Hi All,

I am trying to connect my NMS 8250 to my monitor. The monitor has one VGA and one DVI input. So I bought a Chinese Scart 2 HDMI block. I bought a HDMI to DVI cable and plugged it at my monitor and guess what: a black screen. The samsung detects a signal, but shows no image. Although I am not sure that my Scart 2 HDMI box works, I assume that it works because it outputs a signal. Once I turn it off, the monitor goes to scan mode ( search for analog/digital signal).

So it seems the scan 2 HDMI doesn't do frequency upscaling, just convert to [email protected]/60 hz or [email protected]/60 hz which my samsung monitor doesn't understand.

Anyone have a tip for a new monitor that preferably has scart (I also want to connect an Amiga), HDMI/VGA.

Thanks!

Are you sure it's not a problem with your '8250 to converter cable? Maybe test it with a TV?
Anyway, a few years ago there were some decent LCD models from Samsung which had analog TV, SCART, component, DVI... Basically they worked with anything from retro to modern machines. Quality in 15KHz was good but not great.
I doubt there are "NEW" monitors with SCART. If you want something new (as in 4K/LED/high resolution) your best option would be to look for modern TVs. Those don't have SCART but can still work with 15KHz signal via VGA or component input.
Other than that, look for a cheap converter like the GBS8220 with RAMA's firmware. It gives good results and you can customize the settings as you like.

Hi, I connected the 8250 with scart to my TV and that works. I can try to use a HDMI to HDMI and connect it to my tv with scart to HDMI upgrade. If the scart2hdmi is broken, I will see that, because my TV will not show an image.

I not jumping with joy, if I have to buy yet another converter like GBS8220.

I bought a few converters in the past, but not before I heard from first hand what the experiences were. So I knew I bought something that worked. And so it did.
It's far from the beauty of CRT and not as good as built in the Samsung TVs from a couple of years ago, but it works.
These converters are rebranded quite a lot so it's easy to run into similar units for different prices.
The left computer is connected with such a thing. There's some zooming on it so you might get a better look.

Edit: The right one is one of the last Samsung TVs with native RGB support. Not available anymore, so second hand is your only bet if you'd like one.

Those Chinese converters can be cheap (better order them directly as rebranded imports tend to be much more expensive while not being any better) but it's a bit of hit and miss with their quality.
I found some surprisingly good ones for composite, of all things.

If you want really good quality you should be looking for scaler instead, but they can be expensive.

The converter works, it just doesn't do upscaling towards my monitor. Thats why I need a monitor or TV that can display both my PC and Amiga and MSX.

So your converter worked with the TV? What resolution/freq did your TV report when you used it?
If your monitor doesn't like the vertical freq, you can test the 8250 it in 60hz mode (VDP 10=0).

The box just says its running at either 702HD, 1920HD. Its the monitor that can't handle output generated for TV's.

This afternoon I went to the market with an M and bought a 24 inch TV that has scart, RGB, HDMI and VGA. The MSX screen is centred in the middle because the ratio is 16:9 so I connected it to the HDMI upscale from China and now the image is full-screen looking great. Great solution.

If you would share the make and model number that can help people in similar situations. On a side note: I prefer to have the picture in 4:3 aspect as that is how it was back in the day and games were designed with that in mind... apart from the aspect ratio, how was the image quality over Scart?

the brand is OK, type OLE22640F (it has a DVD player on the right side). Image quality is survivable. OpenMSX is way better. On a bright background (blue after startup in basic), you'll see lines going from top to bottom. They disappear when actually using the machine. In the games I tried (nemesis 2,3, Metal Gear and Usas) I didn't see these lines.

Image quality with the HDMI upscaler is equal to just scart, its only 16:9.
