I tried that but i didnt seem to do anything

What does your config file look like? Can you dump the contents here?

Same as my config basically. :/ That frame buffer thing was straight from an adafruit guide.

I found the problem!

Change this to force 640x480 60Hz:

Code: Select all

hdmi_group=1
hdmi_mode=1

640x480 75Hz:

Code: Select all

hdmi_group=2
hdmi_mode=6

Does hertz relate to frame rate? The more hertz the better?

You're using VGA though so this won't work for me i believe. Framebuffer is still what should fix it for my setup.

Hi,
I tempting to buy this screen.
Is this the product link which everyone get this display from?

http://www.ebay.com/itm/222137248549?eu ... Tags=bu=bu

I got my screen from this seller for $76:

Thank, making the offer

Its the refresh rate of the screen. So if your game runs at 200 fps your 60 Hz screen will still only show you 60 images per second.
If your using composite i also think that framebuffer setting could do the trick!

How was the difference when you fixed it on your VGA? Clear readable text, no cut off of the image?

[Cannikin]

@cannikin or anyone else Did you adjust your framebuffer in your setup file to the native resolution? i.e:

framebuffer_width=640
framebuffer_height=480

Just curious how big of an impact it has on readability/quality. (These lines are already present in the config files but they're #'d out and are set for a higher resolution by default)

Hmm...no, haven't tried messing with the framebuffer settings...but maybe I will now!

Your game image already looked crisp but if your retropie text is barely readable even with that then it should make a massive difference! As if the potential quality of this screen hadn't been unlocked at all.

Hold your fingers crossed. Tomorrow (today) morning I'm going to pick up my shipment:
