I insisted on you soldering something up just to test if this solution will work for your needs. It works great in text and 99% 320x200 mode games, but some do weird resolutions and in that case vgatv program fails completely. At lest you will still have your converter box to hot swap and handle incompatible games/programs.

I edited my last post, I don't know whether you saw that - please take a look. I found few solutions, maybe they would work?

the price is right and seller seems to know what he is selling. Its weird there is no external supply for signaling TV (switching to rgb mode and disabling blanking). My ancient cable had a passthrough keyboard plug to steal 5V.

Well yeah, but soldering cable just to test requires to buy resistors and "bunch of loose wires", which I don't have, so with shipment it will probably be more expensive than buying the right cable. Especially if the one which I found in last post is very cheap. So you think that I can buy it and check? Even if it won't work, I will have vga input to solder, which you told me to buy anyway, so it seems to be a good idea, right? Maybe it will work and any soldering will not be necessary.

stop deferring decision to me 😀
yes, that last cable seems to be ok according to the seller. Im still surprised it oesnt require external supply, scart needs it

pin 8 is only needed for automagic detection of external signal on SCART connector, most TVs let you manually switch inputs, pin 16 switches between composite and RGB input, hmm maybe manually selecting input with TV remote overrides that one too.

but if that CRT is not for arcade nostalgia I would still go for https://allegro.pl/kategoria/monitory-k ... 17&order=d picking something without scratches/blemishes/bad lines. For example https://allegro.pl/oferta/monitorhp-l1740-17- … uki-12812510206 will probably sell <40zl

I think I have another converter somewhere.. With S-video and RGB.. Have too look..

Maybe it's using the power that was intended for the EPROM in VGA monitors?
You know, EDID or DDC stuff.. There's a chance one of the pins has 5v or so. Not much current, but maybe enough to trigger a transistor in the SCART monitor.

I asked seller whether he is sure that this cable is vga-scart and not opposite. Guess what he answered me? "I have no idea, I never connected it". So probably it's still scart to vga. It seems that there is not any, even a single offer in the internet for vga-scart cable, only opposite. For vga to scart I find only converters.
What would you say about vga to rca and then adapter to scart? I have the adapter in home, so I only need vga to rca. Will it work? This is what I already have:
https://allegro.pl/oferta/adapter-przejsciowk … ideo-8857412029
And for example I could buy this one:
https://allegrolokalnie.pl/oferta/kabel-vga-d … inch-35-cm-nowy
What do you think? Will it work?
Why I want tv instead of monitor - because I want to use it also for vcr to watch my vhs tapes. Vhs works great with this tv. Also I think that image on tv looks better than on monitor - because on monitor it's too sharp and looks like on lcd, tv gives unique look. But this is just my opinion. Another reason is that I already have tv and it would be hard to get rid of it 😁 Because nobody wants crt tv these days and I wouldn't dare throwing it to trash. And I want crt, not lcd, because I already have lcd which I used for few years with this computer. Now I want to go full retro with crt.
Another idea is to buy Averkey if it works - I found this offer:
https://www.olx.pt/d/anuncio/avermedia-averke … er-IDFksyX.html
It's probably in Portugal. I already contacted seller and he said that shipment to Poland should be about 16 dollars, so it's not that much. It's Averkey 100 Pro - there are few versions of Averkey in the internet, I also found Averkey 300 Pro and 500 Pro - I don't know what is the difference between them. Averkey 100 Pro will work?

I think I have another converter somewhere.. With S-video and RGB.. Have too look..

If it will work with your computer and tv, please let me know. Maybe this converter will be available in Poland and I won't have to pay for shipment from another countries.
For soldering the cable I don't have the right equipment - my soldering iron is old, big and heavy and it's almost impossible to use it for tiny little cables which are close to each others.

another scaler like the chinese thing you already have, I have no opinion about it. Might work perfectly, might cut picture off.

this is basically this cable, but fancier implementation. VGA-SCART is only ever used by Arcade people nowadays, not as cost cutting measure.

I still might have my 30 year old cable somewhere, but I think you should just buy a $10 17 inch lcd 😀

So now I completely don't know what to do. In whole internet I didn't find even one single offer for vga to Scart cable, like they don't exist. Only converters. So you are telling me that the only way to do it is to have most simply cable vga to Scart, which noone offers for sale in whole internet? There are many vga to RCA cables, but vga to Scart - not even single one. I don't want LCD, I prefer crt. User Jo22 has AVerKey and he showed us on video that his 286 and 386 computers work perfectly with this. I just don't know which version does he have. AVerKey is very old converter.

