Don't expect helpers to have Your circuits as their daily playground.
Please post links to the datasheets of the circuitry You use. I guarantee that helpers are capable of reading datasheets and then reply.
Your reply does not have nearly enough information. You may not have spent enough time reading the link that was provided in reply #2.
You say absolutely nothing about software.
#include <ESPVGAX2.h>
#include <images2/pirate256.h>
#include <images2/pirate320.h>
ESPVGAX2 vga;
void loop() {
while (1) {
//never return from loop(). never call delay() or yield() functions
}
}
void setup() {
vga.begin();
#if ESPVGAX2_WIDTH==320
vga.blit_P((uint8_t*)img2_pirate320_data, 0, 0, IMG2_PIRATE320_WIDTH, IMG2_PIRATE320_HEIGHT);
#else
vga.blit_P((uint8_t*)img2_pirate256_data, 0, 0, IMG2_PIRATE256_WIDTH, IMG2_PIRATE256_HEIGHT);
#endif
}
Read. The link. Again. Carefully. Please.

Generally, it will tell you that you need to really explain your problem or question and provide all the relevant details about your project materials and environment.
nodemcu not boot a monitor still seeing check video cable
Again, please REALLY EXPLAIN your problem or question and provide ALL the relevant details about your project materials and environment.
So far, you have not done that. We can not guess the details of your hardware and software.
If I understand your latest post, your circuit is not producing a VGA signal as expected. Thus you have not even reached your second problem of attaching mouse/keyboard.
We need to know the source of this project. Did you design it? Did you copy some design? Did you port it to a different processor? There are a thousand facts you said nothing about.

i want to wireing my old hp compace monitor 1280*1024 with only arduino nano v3.0 or esp8266 nodemcu v3.0 please i cant vigure out how to put the wire directly to vga monitor
Did you consult online wiring diagrams for VGA interface?
yes
looking in this link please i need to put the jumper wires dirctly with only one nano v3.0 or nodemcu 3.0 https://www.instructables.com/Arduino-Basic-PC-With-VGA-Output/
how to do that?
The VGAX library says, "This is a VGA library for Arduino UNO and Arduino MEGA." What makes you think you can run it on an ESP processor?
no there its running on arduino nano r3 v3.0
Okay, now I see the ESP8266 version. Then you might have made a wiring error.

no every thing are good but when power on my monitor still get check video cable then i try much to find out how to do that finally get this link work fine with nano r3 so i have it
Aren't you assuming a lot? You can't really be sure your wiring is good just by having a lot of personal confidence. I think testing it with two different devices, one works and the other not, just proves that the non working one has some problem (that you made, since you made the interface)
So many people insist, "no, my wiring must be fine" and suffer through endless pain for not thoroughly investigating it.
on esp8266 is it should to wireing to 5v and gnd or only like befor without any voltage only micro usb to esp8266
How do you know, you didn't just make some simple physical wiring mistake? Not just a theoretical error...
i follow the instruction and steps many and take care
