Originally posted by **NatachaJee** July 3, 2024 Hello, First, I'm grateful for the TFT_eSPI library. It's so useful and make my project look good. But unfortunately when I push EN on ESP32 or turn-on display the screen have a flash (around 1 second) like a picture then show normal screen. Could you please suggest me for fix it? I use #include and set up width 170 and height 320 already. ![449064100_1166676661081931_6154001224789516348_n](https://github.com/Bodmer/TFT_eSPI/assets/166633710/8b539003-6bf8-46bb-b979-b88fde5aeb66) ![448991599_1136962744026851_5133437046742820641_n](https://github.com/Bodmer/TFT_eSPI/assets/166633710/c6fa6cea-e3a2-45b6-b92d-eef9b72645b5) ![449665218_995719658894218_7950749576685487244_n](https://github.com/Bodmer/TFT_eSPI/assets/166633710/6750733a-bd17-49e1-9783-57d90f2f9111)
