hi guys, i have a HDTV with 2 HDMI ports, since i have 3 devices that require connected to TV, i hv purchase this HDMI switch
http://www.lazada.com.my/3-port-1080p-vide...vd-1984862.html

here is the current setup:

TV port 1------- HDMI switch ( 3 in , 1 out) ===== ( PS4, hyyptv, set-up-box)
all using HDMI cable less than 2meters.

but right now i hv problem with PS4, its only work for 1st time turn on, then after than, my HDMI switch LED light will blinking. googled and some people said PS4 HDMI connection is quite low powered, thus if connect to HDMI switch with no external power, its not enough power to transmit. not sure if this correct. but if i connect directly to TV, no problem.

then i changed to this setup:

TV port 1------- HDMI switch ( 3 in , 1 out)====== ( hyyptv, set-up-box)
port 2--------- PS4
all using HDMI cable less than 2meters.

TV to PS4, no problem so far. but i have problem with set-up-box, the display show lil bit bigger , thus i need to setup the display position manually, i mean the display is over the edge of the screen, so i need to configure it smaller so that its fit to the screen. i thot HDMI no need this anymore since its can automatically calibrate itself?
another problem i have is, for set-up-box, i see the screen brightness quite dark than normal.

i tried change the cable, seem like each cable diff result, some were ok, some got this dark brightness/over-the-edge- display problem.

test the cable connect directly to TV, all seem ok except new cable i just bought from Giant, i didnt test it yet.
any 1 got this problem with HDMI switch ?
