Screen crop?

Post#1 » Thu Aug 11, 2022 4:51 am

Hi everyone.

I have purchased my second ever Dreamcast. The first one did not work at all :(

The problem with my 2nd console is that the screen is cropped at the left side :(

This is the only TV I own for me to test, and I can only choose between the screen ratio (4:3, 16:9), and i cannot zoom in or out. All options give me the same outcome.

Any ideas how to fix this? Is this a common issue?

I've attached a screenshot outlining the issue.

Thanks in advance !!

Hello, unfortunately it's a common issue that depends on how modern TVs manage the Dreamcast unique signal.

What cable are you using?
If you are using a VGA cable, simply disconnecting and reconnecting the cable AFTER the console reach the BIOS menu screen (of after you start any game), this re-center the image.

Hi :) thanks for the reply.

Glad it sounds like an easy fix and is due to a modern TV.

I believe I will have to obtain a CRT Tv.

I've attached a photo of the cable I'm using.

I have been disconnecting and reinserted the cable but unfortunately it doesn't resolve the problem :(

Your using scart this fix above is for VGA.. If you tv has vga just get a vga dreamcast cable cheap on ebay..

Hi

Your cable is a SCART, unfortunately this trick doesn't work with this cable, only works with VGA cable.
I don't know if there are RGB SCART that can solve the screen crop issue on DC, I'm searching for them too.

I see :/

I am picking up a 14 inch CRT TV next week.

If this doesn't solve the issue I will just sell the DC and have done with them as that will be 2/2 DC consoles owned that dont function like they should :(

Not the console it's the display that cant handle the output./.

with a CRT you will be fine, the image will be centered, after all DC was developed for that TV technology.

But on modern displays it's better to go for VGA (or VGA + HDMI) and use that trick.
