The downside to HDTV’s: Standard Definition (SD) DVD and TV looks like dog poo

10 Apr

Ok, for those that don’t know, when you watch ‘normal’ TV (Standard Definition otherwise known as SD) on a HDTV, the image looks like crap.

Why? It’s because HDTVs are fixed resolution. Even CRT HDTV’s do not have the ability to switch resolution like a CRT computer monitor. This is done to save cost. a 57 inch HDTV with the ability to switch resolution would be astronomical in cost.

So your HDTV is fixed at 1080 resolution. Refer to the following chart:

You will always get cruddy SD video on a HDTV, especially very big HDTVs because of this fixed resolution issue. You are taking video meant to be played on a 480 resolution SD TV, and blowing it the hell up to stretch and fit a 1080 resolution screen. The result is shit:

The only solution is to keep watching your standard DVDs and TV on a regular SD TV. That is what I will do. I have a 36″ SD CRT TV and my regular DVD’s look great on it, but look like pig vomit on my 57″ HDTV.

My 36″ SD CRT displays the image at the native resolution but at a large physical size, with zero scaling resulting in the best quality relative to physical display size.

So let this be a lesson: If you upgrade to a HDTV dont throw away or sell your old CRT TV, your dvds will still look best on there.

    not I said the cat
    Honestly, I don’t have any problems with watching DVD’s on my HDTV. they look great. I use my x-box to play the DVD, which is hooked up to the HDTV with a compositive output. The results are fine.
    Maybe you’re doing something wrong? I’ve owned mine for a year and never any issues with that; and i watch HD programming all the time, so I understand what the resolution looks like at 1080; while my DVDs aren’t that, they look great
    Maybe you’re missing something.

    even if it had the power to change resolutions, the resultant pixels would still the the same size to fill up the screen. it’s just the standard of taking a “small” picture and stretching it to fill a big screen. i guess a purist solution would be to view it from 20 feet further away 😉
