请教HDMI液晶屏（800x480）的参数设置问题

钟工 LV 7

硬件平台mq-pro, 软件tina-linux
1）一台支持HDMI显示器
2）一块HDMI液晶屏，支持800x480分辨率下面是它的连接
https://item.taobao.com/item.htm?spm=a1z09.2.0.0.77dd2e8dU1iETV&id=646568908641&_u=21njr0q8040

软件上电默认是模式2 (720x480P)，在HDMI显示器可以看到小企鹅，填充/dev/fb0内容可以看到变化

但是接到HDMI液晶屏上，屏可以点亮，但是只是呈现一片白色，填充/dev/fb0无变化
可能是参数的问题，分别读出EDID和解码如下：

Warnings:

Block 0, Base EDID:
Detailed Timing Descriptor #1: DTD is similar but not identical to VIC 16.
Block 1, CTA-861 Extension Block:
Video Capability Data Block: IT scan behavior is expected to support underscanned.
Video Capability Data Block: S_PT is equal to S_IT and S_CE, so should be set to 0 instead.
Detailed Timing Descriptor #2: DTD is similar but not identical to VIC 16.
Display Product Serial Number is set, so the Serial Number in the Base EDID should be 0.
EDID:
CTA-861: Multiple native progressive timings are defined.

Failures:

Block 0, Base EDID:
Display Range Limits: 'Bare Limits' is not allowed for EDID < 1.4.
Block 1, CTA-861 Extension Block:
Video Capability Data Block: IT video formats are always overscanned, but bit 7 of Byte 3 of the CTA-861 Extension header is set to underscanned.
Detailed Timing Descriptor #2: Mismatch of image size 597x336 mm vs display size 340x190 mm.
Required 640x480p60 timings are missing in the established timings and the SVD list (VIC 1).
EDID:
Base EDID: Some timings are out of range of the Monitor Ranges:
Horizontal Freq: 37.878 - 67.500 kHz (Monitor: 84.000 - 84.000 kHz)
Base EDID: The DTD max image size is 597x336mm, which is larger than the display size 340.0x190.0mm.

EDID conformity: FAIL

哪位大侠熟悉EDID参数，能够指点一下，可以调整哪些参数使得能够适应这个液晶屏，谢谢了。
