Last week my widescreen LCD HP decided to see the PC for a few minutes ,then resort to standbye . Coul be one small PCB or major one. However ,last week ,I spotted a 17" LCD Monitor in one of the "Cash Convertor " style shops for just over a tenner . PSU was wrappe in cling film ,an ceetified as correct .

However , monitor PSU has supply in as 12v ( most probably has regulation built in on board),but since psu is getting warm ,I thought I'd check PSU ratings vs Monitor .Turns out that monitor is 12v , 3A, whilst PSU is 24v ,1.8 . Can't find the makers site on line -seems to be a contract item ( UNYSYS ) and no software /specs available .

Anyone involved in IT tell me more ( possibly old monitor,but at price not a bad buy).

My electronics background sounds alarm bells ,but ,apart from getting warm in use ,all seems to work well .

Can't offer much help with the specs, but you could fry eggs on my Apple monitor PSUs at work, and they've been fine for the last few years - on almost 24/7 (between powered-up and sleeping).

google the monitor and see what it comes back with for the PSU.

Tried that - all I get is some sort of software/hardware house .

Thought if I mentioned the name (USYS) -it might ring some bells with those IT guys .

EDIT to add - Just tried -got one IT company in India and a US Netwprk management co name ,aded monitor and there's plenty of mention of USYS monitors ,but no sign of maker .

To be fair a PSU will always generate heat, so if it's working and not being funny I'd think you're probably ok, although don't leave it on when you're out

This is just a guess and if you're driving a 12v monitor at 24v then it's going to shorten the life of some parts.

You may find the regulators they have onboard to downvolt from 12V have a range of 10V to 30V to provide a 3v3 and 5v and that becasue the 24V is in the window it will drive them ok.
