In your situation you may want to consider a reasonably priced 24" monitor that uses a MVA or PVA panel. The following is a list of all 24" LCD monitors sold at Newegg.com:

Many of the less expensive monitors are using the TN panel; similar to the Gateway that you bought. All monitors under $570 as of (Oct 18, 2007) uses TN panels with the exception of the following monitors:
* Westinghouse L2410NM Glossy Black 24" 8ms ---> $380 after a $50 rebate
* DoubleSight DS-240WB Black 24" 6ms ---> $420 after a $100 rebate
* DoubleSight DS-245W Black 24" 6ms ---> $480
I never heard of Doublesight so I'm not sure how reliable their monitors are.
Westinghouse just shouts out to me as "CHEAP, CHEAP, CHEAP" in more ways than one.
My recommendation is the Planar PX2411w for $580. I currently have a 4+ year old Planar PX191 19" LCD monitor that I am still very pleased with. No problems at all. Back then they simply had
the best warranty out there. They actually had 1 dead pixel return policy. If you had to RMA a Planar LCD monitor back to them within the warranty, they would ship out a replacement monitor to you using 2-Day express delivery. You would then return your defective monitor back to Planar using the same packaging and pay no postage whatsoever. Now Planar is simply has a very good warranty policy since they no longer have that 1 dead pixel policy.

Before stepping up to looking at 26" LCD monitors using Si-IPS panels (actually there were only two: Planar PX2611w and the NEC 2690WUXi) I was considering the BenQ FP241W and FP241WZ; they were at the top of my list. Newegg only carries the FP241W. If you are looking for a monitor with lots of different video input connections, either one of these monitors is for you. It is selling for $650 after a $50 mail-in rebate.

I guess by default a lot of people in the 24" LCD market look at the Dell 2407WFP-HC that is currently selling for $670. However, Dell is known for having sales every now and then.
