This grow rate is lower than the earlier projections of 3.2 percent growth, Gartner said in a statement.
"Price pressure based on increased competition, lack of product differentiation and increased availability of viable alternative solutions has had a dampening effect on the short term IT spending outlook," Gartner Managing Vice President Richard Gordon said.
However, 2015 through 2018 will see a return to 'normal' spending growth levels as pricing and purchasing styles reach a new equilibrium, he added.
For 2015, Gartner expects the total IT spending to grow 3.7 per cent to USD 3.88 trillion.
"IT is entering its third phase of development, moving from a focus on technology and processes in the past to a focus in the future on new business models enabled by digitalisation," he said.
According to Gartner, spending on devices (including PCs, ultramobiles, mobile phones, tablets and printers) is forecast to grow 1.2 per cent in 2014 to USD 685 billion.
Spending on data center systems (USD 140 billion) and enterprise software (USD 321 billion) is expected to grow 0.4 per cent and 6.9 per cent, respectively.
IT services is expected to see 3.8 per cent growth to USD 967 billion, while telecom services are forecast to grow 0.7 per cent to USD 1.63 trillion during the period.
