1:1 (zero ticks) is a bit skinny IMO. I keep yo-yoing between 3.5:3 (two ticks) and 4:3 (four ticks / center). 3.75:1 is too uneven IMO. A lot of NES games use chessboard dithering which look acceptable using the 3.5 setting but not 3.75.
Many older HDTVs allow the aspect ratio to be manually changed on 720p or 1080i HD content so the 5:3 pixels squished to 4:3 screen aspect work. However there is a widescreen flag in the HDMI signal such that newer TVs use this setting and only allow you to change the aspect on SD 480p/i content over HDMI.
My ASUS 1080p PC gaming monitor has no screen adjustment always uses square pixel aspect over DVI/HDMI regardless of resolution, so I get sidebars with less than widescreen ratios like 720x480 (NTSC) or classic PC resolutions (640x480, 800x600, 1024x768, etc...).
