You need isolate the problem to either the computer or the monitor.

But first, make sure the monitor cables are securely fastened. If they are then you need to swap monitors with another machine to see if the problem moves to the 2nd computer with the old monitor (indicating the monitor is at fault), or if the problem stays with the 1st computer (indicating the problem is in the computer).

If you don't have a 2nd monitor to try, most TVs support computer input.
 
Well most likely is either your monitor or your GPU as @Bill_Bright said above you need to figure and isolate your problem first....so If you have other GPU or other monitor/TV try that and inform us what happens....GL
 
Monitor brand and model?

Monitor is old Samsung SyncMaster E2220

The Monitor is old Samsung SyncMaster E2220 so it might be it

What specific power supply?
650W is not enough detail (get a pic of the lable)

What specific RX480 are you using?(MSI is not detailed enough), get a GPU-Z screenshot and a white sticker pic from the card back or near pcie edge

Did you buy the card new or used?
What drivers are you running?

Have you updated your motherboard chipset drivers?

Have you swapped monitor cables or tried a different video input?

Swap monitors too

No i havent updated my chipset drivers
----------------------------------------------------------------
CABLE
no i havent tried a diffrent input

I asked if the card was new or used, I take it was used, your psu gives me no confidence, take pictures of the card labels and power supply label please, gpu-z screenshot please.
 
I had a samsung sync master monitor for 7-8 years (don't recall the exact model any more) and it started doing something similar. Monitor would just go black.... I'd have to power it off and back on and if that didn't work I'd have to power cycle my computer and power the monitor of and on again.

Problem ended up being bad capacitors on the power board. I found a company on amazon that sold the necessary capacitors for my monitor. I spent about $15 and 2 hours pulling the monitor apart, removing the 7 bad (4 were visibly bulging) caps and soldering the new 7 caps.

I did that work on the monitor about 4 years ago and gave it to my younger brother and he's still using it to this day.

So, something to keep in mind.

My NEC monitor in 2017 exhibited this same behavior, the monitor is from 2001, unsure if its backlight, brick or the powerboard you mention for samsung...

Ok ill keep it in mind thanks for responding :D
 
1. Provide systems specs ... make, specific model number of all componenets

2. Provide GPU Temps and spefically what is running at the time problem occurs.

3. Provide any Event Viewer messages in System Log

4. 6-pn MSI 480-pin or 8-pin. If 6-pin, Id start there

5. Sswapping power and signal cabples and swapping minitors is a great step in eliminating possibilities
 
An obvious question that nobody has asked yet: does this only happen when gaming, or at any time the monitor is on for this long? This can easily be tested by setting the PC power settings to never go to sleep and never turn off the monitor. If it still goes black my money would be on the monitor being bad, if it doesn't it sounds like a GPU issue.

i arledy had it to never go to sleep but it still does the same

"Still does the same" - what does that mean? Does the monitor go black when you are not gaming (i.e. when web browsing or doing other desktop work), or only when gaming?
 
You need to pinpoint the issue, seeing as you are using a AMD gpu it most likely is the driver crashing and causing the screen to go to sleep which means the gpu driver crashed and did not recover.

Reinstall driver for gpu first
1. Download DDU uninstaller
2. Remove all previous driver version via DDU uninstaller
3. Reinstall latest gpu driver from AMD's website.

If the issue persists than it could also be the HDMI, or DVI, or whatever input you are using to the monitor, Check the cable leads on both ends, Replace cables and see if the issue persists and if it still happens, try to use a different monitor and see if the issue goes away.

AMD drivers tend to be buggy, AMD makes great CPU's but their gpu drivers are not always 100 percent stable.

Also check Event viewer and click on warnings and see if their is a GPU crash report if their is a report stating driver crashed then you know it was the driver

when i play for some hours When i Tab out of the game the Monitor goes blank...

If the monitor goes to sleep only after 5 hours than 9 times out of 10 it's probably NOT the Monitor, my best guess would be the HDMI port on the graphics card or DVI port or whatever your using for input is going bad. Try switching to another port and see if the problem goes away.

Seeing as you are currently using a AMD gpu i hate to say it but AMD's drivers have a tendency to break themselves, try removing the current driver via DDU uninstaller and reinstall the latest drivers. AMD has a history of releasing broken drivers and this no hate towards them as they make fantastic CPU's, just their drivers are not the greatest.
yeah, i know they have shitty drivers, Thanks ill do!

Okay, so it only happens when you alt-tab out of the game? Or can it also happen if you're just playing? Are you playing in fullscreen or borderless windowed fullscreen mode? If the former, try the latter (as it makes it much easier to switch in and out of the game). Regardless, that does indeed make it sound like a driver issue. Might be the driver itself or it might be your game(s) not handling the switch to the desktop properly and thus crashing the driver. Regardless, a DDU reinstall is a good starting point.

Just because its AMD doesn't mean what you say is always the case. This guys monitor maybe shot.

Run Radeon Pro for Enterprise Drivers.

Here you go for your ignorance, also there are several coming here wondering why their rtx 2000 series gpu fans are reving up and down.

This guys monitor is blanking out but he has a 2070.

I have no other Monitor
Then as I said way up in post #2, try a TV then. All this other talk is wasting time. You need to determine if the problem is in your monitor, or your computer. And the ONLY way to do that is to try a different monitor (or TV) on this computer.
 
Can you check if any capacitors in the power supply section are bulging?
uh i will try i havent done that and i dont know how

He was responding to the poster who implied your problems were due to the fact you have an AMD graphics card. That just is not true. NVIDIA cards can just as easily have driver, GPU crashing, and sleep issues too.

Yup, yesterday i told someone to rma their rtx 2000 series gpu due to it causing a a crash with a gpu light to occur multiple times on their mobo, not to mention several with rtx 2000 series cards the fans reving up and down in a endless cycle.

For a new member to come spout crap is unnecessary
