The display is very blurry, the focus button is broken, it can t be adjusted, is there anything else

There are many reasons why the display is blurry, it may be too much dust inside, or it may be that the device is damaged, and you had better send it for professional repair.

Some graphics cards have tuning, see if yours can or not.

Only repair the keys, or lead the key wires out.

Display adjustment relies on buttons, and some LCD monitors generally have automatic adjustment buttons

The desktop button is broken, and there's not much you can do about it except to press it a few more times or fix it

Monitor, open the shell to repair it, replace the button.

I suggest that you fix it too... It doesn't cost much to fix it.。。

You see if the monitor has a control software, which can be adjusted.

Personally, I think there is no way to adjust it. Because adjusting the content is nothing more than that: the width of the screen and the brightness of the screen.

There is still a way to solve the screen color, that is, the screen brightness. But the width is no way to solve.

The brightness of the screen can be adjusted according to the software that comes with PS, Adobe Gamma (in the control panel) of Photoshop, and there is nothing else that can be done.

Your problem is a hard problem, and you can only fold it and fix it yourself, which is very simple.

Are you a discrete graphics card? If so, the color correction can be compensated to a certain extent.

Since I basically only work with nvidia's graphics card, I'll just tell you about nvidia's Open nvidia's control panel (right-click on the desktop, vista, xp are), in the penultimate item, and then adjust it to your liking.

But this one starts with Windows, which means that if you don't look good before Windows enters the desktop, I can't help it.

This method is a way to compensate, and I don't know if it will work for you.

In fact, there is a way, but you can't fix it yourself, just remove the monitor and short or debug the button in front. I haven't tried anything else to compensate, or I'll find a professional to fix it or replace it directly. The way is not good, don't mind, leave the points, thank you for your cooperation.

It's very simple, smash it and buy a new one.

Shortcut: FN function key + up arrow key (there is a sun-like icon on it to indicate brightness).

(outside of warranty), will you do it yourself? Carefully open the panel shell after the power is off, and carefully wipe it with alcohol at the contact between the button and the electric board, many reasons are handled like this (similar to the TV remote control board).

Otherwise, send it for repair.

Yes, except for the LCD, you turn the monitor on and turn it down to a few buttons on the bubble.

There is software to adjust the brightness of the display.

I recommend you to try it.

This can only be adjusted by the button,There is no way,You can only repair the switch and then adjust,But now it's not worth it to find a maintenance department to repair,A second-hand CRT display is only a few dozen yuan,If you repair, the maintenance fee is enough to buy a second-hand monitor。

If you are an antique, you will do it yourself, dismantle it, and see if you can tinker well, and you still have a sense of accomplishment if you tinker well.

Let's get a new one! If it doesn't work, send it for repair, but it's not cost-effective!
