I see October 1, 2018 at https://www.samsung.com/us/support/owners/product/2018-full-hd-led-tv-m5300
I didn't find a n5300 so if there is any doubt about this, call the seller and maker to confirm.
hello to all
so , I just purchased a new n5300 samsung full hd tv .
when I first connected the cable box through hdmi cable it gave "mode not supported" message .
I tried the hdmi cable and the cable box and they worked fine on another tv.
I went to the cable box settings and changed tv system to "NTSC" .hdmi mode to "480p60" and it worked but in the low quality . when I change back to 1080 or 720 it does not work . it either show the " mode not supported" message again or keeps flickering .
it works fine when I connect my laptop through the hdmi cable . and it worked fine when I used the built-in receiver .
I saw some talking about entering the TV service menu to change resolutions and so but none of the ways they mentioned worked with me.
