This looks about right for a CRT television (not a monitor) running a PC output through a crappy HDMI to AV adapter. You’re never going to get good results this way. If you want sharp computer graphics, you need a CRT monitor. If you want something that looks sharp on a CRT television, you need a proper video source running at a native 480i or 240p.

r/crtgaming on Reddit: Is it normal to have such low sharpness on the Samsung CRT?
March 31, 2025 -
This is a Samsung cl21z58mq CRT connected to the AV with an HDMI adapter, I've already tried adjusting the flyback focus, configuring it in the TV menu and nothing seems effective, the image sometimes seems to shake a little but it's not that bothersome. What should I try to improve this CRT?

This is an actual TV, or is it a computer monitor? SD CRT TVs make for terrible monitors. The text will be basically unreadable. This is normal, due to the dot pitch and focus abilities of the CRT. Computer monitors always had much better CRTs in those terms for that very reason. Play a DVD on it via composite or S-video (if it has it). If the picture looks good like a DVD should, then the TV is fine. TL;DR you'll never make a standard TV into a good computer monitor.

Q80T - CRT effect on HDR gaming mode - Samsung Community
December 4, 2020 - I bought the 55 inch Q80Τ about a week ago and immediately got the 1403 update. After i plugged my ps4 to check the gaming experience i noticed on HDR gaming only, in dark areas or scenes when its static without motion, i see like refreshing horizontal lines on screen going from down to top, like old crt TVs but not very noticable.

r/crtgaming on Reddit: How good are samsung crts?
March 9, 2021 -
Found a samsung crt with a component input (didn't check the model number sadly) across from my street and I plan on using it as one of my main gaming setups once I move out in 2 months. How's the picture quality and are these pretty good for input lag relative to other crts? (I play smash bros melee competitively so this is super important for me) Any help would be greatly appreciated.

The last CRT I ever purchased at a retailer was a Samsung HD set when the XBOX 360 came out. Worst geometry I’ve ever seen from a new set. It was driving me insane to the point I just gave it to my parents. They still use it as their main TV.

Avoid their slimfits in general (they tend to have horrible geometry) and HD CRTs (unless you know you can take advantage of it, not unique to Samsung).

Samsung CRT-HDTV! | AVForums
September 30, 2005 - These are clearly seen on a TV, but not so obvious on a monitor where they are closer together. From the scanning electron beams point of view, these are effectively homogenous, so it doesn't exactly matter where on the screen the beams land, they will always hit a phosphor of the right colour. Think about it, what would happen if that wasn't the case? The beams cannot register exactly with every phosphor because CRT geometry is never perfect.

Why did TV tech go from CRT curved screens into flat TVs and now back to thin curved screens? - Quora
Cathode-ray tubes went the way of the dinosaur because of their analog, size, and resolution limitations compared to the newer digital format but Samsung’s curved flatscreen TV is another in the long line of failed Samsung gimmicks. To view it, one has to be situated at a set distance in the center and lighting (including window light) has to be just so or harsh reflections will ruin the viewing experience. ... CRTs are naturally curved.

r/crtgaming on Reddit: A good CRT filter for general use/that works everywhere
November 25, 2025 -
Hi folks, so I have a few really nice CRT monitors but I've run into the problem of them being too "good", they sort of just look like a modern screen and don't feature much blurring or scanlines (unless I'm at 480p) or what have you. I was thinking of just running a shader or filter, but I'd like it to be global or be active constantly, not game/retroarch/emulator specific as I watch old shows and what not on them as well as games. Could anyone recommend me such a thing if it exists?
Thanks!
Edit: Found out that crt-royale has been ported to reshade so all good!

You could put some of that frosted privacy film over the screen.

Check out ShaderGlass . It works over a good number of applications and works in browsers. It doesn't seem to work with videos which have some form of HDCP (type of copy protection you can get on the likes of Netflix, if you're unfamiliar) and some applications won't work with it when in full screen, but works fine with most videos in browsers and with VLC player. If you can get the monitor to either 1440x1080 or 1920x1440 then I suggest maybe checking out some of the Retro Crisis shader presets; you will need to scroll down a fair bit to find the folder for them in the RetroArch Library folder. There are ones to emulate using 480p on a PC CRT monitor, as well as ones for console games. The PS2 Clean and Dreamcast Clean ones may be worth checking out for 480i video to emulate how it looks on an SD consumer CRT, but the effect is a little strong for my taste when not using a 4K version of the shader preset but you might find them acceptable. The CRT Royale Fast presets could also be worth a look; they are in the folder "crt-royale-fast" which is contained within the Presets folder in the RetroArch library. You will also likely want to play around a bit with the shader parameters for the Retro Crisis presets. You can try changing the LUT Colours for different colour presentations, and I definitely recommend reducing the slider for Add Noise to zero. For some reason there is added noise even for presets emulating RGB signals like on a VGA CRT, or RGB SCART/BNC for an SD CRT. If you get a presentation you like after adjustments then you can save it as a profile under the Processing menu and just load the profile next time you want to use it as the shader preset will go back to its defaults next time you use it. Here is a video by Retro Crisis showing you how to use ShaderGlass from before his shader presets were added.
