Can I use this for AGA/RTG switching?

Smiley · 20 November 2006, 19:34

Will one of these work ok for RTG/AGA switching?

It costs about £10 shipped from ebay.

Ignore the keyboard mouse connectors.

It switches the vga port using a button on top of it.

Its £40 cheaper than the one from amigakit although a bit more messy.

Yes. It's a bit overkill since you won't be using the ps2 ports, but it'll work just fine.

Smiley · 20 November 2006, 21:01

Might buy one, paint it beige and attach it to my tower somehow so it doesnt look such a mess.

Seems to be the cheapest option so far.

Will video be reduced quality due to it being a cheap product?

Jope · 20 November 2006, 21:33

Probably the image quality will suffer somewhat. Use the best (thickest) VGA cables you have.

I use one of these. All works well and doesnt look too bad either....

Smiley · 20 November 2006, 22:03

How big and heavy is that switcher? ^

DDNI · 20 November 2006, 22:06

my switcher about is 12cm deep 20cm long and 6cm high weighs about 300g approx.

Dismantle it and extend the switch wires so you can mount the switch on a front panel while keeping the ugly purpleness hidden inside the tower.

Oooh nearly forgot: many KVMs are powered from the PS/2 ports and won't work unless connected to a computer's PS/2 output. It might be powered via the VGA leads or there might be an option for an external power supply. Check it out before buying.

I have the same switcher as DDNI, but I use it to switch between Amiga and PC.
Unfortunately in my case I have found that there is ghosting on the PC side, when using that switcher. It is not severe, but it is noticeable.

keropi · 21 November 2006, 07:19

WARNING!

I had the exact same switch , it does NOT sync to 50hz! so PAL screens DO NOT WORK!
also it can be powered externally....

Smiley · 21 November 2006, 09:21

The purple one or the one DDNI showed us?

keropi · 21 November 2006, 09:51

the purple ofcourse!
DDNI says his work OK...

Does it have an OSD? Strikes me as really strange otherwise. (I'm not contradicting you, just curious why it doesn't work :-)

This is because if you open it up, there's a huge rats nest of wires inside. This results in crosstalk and probably the impedance is way off too, since it's just normal wire.

It can be helped a little by shortening the wires or replacing the rgb + sync signals with shielded wires.. However it's quite tedious work and usually all the wires are the same colour inside, so you need to be careful.

keropi · 21 November 2006, 10:32

no, no OSD whatsoever... it has a 9V power input, needs it to work... and when displaying PAL screenmode, it just stays inactive or something... I got it for aga/rtg switching too, around a yeat ago, and did not work

so I donated to a friend to use it on pc's... You can order a MULTIMEDIA & DESIGN monitor switch from their web-site, and if u use CGX u can even turn it automatic! look HERE!!!

Smiley · 21 November 2006, 12:44

I use a spectrum 28/24 using pic96

It says it has automatic monitor switching according to amiga hardware cx.

Is this true and could I get it to auto-switch between it and the scandoubler?

keropi · 21 November 2006, 12:55

if it has 2 vga ports on the back then YES.
just feed the scandoubler output to the card's input...

Smiley · 21 November 2006, 13:09

Oh right. Yes it does have an inout and output on it.

So I just have a vga cable going from my SD to input

Then a vga cable form output to monitor

So no need for a KVM then?

keropi · 21 November 2006, 13:23

that's right, no KVM needed.
