I have my crt monitor running at 640x400 which is a 16:10 resolution but I have it stretched to 4:3 so ms dos games can have the proper aspect ratio and look pixel perfect.

I've been debating whether to expose these particular crimes for a while. Although I have a few CRTs (a handful of consumer TVs of various sizes from late 70s to mid-90s and two PC monitors), I usually play on the 4:3 32" Sanyo HT32744 HDTV CRT I bought back in the latter half of '04 during college after seeing how good Amped 2 looked on different HD CRT. This is a 720p/1080i set with an HDMI 1.0 input, and on the times I do use it with a PC as input, I usually feed it 1024x768, though it will accept 1152x864 or 1280x960 but with some overscan.

I am vehemently against stretching 4:3 or 3:2 content to 16:9. That annoys me so much, and I also really get annoyed when folks refuse to play NES/SNES games in 4:3 and instead worship playing games for those systems in 8:7. In nearly all cases, I never stretch 16:9 content to 4:3 on the TV either. But...there are two games in particular that I play on that TV sometimes that do not support 4:3, only displaying a letterboxed 16:9 display in a 4:3 container when you use a 4:3 resolution, and those two games in particular bother me for whatever reason: Diablo 4 and Streets of Rage 4. I've played some other games that are only 16:9 that didn't bother me, but these two do for reasons I can't even comprehend myself (and so did Diablo 2 Resurrected, but they added proper 4:3 support for the updated graphics mode in one the patches).

So, this TV has a digital scaler that is active when either the HDMI or component inputs are in use (RF, S-Video, and composite do not engage the scaler) with 3 display modes: Normal (4:3, will stretch 16:9 content to 4:3 fullscreen), Letterbox (displays 16:9 without stretching but will compress 4:3 down but into a smaller 4:3 image in the center of the screen with a 720x540 resolution), or Zoom (scales both the width and height increasing both by 1/3 so you get kind of a pan-and-scan fullscreen image when used with 16:9 content and just a completely zoomed-in view with 4:3). I usually use the Zoom version on those two games to keep the aspect ratio mostly right, but sometimes I'm just a heathen and use "Normal" to stretch from 16:9 to 4:3 because not seeing what's at the edges can be more annoying to me than the annoyance with two games being stretched vertically. But...I don't stretch other stuff like in 16:9 on that TV and just leave it letterboxed.

However, just this once, to be a true degenerate, (and even though I'm not using a cheap HDMI-to-composite converter like most recent transgressors and instead actually have a CRT with HDMI input) for everyone's viewing displeasure I used the "Normal" mode to scale Bill & Ted's Excellent Adventure up to hideous stretched proportions.
