Any experience with Pi Zero + 2.4" TFT LCD Touch Screen
Any experience with Pi Zero + 2.4" TFT LCD Touch Screen
Hi all,
I've recently brought a 2.4 Inch TFT LCD Display Module Touch Screen (http://www.ebay.co.uk/itm/162083430896? ... EBIDX%3AIT) to go with my Raspberry Pi Zero and wondered if anyone else used one with Retropie?
I've used fbcp to copy the HDMI to the screen but it is a bit laggy when running RetroPie in-menu, as well as in-game - not so much that it isn't playable but its noticeable. I've tried a number of different resolutions as well.
I just wonder if the screen itself is just not decent enough to cope with the games or whether I just need to tweak the configs.
Any help would be most appreciated

Great to hear - just means I need to play more with the configsChedda wrote:I have the 3.5 inch version and it runs fine without any issues.
Any suggestions what might be causing the lag?

Are you outputting to 2 different sources?
The difference I have is that I am using the Adafruit version of the 3.5 tft.

I have tried it with just the 2.4" screen plugged in, as well as also connecting another screen via HDMI (HDMI doesn't see any lag + appears to be working at full resolution, even though I changed the HDMI resolution)Chedda wrote:Are you outputting to 2 different sources?

Not with the HDMI screen, but yes with the 2.4" only.Chedda wrote:If you run with just the one display, do you get lag/ghosting?
Could it be that the pi still thinks the HDMI screen is plugged in and is still pumping out full resolution to the HDMI, while also mirroring to the 2.4"?

Did you hard code that into the config.txt? You can disable the hdmi in the config and see if it is the driver on the display causing the issue.
