i have capped bandwidth. What suggestions do you have??
