Samsung monitors were very good, never had one fail in the warranty period, but all would die a spectacular death from LOPT failure after the warranty period was up ( 5 years on the LOPT and tube) but even those driven 24/7 for 5 years had good tubes up to the tip. The caps would be bulging, brown and dying, but the design still ran, but the transformers were not available.
Don't know about newer stuff, touching wood about my monitor...........
