am335x lcd display emissions

Hi,

I am using AM335x-EVM as reference and changed the resistive screen with capacitive one.

Everything is working but I am noticing few problems in display. For a particular bitmap (black and white gradient), display has following effects:

- aliasing effect

- high emissions

I am using the default device tree configuration for LCD with DRM driver

	panel {
		compatible = "ti,tilcdc,panel";
		status = "okay";
		panel-info {
			ac-bias           = <255>;
			ac-bias-intrpt    = <0>;
			dma-burst-sz      = <16>;
			bpp               = <32>;
			fdd               = <0x80>;
			sync-edge         = <0>;
			sync-ctrl         = <1>;
			raster-order      = <0>;
			fifo-th           = <0>;
		};

		display-timings {
			800x480p62 {
				clock-frequency = <30000000>;
				hactive = <800>;
				vactive = <480>;
				hfront-porch = <39>;
				hback-porch = <39>;
				hsync-len = <47>;
				vback-porch = <29>;
				vfront-porch = <13>;
				vsync-len = <2>;
				hsync-active = <1>;
				vsync-active = <1>;
			};
		};
	};

I have another reference kit using the same display but artefact and emission are less for same bitmap.

Is there something that I could try changing in the dts file ?
