My main monitor is LG 29UM57 , side monitor is DELL S2340L.

I would like to use the 21:9 as landscape and the 16:9 as portrait.

S2340L have no portrait stand, what suggestions do you guys have for a stand?

Otherwise, what monitors with portrait standcan you suggest ? Quality should be at least on par with the DELL s2340L. Budget RM600+200.

Just to clarify, check the back plane has any cover that covers the 100mm VESA mount holes, if it does not then sorry to say you can't use it as portrait mode.
Dell P series should fit your budget, IPS with Dell flexible stands so you don't need to get another stand for it.

Please look for user teng_08, he should have what you need

Nope, no hidden vesa mount, just a non-vesa slot hole to slot in it's own stand.