No, The description says that this is for connecting Atari to vga monitor, so it's also Scart to vga.

EDIT

Ok, and what about this one?
https://cablematic.com/en/products/vga-to-sca … mscart-m-VG001/
The desciption is good, but it's in some other country, so the shipment will be expensive. It seems to be the only offer which clearly says that it's vga to Scart, even in the reviews someone wrote that he couldn't find it anywhere else. I don't think that I will find it in Poland. But the description also says: "this cable is not a signal converterand that it will only work by connecting devices that work with the same type of signal (for example PAL)", so will it work?
And about soldering my own cable - do you think that I am able to do this with this equipment?

just because something is in a box instead of fitting in a plug doesnt mean its converting signals

SCART is a very old, obsolete technology just like CRT TVs and analog VGA. Its all ancient history.

as long as you have a cheap multimeter and some scrap electronics to pull cables and two resistors from 😀

Another vga to SCART converter project https://www.epanorama.net/circuits/vga2tv/cindex.html this one has elaborate H V sync combining circuit, also custom driver for cirrus logic with source code available.

Seems that I will have to solder it.

I have a multimeter, but I don't have cables and resistors. I can buy resistors, cables probably also, but how to search for cables in internet? I don't have anything to pull them from.
Also, would you be kind enough to explain me on private message in polish how to do everything? I can speak english, but when it comes to making own cable I need clear instructions so I won't mess anything and english becomes hard when I'm reading about this kind of stuff. So if you will agree to help me in polish in private message, then I can try to do it.

about vga-to-rca https://pointerclicker.com/do-vga-to-rca-cables-work/

"VGA to RCA cables work, but they work with _particular types of graphics cards_. For instance, they worked with a few NVidia desktops manufactured between 1997 to 2005. These desktop graphics cards have a setting to change the VGA port to work as an output."

do you seriously not have a single broken piece of electronics in your house/garage/basement? 😮 ill look for my old cable, if I can find it Ill send it to you

I have old broken tape recorder, but without cable. I also can "destroy" one scart cable, because I won't need it anymore if this will help, but I don't know whether it has 1K resistors inside. But if you could send me your cable then it would be the best - as you can see my soldering iron is too big for this kind of stuff and I will probably end with all pins soldered together.

When you will be able to check whether you have it? I'm asking because Averkey seller waits for my response.

Sorry, I went thru my hoard and sadly cant find it, means its berried deep somewhere in the basement 🙁

No problem, I think that I will try with the Averkey converter. Additional advantage is that I will be able to transfer sound to my tv, which would be impossible with simple cable. If it worked for user Jo22 with his 386 computer, then it also should work with mine. So we will see whether this will work. But thanks for your informations.

I use an Extron RGB 192V for combining sync to go from my PC (running VGATV) to my TV

Looks nice, but it's more expensive.
I already bought this Averkey (10 euro for Averkey and 9,95 euro for shipment, so it's very good offer comparing to offers on Ebay), it should come to me next week, I will let you know whether it works for me.

forgot about one more option - opening up and looking what chip its using, maybe someone has a project using same chip or knows how to reprogram it

Hi,
I already have Averkey 100 Pro. It fixed my problem - the screen now fully shows on the crt tv. But quality is a little worse than on the previous converter - it's probably because it doesn't use Scart, but only composite. But it also has s-video, so it will probably give me better image. Don't get me wrong, the image is still good, just a little worse than before. I don't have s-video cable, but I have an adapter, which converts both from composite and from s-video to scart. Now I use composite to scart, so I will buy s-video cable and it will probably give me better image. But I'm happy now - the screen still looks great, just a little too bright and a little more blur than before. I can probably adjust it with tv settings (I saw in manual that this tv has sharpness settings), but I don't have a remote. I also need minijack-to-cinch audio cable to get sound on my tv. So I need to buy s-video cable, audio cable and a remote and I think that I will be completely happy. Thank you for your help!

Ok, just to finish this topic - I mixed s-video with composite and they both together give me beautiful screen. I'm really happy with the result - here you can watch it: https://www.youtube.com/watch?v=eOS2r9Y-iiU . Thanks again!
The only disadvantage is that Averkey gets very hot after few hours and starts to show some artifacts on the screen. But it's not a big deal, because I usually turn everything off after using it and I never play for that long.
