HDTV running low resolution? Is it bad?

deep_27 · 15-04-2009, 09:07

Hello fellow DS'ers!

Im in a bit of a panic after a guy at work told me this so I thought id ask it here to confirm..

I have a computer attached to my main LCD TV which I use occasionally for work as its rather convenient, however I am running it on a screen resolution much lower than the HD (1920 X 1080) resolution, I am actually running it at 1280 X 1024 because its easier on my eyes.

What I want to know is; does running my computer like this on my TV do it no good? I have been told that I should be running it at the full HD resolution otherwise I could damage it.

Have you ever watched standard definition (i.e. Freeview, a DVD, Sky SD, a video) on your television. They are all transmitted at a much lower resolution than your computer output and they haven't damaged your screen have they?

Make sure you smack your workmate firmly around the head as you tell him he is an arsehole.

My car can manage 125 mph if I really put my foot to the floor. But I normally drive at no more than 90 even on the motorway, and to my knowledge I haven't damaged my car by doing this.

He's talking complete rubbish, the set will scale whatever you feed it, to match the screens own resolution - you can't damage it in that way.

And if you're smacking him round the head?, a piece of 2x2 works better than your dainty hand

Some older LCD monitors don't display properly at anything other than at their default resolution, but I doubt that using a lower resolution matters in terms of doing any damage. A higher resolution, though, probably won't work at all, and a constantly higher refresh rate could, potentially, cause damage. But simply experimenting to find which is best has never caused any damage that I could possibly measure.

My TVs are both much better in this regard, and I can run whatever resolution I like (aspect ratio notwithstanding) and they both look fine. LCD HD TVs do have a lot of different circumstances to take into account, so again I would doubt that it is possible to damage them by using a variety of different resolutions, if you so wished.

Please explain the mechanism by which inputting a higher refresh rate than an LCD monitor will accept will damage it.

Common on CRT monitors, feeding it too high a line frequency fries the line output stage.

Shouldn't be any problem on LCD monitors though.

True, which is why I specified LCD.
