I’m using ADC PLL BW set to Medium (setting to High gives me a blank screen) Also have FPGA PLL BW set to Low (again, High gives me a blank screen). The screen jitter at the top definely is a lot less noticeable than when using previous FW versions. Also, setting the Video In Video LFP to Off reduces the jitter even more without affecting the rest of the image.

The above is when outputting to a VGA CRT monitor via a DAC (an HP 7540 to be precise) I also get the jitter when using my HDMI TV, however it is more forgiving and allows the ADC and FPGA settings to both be set to high. Also, if I want to hide it, I can do so by setting the output to 5x which crops off the top of the image anyways (adding a vertical mask of 2 on top of that is enough to completly hide the jitter)

Hey @marqs, so at the weekend I managed to succuessfully mod my 1.6 board and installed the latest dev FW. While adjusting the ADC PLL and FPGA PLL settings did make my picture more stable (and allowed me to enable 240 optimised mode – something I couldnt do before), I still have shimmering/jitter at the top of the screen (tested on all line x modes, plus a few tvs/monitors).

Is this just something I will need to accept will happen when using the RGB Blaster with the original OSSC? I’m guessing this wouldn’t be an issue if I upgraded to the OSSC Pro?

[andychristian]

Thanks marqs, will give that a shot 🙂

Yeah I’m exactly the same – had to bump mine right up to 15 in order to get proper contrast.

Cheers, will give PC mode another look, but the downside for me is when enabled it greys out a lot of the picture options (can’t change colour value etc)

Ordered myself a 480p Scart from RGC, so looking forward to trying that out on AV1.

Hoping that my cropping/overscan issues get sorted too!

[andychristian]

Unfortunately not (old Samsung Smart TV) I just have the option to switch bewtween 4:3 and 16:9 (‘Just Scan’ option is greyed out when in 480p)

It’s a strange one. When set to 2x the picture size is fine, no cropping at the top or bottom. However tv is put into a weird PC mode which results in washed out colours and prevents me from putting into Game mode.

Passthrough on the other hand does allow for Game mode and the colours look much nicer. However top of bottom of image is cropped out (similar to what happens when you try and play 240p content in line5x)

I’m just using the default OSSC settings. Tried switching between Auto/DTV/VESA and changing H.Active to 640, but obviously is not affecting the vertical cropping/overscan

I’m using a standard VGA cable connected to AV3. Looking to get RGC’s new 480p Scart lead and wondering if that will solve anything and maybe give me some more control of the image.

[andychristian]

Cheers, tried that and picture looks good.

Don’t suppose there’s any way to fix the overscan when using passthrough?

[andychristian]

@xtrasmiley I used an app for Mac called ‘Etcher’, which allows you to write an IMG file to SD. Just simply rename the .bin file to .img before you start (also, ignore the warning about the image not being self-booting, as it doesn’t need to be) Takes seconds then you’re good to go with the update process on the OSSC!

[andychristian]

Has anyone experienced any audio issues with the latest firmware? Since applying the update I’m getting no audio output at all with my 1.6 connected via Scart to HDMI to my TV.

EDIT:

Never mind! Genius here installed the wrong firmware version! Working now since using the -aud one!

[andychristian]

Here’s a before and after shot using the settings mentioned above. Really happy with the results!

[andychristian]

Just tried out the reverse LPF setting on my regular old multi-chip Super Famicom and the results are amazing! Now much more on par with the kinda picture it get from my Mega Drive. Who needs a 1Chip eh?

Tested on Line3x mode at 256×240 optimised – I found 9 to be the sweet spot for me removes all noticeable signs of bleed

Thanks @marqs!

[andychristian]

Have you tried cycling through the different input types? (the left button on the front of the OSSC) Usually just the one press switches to RGB Scart.

[andychristian]

Received my 1.6 – works great with my Samsung UE39F5300AK, handles pretty much everything I throw at it.

Mega Drive (60hz modded), Super Famicom, RGB Modded NTSC N64, PS1 (60hz modded) – All work with 2X, 3X, 4X and 5X. The OSSC’s almost non-existent input lag combined with my Samsung’s game mode make everything an absolute dream to play.

My Dreamcast also works in in Line2x mode via VGA – looks amazing. HOWEVER. When in this mode, my Samsung’s Game Mode is automatically switched off an becomes unavailable. The input shows as ‘1280×960 @ 60hz’ on my TV. I’m guessing this is because this is a non-standard HD signal that causes it to switch off? Anyone experienced similar, or know of any tweaks, either on my TV or on the OSSC than I make to get this enabled again?
