Xbox Making TV Screen go Crazy

So should I switch out my 26 inch LCD display that is HD but its really old. Probably from like late 2003 too. I mean I'm find with screen size and everything its just that I see SO many people going to TV's above 40 inches. Does it really make a difference
in your gaming? Bigger screen is better or smaller screen?

I heard that some people told me that the smaller screen you have its better. Is this true? Wow Its crazy all of you are like gaming on better TV's. I'm really jealous to be honest I used to game on this **** non hd TV then I got the LCD tv for my room.

Hey so.... after like 4 days of my tv working normally it started glitching out like crazy again. We've tried it on multiple tv's and have tried multiple HDMI cables but only one cable and tv worked. On the tv in my kitchen, there weren't any glitchy lines or anything but it would still black out every 2 seconds and it's so frustrating. We are going to bring the xbox in for a clean or repair... idk what to do anymore. I'm worried that my xbox is the problem and that it can't be fixed. As I'm typing this I'm in my room looking at my xbox home screen going black every 2 seconds and having glitchy lines go across the screen like mad.. Please help ;-;

I'm sorry but for anyone to think titanfall would be split screen is crazy even on my 55" tv it's sometimes tough to spot grunts and pilots, to think of that screen split is just a headache involving you squinting and sitting g really close to the tv

Does your TV have a power saving mode for the screen or does it have room environment mode?, that means the darker the room is the tv will make the screen go darker. Alot of the newer tv's have this and sometimes you don't notice so maybe check the tv maual
for this and if it's their disable those functions. I found this problem with my tv i have to disbale the environment feature to make the screen brighter and it makes i big difference.

Go to picture > screen adjustment > picture size > screen fit on the samsung tv. screen fit will make it look good on your screen.
