Laptop To External Monitor Randomly Goes to Sleep?

Laptop is asus u45jc-a1. I had this laptop for many years already, like it b/c its small and thin type and 14.1. Laptop is slow when playing many tables with hem2 and tn1.


However, the bigger issue i have with this is last year i noticed that when i first bought a new hp 24' monitor with 1920x1200 resolution, it would randomly go to sleep. Issue with this is when im playing many tables, once this happens, i sit out every table and then it takes 90 seconds or so before i can fix it. I would have to wait till my computer's power goes off. Then i click power button then it would resume windows.


At first i thought this was my new HP monitor. The thing is after some time, this rarely happened. But when it does, it would happen few times a day, it could be once every hour but rarely would go black more than a few times a day. Sometimes it would go black, then go back to normal then go black again after 20 minutes. Some days it wouldn't happen even once but its rare. Note my laptop is on all day.


It wasn't until i came back to the usa and used my dell 2007fp monitor that i noticed i had the same issue. It would randomly turn off and only way to turn back on was to wait like 90 seconds for computer to turn off, then click power to resume windows. Note previously what i did when this happened was hold the power button and wait and release. What of course happened was the laptop would turn off then powering it on again... it would show starting windows instead of resuming windows so i never did this ever again. So at this point, i figure it cannot be the monitor then. I then tested another monitor this time an acer one but this laptop is many years old... same issue.


Does that mean this is 100 percent my laptop? HP monitor which bought brand new had this issue. I googled hp monitor going to sleep and many ppl who have hp monitor say similar thing so i figure its the monitor. Then i used an old dell 2007fp and same issue, then acer one same issue so this isn't a coincidence right?


Someone in a forum told me this has to be a driver issue. The thing is i tried to update my driver but what eventually happened was many times was driver installed but everytime computer restarted it would never start up and be stuck. I tried every way possible and same issue. I then read it has to do with the driver i have. Does anyone know what i can do to fix this issue? Someone else said my video card could be broken? Again this issue is very annoying especially when 20 plus tabling poker. So basically i had to play on a small laptop screen instead of connecting it to any monitor because of this.


One other thing i want to mention is hp monitor when it does this, it would say on screen monitor goes to sleep. But my dell fp 2007 or acer one, theres no message, it would just go to sleep.


Thoughts?

 

Your post is too long so I didn't read it. Sleep = never.
