I've finally found a decent standard widescreen TV. Unfortunately it is not an HD CRT, as I've not had any good luck finding one of those that isn't damaged in some way. It is an flat panel and uses a computer resolution of 1366x768. It works for its primary purpose, which is to watch widescreen VHS tapes without using a pillbox, meaning the video extends to the full display.
It is taking the place of the 4:3 CRT TV which I had the Saturns connected to and that setup will have to get moved to a different place. And it got me to think about what consoles will natively support the new widescreen TV without the use of hacks. I do not want to use any systems or games that will put a 4:3 image onto the screen or use horizontal stretching. So basically just SD (Standard Definition) widescreen content only, such as widescreen VHS does.
I know that the Dreamcast is out because those required edited ISOs. I thought about the PS2 since it does have a widescreen option in the menu. I think that anything that supports Full HD such as the PS3 is out of this discussion, since I have actual HD TVs to connect those systems to.
The TV has inputs for Composite, S-Video, Component and DVI. There is probably an RF connection also. This is an NTSC set in the US.
