CRT TV unstable/vibrating image

[Xenosis]

Hello

Trying to setup a PC to use my new b&o mx8000 28" crt TV, but the picture is very shaky/vibrating around all dark edges, like the desktop icons and the top edge of the windows taskbar, buttons inside vmmaker..

I'm using Arcade Forge's UMSA and SCART connected to my hd 7850 using dvi-i/vga adaptor.

I followed this guide:
http://geedorah.com/eiusdemmodi/forum/viewtopic.php?pid=1052

Even tried connecting a smaller mx4000 crt, but same shaky/vibration in windows..

Also did a quick test running a rom, but I did not get any info about switchres like in the tutorial.. I got this: https://imgur.com/a/yxEhYPI

Can anyone tell me why the picture is vibrating so much?

If the flicker you're talking about is occuring on horizotnal lines but not so much on vertical lines, then it's probably just interlace flicker. The only real way around this is by using Beta 10 of crt_emudriver, as this is the last version with the flicker filter. It might even be that the USMA is ---steaming pile of meadow muffin--- at interlaced modes... all of which implies you're running an interlaced mode like 480i for MAME, where the game in your picture wants a 240p mode (224 + 8 blank lines each side, so no vertical scaling).

Did you closely follow the crt_emudriver install/setup guide for the 5000-series and up Radeon cards?

Also, that screenshot, is it showing GroovyMAME or vanilla MAME? GM would normally show two resolution lines - one like your screenshot does, telling you the game's native res, and another telling you what resolution switchres has chosen (i.e. the video mode you're actually running at.)

UMSA does interlace just fine.

It looks like horizotnal lines that are flickering up and down.. In the dark areas like shadows on buttons etc..

I followed every step in the guide I linked to, and everything went smooth.. Except i did not thave the streetfighter 2 rom in my 0.213 romset.. But did try a bunch of other versions of streetfigther that worked... However I have not seen switchres showing any info yet..

I'm pretty sure, I only have Groovymame on that PC.. But I will try reinstall hyperspin and groovymame later today..

One thing I've noticed in the advanced settings monitor tab.. I am only able to choose between 30hz interlaced and 60hz interlaced.. Also i'm running 640x480 resolution in windows.

Some "hints" since it's hard to diagnose your supposed problem with so little info:

- If there's not a Switchres line at the bottom of every machine information window when running a game, you're not using Groovy MAME.

- Leave the frontend thing till everything else is properly working. Use command-line or MAME's UI instead.

- You don't right-click on the desktop nor go to the graphic card's properties to change Window's current video mode. Use only Arcade OSD for this, which you should have downloaded with CRT Emudriver. Open it to see what's the video mode highlighted and which ones aren't, since those are the ones you've installed successfully.

- Flickering goes together with interlacing, and some "vibration" with it. You may be experiencing a non-issue.

Okay.. installed groovemame64 and now I got Switchres working and showing .. And big difference in games.. No flickering, also the little screen tearing I had is gone..

However windows desktop is still terrible to look at.. But that's not important.. If just my games and hyperspin looks correctly.. And when I look through hyperspin, I don't really notice any flickering..
